Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The unaudited Consolidated Financial Statements have been prepared by The Interpublic Group of Companies, Inc. and its subsidiaries (the “Company,” “IPG,” “we,” “us” or “our”) in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the Securities and Exchange Commission (the “SEC”) for reporting interim financial information on Form 10-Q. Accordingly, they do not include certain information and disclosures required for complete financial statements. The effects of the coronavirus ("COVID-19") pandemic have impacted and will likely continue to impact our results of operations, cash flows and financial position. The Company’s Consolidated Financial Statements presented herein reflect the latest estimates and assumptions made by management that affect the reported amounts of assets and liabilities and related disclosures as of the date of the consolidated financial statements and reported amounts of revenue and expenses during the reporting periods presented. The Company believes it has used reasonable estimates and assumptions to assess the fair values of goodwill, long-lived assets and indefinite-lived intangible assets; assessment of the annual effective tax rate; valuation of deferred income taxes and allowance for expected credit losses on future uncollectible accounts receivable. Actual results could differ from these estimates and assumptions. The consolidated results for interim periods are not necessarily indicative of results for the full year and should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2021 (the “2021 Annual Report”). Effective January 1, 2022, the Company completed a managerial and operational review, which resulted in organizational realignments to our financial reporting segment structure. As a result, the Company determined we conduct our business across three reportable segments described in Note 11. The three reportable segments are: Media, Data & Engagement Solutions ("MD&E"), Integrated Advertising & Creativity Led Solutions ("IA&C"), and Specialized Communications & Experiential Solutions ("SC&E"). In conjunction with the new reporting structure, the Company has recast certain prior period amounts, wherever applicable, to reflect our revised organizational alignment. This change does not impact the unaudited consolidated statements of operations and comprehensive income, consolidated balance sheets, consolidated statement of cash flows and consolidated statements of stockholders' equity for any of the previously reported periods. Cost of services is comprised of the expenses of our revenue-producing reportable segments, MD&E, IA&C, and SC&E, including salaries and related expenses, office and other direct expenses and billable expenses, and includes an allocation of the centrally managed expenses from our "Corporate and Other" group. Office and other direct expenses include rent expense, professional fees, certain expenses incurred by our staff in servicing our clients and other costs directly attributable to client engagements. Selling, general and administrative expenses are primarily the unallocated expenses from Corporate and Other, excluding depreciation and amortization. Depreciation and amortization of fixed assets and intangible assets of the Company is disclosed as a separate operating expense. Restructuring charges in 2022 consist of adjustments to the Company's restructuring actions taken during 2020 to lower our operating expenses structurally and permanently relative to revenue and to accelerate the transformation of our business, as discussed further in Note 7. Restructuring charges mainly include severance and termination costs and lease impairment costs. In the opinion of management, these unaudited Consolidated Financial Statements include all adjustments, consisting only of normal and recurring adjustments necessary for a fair statement of the information for each period contained therein. Certain reclassifications have been made to prior-period financial statements to conform to the current-period presentation.

Contract liabilities relate to advance consideration received from customers under the terms of our contracts primarily related to reimbursements of third-party expenses, whether we act as principal or agent, and to a lesser extent, periodic retainer fees, both of which are generally recognized shortly after billing. The majority of our contracts are for periods of one year or less with the exception of our data management contracts. For those contracts with a term of more than one year, we had approximately $556.2 of unsatisfied performance obligations as of March 31, 2022, which will be recognized as services are performed over the remaining contractual terms through 2027.

Refer to Note 12 for details. Credit Agreement We maintain a committed corporate credit facility, originally dated as of July 18, 2008, which has been amended and restated from time to time (the "Credit Agreement"). We use our Credit Agreement to increase our financial flexibility, to provide letters of credit primarily to support obligations of our subsidiaries and to support our commercial paper program. On November 1, 2021, we amended and restated the Credit Agreement. As amended, among other things, the maturity date of the Credit Agreement was extended to November 1, 2026 and the cost structure of the Credit Agreement was changed. The Credit Agreement continues to include a required leverage ratio of not more than 3.50 to 1.00, among other customary covenants, including limitations on our liens and the liens of our consolidated subsidiaries and limitations on the incurrence of subsidiary debt. At the election of the Company, the leverage ratio may be changed to not more than 4.00 to 1.00 for four consecutive quarters, beginning with the fiscal quarter in which there is an occurrence of one or more acquisitions with an aggregate purchase price of at least $200.0. The Credit Agreement is a revolving facility, under which amounts borrowed by us or any of our subsidiaries designated under the Credit Agreement may be repaid and reborrowed, subject to an aggregate lending limit of $1,500.0, or the equivalent in other currencies. The Company has the ability to increase the commitments under the Credit Agreement from time to time by an additional amount of up to $250.0, provided the Company receives commitments for such increases and satisfies certain other conditions. The aggregate available amount of letters of credit outstanding may decrease or increase, subject to a sublimit of $50.0, or the equivalent in other currencies. Our obligations under the Credit Agreement are unsecured. The Credit Agreement includes covenants that, among other things, (i) limit our liens and the liens of our consolidated subsidiaries, and (ii) limit subsidiary debt. The Credit Agreement also contains a financial covenant that requires us to maintain a certain leverage ratio on a consolidated basis as of the end of each fiscal quarter. As of March 31, 2022, there were no borrowings under the Credit Agreement; however, we had $10.6 of letters of credit under the Credit Agreement, which reduced our total availability to $1,489.4. We were in compliance with all of our covenants in the Credit Agreement as of March 31, 2022. Uncommitted Lines of Credit We also have uncommitted lines of credit with various banks that permit borrowings at variable interest rates and that are primarily used to fund working capital needs. We have guaranteed the repayment of some of these borrowings made by certain subsidiaries. If we lose access to these credit lines, we would have to provide funding directly to some of our operations. As of March 31, 2022, the Company had uncommitted lines of credit in an aggregate amount of $861.4, under which we had outstanding borrowings of $59.1 classified as short-term borrowings on our Consolidated Balance Sheet. The average amount outstanding during the first quarter of 2022 was $51.4 with a weighted-average interest rate of approximately 4.7%. Commercial Paper The Company is authorized to issue unsecured commercial paper up to a maximum aggregate amount outstanding at any time of $1,500.0. Borrowings under the program are supported by the Credit Agreement described above. Proceeds of the commercial paper are used for working capital and general corporate purposes, including the repayment of maturing indebtedness and other short-term liquidity needs. The maturities of the commercial paper vary but may not exceed 397 days from the date of issue. During the first quarter of 2022, there was no commercial paper activity and, as of March 31, 2022, there was no commercial paper outstanding.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the three months ended March 31, 2022, our income tax expense was positively impacted by excess tax benefits on employee share-based payments, the majority of which is typically recognized in the first quarter due to the timing of the vesting of awards, partially offset by net losses on sales of businesses and the classification of certain assets as held for sale for which we received minimal tax benefit. We have various tax years under examination by tax authorities in various countries, and in various states, in which we have significant business operations. It is not yet known whether these examinations will, in the aggregate, result in our paying additional taxes. We believe our tax reserves are adequate in relation to the potential for additional assessments in each of the jurisdictions in which we are subject to taxation. We regularly assess the likelihood of additional tax assessments in those jurisdictions and, if necessary, adjust our reserves as additional information or events require. With respect to all tax years open to examination by U.S. federal, various state and local, and non-U.S. tax authorities, we currently anticipate that total unrecognized tax benefits will decrease by an amount between $35.0 and $45.0 in the next twelve months, a portion of which will affect our effective income tax rate, primarily as a result of the settlement of tax examinations and the lapsing of statutes of limitations. We are effectively settled with respect to U.S. federal income tax audits through 2016. With limited exceptions, we are no longer subject to state and local income tax audits for years prior to 2013 or non-U.S. income tax audits for years prior to 2010.

Restructuring Charges [Abstract]
Restructuring and Related Activities Disclosure [Text Block]	Restructuring Charges Beginning in the second quarter of 2020, the Company took restructuring actions to lower its operating expenses structurally and permanently relative to revenue and to accelerate the transformation of our business (the “2020 Restructuring Plan”). These actions continued through the fourth quarter of 2020, and most were based on our recent experience and learning in the COVID-19 pandemic and a resulting review of our operations to address certain operating expenses such as occupancy expense and salaries and related expenses. Lease impairment costs, which relate to the office spaces that were vacated as part of the 2020 Restructuring Plan, included impairments of operating lease right-of-use assets and associated leasehold improvements, furniture and asset retirement obligations in addition to losses and gains related to early lease terminations. Lease impairments were calculated based on estimated fair values using market participant assumptions including forecasted net discounted cash flows related to the operating lease right-of-use assets. All restructuring actions were identified and initiated in 2020, with all actions completed by the end of the fourth quarter of 2020. The amounts for the three months ended March 31, 2022 are adjustments to the actions taken in 2020. The components of the restructuring charges related to the 2020 Restructuring Plan are listed below. Three months ended 2022 2021 Severance and termination costs $ 0.3 $ 1.5 Lease impairment costs 5.3 (0.4) Other restructuring costs 1.0 0.2 Total restructuring charges $ 6.6 $ 1.3 Net restructuring charges were comprised of $6.1 at IA&C and $0.4 at SC&E for the three months ended March 31, 2022, which include non-cash lease impairment costs of $5.1 at IA&C and $0.2 at SC&E. Net restructuring charges were comprised of $0.4 at IA&C and $0.9 at SC&E for the three months ended March 31, 2021. A summary of the restructuring activities taken in the first three months of 2022 related to the 2020 Restructuring Plan is as follows: 2020 Restructuring Plan Liability at December 31, 2021 Restructuring Expense Non-Cash Items Cash Payments Liability at March 31, 2022 Severance and termination costs $ 9.4 $ 0.3 $ 0.0 $ 4.8 $ 4.9 Lease impairment costs 0.0 5.3 5.3 0.0 0.0 Other restructuring costs 0.0 1.0 1.0 0.0 0.0 Total $ 9.4 $ 6.6 $ 6.3 $ 4.8 $ 4.9

Segment Reporting [Abstract]
Segment Reporting Disclosure	Segment Information During the quarter ended March 31, 2022, we adjusted our segment reporting to reflect our new organizational structure effective January 1, 2022. A managerial and operational review, as well as several organizational initiatives, completed on January 1, 2022, has resulted in modifications to our organizational and segment structure. As a result, we have determined we operate our results across three reportable segments: MD&E, IA&C, and SC&E. MD&E primarily provides, and is distinguished by innovative capabilities and scale in, global media and communications services, digital services and products, advertising and marketing technology, e‐commerce services, data management and analytics, strategic consulting, and digital brand experience. MD&E is comprised of IPG Mediabrands, Acxiom, and Kinesso, as well as our digital and commerce specialist agencies, which include MRM, R/GA, and Huge. IA&C primarily provides advertising, corporate and brand identity services, and strategic consulting. IA&C is distinguished by the leading role of complex integrations of ideation and the execution of advertising and creative campaigns across all communications channels that are foundational to client brand identities. IA&C is comprised of leading global networks and agencies that provide a broad range of services, including McCann Worldgroup, IPG Health, MullenLowe Group, Foote, Cone & Belding ("FCB"), and our domestic integrated agencies. SC&E primarily provides best-in-class global public relations and other specialized communications services, events, sports and entertainment marketing, and strategic consulting. SC&E is comprised of agencies that provide a range of marketing services expertise, including IPG DXTRA and DXTRA Health, Weber Shandwick, Golin, and our sports, entertainment, and experiential agencies. We also report results for the Corporate and Other group. In conjunction with the new reporting structure, prior period segment disclosures have been recast to reflect our new reportable segments, as well as the way performance is internally managed and monitored. We continue to evaluate our financial reporting structure, and the profitability measure, employed by our chief operating decision maker for allocating resources to operating divisions and assessing operating division performance, is segment EBITA. Summarized financial information concerning our reportable segments is shown in the following table. Three months ended 2022 2021 Total revenue: MD&E $ 955.8 $ 871.5 IA&C 1,054.2 953.9 SC&E 558.5 431.6 Total $ 2,568.5 $ 2,257.0 Net revenue: MD&E $ 932.1 $ 849.8 IA&C 958.8 875.7 SC&E 336.3 302.2 Total $ 2,227.2 $ 2,027.7 Segment EBITA 1 : MD&E $ 101.4 $ 135.8 IA&C 130.5 118.1 SC&E 56.0 40.8 Corporate and Other (20.9) (30.1) Total $ 267.0 $ 264.6 Amortization of acquired intangibles: MD&E $ 17.9 $ 18.0 IA&C 2.4 2.6 SC&E 1.0 1.0 Corporate and Other 0.0 0.0 Total $ 21.3 $ 21.6 Depreciation and amortization 2 : MD&E $ 26.2 $ 24.6 IA&C 14.7 16.5 SC&E 4.1 4.6 Corporate and Other 1.5 1.9 Total $ 46.5 $ 47.6 Capital expenditures: MD&E $ 16.0 $ 13.0 IA&C 6.0 8.7 SC&E 0.8 0.7 Corporate and Other 7.9 5.9 Total $ 30.7 $ 28.3 1 Adjusted EBITA is calculated as net income available to IPG common stockholders before provision for (benefit of) income taxes, total (expenses) and other income, equity in net income (loss) of unconsolidated affiliates, net income attributable to non-controlling interests and amortization of acquired intangibles. 2 Excludes amortization of acquired intangibles.

Fair Value Measurements (Notes)

Fair Value Measurements (Notes)	3 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Fair Value Measurements Authoritative guidance for fair value measurements establishes a fair value hierarchy which requires us to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. There are three levels of inputs that may be used to measure fair value: Level 1 Unadjusted quoted prices in active markets for identical assets or liabilities. An active market for the asset or liability is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis. Level 2 Observable inputs other than Level 1 prices, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Financial Instruments that are Measured at Fair Value on a Recurring Basis We primarily apply the market approach to determine the fair value of financial instruments that are measured at fair value on a recurring basis. There were no changes to our valuation techniques used to determine the fair value of financial instruments during the three months ended March 31, 2022. The following tables present information about our financial instruments measured at fair value on a recurring basis as of March 31, 2022 and December 31, 2021, and indicate the fair value hierarchy of the valuation techniques utilized to determine such fair value. March 31, 2022 Balance Sheet Classification Level 1 Level 2 Level 3 Total Assets Cash equivalents $ 1,221.2 $ 0.0 $ 0.0 $ 1,221.2 Cash and cash equivalents Liabilities Contingent acquisition obligations 1 $ 0.0 $ 0.0 $ 33.6 $ 33.6 Accrued liabilities and Other non-current liabilities December 31, 2021 Balance Sheet Classification Level 1 Level 2 Level 3 Total Assets Cash equivalents $ 2,391.8 $ 0.0 $ 0.0 $ 2,391.8 Cash and cash equivalents Liabilities Contingent acquisition obligations 1 $ 0.0 $ 0.0 $ 33.5 $ 33.5 Accrued liabilities and Other non-current liabilities 1 Contingent acquisition obligations includes deferred acquisition payments and unconditional obligations to purchase additional non-controlling equity shares of consolidated subsidiaries. Fair value measurement of the obligations is based upon actual and projected operating performance targets as specified in the related agreements. The increase in this balance of $0.1 from December 31, 2021 to March 31, 2022 is primarily due to the exercises of redeemable non-controlling interest and valuation adjustments, offset by payments related to our deferred acquisitions payments from prior-year acquisitions. The amounts payable within the next twelve months are classified in accrued liabilities; any amounts payable thereafter are classified in other non-current liabilities. Financial Instruments that are not Measured at Fair Value on a Recurring Basis The following table presents information about our financial instruments that are not measured at fair value on a recurring basis as of March 31, 2022 and December 31, 2021, and indicates the fair value hierarchy of the valuation techniques utilized to determine such fair value. March 31, 2022 December 31, 2021 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Total long-term debt $ 0.0 $ 2,968.7 $ 40.4 $ 3,009.1 $ 0.0 $ 3,295.6 $ 41.8 $ 3,337.4 Our long-term debt is comprised of senior notes and other notes payable. The fair value of our senior notes, which are traded over-the-counter, is based on quoted prices in markets that are not active. Therefore, these senior notes are classified as Level 2. Our other notes payable are not actively traded, and their fair value is not solely derived from readily observable inputs. The fair value of our other notes payable is determined based on a discounted cash flow model and other proprietary valuation methods, and therefore is classified as Level 3. See Note 3 for further information on our long-term debt. The discount rates used as significant unobservable inputs in the Level 3 fair value measurements of our contingent acquisition obligations and long-term debt as of March 31, 2022 ranged fr om 1.0% to 4.0% a n d 0.4% to 3.4%, respectively.

Commitments and Contingencies	Commitments and Contingencies Guarantees As discussed in our 2021 Annual Report, we have guaranteed certain obligations of our subsidiaries relating principally to operating leases, uncommitted lines of credit and cash pooling arrangements. As of March 31, 2022 and December 31, 2021, the amount of parent company guarantees on lease obligation s was $639.4 and $667.5, respectively, the amount of parent company guarantees relating to uncommitted lines of credit was $310.8 and $306.5, respectively, and the amount of parent company guarantees related to daylight overdrafts, primarily utilized to manage intra-day overdrafts due to timing of transactions under cash pooling arrangements without resulting in incremental borrowings, was $103.3 and $104.4, respectively. In the event of non-payment by the applicable subsidiary of the obligations covered by a guaran tee, we would be obligated to pay the amounts covered by that guarantee. As of March 31, 2022, there wer e no material assets pledged as security for such parent company guarantees. Legal Matters We are involved in various legal proceedings, and subject to investigations, inspections, audits, inquiries and similar actions by governmental authorities, arising in the normal course of business. The types of allegations that arise in connection with such legal proceedings vary in nature, but can include claims related to contract, employment, tax and intellectual property matters. We evaluate all cases each reporting period and record liabilities for losses from legal proceedings when we determine that it is probable that the outcome in a legal proceeding will be unfavorable and the amount, or potential range, of loss can be reasonably estimated. In certain cases, we cannot reasonably estimate the potential loss because, for example, the litigation is in its early stages. While any outcome related to litigation or such governmental proceedings in which we are involved cannot be predicted with certainty, management believes that the outcome of these matters, individually and in the aggregate, will not have a material adverse effect on our financial condition, results of operations or cash flows.

Accounting Standards Update and Change in Accounting Principle [Abstract]
Recent Accounting Standards	Recent Accounting Standards Accounting pronouncements not listed below were assessed and determined to be not applicable or are expected to have minimal impact on our Consolidated Financial Statements. Derivatives and Hedging In March 2022, the Financial Accounting Standards Board (the "FASB") issued amended guidance on hedge accounting which allows nonprepayable financial assets to be included in a closed portfolio hedge using the portfolio layer method, allowing for more consistent accounting over prepayable and nonprepayable hedges. The new guidance also allows multiple hedged layers to be designated for a single closed portfolio further aligning hedge accounting with risk management strategies. This amended guidance is effective beginning January 1, 2023, with early adoption permitted. We are currently assessing the impact the adoption of the amended guidance will have on our Consolidated Financial Statements.

[1]	Contingent acquisition obligations includes deferred acquisition payments and unconditional obligations to purchase additional non-controlling equity shares of consolidated subsidiaries. Fair value measurement of the obligations is based upon actual and projected operating performance targets as specified in the related agreements. The increase in this balance of $0.1 from December 31, 2021 to March 31, 2022 is primarily due to the exercises of redeemable non-controlling interest and valuation adjustments, offset by payments related to our deferred acquisitions payments from prior-year acquisitions. The amounts payable within the next twelve months are classified in accrued liabilities; any amounts payable thereafter are classified in other non-current liabilities.
