Summary of Significant Accounting Policies [Abstract] |
Consolidation, Variable Interest Entity, Policy | Our merchandise and service trusts are variable interest entities. We have determined that we are the primary beneficiary of these trusts, as we absorb a majority of the losses and returns associated with these trusts. Our trust investments detailed in Notes 4 and 5 are also accounted for as variable interest entities. Our merchandise and service trusts are variable interest entities.

We have determined that we are the primary beneficiary of these trusts, as we absorb a majority of the losses and returns associated with these trusts. The trust investments detailed in Notes 3 and 4 are also accounted for as variable interest entities.
Funeral and Cemetery cash flow | Cash flows from preneed contracts are presented as operating cash flows in our unaudited condensed Consolidated Statement of Cash Flows. Cash flows from preneed cemetery contracts are presented as operating cash flows in our unaudited condensed Consolidated Statement of Cash Flows. Cash flows from cemetery perpetual care trusts are presented as operating cash flows in our unaudited condensed Consolidated Statement of Cash Flows.
Revenue Recognition, Deferred Revenue | These earnings are recorded in Deferred preneed funeral revenue until the merchandise is delivered or the service is performed. These earnings are recorded in Deferred preneed cemetery revenue until the merchandise is delivered or the service is performed.
Fair Value of Financial Instruments, Policy | Where quoted prices are available in an active market, securities are classified as Level 1 investments pursuant to the fair value measurements hierarchy. Where quoted market prices are not available for the specific security, fair values are estimated by using either quoted prices of securities with similar characteristics or an income approach fair value model with observable inputs that include a combination of interest rates, yield curves, credit risks, prepayment speeds, ratings, and tax-exempt status. These funds are classified as Level 2 investments pursuant to the fair value measurements hierarchy. The valuation of other investments requires management judgment due to the absence of quoted market prices, inherent lack of liquidity, and the long-term nature of such assets. These funds are classified as Level 3 investments pursuant to the Where quoted prices are available in an active market, securities held by the trusts are classified as Level 1 investments pursuant to the fair value measurements hierarchy.

The valuation of other investments requires management judgment due to the absence of quoted market prices, inherent lack of liquidity, and the long-term nature of such assets. These funds are classified as Level 3 investments pursuant to the fair value measurements hierarchy. The fair values of our long-term, fixed-rate loans were estimated using market prices for those loans, and therefore they are classified within Level 2 of the fair value measurements hierarchy. The Term Loan, Bank Credit Facility agreement and the mortgage and other debt are classified within Level 3 of the fair value measurements hierarchy. The fair values of these instruments have been estimated using a discounted cash flow analysis based on our incremental borrowing rate for similar borrowing arrangements.
Revenue Recognition, Policy | Earnings from all our merchandise and service trust investments are recognized in revenue when merchandise is delivered or a service is performed. Fees charged by our wholly-owned registered investment advisor are also included in current revenue. In addition, we are entitled to retain, in certain jurisdictions, a portion of collected customer payments when a customer cancels a preneed contract; these amounts are also recognized in current revenue in the period in which they are earned.

In addition, we are entitled to retain, in certain jurisdictions, a portion of collected customer payments when a customer cancels a preneed contract; these amounts are also recognized in current revenue in the period in which they are earned. Distributable earnings from these cemetery perpetual care trust investments are recognized in current cemetery revenue to the extent we incur qualifying cemetery maintenance costs. Fees charged by our wholly-owned registered investment advisor are also included in current revenue.
Marketable Securities, Available-for-sale Securities, Policy | We assess our trust investments for other-than-temporary declines in fair value on a quarterly basis. Impairment charges resulting from this assessment are recognized as investment losses in Other expense, net and a decrease to Preneed funeral receivables, net and trust investments. These investment losses, if any, are offset by the corresponding reclassification in Other expense, net, which reduces Deferred preneed receipts held in trust.

Impairment charges resulting from this assessment are recognized as investment losses in Other expense, net and a decrease to Cemetery perpetual care trust investments. These investment losses, if any, are offset by the corresponding reclassification in Other expense, net, which reduces Care trusts’ corpus.
Earnings Per Share, Policy | Basic earnings per common share (EPS) excludes dilution and is computed by dividing Net income attributable to common stockholders by the weighted average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if securities or other obligations to issue common stock were exercised or converted into common stock or resulted in the issuance of common shares that then shared in our earnings. A reconciliation of the numerators and denominators of the basic and diluted EPS computations is presented below:

Segment Reporting, Policy | Our operations are both product-based and geographically-based, and the reportable operating segments presented below include our funeral and cemetery operations.
Share-based Compensation, Option and Incentive Plans Policy | We utilize the Black-Scholes option valuation model for estimating the fair value of our stock options.
Consolidation, Policy | Principles of Consolidation and Basis of Presentation Our unaudited condensed consolidated financial statements include the accounts of Service Corporation International (SCI) and all subsidiaries in which we hold a controlling financial interest. Our financial statements also include the accounts of the merchandise and service trusts and cemetery perpetual care trusts in which we have a variable interest and are the primary beneficiary. Our interim condensed consolidated financial statements are unaudited but include all adjustments, consisting of normal recurring accruals and any other adjustments, which management considers necessary for a fair statement of our results for these periods. Our unaudited condensed consolidated financial statements have been prepared in a manner consistent with the accounting policies described in our Annual Report on Form 10-K for the year ended December 31, 2015, unless otherwise disclosed herein, and should be read in conjunction therewith. The accompanying year-end condensed Consolidated Balance Sheet data was derived from audited financial statements, but does not include all disclosures required by accounting principles generally accepted in the United States of America. Operating results for interim periods are not necessarily indicative of the results that may be expected for the full year period.
Use of Estimates, Policy | Use of Estimates in the Preparation of Financial Statements The preparation of the unaudited condensed consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions as described in our Annual Report on Form 10-K for the year ended December 31, 2015. These estimates and assumptions may affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the unaudited condensed consolidated financial statements and the reported amounts of revenue and expenses during the reporting periods. As a result, actual results could differ from these estimates.
New Accounting Pronouncements, Policy [Policy Text Block] | Accounting Standards Adopted in 2016 Consolidation In February 2015, the Financial Accounting Standards Board (FASB) amended "Consolidation" to revise the consolidation model for limited partnerships, variable interest entities, and certain investment funds. Further, the amendment provides guidance on how fee arrangements and related parties should be considered when determining whether to consolidate variable interest entities. As a result of this amendment, all legal entities were reevaluated to determine if they should be consolidated. We adopted the amendment effective January 1, 2016, with no impact our consolidated results of operations, consolidated financial position, and cash flows. Debt Issuance Costs In April 2015, the FASB amended "Interest—Imputation of Interest" to simplify the presentation of debt issuance costs on the balance sheet. Prior to adoption of this amendment, debt issuance costs were included in Other current assets and Deferred charges and other assets on our unaudited condensed Consolidated Balance Sheet. The amendment requires that these costs instead be presented as a direct deduction from the carrying amount of Current maturities of long-term debt and Long-term debt, consistent with the presentation of debt discounts. In August 2015, the FASB issued an additional amendment that provides additional guidance to "Interest—Imputation of Interest" since it did not address presentation or subsequent measurement of debt issuance costs related to line-of-credit arrangements. The amendment noted that the SEC staff would not object to an entity deferring and presenting debt issuance costs as an asset and subsequently amortizing the deferred debt issuance costs ratably over the term of the line-of-credit arrangement, regardless of whether there are any outstanding borrowings on the line-of-credit arrangement. This change does not impact the manner in which the debt issuance costs are expensed over the term of the debt. We have retrospectively adopted the change in presentation effective January 1, 2016. As a result, we recast our Consolidated Balance Sheet as of December 31, 2015 to reduce Other current assets and Current maturities of long-term debt by $8.4 million and to reduce Deferred charges and other assets and Long-term debt by $34.1 million. Cloud Computing Arrangements In April 2015, the FASB amended "Intangibles—Goodwill and Other—Internal-Use Software" to provide guidance on whether a cloud computing arrangement contains a software license. If a cloud computing arrangement includes a software license, then we should account for the software license element of the arrangement consistent with the acquisition of other software licenses. If a cloud computing arrangement does not include a software license, we should account for the arrangement as a service contract. We adopted the amendment effective January 1, 2016, with no impact on our consolidated results of operations, consolidated financial position, and cash flows. Fair Value Measurements In May 2015, the FASB amended "Fair Value Measurements" to remove the requirement to disclose the fair value measurement hierarchy level associated with investments measured at net asset value as a practical expedient. Other disclosures required by the standard for these assets remain the same. This amendment does not change the underlying accounting for these investments. We retrospectively adopted the amendment effective January 1, 2016, and have made the appropriate disclosures in Notes 3, 4, and 5. Business Combinations In September 2015, the FASB amended "Business Combinations" to eliminate the requirement for an acquirer in a business combination to account for measurement-period adjustments retrospectively. Under the new guidance, acquirers must recognize measurement-period adjustments in the period in which they determine the amount of the adjustment. We adopted the amendment on January 1, 2016 and it will be applied prospectively to measurement-period adjustments occurring after that date, if any. Recently Issued Accounting Standards Revenue Recognition In May 2014, the FASB issued "Revenue from Contracts with Customers" which supersedes the revenue recognition requirements in "Revenue Recognition" and most industry-specific guidance. This new standard is based on the principle that revenue is recognized to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. It also requires additional disclosure about the nature, amount, and timing of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to obtain or fulfill a contract. Additionally, the new standard requires the deferral of direct incremental selling costs to the period in which the underlying revenue is recognized. In August 2015, the FASB issued an amendment that defers implementation of "Revenue from Contracts with Customers" for all entities by one year. The new standard will be effective for us beginning January 1, 2018 and we intend to implement the standard with the modified retrospective approach, which recognizes the cumulative effect of application recognized on that date. We are evaluating the impact of adoption on our consolidated results of operations, consolidated financial position, and cash flows. Inventory In July 2015, the FASB amended "Inventory" to state that an entity using an inventory method other than last-in, first out ("LIFO") or the retail inventory method should measure inventory at the lower of cost and net realizable value. The new guidance clarifies that net realizable value is the estimated selling prices in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. The new guidance is effective for us on January 1, 2017, and we are still evaluating the impact of adoption on our consolidated results of operations, consolidated financial position, and cash flows. Financial Instruments In January 2016, the FASB amended "Financial Instruments" to provide additional guidance on the recognition and measurement of financial assets and liabilities. The amendment requires investments in equity instruments to be measured at fair value with changes in fair value reflected in net income. The amendment also changes the guidance for debt securities held at amortized cost and liabilities under the fair value option. The new guidance is effective for us on January 1, 2018, and we are still evaluating the impact of adoption on our consolidated results of operations, consolidated financial position, and cash flows. Leases In February 2016, the FASB amended "Leases" to increase transparency and comparability among organizations. Under the new standard, an entity will be required to recognize lease assets and liabilities on its balance sheet and disclose key information about leasing arrangements. In addition, the new standard offers specific accounting guidance for a lessee, a lessor, and sale and leaseback transactions. Lessees and lessors are required to disclose qualitative and quantitative information about leasing arrangements to enable a user of the financial statements to assess the amount, timing, and uncertainty of cash flows arising from leases. This new standard will be effective for us on January 1, 2019. We are evaluating the impact of adoption on our consolidated results of operations, consolidated financial position, and cash flows. Stock Compensation In March 2016, the FASB amended "Stock Compensation" to simplify certain aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. The new guidance is effective for us on January 1, 2017, and we are still evaluating the impact of adoption on our consolidated results of operations, consolidated financial position, and cash flows.

- Definition Disclosure of accounting policy for revenue recognition. If the entity has different policies for different types of revenue transactions, the policy for each material type of transaction is generally disclosed.
