How Our Calculations Work

Our calculators use standard mathematical formulas commonly used for installment loans, interest calculations, loan amortization, depreciation, and vehicle cost estimates.

For a typical fixed-rate loan estimate, the amount financed, annual rate, and number of monthly payments determine the payment. The schedule separates interest from principal as the balance falls. A longer term can reduce the monthly payment while increasing total interest, so compare both figures rather than choosing by payment alone.

Use the same vehicle price, down payment, and loan balance when comparing scenarios. Include financed fees in the amount borrowed, and keep upfront costs separate to avoid counting them twice. The assumptions described on each calculator take priority over this general overview.

Results depend on the information you enter. Interest rates, taxes, fees, trade-in treatment, incentives, lender policies, and other costs can vary, so the figures shown on this website should be treated as estimates rather than guaranteed amounts.
