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 COVID-19 pandemic have negatively impacted and will likely continue to negatively 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 the allowance for doubtful accounts. 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, 2019 (the “ 2019 Annual Report”). Cost of services is comprised of the expenses of our revenue-producing reportable segments, Integrated Agency Networks (“IAN”) and Constituency Management Group (“CMG”), including salaries and related expenses, office and other direct expenses and billable expenses, and includes an allocation of the centrally managed expenses of 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 of our Corporate and other group, 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 the current period relate to the Company's implementation of restructuring actions 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 impairments costs. Segment information for the prior period has been recast to conform to the current-period presentation. 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 and immaterial revisions 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 $696.0 of unsatisfied performance obligations as of June 30, 2020 , which will be recognized as services are performed over the remaining contractual terms through 2026.

Refer to Note 12 for details. Debt Transactions 4.75% Senior Notes Due 2030 On March 30, 2020, we issued a total of $650.0 in aggregate principal amount of 4.75% senior unsecured notes (the “ 4.75% Senior Notes”) due March 30, 2030. Upon issuance, the 4.75% Senior Notes were reflected in our unaudited Consolidated Balance Sheets at $640.0 , net of discount of $3.8 and net of capitalized debt issuance costs, including commissions and offering expenses of $6.2 , both of which will be amortized in interest expense through the maturity date using the effective method. Interest is payable semi-annually in arrears on March 30th and September 30th of each year, commencing on September 30, 2020. Consistent with our other outstanding debt securities, the newly issued 4.75% Senior Notes include covenants that, among other things, limit our liens and the liens of certain of our consolidated subsidiaries, but do not require us to maintain any financial ratios or specified levels of net worth or liquidity. We may redeem the 4.75% Senior Notes at any time in whole, or from time to time in part, in accordance with the provisions of the indenture, including the supplemental indenture, under which the 4.75% Senior Notes were issued. Additionally, upon the occurrence of a change of control repurchase event with respect to the 4.75% Senior Notes, each holder of the 4.75% Senior Notes has the right to require the Company to purchase that holder’s 4.75% Senior Notes at a price equal to 101% of the principal amount thereof, plus accrued and unpaid interest, unless the Company has exercised its option to redeem all the 4.75% Senior Notes. Credit Arrangements 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. The Credit Agreement is a revolving facility, expiring in November 2024 , 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. As of June 30, 2020 , there were no borrowings under the Credit Agreement; however, we had $8.3 of letters of credit under the Credit Agreement, which reduced our total availability to $1,491.7 . We were in compliance with all of our covenants in the Credit Agreement as of June 30, 2020 . 364-Day Credit Facility On March 27, 2020, we entered into an agreement for a 364-day revolving credit facility (the "364-Day Credit Facility") that matures on March 26, 2021. The 364-Day Credit Facility is a revolving facility, under which amounts borrowed by us may be repaid and reborrowed, subject to an aggregate lending limit of $500.0 . The cost structure of the 364-Day Credit Agreement is based on the Company’s current credit ratings. The applicable margin for Base Rate Advances (as defined in the 364-Day Credit Facility) is 0.250% , the applicable margin for Eurodollar Rate Advances (as defined in the 364-Day Credit Facility) is 1.250% , and the facility fee payable on a lender’s revolving commitment is 0.250% . In addition, the 364-Day Credit Facility includes covenants that, among other things, (i) limit our liens and the liens of our consolidated subsidiaries, and (ii) limit subsidiary debt. The 364-Day Credit Facility also contains a financial covenant that requires us to maintain, on a consolidated basis as of the end of each fiscal quarter, a leverage ratio for the four quarters then ended. The leverage ratio and other covenants set forth in the 364-Day Credit Facility are identical to the covenants contained in the Company’s existing Credit Agreement, which remains in full effect. As of June 30, 2020 , there were no borrowings under the 364-Day Credit Facility, and we were in compliance with all of our covenants in the 364-Day Credit Facility. 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 June 30, 2020 , the Company had uncommitted lines of credit in an aggregate amount of $928.4 , under which we had outstanding borrowings of $51.9 classified as short-term borrowings on our Consolidated Balance Sheet. The average amount outstanding during the second quarter of 2020 was $76.4 , with a weighted-average interest rate of approximately 3.7% . 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. As of June 30, 2020 , there was no commercial paper outstanding. The average amount outstanding under the program during the second quarter of 2020 was $365.7 , with a weighted-average interest rate of approximately 1.3% and a weighted-average maturity of 12 days.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes For the three months ended June 30, 2020 , our income tax provision was negatively impacted by losses in certain foreign jurisdictions where we received no tax benefit due to 100% valuation allowances, by net losses on sales of businesses and the classification of certain assets as held for sale for which we received no tax benefit and by tax expense associated with the change to our assertion regarding the permanent reinvestment of undistributed earnings attributable to certain foreign subsidiaries. For the six months ended June 30, 2020 , our income tax provision was negatively impacted by the same factors noted for the three months ended June 30, 2020 in addition to net losses on sales of businesses and the classification of certain assets as held for sale, for which we received minimal tax benefit. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) was enacted and signed into law. The CARES Act includes several provisions for corporations including increasing the amount of deductible interest, allowing companies to carryback certain net operating losses (“NOLs”) and increasing the amount of NOLs that corporations can use to offset income. The CARES Act did not materially affect our quarter or year-to-date income tax provision, deferred tax assets and liabilities, or related taxes payable. We are currently assessing the future implications of these provisions within the CARES Act on our Consolidated Financial Statements, but do not expect the impact to be material. In the second quarter of 2020, in response to changes in non-US tax law, a decision was made to change our indefinite reinvestment assertion on a $110.0 of undistributed foreign earnings of specific subsidiaries. We recorded $10.0 of income tax costs associated with this change to our assertion. 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 $180.0 and $190.0 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 2012, with the exception of 2009. 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 2009.

Most of these actions are based on our recent experience and learning in the COVID-19 pandemic and a resulting review of our operations, which continues, to address certain operating expenses such as occupancy expense and salaries and related expenses. Net restructuring charges were comprised of $68.8 at IAN and $36.7 at CMG for the three and six months ended June 30, 2020, which include non-cash lease impairment costs of $35.8 at IAN and $26.8 at CMG. Restructuring actions under the 2020 Plan were identified and initiated during the second quarter of 2020, with additional actions expected during the third and fourth quarters and all actions to be substantially complete by the end of the fourth quarter of 2020. During the first half of 2020, severance and termination costs related to a planned reduction in workforce of 694 employees. The employee groups affected include executive, regional and account management as well as administrative, creative and media production personnel. Lease impairment costs, which relate to the office spaces that were vacated as part of the 2020 Plan, included impairments of operating lease right-of-use assets and associated leasehold improvements, furniture and asset retirement obligations. 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. A summary of the restructuring activities related to the 2020 Plan is as follows: 2020 Plan Restructuring Expense Non-Cash Items Cash Payments Liability at June 30, 2020 Severance and termination costs $ 44.6 $ 0.7 $ 10.1 $ 33.8 Lease impairment costs 65.7 65.7 0.0 0.0 Other 2.3 1.2 1.1 0.0 Total $ 112.6 $ 67.6 $ 11.2 $ 33.8 2019 Restructuring Plan In the first quarter of 2019, the Company implemented a cost initiative (the “2019 Plan”) to better align our cost structure with our revenue primarily related to specific client losses occurring in 2018. All restructuring actions were identified and initiated by the end of the first quarter of 2019, with all actions substantially completed by the end of the second quarter of 2019, and there have not been any restructuring adjustments.

We also have numerous funded and unfunded plans outside the U.S. The Interpublic Limited Pension Plan in the U.K. is a defined benefit plan and is our most material foreign pension plan in terms of the benefit obligation and plan assets. Some of our domestic and foreign subsidiaries provide postretirement health benefits and life insurance to eligible employees and, in certain cases, their dependents. The domestic postretirement benefit plan is our most material postretirement benefit plan in terms of the benefit obligation.

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 six months ended June 30, 2020 . The following tables present information about our financial instruments measured at fair value on a recurring basis as of June 30, 2020 and December 31, 2019 , and indicate the fair value hierarchy of the valuation techniques utilized to determine such fair value. June 30, 2020 Balance Sheet Classification Level 1 Level 2 Level 3 Total Assets Cash equivalents $ 690.2 $ 0.0 $ 0.0 $ 690.2 Cash and cash equivalents Liabilities Contingent acquisition obligations 1 $ 0.0 $ 0.0 $ 96.5 $ 96.5 Accrued liabilities and Other non-current liabilities December 31, 2019 Balance Sheet Classification Level 1 Level 2 Level 3 Total Assets Cash equivalents $ 786.0 $ 0.0 $ 0.0 $ 786.0 Cash and cash equivalents Liabilities Contingent acquisition obligations 1 $ 0.0 $ 0.0 $ 114.1 $ 114.1 Accrued liabilities and Other non-current liabilities 1 Contingent acquisition obligations includes deferred acquisition payments and unconditional obligations to purchase additional noncontrolling 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 decrease in this balance of $17.6 from December 31, 2019 to June 30, 2020 is primarily due to acquisition payments, partially offset by valuation adjustments, an increase in deferred acquisition payments and exercises of put options. 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 June 30, 2020 and December 31, 2019 , and indicates the fair value hierarchy of the valuation techniques utilized to determine such fair value. June 30, 2020 December 31, 2019 Level 1 Level 2 Level 3 Total Level 1 Level 2 Level 3 Total Total long-term debt $ 0.0 $ 4,254.0 $ 45.4 $ 4,299.4 $ 0.0 $ 3,520.0 $ 45.5 $ 3,565.5 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 June 30, 2020 ranged from 2.0% to 5.0% and 0.5% to 3.5% , respectively. Non-financial Assets and Liabilities that are Measured at Fair Value on a Nonrecurring Basis Certain non-financial assets and liabilities are measured at fair value on a nonrecurring basis, primarily goodwill (Level 3), intangible assets, and property and equipment. Accordingly, these assets are not measured and adjusted to fair value on an ongoing basis but are subject to periodic evaluations for potential impairment. During the second quarter of 2020, recent economic developments related to the COVID-19 pandemic contributed to declines in our most recent forecasted financial results. We evaluated our reporting units including the impact of these declines, restructuring actions taken in the second quarter of 2020 and other reporting unit specific factors, and concluded that this constituted a goodwill triggering event for one reporting unit, requiring us to evaluate its goodwill for impairment. Based on the results of a quantitative interim impairment test, we concluded that the reporting unit’s goodwill was not impaired as of June 30, 2020, because the fair value of the reporting unit was in excess of its carrying value.

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. Financial Instrument Credit Losses In June 2016, the Financial Accounting Standards Board ("FASB") issued amended guidance on the accounting for credit losses on certain types of financial instruments, including trade receivables. The new model uses a forward-looking expected loss method, as opposed to the incurred loss method in current U.S. GAAP, which will generally result in earlier recognition of allowances for losses. We adopted this standard using the modified retrospective approach with an effective date of January 1, 2020. The adoption of this amended guidance did not have a material impact on our Consolidated Financial Statements. Fair Value Measurement Disclosures In August 2018, the FASB issued amended disclosure requirements for fair value measurements by removing, modifying and adding certain disclosures. This amended guidance was effective beginning January 1, 2020. The adoption of this guidance did not have a material impact on our Consolidated Financial Statements. Income Taxes In December 2019, the FASB issued amended guidance to simplify the accounting for income taxes by removing certain exceptions and amending certain sections of existing guidance under ASC 740. This amended guidance is effective January 1, 2021 with early adoption permitted as early as January 1, 2020. We are currently assessing the impact the adoption of the amended guidance will have on our Consolidated Financial Statements.

Subsequent Events [Text Block]	Subsequent Events Credit Agreement Amendments On July 28, 2020, we entered into Amendment No. 1 to the Credit Agreement and Amendment No. 1 to the 364-Day Credit Facility (together, the “Amendments”). The Amendments increased the maximum leverage ratio covenant to 4.25x in the case of the 364-Day Credit Facility and, in the case of the Credit Agreement, to (i) 4.25x through the quarter ended June 30, 2021, and (ii) 3.50x thereafter. Amendment No. 1 to the Credit Agreement also increased the Applicable Margin (as defined in the Credit Agreement) for any borrowings we make under the Credit Agreement if our long-term public debt ratings are BB+/Ba1 or below at the time of borrowing. We have the option to terminate Amendment No. 1 to the Credit Agreement at any time, provided that at the time we deliver a termination notice the leverage ratio as of the end of the most recently ended fiscal quarter did not exceed 3.50x. The Credit Agreement reverts to its original terms on June 30, 2021, or following any such early termination, whichever is earlier. We paid amendment fees of $2.0 in connection with the Amendments. Tax Examination Settlement On July 29, 2020, the Internal Revenue Service notified the Company that the U.S. Federal income tax examination of years 2006 through 2016 has been finalized and effectively settled. As a result, we expect to recognize an income tax benefit of approximately $135.0 in the third quarter of 2020.

[1]	Contingent acquisition obligations includes deferred acquisition payments and unconditional obligations to purchase additional noncontrolling 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 decrease in this balance of $17.6 from December 31, 2019 to June 30, 2020 is primarily due to acquisition payments, partially offset by valuation adjustments, an increase in deferred acquisition payments and exercises of put options. The amounts payable within the next twelve months are classified in accrued liabilities; any amounts payable thereafter are classified in other non-current liabilities.
