Auto loan & lease
payment calculator

Start with the amount financed: negotiated price plus financed tax and fees, minus cash down and net trade-in equity. A fixed monthly amortization calculation uses that amount, the annual interest rate divided by 12, and the number of payments. At 0% interest, principal is divided across the term. This tool rounds each month to cents and adjusts the final payment. Official guidance ↗

Use the contract interest rate for the closest payment estimate. APR includes interest and certain finance charges, so entering APR as the interest rate can produce a different monthly payment. Use the actual financed amount and fees from your offer. This tool does not reconstruct a lender’s legally disclosed APR. Official guidance ↗

Extending repayment spreads the principal across more months. With a positive interest rate, the balance remains outstanding longer and usually produces more total interest. Try the term buttons and compare the interest total and balance chart, as well as the monthly payment. Official guidance ↗

This estimate adds monthly depreciation and rent charges, then tax on that base payment at your entered rate. Depreciation uses adjusted lease cost minus contract residual, divided by the lease term. The rent charge uses adjusted cost plus residual, multiplied by the money factor. Actual contracts and rounding can differ. Official guidance ↗

A money factor is a decimal used in a lease rent-charge calculation. Enter 0.002 as 0.002, not 2. Ask the lessor for the quoted factor. It is not the same as an APR disclosure, and changing it here does not predict the rate a lender will offer. Official guidance ↗

Residual is the lease contract’s stated value at the end of its term. If the quote gives 60% of a $38,000 MSRP, the residual is $22,800. The residual is used to calculate the lease and may serve as its purchase-option price before added fees and taxes. It is separate from your own estimate of future market value. Official guidance ↗

Compare cash paid over the same 36 months, then account for what remains: the financed vehicle and outstanding loan, versus a returned leased vehicle. This tool shows that remaining balance and optional estimated equity. Full-loan cash paid is labeled separately. It does not assume a second lease or declare a winner from payments alone. Official guidance ↗

It spreads all entered lease-return spending across the term: cash down, upfront fees, every monthly payment, the return fee and estimated excess-mileage charges. For example, $3,000 down plus 36 payments of $400 averages $483.33 a month before any additional charges. It is a comparison measure, not the contractual payment. Official guidance ↗

Yes. Here it equals cash down plus other entered upfront charges plus the first monthly payment. The full lease total counts that first payment once. Exclude it from the “Other charges paid at signing” field. Refundable security deposits are outside this model; do not enter a refundable deposit as a permanent cost. Official guidance ↗

Enter the trade-in offer and the amount still owed separately. Their difference is net equity. Positive equity reduces the new financed or capitalized amount; negative equity increases it in this scenario. The offer must actually allow that treatment. Trade-in value is an asset contribution, so it is listed separately from cash paid. Official guidance ↗

It uses the tax amounts and payment-tax rate you supply. It does not determine state or local rates, trade-in credits or exemptions. Enter quoted loan tax as financed or upfront. For leases, use monthly payment tax only when that matches your quote; put other quoted tax in either financed or upfront charges, once. Official guidance ↗

Expected miles above the annual allowance are multiplied by the lease term in years and the quoted per-mile charge. The estimated charge is added at return. Zero means no estimated overage under those inputs, not unlimited mileage. A change in allowance can also change a real lease’s residual or price; update the entire quote when needed. Official guidance ↗

No. Lease spending assumes you return the car at term end. The contract residual is shown as a possible buyout price before any purchase-option fee, tax, registration or financing. A buyout needs a separate complete offer; do not add the residual to a lease-return total and treat it as a complete ownership comparison. Official guidance ↗

Fuel, electricity, insurance, maintenance, depreciation forecasts, early termination, excess wear, refundable deposits, unentered taxes and fees, and proceeds from a future sale are excluded. Explore the vehicle expense calculator for running costs. Missing amounts are not automatically estimated. Official guidance ↗
