Typical auto loans use equal monthly payments of principal and interest. Provide the amount financed, annual percentage rate, and loan length in months to see an approximate payment and interest over the life of the loan. Check your contract for exact APR, rounding, and any rebates or balloon structures.
Payment uses the standard amortizing loan formula with n = integer months you enter and monthly rate APR ÷ 100 ÷ 12. If APR is 0, payment = principal ÷ n. Total paid and interest are payment × n minus principal.
This calculator uses plain decimal numbers. If a result looks wrong, check whether you used a comma instead of a dot (or vice versa) where the field expects one.
