| 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 preparation of financial statements in conformity with U.S. GAAP requires us to make judgments, assumptions and estimates that affect the amounts reported and disclosed. 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 2016 Annual Report on Form 10-K. 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. |

| Debt and Credit Arrangements | Debt and Credit Arrangements Long-Term Debt A summary of the carrying amounts and fair values of our long-term debt is listed below.
Credit Agreements We maintain a committed corporate credit facility, 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 October 2020, 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 $1,000.0, or the equivalent in other specified 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 on letters of credit of $200.0, or the equivalent in other specified currencies. Our obligations under the Credit Agreement are unsecured. As of September 30, 2017, there were no borrowings under the Credit Agreement; however, we had $8.4 of letters of credit under the Credit Agreement, which reduced our total availability to $991.6. We were in compliance with all of our covenants in the Credit Agreement as of September 30, 2017. On October 25, 2017, we amended and restated our Credit Agreement. See Note 14 for further discussion. We also have uncommitted lines of credit with various banks which permit borrowings at variable interest rates and which 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 international operations. As of September 30, 2017, the Company had uncommitted lines of credit in an aggregate amount of $916.8, under which we had outstanding borrowings of $152.5 classified as short-term borrowings on our Consolidated Balance Sheet. The average amount outstanding during the third quarter of 2017 was $124.7, with a weighted-average interest rate of approximately 3.1%. Commercial Paper In June 2017, the Company established a commercial paper program under which the Company was authorized to issue unsecured commercial paper up to a maximum aggregate amount outstanding at any time of $1,000.0. Borrowings under the program are supported by the Credit Agreement described above. Proceeds of the commercial paper will be 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 September 30, 2017, the Company had outstanding commercial paper of $359.3 classified as short-term borrowings on our Consolidated Balance Sheet. The average amount outstanding under the program during the third quarter of 2017 was $488.2, with a weighted-average interest rate of 1.4% and a weighted-average maturity of fourteen days. On October 25, 2017, the Company increased the maximum aggregate amount outstanding at any time under our commercial paper program from $1,000.0 to $1,500.0. See Note 14 for further discussion. |

| Acquisitions | Acquisitions We continue to evaluate strategic opportunities to expand our industry expertise, strengthen our position in high-growth and key strategic geographical markets and industry sectors, advance our technological capabilities and improve our operational efficiency through both acquisitions and increased ownership interests in current investments. Our acquisitions typically provide for an initial payment at the time of closing and additional contingent purchase price payments based on the future performance of the acquired entity. We have entered into agreements that may require us to purchase additional equity interests in certain consolidated and unconsolidated subsidiaries. The amounts at which we record these transactions in our financial statements are based on estimates of the future financial performance of the acquired entity, the timing of the exercise of these rights, foreign currency exchange rates and other factors. During the first nine months of 2017, we completed seven acquisitions, including a strategic communications agency based in the U.K., an independent creative agency based in the U.K., a retail branding and design firm based in the U.S., a content creation and marketing agency based in the Netherlands, an independent media agency and digital consultancy based in Finland, and an integrated marketing communications agency based in Canada. All seven of our acquisitions were included in the Integrated Agency Networks ("IAN") operating segment. During the first nine months of 2017, we recorded approximately $48.1 of goodwill and intangible assets related to our acquisitions. During the first nine months of 2016, we completed nine acquisitions, including a product and service design consultancy based in the U.S., an integrated healthcare marketing communications agency based in the U.S., a content creation and digital agency with offices in the U.S. and the U.K., a mobile consultancy and application development agency based in the U.K., a branded content production agency specializing in sports and entertainment based in Australia, a full-service public relations and digital agency based in China, a search engine optimization and digital content marketing agency based in the U.K., a mobile focused digital agency based in the U.K. and a business consultancy services agency based in Australia. Of our nine acquisitions, three were included in the IAN operating segment, and six were included in the Constituency Management Group ("CMG") operating segment. During the first nine months of 2016, we recorded approximately $147.9 of goodwill and intangible assets related to our acquisitions, primarily in CMG. The results of operations of our acquired companies were included in our consolidated results from the closing date of each acquisition. Details of cash paid for current and prior years' acquisitions are listed below.
Many of our acquisitions include provisions under which the noncontrolling equity owners may require us to purchase additional interests in a subsidiary at their discretion. Redeemable noncontrolling interests are adjusted quarterly to their estimated redemption value, but not less than their initial fair value. Any adjustments to the redemption value impact retained earnings, except for foreign currency translation adjustments. The following table presents changes in our redeemable noncontrolling interests.

We may effect such repurchases through open market purchases, trading plans established in accordance with SEC rules, derivative transactions or other means.

| Income Tax Disclosure [Abstract] | |
| Income Taxes | Income Taxes For the three and nine months ended September 30, 2017, our effective income tax rates of 22.1% and 30.7%, respectively, were positively impacted by a benefit of $31.2 related to foreign tax credits from distributions of unremitted earnings, partially offset by losses in certain foreign jurisdictions where we receive no tax benefit due to 100% valuation allowances and by losses on sales of businesses, and the classification of certain assets as held for sale, for which we did not receive a full tax benefit. For the nine months ended September 30, 2017, our effective income tax rate 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. We have various tax years under examination by tax authorities in various countries, and in various states, such as New York, 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 $25.0 and $35.0 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 2007 or non-U.S. income tax audits for years prior to 2006. |

| 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:
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 nine months ended September 30, 2017. The following tables present information about our financial instruments measured at fair value on a recurring basis as of September 30, 2017 and December 31, 2016, and indicate the fair value hierarchy of the valuation techniques utilized to determine such fair value.
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 September 30, 2017 and December 31, 2016, and indicates the fair value hierarchy of the valuation techniques utilized to determine such fair value.
Our long-term debt is comprised of senior notes and other notes payable. The fair value of our senior notes traded over-the-counter is based on quoted prices for such securities, but for which fair value can also be derived from inputs that are readily observable. Therefore, these senior notes are classified as Level 2 within the fair value hierarchy. Our other notes payable are not actively traded, and their fair value is not solely derived from readily observable inputs. Thus, the fair value of our other notes payable is determined based on proprietary valuation methods and therefore are classified as Level 3 within the fair value hierarchy. See Note 2 for further information on our long-term debt. Non-financial Assets and Liabilities that are Measured at Fair Value on a Recurring Basis Certain non-financial assets and liabilities are measured at fair value on a recurring basis, primarily accrued restructuring charges. 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, 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. |

| Commitments and Contingencies Disclosure [Abstract] | |
| Commitments and Contingencies | Commitments and Contingencies 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 may 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. As previously disclosed, on April 10, 2015, a federal judge in Brazil authorized the search of the records of an agency's offices in São Paulo and Brasilia, in connection with an ongoing investigation by Brazilian authorities involving payments potentially connected to local government contracts. The Company had previously investigated the matter and taken a number of remedial and disciplinary actions. The Company is in the process of concluding a settlement related to these matters with government agencies. The Company confirmed that one of its standalone domestic agencies has been contacted by the Department of Justice Antitrust Division for documents regarding video production practices and is cooperating with the government. Guarantees As discussed in our 2016 Annual Report on Form 10-K, we have guaranteed certain obligations of our subsidiaries relating principally to operating leases and uncommitted lines of credit of certain subsidiaries. The amount of parent company guarantees on lease obligations was $827.8 and $857.3 as of September 30, 2017 and December 31, 2016, respectively, and the amount of parent company guarantees primarily relating to uncommitted lines of credit was $413.8 and $395.6 as of September 30, 2017 and December 31, 2016, respectively. |

Recent Accounting Standards (Notes) |

| New Accounting Pronouncements and Changes in Accounting Principles [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 August 2017, the Financial Accounting Standards Board (the "FASB") issued amended guidance on hedge accounting which expands an entity’s ability to hedge non-financial and financial risk components and aligns the recognition and presentation of the effects of the hedging instrument and the hedged item in the financial statements. The new guidance also eliminates the requirement to separately measure and report hedge ineffectiveness. This amended guidance is effective beginning January 1, 2019, with early adoption permitted. We are currently assessing the impact the adoption of the amended guidance will have on our Consolidated Financial Statements. Pensions In March 2017, the FASB issued amended guidance which requires presentation of all net periodic pension and postretirement benefit costs, other than service costs, in non-operating expenses in the Consolidated Statement of Operations. We have early adopted this amended guidance retrospectively as of the quarter ended March 31, 2017 using the practical expedient, which permits the use of amounts disclosed in our Employee Benefits note for prior comparative periods as the estimation basis for applying the retrospective presentation requirements. This resulted in the reclassification of a portion of postretirement costs from "Salaries and related expenses" to "Other (expense) income, net" in the amount of $4.8 and $0.8 for the three months ended September 30, 2017 and 2016, respectively, and $6.4 and $2.4 for the nine months ended September 30, 2017 and 2016, respectively. Restricted Cash In November 2016, the FASB issued amended guidance which requires that the Consolidated Statement of Cash Flows present the change during the period in the total cash, cash equivalents and amounts generally described as restricted cash or restricted cash equivalents. We have early adopted this amended guidance retrospectively as of the quarter ended March 31, 2017. The Consolidated Statements of Cash Flows for the nine months ended September 30, 2017 and 2016 now include restricted cash balances of $2.5 and $3.2, respectively, in the beginning-of-period totals and $3.1 and $3.9, respectively, in the end-of-period totals. Financial Instrument Credit Losses In June 2016, the 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. This amended guidance is effective beginning January 1, 2020, with early adoption permitted as early as January 1, 2019. We are currently assessing the impact the adoption of the amended guidance will have on our Consolidated Financial Statements. Leases In February 2016, the FASB issued amended guidance on lease accounting which requires an entity to recognize a right-of-use asset and a corresponding lease liability on its balance sheet for virtually all of its leases with a term of more than 12 months, including those classified as operating leases. Both the asset and liability will initially be measured at the present value of the future minimum lease payments, with the asset being subject to adjustments such as initial direct costs. Consistent with current U.S. GAAP, the presentation of expenses and cash flows will depend primarily on the classification of the lease as either a finance or an operating lease. The new standard also requires additional quantitative and qualitative disclosures regarding the amount, timing and uncertainty of cash flows arising from leases in order to provide additional information about the nature of an organization’s leasing activities. This amended guidance, which will be effective beginning January 1, 2019, requires modified retrospective application, with early adoption permitted. We expect the adoption of this amended guidance to have a significant impact on our Consolidated Balance Sheets but not on our Consolidated Statements of Operations. Fair Value Measurements In January 2016, the FASB issued amended guidance which updates the fair value presentation requirements for certain financial instruments. Equity investments with readily determinable fair values, other than those accounted for using the equity method of accounting, will be measured at fair value with changes recorded through current earnings rather than other comprehensive income. This amended guidance will be effective for us beginning January 1, 2018, and is required to be adopted prospectively with a cumulative-effect adjustment recorded on our Consolidated Balance Sheets, if applicable. We do not expect the adoption of this amended guidance to have a significant impact on our Consolidated Financial Statements. Revenue Recognition In May 2014, the FASB issued amended guidance on revenue recognition which requires an entity to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods and services. We expect to adopt the standard, which is effective January 1, 2018, using the full retrospective method. The standard impacts the timing of revenue recognition between quarters, primarily as a result of estimating variable consideration. We have determined that the standard will result in an increase in the number of performance obligations within certain of our contractual arrangements. The standard will also result in an increase in third party costs being included in revenue, primarily in connection with our events businesses, which will have no impact on operating income or net income. Additionally, we continue to evaluate the disclosures that may be required. |

| Subsequent Events [Text Block] | Note 14: Subsequent Events On October 25, 2017, we amended and restated our Credit Agreement, which was most recently amended and restated on October 20, 2015. The amendment increases the revolving commitments under the Credit Agreement from $1,000.0 to $1,500.0 and extends the Credit Agreement's expiration to October 25, 2022. 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. The cost structure, financial covenants and the ability to increase the commitments under the Credit Agreement from time to time by an additional amount of up to $250.0 remain unchanged by the amendment. On October 25, 2017, the Company increased the maximum aggregate amount outstanding at any time under our commercial paper program from $1,000.0 to $1,500.0. Borrowings under the program continue to be supported by the Credit Agreement, and the proceeds of which will be used for working capital and general corporate purposes, including the repayment of maturing indebtedness and other short-term liquidity needs. |
