Description of Business and Summary of Significant Accounting Policies [Abstract]
Description Of Business And Summary Of Significant Accounting Policies	Description of Business and Summary of Significant Accounting Policies Description of Business CDW Corporation (“Parent”) is a Fortune 500 company with multi-national capabilities and a leading provider of integrated information technology (“IT”) solutions to small, medium and large business, government, education and healthcare customers in the United States, Canada and the United Kingdom. The Company's offerings range from discrete hardware and software products to integrated IT solutions such as mobility, security, data center optimization, cloud computing, virtualization and collaboration. Throughout this report, the terms the “Company” and “CDW” refer to Parent and its 100% owned subsidiaries. Parent has two 100% owned subsidiaries, CDW LLC and CDW Finance Corporation. CDW LLC is an Illinois limited liability company that, together with its 100% owned subsidiaries, holds all material assets and conducts all business activities and operations of the Company. CDW Finance Corporation is a Delaware corporation formed for the sole purpose of acting as co-issuer of certain debt obligations and does not hold any material assets or engage in any business activities or operations. On August 1, 2015, the Company completed the acquisition of Kelway TopCo Limited (“Kelway”) by purchasing the remaining 65% of its outstanding common stock which increased the Company’s ownership interest from 35% to 100% , and provided the Company control. On April 4, 2016, Kelway was rebranded CDW UK. Throughout this report, the term "CDW UK" refers to Kelway. For further details regarding the acquisition, see Note 3 (Acquisition). Basis of Presentation The unaudited interim Consolidated Financial Statements as of March 31, 2016 and for the three months ended March 31, 2016 and 2015 (the “Consolidated Financial Statements”) have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) for interim financial statements. Accordingly, certain information and footnote disclosures normally included in Consolidated Financial Statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. These Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2015 (the “December 31, 2015 Consolidated Financial Statements”). The significant accounting policies used in preparing these Consolidated Financial Statements were applied on a basis consistent with those reflected in the December 31, 2015 Consolidated Financial Statements. In the opinion of management, the Consolidated Financial Statements contain all adjustments (consisting of a normal, recurring nature) necessary to present fairly the Company's financial position, results of operations, comprehensive income, cash flows and changes in stockholders' equity as of the dates and for the periods indicated. The unaudited results of operations for such interim periods reported are not necessarily indicative of results for the full year. Principles of Consolidation The accompanying Consolidated Financial Statements include the accounts of Parent and its 100% owned subsidiaries. All intercompany transactions and accounts are eliminated in consolidation. Use of Estimates The preparation of the Consolidated Financial Statements in accordance with GAAP requires management to make use of certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the Consolidated Financial Statements and the reported amounts of revenue and expenses during the reported periods. The Company bases its estimates on historical experience and on various other assumptions that management believes are reasonable under the circumstances, the results of which form the basis for making judgments about carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from those estimates. The notes to the Consolidated Financial Statements contained in the December 31, 2015 Consolidated Financial Statements include an additional discussion of the significant accounting policies and estimates used in the preparation of the Company's Consolidated Financial Statements. There have been no material changes to the Company's significant accounting policies and estimates during the three months ended March 31, 2016 .

Recent Accounting Pronouncements [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements Improvements to Employee Share-Based Payment Accounting In March 2016, the Financial Accounting Standards Board (the "FASB") issued Accounting Standards Update ("ASU") 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, requiring the recognition of the income tax effects of stock awards in the income statement when the awards are settled and allowing the Company to repurchase more of an employee's shares than allowed under current guidance, without triggering liability accounting. This ASU also addresses simplifications related to statement of cash flows classification and accounting for forfeitures. This ASU is effective for the Company beginning in the first quarter of 2017 and allows for early adoption. The Company is currently evaluating the method of adoption and the impact this ASU will have on its Consolidated Financial Statements. Accounting for Leases In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), requiring lessees to recognize assets and liabilities on the balance sheet for the rights and obligations created by long-term leases and to disclose additional quantitative and qualitative information about leasing arrangements. This ASU is effective for the Company beginning in the first quarter of 2019 and allows for early adoption. The Company is currently evaluating the method of adoption and the impact this ASU will have on its Consolidated Financial Statements. Balance Sheet Classification of Deferred Taxes In November 2015, the FASB issued ASU 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes, simplifying the presentation of deferred income taxes by requiring all deferred taxes to be presented as noncurrent in the balance sheet. In the first quarter of 2016, the Company elected to early adopt ASU 2015-17 on a prospective basis. The adoption of this standard did not have a material impact on the Company's Consolidated Financial Statements. Simplifying the Measurement of Inventory In July 2015, the FASB issued ASU 2015-11, Inventory (Topic 330): Simplifying the Measurement of Inventory, amending the subsequent measurement of inventory by requiring inventory to be measured at the lower of cost and net realizable value instead of the lower of cost or market value. This ASU is effective for the Company beginning in the first quarter of 2017, allows for early adoption and must be applied prospectively after the date of adoption. This ASU is not expected to have a material impact on the Company’s Consolidated Financial Statements. Revenue Recognition In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606), replacing most existing revenue recognition guidance under GAAP and eliminating industry specific guidance. The core principle of the new guidance is that an entity should recognize revenue for the transfer of goods and services equal to an amount it expects to be entitled to receive for those goods and services. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date, deferring the effective date by one year. In March 2016, the FASB issued ASU 2016-08, Revenue from Contracts with Customers (Topic 606): Principal versus Agent Considerations (Reporting Gross versus Net), clarifying the principal versus agent guidance in the new revenue recognition standard, by revising the indicators to focus on evidence that the company is a principal. This ASU is effective for the Company beginning in the first quarter of 2018, allows for early adoption in the first quarter of 2017 and may be applied using either a full retrospective approach or a modified retrospective approach. The Company is currently evaluating the method of adoption and the impact this ASU will have on its Consolidated Financial Statements.

Business Combinations [Abstract]
Acquisition	Acquisition On August 1, 2015 , the Company completed the acquisition of CDW UK by purchasing the remaining 65% of its outstanding common stock which increased the Company's ownership interest from 35% to 100% , and provided the Company control. A summary of the total consideration transferred is as follows: (in millions) Acquisition-Date Fair Value Cash $ 291.6 Fair value of CDW common stock (1) 33.2 Fair value of previously held equity investment on the date of acquisition (2) 174.9 Total consideration $ 499.7 (1) The Company issued 2 million shares of CDW common stock. The fair value of the common stock was based on the closing market price on July 31, 2015 , adjusted for the lack of marketability as the shares of CDW common stock issued to the sellers are subject to a three -year lock up restriction from August 1, 2015 . One of the sellers granted 1 million stock options to certain CDW UK coworkers over his shares of CDW common stock received in the transaction. The fair value of these stock options was $22 million , which has been accounted for as post-combination stock-based compensation and is being amortized over the weighted­-average requisite service period of 3.2 years. Compensation expense for these options is included in Selling and administrative expenses in the Consolidated Statements of Operations. (2) As a result of the Company obtaining control over CDW UK, the Company’s previously held 35% equity investment was remeasured to fair value, resulting in a gain of $98 million included in Gain on remeasurement of equity investment in the Consolidated Statements of Operations. The fair value of the previously held equity investment was determined by management with the assistance of a third party valuation firm, based on information available as of the acquisition date. The recognized amounts of identifiable assets acquired and liabilities assumed, translated using the foreign currency exchange rates on the date of acquisition, are as follows: (in millions) Acquisition-Date Fair Value (1) Cash $ 27.8 Accounts receivable 135.7 Merchandise inventory 27.1 Property and equipment, net 11.4 Identified intangible assets (2) 289.8 Other assets 53.6 Total assets acquired 545.4 Accounts payable—trade (86.1 ) Deferred revenue (57.2 ) Other liabilities (41.5 ) Deferred tax liabilities (55.1 ) Debt (111.5 ) Total liabilities assumed (351.4 ) Total identifiable net assets 194.0 Goodwill 305.7 Total purchase price $ 499.7 (1) The fair values assigned to the tangible and intangible assets acquired and liabilities assumed were based on management’s estimates and assumptions, as well as other information compiled by management, including valuations that utilize customary valuation procedures and techniques. These fair values are subject to change within the measurement period. (2) Details of the identified intangible assets are as follows: (in millions) Acquisition-Date Fair Value Weighted-Average Amortization Period (in years) Customer relationships $ 260.8 13 Customer contracts 25.9 3 Developed technology 1.7 2 Trade name 1.4 1 Total identified intangible assets $ 289.8 Goodwill in the amount of $306 million was recognized in the acquisition of CDW UK and is attributable to the business from new customers and the value of the acquired assembled workforce. The goodwill was allocated to the CDW UK operating segment which is included with CDW Canada in an all other category (“Other”). The full amount of goodwill recognized is not deductible for income tax purposes in the United Kingdom. The unaudited pro forma Consolidated Statements of Operations in the table below summarizes the combined results of operations of the Company and CDW UK, as if the acquisition had been completed on January 1, 2015, and gives effect to pro forma events that are factually supportable and directly attributable to the transaction. The unaudited pro forma results reflect adjustments for equity-based compensation, acquisition and integration costs, incremental intangible asset amortization based on the fair values of each identifiable intangible asset, which are subject to change within the measurement period, pre-acquisition equity earnings, the gain on the remeasurement of the Company’s previously held 35% equity method investment, elimination of pre-acquisition intercompany sales transactions and the impacts of certain other pre-acquisition transactions. Pro forma adjustments were tax-effected at the statutory rates within the applicable jurisdictions. This unaudited pro forma information is presented for informational purposes only and may not be indicative of the historical results of operations that would have been obtained if the acquisition had taken place on January 1, 2015, nor the results that may be obtained in the future. This unaudited pro forma information does not reflect future synergies, integration costs, or other such costs or savings. The unaudited pro forma Consolidated Statements of Operations for the three months ended March 31, 2015 is as follows: Net sales $ 2,972.7 Net income 56.1 The unaudited pro forma information above reflects the following adjustments: (1) Excludes acquisition and integration costs directly related to the transaction. (2) Includes additional amortization expense related to the fair value of acquired intangibles. (3) Excludes the Company's share of net income/loss from its previously held 35% equity investment prior to the completion of the acquisition. (4) Excludes non-cash equity-based compensation related to certain equity awards granted by one of the sellers to CDW UK coworkers in July 2015 prior to the completion of the acquisition. (5) Includes additional non-cash equity-based compensation related to equity awards granted to CDW UK coworkers after the completion of the acquisition.

As of March 31, 2016 , the Company had no outstanding borrowings under the Revolving Loan, $2 million of undrawn letters of credit and $340 million reserved related to the floorplan sub-facility. As of March 31, 2016 , the borrowing base was $1,334 million based on the amount of eligible inventory and accounts receivable balances as of February 29, 2016. The Company could have borrowed up to an additional $908 million under the Revolving Loan as of March 31, 2016 . (2) The CDW UK Credit Facility is a multi-currency revolving credit facility, expiring on July 17, 2017, under which CDW UK is permitted to borrow an aggregate amount of £ 50.0 million ( $72 million ). Debt Covenants As of March 31, 2016 , the Company remained in compliance with the covenants under its various credit agreements, the most restrictive of which is under the credit agreement governing the Senior Secured Term Loan Facility ("Term Loan"). Under the Term Loan, there are restrictions on the ability of CDW to pay dividends, make share repurchases, redeem subordinated debt and engage in certain other transactions. As of March 31, 2016 , the amount of CDW’s restricted payment capacity under the Term Loan was $680 million . However, the Company is separately permitted to make restricted payments, so long as the total net leverage ratio is less than 3.25 on a pro forma basis. The total net leverage ratio was 2.8 as of March 31, 2016 . Fair Value The fair values of the 2022, 2023 and 2024 Senior Notes were estimated using quoted market prices for identical assets or liabilities that are traded in over-the-counter secondary markets that are not considered active. The fair value of the Term Loan was estimated using dealer quotes for identical assets or liabilities in markets that are not considered active. Consequently, the Company's long-term debt is classified as Level 2 within the fair value hierarchy. The fair value of the CDW UK Term Loan was estimated using a discounted cash flow analysis based on current incremental borrowing rates for similar arrangements. The approximate fair values and related carrying values of the Company's long-term debt, including current maturities and excluding unamortized discount and unamortized deferred financing costs, were as follows: (in millions) March 31, 2016 December 31, Fair value $ 3,338.2 $ 3,330.4 Carrying value 3,277.6 3,286.5

A reconciliation of basic weighted-average shares outstanding to diluted weighted-average shares outstanding is as follows: Three Months Ended March 31, (in millions) 2016 2015 Basic weighted-average shares outstanding 167.3 172.1 Effect of dilutive securities (1) 1.6 1.4 Diluted weighted-average shares outstanding (2) 168.9 173.5 (1) The dilutive effect of outstanding stock options, restricted stock units, restricted stock and Coworker Stock Purchase Plan units is reflected in the diluted weighted-average shares outstanding using the treasury stock method. (2) There were less than 1 million potential common shares excluded from diluted weighted-average shares outstanding for the three months ended March 31, 2016 and 2015 as their inclusion would have had an anti-dilutive effect.

The Company's offerings range from discrete hardware and software products to integrated IT solutions such as mobility, security, data center optimization, cloud computing, virtualization and collaboration.

Basis of Presentation, Policy	Basis of Presentation The unaudited interim Consolidated Financial Statements as of March 31, 2016 and for the three months ended March 31, 2016 and 2015 (the “Consolidated Financial Statements”) have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”) and the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”) for interim financial statements. Accordingly, certain information and footnote disclosures normally included in Consolidated Financial Statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. These Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2015 (the “December 31, 2015 Consolidated Financial Statements”). The significant accounting policies used in preparing these Consolidated Financial Statements were applied on a basis consistent with those reflected in the December 31, 2015 Consolidated Financial Statements. In the opinion of management, the Consolidated Financial Statements contain all adjustments (consisting of a normal, recurring nature) necessary to present fairly the Company's financial position, results of operations, comprehensive income, cash flows and changes in stockholders' equity as of the dates and for the periods indicated. The unaudited results of operations for such interim periods reported are not necessarily indicative of results for the full year.
Principles of Consolidation, Policy	Principles of Consolidation The accompanying Consolidated Financial Statements include the accounts of Parent and its 100% owned subsidiaries. All intercompany transactions and accounts are eliminated in consolidation.
Use of Estimates, Policy	Use of Estimates The preparation of the Consolidated Financial Statements in accordance with GAAP requires management to make use of certain estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the Consolidated Financial Statements and the reported amounts of revenue and expenses during the reported periods. The Company bases its estimates on historical experience and on various other assumptions that management believes are reasonable under the circumstances, the results of which form the basis for making judgments about carrying values of assets and liabilities that are not readily apparent from other sources. Actual results could differ from those estimates. The notes to the Consolidated Financial Statements contained in the December 31, 2015 Consolidated Financial Statements include an additional discussion of the significant accounting policies and estimates used in the preparation of the Company's Consolidated Financial Statements. There have been no material changes to the Company's significant accounting policies and estimates during the three months ended March 31, 2016 .

Schedule of Consideration Transferred	A summary of the total consideration transferred is as follows: (in millions) Acquisition-Date Fair Value Cash $ 291.6 Fair value of CDW common stock (1) 33.2 Fair value of previously held equity investment on the date of acquisition (2) 174.9 Total consideration $ 499.7 (1) The Company issued 2 million shares of CDW common stock. The fair value of the common stock was based on the closing market price on July 31, 2015 , adjusted for the lack of marketability as the shares of CDW common stock issued to the sellers are subject to a three -year lock up restriction from August 1, 2015 . One of the sellers granted 1 million stock options to certain CDW UK coworkers over his shares of CDW common stock received in the transaction. The fair value of these stock options was $22 million , which has been accounted for as post-combination stock-based compensation and is being amortized over the weighted­-average requisite service period of 3.2 years. Compensation expense for these options is included in Selling and administrative expenses in the Consolidated Statements of Operations. (2) As a result of the Company obtaining control over CDW UK, the Company’s previously held 35% equity investment was remeasured to fair value, resulting in a gain of $98 million included in Gain on remeasurement of equity investment in the Consolidated Statements of Operations. The fair value of the previously held equity investment was determined by management with the assistance of a third party valuation firm, based on information available as of the acquisition date.

Schedule of Long-term Debt Instruments [Table Text Block]	Fair Value The fair values of the 2022, 2023 and 2024 Senior Notes were estimated using quoted market prices for identical assets or liabilities that are traded in over-the-counter secondary markets that are not considered active.
