Accounting Policies [Abstract]
Income Tax, Policy [Policy Text Block]	For interim tax reporting we estimate one single effective tax rate, which is applied to the year-to-date ordinary income/(loss). Tax effects of significant unusual or infrequently occurring items are excluded from the estimated annual effective tax rate calculation and recognized in the interim period in which they occur.
Basis of Accounting and Intercompany Transactions [Abstract]
Basis of Accounting and Intercompany Transactions [Policy Text Block]	The consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the United States of America (“GAAP”) for interim financial information, and instructions to the Quarterly Report on Form 10-Q and Rule 10-01 of Regulation S-X. In the opinion of management, these unaudited financial statements include all adjustments considered necessary for a fair statement of the results of operations and financial condition for interim periods for Ford Motor Credit Company LLC, its consolidated subsidiaries and consolidated VIEs in which Ford Motor Credit Company LLC is the primary beneficiary (collectively referred to herein as “Ford Credit,” “we,” “our,” or “us”). Results for interim periods should not be considered indicative of results for any other interim period or for the full year. Reference should be made to the financial statements contained in our Annual Report on Form 10-K for the year ended December 31, 2017 (“2017 Form 10-K Report”). We are an indirect, wholly owned subsidiary of Ford Motor Company (“Ford”).
Reclassifications [Abstract]
Comparability of Prior Year Financial Data, Policy [Policy Text Block]	We reclassified certain prior period amounts in our consolidated financial statements to conform to current year presentation.
Loans and Leases Receivable Disclosure [Abstract]
Finance, Loans and Leases Receivable, Policy [Policy Text Block]	A restructuring of debt constitutes a TDR if we grant a concession to a debtor for economic or legal reasons related to the debtor’s financial difficulties that we otherwise would not consider. Consumer and non-consumer receivables that have a modified interest rate below market rate or that were modified in reorganization proceedings pursuant to the U.S. Bankruptcy Code, except non-consumer receivables that are current with minimal risk of loss, are considered to be TDRs. We do not grant concessions on the principal balance of our receivables. If a receivable is modified in a reorganization proceeding, all payment requirements of the reorganization plan need to be met before remaining balances are forgiven. Finance receivables involved in TDRs are specifically assessed for impairment. Impaired consumer receivables include accounts that have been rewritten or modified in reorganization proceedings pursuant to the U.S. Bankruptcy Code that are considered to be Troubled Debt Restructurings (“TDRs”), as well as all accounts greater than 120 days past due. Impaired non-consumer receivables represent accounts with dealers that have weak or poor financial metrics or dealer financing that has been modified in TDRs. The accrual of revenue is discontinued at the time a receivable is determined to be uncollectible. Accounts may be restored to accrual status only when a customer settles all past-due deficiency balances and future payments are reasonably assured. For receivables in non-accrual status, subsequent financing revenue is recognized only to the extent a payment is received. Payments are generally applied first to outstanding interest and then to the unpaid principal balance.
Derivative Instruments and Hedging Activities Disclosure [Abstract]
Derivatives, Policy [Policy Text Block]	We have elected to apply hedge accounting to certain derivatives. Derivatives that are designated in hedging relationships are evaluated for effectiveness using regression analysis at the time they are designated and throughout the hedge period. Some derivatives do not qualify for hedge accounting; for others, we elect not to apply hedge accounting.
Restricted Cash [Abstract]
Restricted Cash, Policy [Policy Text Block]	Restricted cash primarily includes cash held to meet certain local governmental and regulatory reserve requirements and cash held under the terms of certain contractual agreements. Restricted cash does not include required minimum balances or cash securing debt issued through securitization transactions.
Commitments and Contingencies Disclosure [Abstract]
Guarantees and Indemnifications Policies [Policy Text Block]	We accrue for matters when losses are deemed probable and reasonably estimable. In evaluating matters for accrual and disclosure purposes, we take into consideration factors such as our historical experience with matters of a similar nature, the specific facts and circumstances asserted, the likelihood that we will prevail, and the severity of any potential loss. We reevaluate and update our accruals as matters progress over time. For nearly all of our matters, where our historical experience with similar matters is of limited value (i.e., “non-pattern matters”), we evaluate the matters primarily based on the individual facts and circumstances. For non-pattern matters, we evaluate whether there is a reasonable possibility of a material loss in excess of any accrual that can be estimated. Guarantees and indemnifications are recorded at fair value at their inception. We regularly review our performance risk under these arrangements, and in the event it becomes probable we will be required to perform under a guarantee or indemnity, the amount of probable payment is recorded.
