FAQ

How is the monthly auto loan payment calculated?
Monthly payment = P × [r(1+r)ⁿ] / [(1+r)ⁿ – 1], where P is the loan principal, r is the monthly interest rate (annual ÷ 12), and n is the number of months. The principal is the car price minus down payment, trade-in, and rebates, plus any rolled-in taxes and fees.
Should I include taxes and fees in my auto loan?
Rolling taxes and fees into the loan means you pay interest on them for the full loan term, costing more overall. If you can afford to pay them upfront, you save on interest. Toggle the checkbox in the calculator to see both scenarios instantly.
How much does a trade-in reduce my auto loan?
A trade-in directly reduces the price before calculating the loan. If you still owe money on the trade-in, that amount is added back to the new loan. Net trade-in value = trade-in value − amount owed.
What is an amortization schedule?
It shows exactly how each payment is split between interest and principal, month by month. Early payments are mostly interest; later ones are mostly principal. Scroll through the monthly or yearly tab after calculating.
