Accounting Policies [Abstract]
Organization and Significant Accounting Policies	Organization and Significant Accounting Policies Business: The TIAA Real Estate Account (“Account”) is an insurance separate account of Teachers Insurance and Annuity Association of America (“TIAA”) and was established by resolution of TIAA’s Board of Trustees (the “Board”) on February 22, 1995, under the insurance laws of the State of New York, for the purpose of funding variable annuity contracts issued by TIAA. The Account offers individual and group accumulating annuity contracts (with contributions made on a pre-tax or after-tax basis), as well as individual lifetime and term-certain variable payout annuity contracts (including the payment of death benefits to beneficiaries). Investors are entitled to transfer funds to or from the Account, and make withdrawals from the Account on a daily basis, under certain circumstances. Funds invested in the Account for each category of contract are expressed in terms of units, and unit values will fluctuate depending on the Account’s performance. The investment objective of the Account is to seek favorable total returns primarily through the rental income and appreciation of a diversified portfolio of directly held, private real estate investments and real estate-related investments while offering investors guaranteed, daily liquidity. The Account holds real estate properties directly and through subsidiaries wholly-owned by TIAA for the sole benefit of the Account. The Account also holds limited interests in real estate joint ventures and funds, as well as investments in loans receivable with real estate properties as underlying collateral. Additionally, the Account invests in real estate-related and non-real estate-related publicly traded securities, cash and other instruments to maintain adequate liquidity levels for operating expenses, capital expenditures and to fund benefit payments (withdrawals, transfers and related transactions). Interim Financial Information: The Consolidated Financial Statements of the Account as of March 31, 2022 and for the three months ended March 31, 2022 and 2021 are unaudited and include all adjustments necessary to present a fair statement of results for the interim periods presented. Results of operations for the interim periods are not necessarily indicative of results for the entire year. These Consolidated Financial Statements have been prepared in accordance with the applicable rules and regulations of the Securities and Exchange Commission (“SEC”). Accordingly, certain footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted from this report pursuant to the rules of the SEC. As a result, these Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and notes thereto included in the Account’s Annual Report on Form 10-K for the year ended December 31, 2021 (“2021 Form 10-K”). Basis of Presentation: The accompanying Consolidated Financial Statements include the Account and those subsidiaries wholly-owned by TIAA for the benefit of the Account. Certain prior period amounts have been reclassified for comparative purposes to conform to the current period financial statement presentation. These reclassifications had no effect on previously reported results of operations. All significant intercompany accounts and transactions between the Account and such subsidiaries have been eliminated. The Accumulation Unit Value (“AUV”) used for financial reporting purposes may differ from the AUV used for processing transactions. The AUV used for financial reporting purposes includes security and participant (or "contract owner") transactions effective through the period end date to which this report relates. Total return is computed based on the AUV used for processing transactions. Use of Estimates: The Consolidated Financial Statements were prepared in accordance with GAAP, which requires the use of estimates made by management. Actual results may vary from those estimates and such differences may be material. The outbreak of the novel coronavirus (commonly known as “COVID-19”) and the subsequent global pandemic began significantly impacting the U.S. and global financial markets and economies during the first quarter of 2020. During the second and third quarters of 2020, the Account received multiple requests for rent and loan payment relief as a result of the COVID-19 pandemic; however, the requests were slowed during the fourth quarter of 2020 and reasonably estimated at this time. The ultimate impact of the COVID-19 pandemic and the extent to which the COVID-19 pandemic impacts the Account’s business, results of operations, investments, and cash flows will depend on future developments, which are highly uncertain and difficult to predict. Significant Accounting Policy Updates: In the quarter ended March 31, 2022, the Account began hedging its foreign currency risk through the use of derivative instruments. The impact of this hedging activity was not material to the results of operations for the first quarter of 2022 or the Consolidated Statement of Assets and Liabilities at March 31, 2022. Other than the addition of the following accounting policy related to derivative instruments, there were no changes to the Account's significant accounting policies as described in the Account's Annual Report on Form 10-K for the year ended December 31, 2021. Foreign Currency Forwards —The Account uses foreign currency forward contracts to manage foreign currency exchange rate risk related to foreign currency-denominated investments. Foreign currency forward contracts are recorded at fair value and are reflected in Other assets or liabilities on the Consolidated Statements of Assets and Liabilities. The fair value of foreign currency forward contracts is determined using the prevailing forward exchange rate which is derived from quotes provided by an independent pricing source. Recent Accounting Pronouncements: In July 2021, the FASB issued ASU 2021-05—Leases (Topic 842): Lessors—Certain Leases with Variable Lease Payments (“ASU 2021-05”). The amendments in ASU 2021-05 amend the lease classification requirements for lessors to align them with practice under Topic 840. Lessors should classify and account for a lease with variable lease payments that do not depend on a reference index or a rate as an operating lease if certain criteria are met. When a lease is classified as operating, the lessor does not recognize a net investment in the lease, does not derecognize the underlying asset, and, therefore, does not recognize a selling profit or loss. The amendments are effective for fiscal years beginning after December 15, 2021, for all entities, and interim periods within those fiscal years for public business entities. Entities that have adopted Topic 842 before the issuance date of ASU 2016-05 have the option to apply the amendments either (1) retrospectively to leases that commenced or were modified on or after the adoption of Update 2016-02 or (2) prospectively to leases that commence or are modified on or after the date that an entity first applies the amendments. Management has adopted the guidance and it did not materially impact the Account. In March 2020, the FASB issued ASU 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”). The guidance provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference the London Interbank Offered Rate ("LIBOR") or another reference rate expected to be discontinued. The expedients and exceptions are effective for the period from March 12, 2020 through December 31, 2022. Management does not expect the guidance to materially impact the Account.

Related Party Transactions

Related Party Transactions	3 Months Ended
	Mar. 31, 2022
Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions Investment management, administrative and distribution services are provided to the Account at cost by TIAA or certain affiliates of TIAA. Services provided at cost are paid by the Account on a daily basis based upon projected expenses to be provided to the Account. Payments are adjusted periodically to ensure daily payments are as close as possible to the Account’s actual expenses incurred. Differences between actual expenses and the amounts paid by the Account are reconciled and adjusted quarterly. Investment management services for the Account are provided by TIAA officers, under the direction and control of the Board, pursuant to investment management procedures adopted by TIAA for the Account. TIAA’s investment management decisions for the Account are subject to review by the independent fiduciary. TIAA also provides various portfolio accounting and related services for the Account. The Account is a party to the Distribution Agreement for the Contracts Funded by the TIAA Real Estate Account (the “Distribution Agreement”), dated January 1, 2008, by and among TIAA, for itself and on behalf of the Account, and TIAA-CREF Individual and Institutional Services, LLC (“Services”). Services is a direct wholly-owned subsidiary of TIAA, and is registered with the SEC as a broker-dealer and a registered investment adviser and is a member of the Financial Industry Regulatory Authority. Pursuant to the Distribution Agreement, Services performs distribution services for the Account which include, among other things, (i) distribution of annuity contracts issued by TIAA and funded by the Account, (ii) advising existing annuity contract owners in connection with their accumulations and (iii) helping employers implement and manage retirement plans. In addition, TIAA performs administrative functions for the Account, which include, among other things, (i) maintaining accounting records and performing accounting services, (ii) receiving and allocating premiums, (iii) calculating and making annuity payments, (iv) processing withdrawal requests, (v) providing regulatory compliance and reporting services, (vi) maintaining the Account’s records of contract ownership and (vii) otherwise assisting generally in all aspects of the Account’s operations. Both distribution services (pursuant to the Distribution Agreement) and administrative services are provided to the Account by Services and TIAA, as applicable, on an at cost basis. The Distribution Agreement is terminable by either party upon 60 days written notice and terminates automatically upon any assignment thereof. In addition to providing the services described above, TIAA charges the Account fees to bear certain mortality and expense risks and risks with providing the liquidity guarantee. These fees are charged as a percentage of the net assets of the Account. Rates for these fees are established annually. Once an Account participant begins receiving lifetime annuity income benefits, payment levels cannot be reduced as a result of the Account’s actual mortality experience. As such, mortality and expense risk are contractual charges for TIAA’s assumption of this risk. TIAA provides the Account with a liquidity guarantee enabling the Account to have funds available to meet contract owner redemption, transfer or cash withdrawal requests. The liquidity guarantee is required by the New York State Department of Financial Services and is subject to a prohibited transaction exemption that the Account received in 1996 (96-76) from the U.S. Department of Labor (the “PTE 96-76”). The Account pays TIAA for the risk associated with providing the liquidity guarantee through a daily deduction from the Account’s net assets. Whether the liquidity guarantee is exercised is based on the cash level of the Account from time to time, as well as recent contract owner withdrawal activity and the Account’s expected working capital, debt service and cash needs, and subject to the oversight of the independent fiduciary. If the Account cannot fund contract owner withdrawal or redemption requests from the Account’s own cash flow and liquid investments, TIAA will fund them by purchasing accumulation units issued by the Account (accumulation units that are purchased by TIAA are generally referred to as “liquidity units”). TIAA guarantees that contract owners can redeem their accumulation units at the accumulation unit value next determined after their transfer or cash withdrawal request is received in good order. Liquidity units owned by TIAA are valued in the same manner as accumulation units owned by the Account’s contract owners. The independent fiduciary, which has the right to adjust the percentage of total accumulation units that TIAA’s ownership should not exceed (the “trigger point”), has established the trigger point at 45% of the outstanding accumulation units. Expenses for the services and fees described above are identified as such in the accompanying Consolidated Statements of Operations and are further identified as "Expenses" in Note 11—Financial Highlights . The Account has loans receivable outstanding with related parties as of March 31, 2022. One loan is with a joint venture partner and the other loans are with joint ventures in which the Account also has an equity interest. The loans are held at fair value in accordance with the valuation policies described in Note 1—Organization and Significant Accounting Policies of the Account's 2021 Form 10-K. The following table presents the key terms of the loans as of the reporting date (in millions): Related Party Equity Ownership Interest Interest Rate Maturity Date Fair Value at Principal March 31, 2022 December 31, 2021 2022 2021 36.5 36.5 MRA Hub 34 Holding, LLC 95.00% 2.50% + LIBOR 9/1/2022 $ 36.5 $ 36.5 0.5 0.5 MRA 34 LLC —% 3.75% + LIBOR 8/26/2022 0.5 0.5 32.8 32.8 THP Student Housing, LLC 97.00% 3.20% 9/1/2024 32.9 32.9 TOTAL LOANS RECEIVABLE WITH RELATED PARTIES $ 69.9 $ 69.9

Concentrations of Risk

Risks and Uncertainties [Abstract]
Concentrations of Risk	Concentrations of Risk Concentrations of risk may arise when a number of properties are located in a similar geographic region such that the economic conditions of that region could impact tenants’ obligations to meet their contractual obligations or cause the values of individual properties to decline. Additionally, concentrations of risk may arise if any one tenant comprises a significant amount of the Account's rent, or if tenants are concentrated in a particular industry. As of March 31, 2022, the Account had no significant concentrations of tenants as no single tenant had annual contract rent that made up more than 4% of the rental income of the Account. Moreover, the Account's tenants have no notable concentration present in any one industry. The Account’s wholly-owned real estate investments and investments in joint ventures are primarily located in the United States.

Leases [Abstract]
Leases	Leases The Account’s wholly-owned real estate properties are leased to tenants under operating lease agreements which expire on various dates through 2051. Rental income is recognized in accordance with the billing terms of the lease agreements. The leases do not have material variable payments, material residual value guarantees or material restrictive covenants. Certain leases have the option to extend or terminate at the tenant's discretion, with termination options resulting in additional fees due to the Account. Aggregate minimum annual rentals for wholly-owned real estate investments owned by the Account through the non-cancelable lease term, excluding short-term residential leases, as of March 31, 2022 and December 31, 2021 are as follows (in millions): As of Years Ended March 31, 2022 December 31, 2021 2022 $ 477.4 (1) $ 635.8 2023 599.7 594.2 2024 526.2 517.7 2025 445.5 436.1 2026 341.2 330.2 Thereafter 1,207.0 1,172.7 Total $ 3,597.0 $ 3,686.7 (1) Representative of minimum rents owed for the remaining months of the calendar year ending December 31, 2022. Certain leases provide for additional rental amounts based upon the recovery of actual operating expenses in excess of specified base amounts, sales volume or contractual increases as defined in the lease agreement. These contractual contingent rentals are not included in the table above. The Account has ground leases for which the Account is the lessee. The leases do not contain material residual value guarantees or material restrictive covenants. The fair value of right-of-use assets and leases liabilities related to ground leases are reflected on the balance sheet within other assets and other liabilities, respectively. The fair values and key terms of the right-of-use assets and lease liabilities related to the Account's ground leases are as follows (in millions): As of March 31, 2022 December 31, 2021 Assets: Right-of-use assets, at fair value $ 38.6 $ 40.3 Liabilities: Ground lease liabilities, at fair value $ 38.6 $ 40.3 Key Terms: Weighted-average remaining lease term (years) 67.9 69.5 Weighted-average discount rate (1) 7.71 % 7.71 % (1) Discount rates are reflective of the rates utilized during the most recent appraisal of the associated real estate investments. For the three months ended March 31, 2022 and 2021, operating lease costs related to ground leases were $0.5 million and $0.6 million, respectively. These costs include variable lease costs, which are immaterial. Aggregate future minimum annual payments for ground leases held by the Account are as follows (in millions): As of March 31, 2022 December 31, 2021 Years Ended 2022 $ 1.7 $ 2.3 2023 2.4 2.3 2024 2.5 2.4 2025 2.5 2.4 2026 2.5 2.4 Thereafter 438.4 414.0 Total $ 450.0 $ 425.8 In April 2020, the FASB staff released guidance focused on treatment of concessions related to the effects of the COVID-19 pandemic on the application of lease modification guidance in Accounting Standards Codification (“ASC”) 842, “Leases.” The guidance provides a practical expedient to forgo the associated reassessments required by ASC 842 when changes to a lease result in similar or lower future consideration. There was no material exposure to rent concessions or lease defaults for tenants impacted by the COVID-19 pandemic for the three months ended March 31, 2022.

The leases do not contain material residual value guarantees or material restrictive covenants. The fair value of right-of-use assets and leases liabilities related to ground leases are reflected on the balance sheet within other assets and other liabilities, respectively. The fair values and key terms of the right-of-use assets and lease liabilities related to the Account's ground leases are as follows (in millions): As of March 31, 2022 December 31, 2021 Assets: Right-of-use assets, at fair value $ 38.6 $ 40.3 Liabilities: Ground lease liabilities, at fair value $ 38.6 $ 40.3 Key Terms: Weighted-average remaining lease term (years) 67.9 69.5 Weighted-average discount rate (1) 7.71 % 7.71 % (1) Discount rates are reflective of the rates utilized during the most recent appraisal of the associated real estate investments. For the three months ended March 31, 2022 and 2021, operating lease costs related to ground leases were $0.5 million and $0.6 million, respectively. These costs include variable lease costs, which are immaterial. Aggregate future minimum annual payments for ground leases held by the Account are as follows (in millions): As of March 31, 2022 December 31, 2021 Years Ended 2022 $ 1.7 $ 2.3 2023 2.4 2.3 2024 2.5 2.4 2025 2.5 2.4 2026 2.5 2.4 Thereafter 438.4 414.0 Total $ 450.0 $ 425.8 In April 2020, the FASB staff released guidance focused on treatment of concessions related to the effects of the COVID-19 pandemic on the application of lease modification guidance in Accounting Standards Codification (“ASC”) 842, “Leases.” The guidance provides a practical expedient to forgo the associated reassessments required by ASC 842 when changes to a lease result in similar or lower future consideration. There was no material exposure to rent concessions or lease defaults for tenants impacted by the COVID-19 pandemic for the three months ended March 31, 2022.

Fair Value Disclosures [Abstract]
Assets and Liabilities Measured at Fair Value on a Recurring Basis	Assets and Liabilities Measured at Fair Value on a Recurring Basis Valuation Hierarchy: The Account’s fair value measurements are grouped into three levels, as defined by the FASB. The levels are defined as follows: • Level 1 fair value inputs are quoted prices for identical items in active, liquid and visible markets such as stock exchanges. • Level 2 fair value inputs are observable information for similar items in active or inactive markets, and appropriately consider counterparty creditworthiness in the valuations. • Level 3 fair value inputs reflect our best estimate of inputs and assumptions market participants would use in pricing an asset or liability at the measurement date. The inputs are unobservable in the market and significant to the valuation estimate. An investment’s categorization within the valuation hierarchy described above is based upon the lowest level of input that is significant to the fair value measurement. Real estate fund investments are excluded from the valuation hierarchy, as these investments are fair valued using their net asset value as a practical expedient since market quotations or values from independent pricing services are not readily available. See Note 1 — Organization and Significant Accounting Policies of the Account's 2021 Form 10-K for further discussion regarding the use of a practical expedient for the valuation of real estate funds. The following tables show the major categories of assets and liabilities measured at fair value on a recurring basis as of March 31, 2022 and December 31, 2021, using unadjusted quoted prices in active markets for identical assets (Level 1); significant other observable inputs (Level 2); and significant unobservable inputs (Level 3); and fair value using the practical expedient (millions): Description Level 1: Quoted Prices in Active Markets for Identical Assets Level 2: Significant Other Observable Inputs Level 3: Significant Unobservable Inputs Fair Value Using Practical Expedient Total at March 31, 2022 Real estate properties $ — $ — $ 20,179.1 $ — $ 20,179.1 Real estate joint ventures — — 7,253.3 — 7,253.3 Real estate funds — — — 805.8 805.8 Real estate operating business — — 487.6 — 487.6 Marketable securities: U.S. government agency notes — 1,076.5 — — 1,076.5 Foreign government agency notes — 17.1 — — 17.1 U.S. treasury securities — 875.2 — — 875.2 Corporate bonds — 572.4 — — 572.4 Loans receivable (1) — — 1,329.2 — 1,329.2 Total Investments at March 31, 2022 $ — $ 2,541.2 $ 29,249.2 $ 805.8 $ 32,596.2 Loans payable $ — $ — $ (2,338.0) $ — $ (2,338.0) Line of credit $ — $ — $ (500.0) $ — $ (500.0) Description Level 1: Quoted Prices in Active Markets for Identical Assets Level 2: Significant Other Observable Inputs Level 3: Significant Unobservable Inputs Fair Value Using Practical Expedient Total at December 31, 2021 Real estate properties $ — $ — $ 18,903.9 $ — $ 18,903.9 Real estate joint ventures — — 7,175.9 — 7,175.9 Real estate funds — — — 811.5 811.5 Real estate operating business — — 326.3 — 326.3 Marketable securities: U.S. government agency notes — 864.1 — — 864.1 Foreign government agency notes — 7.6 — — 7.6 U.S. treasury securities — 784.3 — — 784.3 Corporate bonds — 551.8 — 551.8 Loans receivable (1) — — 1,492.6 — 1,492.6 Total Investments at December 31, 2021 $ — $ 2,207.8 $ 27,898.7 $ 811.5 $ 30,918.0 Loans payable $ — $ — $ (2,380.5) $ — $ (2,380.5) Line of credit $ — $ — $ (500.0) $ — $ (500.0) (1) Includes loans receivable with related parties.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Investments in Real Estate Funds	Investments in Real Estate Funds The Account has ownership interests in real estate funds (each a “Fund”, and collectively the “Funds”). The Funds are setup as limited partnerships or entities similar to a limited partnership, and as such, meet the definition of a VIE as the limited partners collectively lack the power, through voting or similar rights, to direct the activities of the Fund that most significantly impact the Fund's economic performance. Management has determined that the Account is not the primary beneficiary for any of the Funds, as the Account lacks the power to direct the activities of each Fund that most significantly impact the respective Fund's economic performance, and the Account further lacks substantive kick-out rights to remove the entity with these powers. Refer to Note 1—Organization and Significant Accounting Policies of the Account's 2021 Form 10-K for a description of the methodology used to determine the primary beneficiary of a VIE. No financial support (such as loans or financial guarantees) was provided to the Funds during the three months ended March 31, 2022. The Account is contractually obligated to make additional capital contributions in certain Funds in future years. These commitments are included in the maximum exposure to loss presented below.

Receivables [Abstract]
Loans Receivable	Loans Receivable The Account’s loan receivable portfolio is primarily comprised of mezzanine loans secured by the borrower’s direct and indirect interests in commercial real estate. Mezzanine loans are subordinate to first mortgages on the underlying real estate collateral. The following property types represent the underlying real estate collateral for the Account's mezzanine loans (in millions): March 31, 2022 December 31, 2021 Principal Outstanding Fair Value % of Fair Value Principal Outstanding Fair Value % of Fair Value Office (1) $ 867.4 $ 858.1 64.6 % $ 862.4 $ 853.4 57.2 % Apartments (1) 253.5 252.1 19.0 % 253.3 252.0 16.9 % Industrial — — — % 161.4 161.3 10.8 % Hotel 125.2 125.3 9.4 % 125.3 125.3 8.4 % Retail 93.7 93.7 7.0 % 101.7 100.6 6.7 % $ 1,339.8 $ 1,329.2 100.0 % $ 1,504.1 $ 1,492.6 100.0 % (1) Includes loans receivable with related parties. The Account monitors the risk profile of the loan receivable portfolio with the assistance of a third-party rating service that models the loans and assigns risk ratings based on inputs such as loan-to-value ratios, yields, credit quality of the borrowers, property types of the collateral, geographic and local market dynamics, physical condition of the collateral, and the underlying structure of the loans. Ratings for loans are updated monthly. Assigned ratings can range from AAA to C, with an AAA designation representing debt with the lowest level of credit risk and C representing a greater risk of default or principal loss. Loans that are more than 90 days past due are classified as delinquent and assigned a D rating. Mezzanine debt in good health is typically reflective of a risk rating in the B range (e.g., BBB, BB, or B), as these ratings reflect borrowers' having adequate financial resources to service their financial commitments, but also acknowledging that adverse economic conditions, should they occur, would likely impede on a borrowers' ability to pay. All borrowers of loans rated C or higher are current as of March 31, 2022. The following table presents the fair values of the Account's loan portfolio based on the risk ratings as of March 31, 2022 (in millions), listed in order of the strength of the risk rating (from strongest to weakest): March 31, 2022 December 31, 2021 Number of Loans Fair Value % of Fair Value Number of Loans Fair Value % of Fair Value AA — — — % 1 62.6 4.2 % A 2 195.4 14.7 % 4 248.5 16.6 % A- 1 51.4 3.9 % — — — % BBB 2 102.1 7.7 % 6 374.7 25.1 % BBB- 4 117.3 8.8 % — — — % BB+ 5 197.1 14.8 % — — — % BB 3 156.6 11.8 % 10 437.8 29.3 % BB- 2 129.1 9.7 % — — — % B+ 2 74.7 5.6 % — — — % B 2 77.1 5.8 % 5 144.3 9.7 % C 2 158.5 11.9 % 2 154.8 10.4 % NR (1) 3 69.9 5.3 % 3 69.9 4.7 % 28 $ 1,329.2 100.0 % 31 $ 1,492.6 100.0 % (1) "NR" designates loans not assigned an internal credit rating.

Debt Disclosure [Abstract]
Line of Credit	Line of Credit The Account has a senior revolving unsecured line of credit with a syndicate of third-party bank lenders, including JPMorgan Chase Bank, N.A. (“Credit Agreement”) with a maximum total commitment of $500.0 million. Draws against the Credit Agreement can take the form of Eurodollar Loans or Alternate Base Rate Loans (“ABR Loans”). Eurodollar Loans and ABR Loans require a minimum funding of $5.0 million. The Account previously held an unused, stand-alone, $500.0 million unsecured line of credit scheduled to mature in August 2021 that was terminated in May 2021. Eurodollar Loans are issued for a term of twelve months or less and bear interest during the period (“Interest Period”) at a rate equal to the Adjusted London Interbank Offered Rate (“Adjusted LIBOR”) plus a spread (the “Eurodollar Applicable Rate”), with the spread dependent upon the leverage ratio of the Account. Adjusted LIBOR is calculated by multiplying the Statutory Reserve Rate, as determined by the Federal Reserve Board for Eurodollar liabilities, by LIBOR, as determined by the Intercontinental Exchange on the date of issuance that corresponds to the length of the Interest Period. The Account may prepay Eurodollar Loans at any time during the life of the loan without penalty. The Account is limited to five active Eurodollar Loans on the Credit Agreement; however, the Account may retire and initiate new Eurodollar Loans without restriction so long as the total number of loans in active status does not exceed the limit. ABR Loans are issued for a specific length of time and bear interest at a rate equal to the highest rate among the following calculations plus a spread (the "ABR Applicable Rate"), with the spread dependent on the leverage ratio of the Account: (i) the Prime Rate on the date of issuance, with the Prime Rate being defined as the rate of interest last quoted by the Wall Street Journal as the Prime Rate; (ii) the Federal Reserve Bank of New York (“NYFRB”) rate as provided by the NYFRB on the date of issuance plus 0.5%; or (iii) the Adjusted LIBOR rate plus 1.0%. The Account may prepay ABR Loans at any time during the life of the loan without penalty. As of March 31, 2022, the Account was in compliance with all covenants required by the Credit Agreement. The following table provides a summary of the key characteristics of the Credit Agreement as of March 31, 2022: Current Balance (in millions) $ 500.0 Maximum Capacity (in millions) $ 500.0 Inception Date September 20, 2018 Maturity Date September 20, 2022 (1) Extension Option Yes (1) Eurodollar Applicable Rate Range 0.85% - 1.05% ABR Applicable Rate Range 0.85% - 1.05% Unused Fee (2) 0.20% per annum (1) On July 16, 2021, the Account exercised its option to extend the commitment terms until September 20, 2022, with one consecutive twelve (2) The Account is charged a fee on the unused portion of the Credit Agreement.

Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation: The accompanying Consolidated Financial Statements include the Account and those subsidiaries wholly-owned by TIAA for the benefit of the Account. Certain prior period amounts have been reclassified for comparative purposes to conform to the current period financial statement presentation. These reclassifications had no effect on previously reported results of operations. All significant intercompany accounts and transactions between the Account and such subsidiaries have been eliminated. The Accumulation Unit Value (“AUV”) used for financial reporting purposes may differ from the AUV used for processing transactions. The AUV used for financial reporting purposes includes security and participant (or "contract owner") transactions effective through the period end date to which this report relates. Total return is computed based on the AUV used for processing transactions.
Significant Accounting Policy Updates and Recent Accounting Pronouncements	Significant Accounting Policy Updates: In the quarter ended March 31, 2022, the Account began hedging its foreign currency risk through the use of derivative instruments. The impact of this hedging activity was not material to the results of operations for the first quarter of 2022 or the Consolidated Statement of Assets and Liabilities at March 31, 2022. Other than the addition of the following accounting policy related to derivative instruments, there were no changes to the Account's significant accounting policies as described in the Account's Annual Report on Form 10-K for the year ended December 31, 2021. Foreign Currency Forwards —The Account uses foreign currency forward contracts to manage foreign currency exchange rate risk related to foreign currency-denominated investments. Foreign currency forward contracts are recorded at fair value and are reflected in Other assets or liabilities on the Consolidated Statements of Assets and Liabilities. The fair value of foreign currency forward contracts is determined using the prevailing forward exchange rate which is derived from quotes provided by an independent pricing source. Recent Accounting Pronouncements: In July 2021, the FASB issued ASU 2021-05—Leases (Topic 842): Lessors—Certain Leases with Variable Lease Payments (“ASU 2021-05”). The amendments in ASU 2021-05 amend the lease classification requirements for lessors to align them with practice under Topic 840. Lessors should classify and account for a lease with variable lease payments that do not depend on a reference index or a rate as an operating lease if certain criteria are met. When a lease is classified as operating, the lessor does not recognize a net investment in the lease, does not derecognize the underlying asset, and, therefore, does not recognize a selling profit or loss. The amendments are effective for fiscal years beginning after December 15, 2021, for all entities, and interim periods within those fiscal years for public business entities. Entities that have adopted Topic 842 before the issuance date of ASU 2016-05 have the option to apply the amendments either (1) retrospectively to leases that commenced or were modified on or after the adoption of Update 2016-02 or (2) prospectively to leases that commence or are modified on or after the date that an entity first applies the amendments. Management has adopted the guidance and it did not materially impact the Account. In March 2020, the FASB issued ASU 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting (“ASU 2020-04”). The guidance provides optional expedients and exceptions for applying generally accepted accounting principles to contract modifications and hedging relationships, subject to meeting certain criteria, that reference the London Interbank Offered Rate ("LIBOR") or another reference rate expected to be discontinued. The expedients and exceptions are effective for the period from March 12, 2020 through December 31, 2022. Management does not expect the guidance to materially impact the Account.
