Presentation of Financial Statements [Abstract]
Presentation of Financial Statements	Presentation of Financial Statements The terms “Omnicom,” the “Company,” “we,” “our” and “us” each refer to Omnicom Group Inc. and our subsidiaries, unless the context indicates otherwise. The accompanying unaudited consolidated financial statements were prepared in accordance with generally accepted accounting principles in the United States (“U.S. GAAP” or “GAAP”) for interim financial information and Article 10 of Regulation S-X of the Securities and Exchange Commission. Accordingly, certain information and footnote disclosure have been condensed or omitted. In our opinion, the accompanying unaudited consolidated financial statements reflect all adjustments, consisting of normal recurring accruals, considered necessary for a fair presentation, in all material respects, of the information contained herein. These unaudited consolidated financial statements should be read in conjunction with our Annual Report on Form 10-K for the year ended December 31, 2015 (“ 2015 10-K”). Results for the interim periods are not necessarily indicative of results that may be expected for the year. Certain reclassifications have been made to the prior year financial information to conform to the current year presentation. Effective January 1, 2016, selling, general and administrative expenses (“SG&A”) for the current and prior periods are reported as a separate line in the unaudited consolidated statements of income. Historically, we included SG&A expenses in salary and service costs and occupancy and other costs. In addition, we present cost of services in two distinct categories: salary and service costs, and occupancy and other costs. As a service business, salary and service costs make up the vast majority of our operating expenses and substantially all these costs comprise the essential components directly linked to the delivery of our services, such as employee compensation, including freelance labor, employee benefit costs, direct service costs, including the costs of third-party suppliers, and client-related travel costs. Occupancy and other costs consist of the indirect costs related to the delivery of our services, including office and equipment rent, other occupancy costs, technology costs, general office expenses and other expenses. SG&A expenses primarily consist of third-party marketing costs, professional fees and compensation and related benefit costs and occupancy and other costs of our corporate and executive offices, including group-wide finance and accounting, treasury, legal and governance, human resource oversight and similar costs.

New Accounting Standards

New Accounting Standards [Abstract]
New Accounting Standards	New Accounting Standards In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”) , which will replace all existing revenue recognition guidance under U.S. GAAP. On July 9, 2015, the FASB approved a one-year deferral of the effective date of ASU 2014-09 to all annual and interim periods beginning after December 15, 2017, with early application permitted only for annual and interim periods beginning after December 31, 2016. ASU 2014-09 provides for one of two methods of transition: retrospective application to each prior period presented or recognition of the cumulative effect of retrospective application of the new standard as of the beginning of the period of initial application. Presently, we are not yet in a position to conclude on the application date or the transition method we will choose. Based on our initial assessment, the impact of the application of the new standard will likely result in a change in the timing of our revenue recognition for performance incentives received from clients. Performance incentives are currently recognized in revenue when specific quantitative goals are achieved, or when our performance against qualitative goals is determined by the client. Under the new standard, we will be required to estimate the amount of the incentive that will be earned at the inception of the contract and recognize the incentive over the term of the contract. While performance incentives are not material to our revenue, this will result in an acceleration of revenue recognition for certain contract incentives compared to the current method. Additionally, in certain of our businesses we record revenue as a principal and include certain third-party pass-through and out-of-pocket costs, which are billed to clients in connection with our services, in revenue. In March 2016, the FASB issued further guidance on principal versus agent considerations. We are currently evaluating the impact of the principal versus agent guidance on our revenue and cost of service, however we do not expect the change, if any, to have a material effect on our results of operations. In February 2016, the FASB issued ASU 2016-02, Leases (“ASU 2016-02”), which eliminates the current tests for lease classification under U.S. GAAP and requires lessees to recognize the right-to-use assets and related lease liabilities on the balance sheet. ASU 2016-02 is effective for annual and interim periods beginning after December 15, 2018 and early application is permitted. ASU 2016-02 provides for a modified retrospective application for leases existing at, or entered into after, the earliest comparative period presented in the financial statements. We will apply ASU 2016-02 on January 1, 2019. While we are not yet in a position to assess the full impact of the application of the new standard, we expect that the impact of recording the lease liabilities and the corresponding right-to-use assets will have a significant impact on our total assets and liabilities with a minimal impact on our equity. In March 2016, the FASB issued ASU 2016-09, Compensation - Stock Compensation: Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”), which changes certain aspects of the accounting for share-based payments to employees. ASU 2016-09 is effective for annual and interim periods beginning after December 15, 2016 and early application is permitted. Certain changes will be applied prospectively and other changes will be applied using a modified retrospective approach with the recognition of the cumulative effect of the application of the new standard as of the beginning of the period of initial application. We will apply ASU 2016-09 on January 1, 2017. We do not expect that the application of the new standard will have a significant impact on income before income taxes. However, the new standard requires excess tax benefits or deficiencies related to share-based compensation to be recognized in income taxes as a tax benefit or expense upon vesting of restricted stock awards and the exercise of stock option awards. The excess tax benefit or expense will be calculated as the difference between the grant date price and the price of our common stock on the vesting or exercise date. As a result, the effect on tax expense is dependent on the price of our common stock and it is not possible to estimate with any accuracy the impact of the new standard on income tax expense. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), which changes the impairment model for most financial assets. The new model uses a forward-looking expected loss method, which will generally result in earlier recognition of allowances for losses. ASU 2016-13 is effective for annual and interim periods beginning after December 15, 2019 and early adoption is permitted for annual and interim periods beginning after December 15, 2018. We will apply ASU 2016-13 on January 1, 2020. However, we are not yet in a position to assess the impact of the application of the new standard on our results of operations or financial position. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows: Clarification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”), which eliminates the diversity in practice related to the classification of certain cash receipts and payments in the statement of cash flows, by adding or clarifying guidance on eight specific cash flow issues. ASU 2016-15 is effective for annual and interim reporting periods beginning after December 15, 2017 and early adoption is permitted. ASU 2016-15 provides for retrospective application for all periods presented. However, we are not yet in a position to assess the impact of the application of the new standard on our statement of cash flows.

Debt [Abstract]
Debt	Debt Credit Facilities As a source of short-term financing, we have a $2.5 billion revolving credit facility (“Credit Facility”) that expires July 31, 2021 and domestic and international uncommitted credit lines, and we can issue up to $2 billion of commercial paper. The uncommitted credit lines aggregated $1.1 billion and $1.2 billion at September 30, 2016 and December 31, 2015 , respectively. There were no outstanding commercial paper issuances or borrowings under the Credit Facility or the uncommitted credit lines at September 30, 2016 and December 31, 2015 . Available and unused credit lines at September 30, 2016 and December 31, 2015 were (in millions): 2016 2015 Credit Facility $ 2,500.0 $ 2,500.0 Uncommitted credit lines 1,141.3 1,157.7 Available and unused credit lines $ 3,641.3 $ 3,657.7 The Credit Facility contains financial covenants that require us to maintain a Leverage Ratio of consolidated indebtedness to consolidated EBITDA of no more than 3 times for the most recently ended 12-month period (EBITDA is defined as earnings before interest, taxes, depreciation and amortization) and an Interest Coverage Ratio of consolidated EBITDA to interest expense of at least 5 times for the most recently ended 12-month period. At September 30, 2016 we were in compliance with these covenants as our Leverage Ratio was 2.2 times and our Interest Coverage Ratio was 11.1 times. The Credit Facility does not limit our ability to declare or pay dividends or repurchase our common stock. Short-Term Debt Short-term debt at September 30, 2016 and December 31, 2015 of $25.0 million and $5.2 million , respectively, represents bank overdrafts and short-term borrowings of our international subsidiaries. Due to the short-term nature of this debt, carrying value approximates fair value. Long-Term Debt Long-term debt at September 30, 2016 and December 31, 2015 was (in millions): 2016 2015 5.9% Senior Notes due 2016 $ — $ 1,000.0 6.25% Senior Notes due 2019 500.0 500.0 4.45% Senior Notes due 2020 1,000.0 1,000.0 3.625% Senior Notes due 2022 1,250.0 1,250.0 3.65% Senior Notes due 2024 750.0 750.0 3.60% Senior Notes due 2026 1,400.0 — Other debt 0.2 0.3 4,900.2 4,500.3 Unamortized premium (discount) on senior notes, net 8.0 10.1 Debt issuance costs (25.2 ) (16.9 ) Adjustment to carrying value for interest rate swaps 124.5 72.1 5,007.5 4,565.6 Current portion (0.2 ) (1,001.4 ) Long-term debt $ 5,007.3 $ 3,564.2 On April 6, 2016, we issued $1.4 billion principal amount of 3.60% Senior Notes due April 15, 2026 (“2026 Notes”). The net proceeds received by us, after deducting the underwriting discount and offering expenses, were $1.387 billion . A portion of the net proceeds were used to retire the outstanding $1 billion 5.9% Senior Notes due 2016 (“2016 Notes”) at maturity on April 15, 2016. On March 28, 2016 , we settled the outstanding forward-starting interest rate swap, which was entered into in connection with the refinancing of the 2016 Notes, at a loss of $54.5 million , which was paid to the counterparties on April 6, 2016. Beginning in April 2016, the loss is being amortized in interest expense over the term of the 2026 Notes resulting in an effective interest rate on the 2026 Notes of approximately 4.1% . On January 19, 2016 , we settled the outstanding $1 billion interest rate swap on our 3.625% Senior Notes due 2022 (“2022 Notes”) and realized a gain of $54.2 million . The gain is being amortized in interest expense over the remaining term of the 2022 Notes. In connection with the outstanding $750 million interest rate swap on the 3.65% Senior Notes due 2024 (“2024 Notes”), at September 30, 2016 we recorded a receivable, which is included in other assets, of $28.2 million and at December 31, 2015 we recorded a liability, which was included in long-term liabilities of $10.0 million . The asset and liability represent the fair value of the swap that was substantially offset by the change in the carrying value of the 2024 Notes reflecting the change in fair value of the notes. Accordingly, any hedge ineffectiveness was not material to our results of operations. On April 6, 2016, in connection with the issuance of the 2026 Notes, we entered into a $500 million notional amount fixed-to-floating interest rate swap. The swap hedges the risk of changes in fair value of a portion of the notes attributable to changes in the benchmark LIBOR interest rate. We will receive fixed interest rate payments equal to the coupon interest rate on the notes and will pay a variable interest rate equal to three month LIBOR, plus a spread of 1.982% . The swap qualifies and is designated as a fair value hedge on the 2026 Notes. Gains and losses attributed to changes in the fair value of the swap are expected to substantially offset changes in the fair value of the notes attributed to changes in the benchmark interest rate. The net interest settlement is recorded in interest expense. At September 30, 2016 , we recorded a receivable, which was included in other assets, of $6.9 million . The asset represents the fair value of the swap that was substantially offset by the change in the fair value of the notes. As of September 30, 2016 , the total aggregate principal amount of our fixed rate senior notes was $4.9 billion and the total notional amount of the fixed-to-floating interest rate swaps was $1.25 billion .

Segment Reporting [Abstract]
Segment Reporting	Segment Reporting Our five branded agency networks operate in the advertising, marketing and corporate communications services industry, and are organized into agency networks, virtual client networks, regional reporting units and operating groups. Our networks, virtual client networks and agencies increasingly share clients and provide clients with integrated services. The main economic components of each agency are employee compensation and related costs and direct service costs and office and general costs which include rent and occupancy costs, technology costs and other overhead expenses. Therefore, given these similarities, we aggregate our operating segments, which are our five agency networks, into one reporting segment. The agency networks' regional reporting units comprise three principal regions: the Americas, EMEA and Asia Pacific.
