	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.
	Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board issued guidance related to revenue from contracts with customers. Under this guidance, revenue is recognized when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. The updated standard will replace most existing revenue recognition guidance under GAAP when it becomes effective and permits the use of either the retrospective or cumulative effect transition method. Early adoption is not permitted. The updated standard will be effective for us in the first quarter of 2017. We have not yet selected a transition method and we are currently evaluating the effect that the updated standard will have on our consolidated financial statements and related disclosures.

Acquisitions

	Acquisitions
	In July 2014, we completed our acquisition of Oculus VR, Inc. (Oculus), a privately-held company developing virtual reality technology that is expected to expand our platform. Pursuant to the merger agreement, we issued 23 million shares of our Class B common stock and paid $400 million in cash. Furthermore, up to an additional three million shares of our Class B common stock and $60 million in cash will be payable contingent upon the completion of certain milestones. We determined the acquisition-date fair value of the contingent consideration liability, based on the likelihood of payment related to the contingent earn-out clauses, as part of the consideration transferred. For contingent consideration to be settled in common stock, we use the fair value of the shares as of the acquisition date, which is remeasured on each reporting date until settlement. See Note 5 “Fair Value Measurements" for subsequent measurements of this contingent liability. The earn-out portion that would be payable to employee equityholders is subject to continuous employment through the applicable payment dates and as such has been excluded from purchase consideration transferred and accounted for as share-based compensation and other compensation expense.
	We have accounted for this acquisition as a business combination. This method requires, among other things, that assets acquired and liabilities assumed in a business combination be recognized at their fair values as of the acquisition date and that in-process research and development (IPR&D) be recorded at fair value on the balance sheet regardless of the likelihood of success of the related product or technology.
	The following table summarizes the components of the purchase consideration transferred based on the closing price of our common stock as of the acquisition date (in millions):
	Cash	$	400
	Common stock	1,601
	Less: post-acquisition share-based compensation and other compensation expense	(297		)
	Less: cash acquired on acquisition date	(20		)
	Total purchase consideration, excluding contingent consideration	$	1,684
	Contingent consideration	169
	Purchase consideration	$	1,853
	Of the $297 million of share-based compensation and other compensation expense excluded from the purchase consideration above, approximately $13 million was recognized as share-based compensation at closing as a result of the vesting provisions of employee replacement awards on the acquisition date. The remaining $284 million is subject to continuous employment and will be recognized as share-based compensation and other compensation expense over the required service period of four years.
	The fair value of assets acquired and liabilities assumed from our acquisition of Oculus was based on a preliminary valuation and our estimates and assumptions are subject to change within the measurement period. The primary areas of the purchase price that are not yet finalized are related to income taxes and residual goodwill. Measurement period adjustments that we determine to be material will be applied retrospectively to the period of acquisition in our condensed consolidated financial statements and, depending on the nature of the adjustments, other periods subsequent to the period of acquisition could also be affected.
	In the nine months ended September 30, 2014, we also completed other business acquisitions for total cash consideration of $456 million. These acquisitions were not material to our condensed consolidated financial statements either individually or in the aggregate. We have included the financial results of Oculus and the other business acquisitions, which are not material, in our condensed consolidated financial statements from their respective dates of acquisition. Pro forma historical results of operations related to our acquisitions of Oculus and the other business acquisitions during the nine months ended September 30, 2014 have not been presented because they are not material to our condensed consolidated statements of income, either individually or in the aggregate.
	The following table summarizes the allocation of the fair values of the assets acquired and liabilities assumed, including those items that are still preliminary, and the related useful lives, where applicable:
		Oculus				Other
		(in millions)			Useful lives (in years)	(in millions)			Useful lives (in years)
	Finite-lived intangible assets:
	Acquired technology	$	235		5	$	62		5-Mar
	Tradename and other	132			7-Feb	87			5-Mar
	IPR&D intangible assets	60				—
	Net assets acquired	—				104
	Deferred tax liabilities	(107		)		(41		)
	Net assets acquired	$	320			$	212
	Goodwill	1,533				244
	Total fair value	$	1,853			$	456
	IPR&D intangible assets represent the value assigned to acquired research and development projects that, as of the acquisition date had not established technological feasibility and had no alternative future use. The IPR&D intangible assets are capitalized and accounted for as indefinite-lived intangible assets and will be subject to impairment testing until completion or abandonment of the projects. Upon successful completion of each project and launch of the product, we will make a separate determination of useful life of the IPR&D intangible assets and the related amortization will be recorded as an expense over the estimated useful life of the specific projects.
	Goodwill generated from all business acquisitions completed during the nine months ended September 30, 2014 is primarily attributable to expected synergies from future growth, from potential monetization opportunities and, also for Oculus, as a potential to expand our platform. All goodwill generated during this period is not deductible for tax purposes.

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. Basic and dilutive securities in our basic and diluted EPS calculation for the three and nine months ended September 30, 2014 do not include contingent earn-out shares resulting from our acquisition of Oculus. Issuance of these earn-out shares is dependent upon the completion of certain milestones. These milestones were not met as of September 30, 2014 and accordingly, these shares are excluded from the effect of basic and dilutive securities.
	We have also excluded 15 million restricted stock units (RSUs) from the EPS calculation for the nine months ended September 30, 2013 because the impact would be anti-dilutive. Shares excluded from the calculation were not material for the three and nine months ended September 30, 2014 and the three months ended September 30, 2013.
	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):

	We classify our cash equivalents and marketable securities within Level 1 or Level 2 because we use quoted market prices or alternative pricing sources and models utilizing market observable inputs to determine their fair value.
	We classify our contingent consideration liability in connection with our acquisition of Oculus within Level 3 as factors used to develop the estimated fair value are unobservable inputs that are not supported by market activity. We estimate the fair value of our contingent consideration liability based on the present value of probability-weighted future cash flows related to the contingent earn-out criteria and the fair value of our common stock on each reporting date. Our fair value estimate of this liability was $169 million at the date of acquisition and changes in the fair value of the contingent consideration liability subsequent to the acquisition date, such as changes in the probability assessment and the fair value of our common stock, are recognized in earnings in the period when the change in the estimated fair value occurs. During the three and nine months ended September 30, 2014, we recognized a $23 million change in the fair value of our contingent consideration liability in research and development expense in our condensed consolidated statements of income primarily due to the change in the fair value of our common stock.

	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 September 30, 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 $31 million and $94 million for the three and nine months ended September 30, 2014, respectively, and $28 million and $101 million for the three and nine months ended September 30, 2013, respectively.
	Other Agreement
	In April 2014, we entered into a non-cancelable contractual commitment to spend a minimum of $140 million on network services over a period of 10 years.
	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. 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. In a series of rulings in 2013 and 2014, the court denied our motion to dismiss the consolidated securities class action and granted our motions to dismiss the derivative actions against our directors and certain of our officers. The plaintiffs in four of these derivative actions have filed notices of appeal. In addition, the events surrounding our IPO became the subject of various state and federal government inquiries. In May 2014, the Securities and Exchange Commission (SEC) notified us that it had terminated its inquiry and that no enforcement action had been recommended by the SEC.
	We are also party to various legal proceedings and claims that arise in the ordinary course of business. 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 nine months ended September 30, 2014:

	-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 $79.04 on September 30, 2014.
	The aggregate intrinsic value of options exercised was $117 million and $321 million for the three and nine months ended September 30, 2014, respectively, and $586 million and $1.17 billion for the three and nine months ended September 30, 2013, respectively.

	Forfeited	(7,948	)	33.87
	Unvested at September 30, 2014	96,417		$	42.64
	The fair value as of the respective vesting dates of RSUs that vested during the three and nine months ended September 30, 2014 was $652 million and $2.19 billion, respectively, and $326 million and $1.15 billion, respectively, during the three and nine months ended September 30, 2013.
	As of September 30, 2014, there was $4.17 billion of unrecognized share-based compensation expense, of which $3.71 billion is related to RSUs and $464 million is related to restricted shares, shares with performance conditions related to our contingent consideration liability, and stock options. This unrecognized compensation expense is expected to be recognized over a weighted-average period of approximately three years.

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 potential examination by the IRS and all tax years starting in 2008 remain subject to potential 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.
	Our gross unrecognized tax benefits were $1.51 billion and $1.32 billion as of September 30, 2014 and December 31, 2013, respectively. If the gross unrecognized tax benefits as of September 30, 2014 were realized in a future period, this would result in a tax benefit of $1.03 billion within our provision of income taxes at such time. Our existing tax positions will continue to generate an increase in unrecognized tax benefits in future periods.
	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.

	On October 6, 2014, we completed our acquisition of WhatsApp Inc. (WhatsApp), a privately-held cross-platform mobile messaging company that is expected to provide us with strategic advantages in the mobile ecosystem and expand our mobile messaging offerings. Pursuant to the merger agreement, we issued approximately 178 million shares of our Class A common stock and paid $4.59 billion in cash. We will also grant 46 million RSUs to WhatsApp employees.
	Upon acquisition, WhatsApp became a wholly-owned subsidiary of Facebook. The acquisition will be accounted for as a business combination. The following table summarizes the components of the preliminary purchase consideration transferred based on the closing price of $77.56 per share of our Class A common stock on the acquisition close date (in millions):
	Cash		$	4,589
	Common stock		13,787
	Less: post-acquisition share-based compensation and other compensation expense		(1,067		)
	Less: cash and promissory notes acquired on acquisition date		(116		)
	Purchase consideration		$	17,193
	Of the $1.07 billion of share-based compensation and other compensation expense excluded from the purchase consideration above, approximately $188 million will be accounted for as share-based compensation expense at closing as a result of the vesting provisions of WhatsApp employee awards on the acquisition date. The remaining $879 million (approximately 8.5 million shares of Class A common stock and $219 million in cash) is subject to continuous employment and will be recognized as share-based compensation and other compensation expense over the required service period of up to three years.
	The following table summarizes the preliminary allocation of the assets acquired and liabilities assumed based on their fair values as of the acquisition date and related estimated useful lives of the finite-lived intangible assets acquired (in millions, except estimated useful life):
					Estimated useful life
					(in years)
	Finite-lived intangible assets:

	Deferred tax liabilities	(916		)
	Net assets acquired	$	1,834
	Goodwill	15,359
		$	17,193
	The $15.36 billion of goodwill is primarily attributable to expected synergies from future growth, from potential monetization opportunities, from strategic advantages provided in the mobile ecosystem and from expansion of our mobile messaging offerings. Goodwill is not expected to be deductible for tax purposes.
	The following unaudited pro forma information presents the combined results of operations as if the acquisition had been completed on January 1, 2013, the beginning of the comparable prior annual reporting period. The unaudited pro forma results include: (i) amortization associated with preliminary estimates for the acquired intangible assets; (ii) recognition of the post-acquisition share-based compensation and other compensation expense; (iii) share-based compensation expense related to the 46 million RSUs we will grant to WhatsApp employees; and (iv) the associated tax impact on these unaudited pro forma adjustments.
	The unaudited pro forma results do not reflect any cost saving synergies from operating efficiencies or the effect of the incremental costs incurred in integrating the two companies. Accordingly, these unaudited pro forma results are presented for informational purpose only and are not necessarily indicative of what the actual results of operations of the combined company would have been if the acquisition had occurred at the beginning of the period presented, nor are they indicative of future results of operations (in millions):

	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.
Recent Accounting Pronouncements	'
	Recent Accounting Pronouncements
	In May 2014, the Financial Accounting Standards Board issued guidance related to revenue from contracts with customers. Under this guidance, revenue is recognized when promised goods or services are transferred to customers in an amount that reflects the consideration that is expected to be received for those goods or services. The updated standard will replace most existing revenue recognition guidance under GAAP when it becomes effective and permits the use of either the retrospective or cumulative effect transition method. Early adoption is not permitted. The updated standard will be effective for us in the first quarter of 2017. We have not yet selected a transition method and we are currently evaluating the effect that the updated standard will have on our consolidated financial statements and related disclosures.
