	Summary of Significant Accounting Policies
	Basis of Presentation
	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (GAAP) and applicable rules and regulations of the Securities and Exchange Commission regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. As such, the information included in this quarterly report on Form 10-Q should be read in conjunction with the consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2013.
	The condensed consolidated balance sheet as of December 31, 2013 included herein was derived from the audited financial statements as of that date, but does not include all disclosures including notes required by GAAP.
	The condensed consolidated financial statements include the accounts of Facebook, Inc. and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated.
	The accompanying condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full year ending December 31, 2014.
	There have been no changes to our significant accounting policies described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2013 that have had a material impact on our condensed consolidated financial statements and related notes.
	Use of Estimates
	Conformity with GAAP requires the use of estimates and judgments that affect the reported amounts in the condensed consolidated financial statements and accompanying notes. These estimates form the basis for judgments we make about the carrying values of our assets and liabilities, which are not readily apparent from other sources. We base our estimates and judgments on historical information and on various other assumptions that we believe are reasonable under the circumstances. GAAP requires us to make estimates and judgments in several areas, including, but not limited to, those related to revenue recognition, collectability of accounts receivable, contingent liabilities, fair value of financial instruments, fair value of acquired intangible assets and goodwill, useful lives of intangible assets and property and equipment, and income taxes. These estimates are based on management's knowledge about current events and expectations about actions we may undertake in the future. Actual results could differ materially from those estimates.

Earnings Per Share [Abstract]	'
Earnings per Share	'
	Earnings per Share
	We compute earnings per share (EPS) of Class A and Class B common stock using the two-class method required for participating securities. We consider restricted stock awards to be participating securities because holders of such shares have non-forfeitable dividend rights in the event of our declaration of a dividend for common shares.
	Undistributed earnings allocated to participating securities are subtracted from net income in determining net income attributable to common stockholders. Basic EPS is computed by dividing net income attributable to common stockholders by the weighted-average number of shares of our Class A and Class B common stock outstanding, adjusted for outstanding shares that are subject to repurchase.
	For the calculation of diluted EPS, net income attributable to common stockholders for basic EPS is adjusted by the effect of dilutive securities, including awards under our equity compensation plans. In addition, the computation of the diluted EPS of Class A common stock assumes the conversion of our Class B common stock to Class A common stock, while the diluted EPS of Class B common stock does not assume the conversion of those shares to Class A common stock. Diluted EPS attributable to common stockholders is computed by dividing the resulting net income attributable to common stockholders by the weighted-average number of fully diluted common shares outstanding.
	We have excluded 3 million and 18 million restricted stock units (RSUs) from the EPS calculation for the three months ended March 31, 2014 and 2013 because the impact would be anti-dilutive.
	Basic and diluted EPS are the same for each class of common stock because they are entitled to the same liquidation and dividend rights.
	The numerators and denominators of the basic and diluted EPS computations for our common stock were calculated as follows (in millions, except per share amounts):

	Long-term Debt
	In August 2013, we entered into a five-year senior unsecured revolving credit facility (2013 Revolving Credit Facility) that allows us to borrow up to $6.5 billion to fund working capital and general corporate purposes with interest payable on the borrowed amounts set at LIBOR plus 1.0%, as well as an annual commitment fee of 0.10% on the daily undrawn balance of the facility. We paid origination fees at closing of the 2013 Revolving Credit Facility, which fees are being amortized over the term of the facility. Any amounts outstanding under this facility will be due and payable on August 15, 2018. As of March 31, 2014, no amounts had been drawn down and we were in compliance with the covenants under this facility.

	Leases
	We entered into various capital lease arrangements to obtain property and equipment for our operations. Additionally, on occasion we have purchased property and equipment for which we have subsequently obtained capital financing under sale-leaseback transactions. These agreements are typically for three years, except for a building lease which is for 15 years, with interest rates ranging from 1% to 13%. The leases are secured by the underlying leased buildings, leasehold improvements, and equipment. We have also entered into various non-cancelable operating lease agreements for certain of our offices, equipment, land and data centers with original lease periods expiring between 2014 and 2029. We are committed to pay a portion of the related actual operating expenses under certain of these lease agreements. Certain of these arrangements have free rent periods or escalating rent payment provisions, and we recognize rent expense under such arrangements on a straight-line basis.
	Operating lease expense was $29 million and $41 million for the three months ended March 31, 2014 and 2013, respectively.
	Other Agreements
	In February 2014, we entered into an agreement to acquire WhatsApp Inc. (WhatsApp), a privately-held cross-platform mobile messaging company, for 183,865,778 shares of our Class A common stock and approximately $4 billion in cash, subject to certain adjustments such that the cash paid will comprise at least 25% of the aggregate transaction consideration. Upon closing, we will also grant 45,966,445 RSUs to WhatsApp employees. The value of the equity component of the final purchase price and RSUs granted will be determined for accounting purposes based on the fair value of our common stock on the closing date. This acquisition is subject to customary closing conditions, including certain regulatory approvals, and is expected to close later in 2014. We have agreed to pay a termination fee to WhatsApp of $1 billion in cash and issue a number of shares of our Class A common stock equal to $1 billion, based on the average closing price of the ten trading days preceding such termination, if the closing of this acquisition has not occurred by August 19, 2014 (or August 19, 2015, if as of August 19, 2014, all closing conditions have been completed except for the receipt of certain regulatory approvals).
	In March 2014, we entered into an agreement to acquire Oculus VR, Inc. (Oculus), a privately-held company developing virtual reality technology, for 23,071,377 shares of our Class B common stock and approximately $400 million in cash. The value of the equity component of the final purchase price will be determined for accounting purposes based on the fair value of our common stock on the closing date. Further, up to an additional 3,460,706 shares of our Class B common stock and $60 million in cash would be payable upon the completion of certain milestones. The earn-out portion that would be payable to employee stockholders is also subject to continuous employment through the applicable payment dates. This acquisition is subject to customary closing conditions, including certain regulatory approvals, and is expected to close in the second quarter of 2014.
	Contingencies
	Beginning on May 22, 2012, multiple putative class actions, derivative actions, and individual actions were filed in state and federal courts in the United States and in other jurisdictions against us, our directors, and/or certain of our officers alleging violation of securities laws or breach of fiduciary duties in connection with our initial public offering (IPO) and seeking unspecified damages. We believe these lawsuits are without merit, and we intend to continue to vigorously defend them. On October 4, 2012, on our motion, the vast majority of the cases in the United States, along with multiple cases filed against The NASDAQ OMX Group, Inc. and The Nasdaq Stock Market LLC (collectively referred to herein as NASDAQ) alleging technical and other trading-related errors by NASDAQ in connection with our IPO, were ordered centralized for coordinated or consolidated pre-trial proceedings in the U.S. District Court for the Southern District of New York. On February 13, 2013, the court granted our motion to dismiss four derivative actions against our directors and certain of our officers with leave to amend. On December 18, 2013, the court denied our motion to dismiss the consolidated securities class action. On December 23, 2013, the court granted our motion to dismiss, and denied the plaintiffs’ motion to remand to state court, another derivative action against our directors and certain of our officers; on February 28, 2014, the plaintiffs in this action filed a notice of appeal. In addition, the events surrounding our IPO have been the subject of various government inquiries, and we are cooperating with those inquiries.
	We are also party to various legal proceedings and claims that arise in the ordinary course of business. Among these pending legal matters, one case is currently scheduled for trial in the near future. Rembrandt Social Media, LP v. Facebook, Inc., et al., was scheduled to begin trial December 2013 in the U.S. District Court for the Eastern District of Virginia. In the Rembrandt case, the plaintiff alleges that we infringe certain patents held by the plaintiff. The plaintiff is seeking significant monetary damages and equitable relief. The trial date was vacated in December 2013 pending appeal, which the court of appeals declined to hear on April 7, 2014. Accordingly, this case is in the process of being rescheduled for trial, which will likely take place between May and July of 2014. We believe the claims made by the plaintiff in the Rembrandt case are without merit, and we intend to defend ourselves vigorously.
	With respect to our outstanding legal matters, we believe that the amount or estimable range of reasonably possible loss will not, either individually or in the aggregate, have a material adverse effect on our business, consolidated financial position, results of operations, or cash flows. However, the outcome of litigation is inherently uncertain. Therefore, if one or more of these legal matters were resolved against us for amounts in excess of management's expectations, our results of operations and financial condition, including in a particular reporting period, could be materially adversely affected.

	Share-based Compensation Plans
	We maintain two share-based employee compensation plans: the 2012 Equity Incentive Plan (2012 Plan) and the 2005 Stock Plan (collectively, Stock Plans). Our 2012 Plan serves as the successor to our 2005 Stock Plan and provides for the issuance of incentive and nonstatutory stock options, restricted stock awards, stock appreciation rights, RSUs, performance shares and stock bonuses to qualified employees, directors and consultants. Outstanding awards under the 2005 Stock Plan continue to be subject to the terms and conditions of the 2005 Stock Plan. The maximum term for stock options granted under the 2012 Plan may not exceed ten years from the date of grant. Our 2012 Plan will terminate ten years from the date of approval unless it is terminated earlier by our compensation committee.
	We have initially reserved 25,000,000 shares of our Class A common stock for issuance under our 2012 Plan, which amount increases on the first day of January of each year through 2022 based on a formula or as determined by the board of directors. Our board of directors elected not to increase the number of shares reserved for issuance in 2014. In addition, shares available for grant under the 2005 Stock Plan, which were reserved but not issued or subject to outstanding awards under the 2005 Stock Plan as of the effective date of our IPO, were added to the reserves of the 2012 Plan and shares that were withheld in connection with the net settlement of RSUs were also added to the reserves of the 2012 Plan. In January 2014, we began requiring that employees sell a portion of the shares that they receive upon the vesting of RSUs in order to cover any required withholding taxes, rather than our previous approach of net share settlement.
	In February 2014, we terminated our 2005 Officers' Plan as the only outstanding option issued under this plan had been exercised in full.
	The following table summarizes the stock option activity under the Stock Plans during the three months ended March 31, 2014:
		Shares Subject to Options Outstanding

	-1	The aggregate intrinsic value is calculated as the difference between the exercise price of the underlying stock option awards and the closing price of our Class A common stock of $60.24 on March 31, 2014.
	The aggregate intrinsic value of the options exercised was $161 million and $311 million for the three months ended March 31, 2014 and 2013, respectively.
	The following table summarizes the activities for our unvested RSUs for the three months ended March 31, 2014:

	Forfeited	(2,575	)	31.55
	Unvested at March 31, 2014	106,369		$	35.07
	The fair value as of the respective vesting dates of RSUs that vested during the three months ended March 31, 2014 and 2013 was $952 million and $485 million, respectively.
	As of March 31, 2014, there was $3.67 billion of unrecognized share-based compensation expense, of which $3.42 billion is related to RSUs and $254 million is related to restricted shares and stock options. This unrecognized compensation expense is expected to be recognized over a weighted-average period of approximately three years.

Income Tax Disclosure [Abstract]	'
Income Taxes	'
	Income Taxes
	Our tax provision for interim periods is determined using an estimate of our annual effective tax rate, adjusted for discrete items arising in that quarter. In each quarter we update our estimate of the annual effective tax rate, and if our estimated annual tax rate changes, we make a cumulative adjustment in that quarter. Our quarterly tax provision, and our quarterly estimate of our annual effective tax rate, are subject to significant volatility due to several factors, including our ability to accurately predict our income (loss) before provision for income taxes in multiple jurisdictions, including the portions of our share-based compensation that will not generate tax benefits, and the effects of acquisitions and the integration of those acquisitions. In addition, our effective tax rate can be more or less volatile based on the amount of income before provision for income taxes.
	Our effective tax rate has exceeded the U.S. statutory rate primarily because of the effect of non-deductible share-based compensation and the impact of acquiring intellectual property and integrating it into our business. Our effective tax rate in the future will depend on the portion of our profits earned within and outside the United States, which will also be affected by our methodologies for valuing our intellectual property and intercompany transactions.
	We are subject to taxation in the United States and various other state and foreign jurisdictions. The material jurisdictions in which we are subject to potential examination include the United States and Ireland. We are under examination by the Internal Revenue Service (IRS) for our 2008, 2009 and 2010 tax years. We believe that adequate amounts have been reserved for any adjustments that may ultimately result from these examinations, and we do not anticipate a significant impact to our gross unrecognized tax benefits within the next 12 months related to these years. Our 2011 and subsequent tax years remain subject to examination by the IRS and all tax years starting in 2008 remain subject to examination in Ireland. We remain subject to possible examinations or are undergoing audits in various other jurisdictions that are not anticipated to be material to our financial statements.
	Although the timing of the resolution, settlement, and closure of any audit is highly uncertain, it is reasonably possible that the balance of gross unrecognized tax benefits could significantly change in the next 12 months. However, given the number of years remaining that are subject to examination, we are unable to estimate the full range of possible adjustments to the balance of gross unrecognized tax benefits.

	Basis of Presentation
	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (GAAP) and applicable rules and regulations of the Securities and Exchange Commission regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. As such, the information included in this quarterly report on Form 10-Q should be read in conjunction with the consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2013.
	The condensed consolidated balance sheet as of December 31, 2013 included herein was derived from the audited financial statements as of that date, but does not include all disclosures including notes required by GAAP.
	The condensed consolidated financial statements include the accounts of Facebook, Inc. and its wholly owned subsidiaries. All intercompany balances and transactions have been eliminated.
	The accompanying condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full year ending December 31, 2014.
	There have been no changes to our significant accounting policies described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2013 that have had a material impact on our condensed consolidated financial statements and related notes.
Use of Estimates	'
	Use of Estimates
	Conformity with GAAP requires the use of estimates and judgments that affect the reported amounts in the condensed consolidated financial statements and accompanying notes. These estimates form the basis for judgments we make about the carrying values of our assets and liabilities, which are not readily apparent from other sources. We base our estimates and judgments on historical information and on various other assumptions that we believe are reasonable under the circumstances. GAAP requires us to make estimates and judgments in several areas, including, but not limited to, those related to revenue recognition, collectability of accounts receivable, contingent liabilities, fair value of financial instruments, fair value of acquired intangible assets and goodwill, useful lives of intangible assets and property and equipment, and income taxes. These estimates are based on management's knowledge about current events and expectations about actions we may undertake in the future. Actual results could differ materially from those estimates.
