Auto Finance Calculator FAQ: Expert Answers to Your Car Financing Questions

We use the standard amortization formula used by banks and credit unions: M = P [ r(1 + r)^n ] / [ (1 + r)^n - 1 ], where M is the monthly payment, P is the principal loan amount, r is the monthly interest rate, and n is the number of payments. This is the same formula used by major financial institutions.
