APR to nominal rate and the real cost of borrowing.
Open the Auto Loan & True Cost of Credit tool →We amortize the amount you finance (the price plus any fees and taxes you roll in) at your APR over the term, the same exact month-by-month schedule a lender uses. That gives your monthly payment, the total of all payments, and the true cost of credit, every dollar of interest you'll pay on top of what you borrowed.
The APR is a yearly rate that's charged monthly, so it quietly compounds to a slightly higher effective annual rate, which we show too. These are your own loan terms, so there's no rule to cite, just the arithmetic.
