How Auto Loan Amortization Works
Auto loan monthly payments are computed using standard fixed-term amortization:
Monthly Payment = P × [ r(1 + r)ⁿ ] / [ (1 + r)ⁿ − 1 ]
Financed Principal (P) = Vehicle Price − Cash Down − Net Trade Equity + Sales Tax + Dealer Fees
Financed Principal (P) = Vehicle Price − Cash Down − Net Trade Equity + Sales Tax + Dealer Fees
Net Trade-in Equity: Equal to Trade-in Value − Amount Owed on Trade. Negative equity (owing more than the car is worth) is rolled into your new loan principal, increasing your monthly payment and interest charges.
