Car Loan Calculator
Estimate your monthly auto loan payment before you visit the dealership. Enter the vehicle price, down payment, interest rate, and loan term to see your payment, total interest, and overall cost.
An auto loan is an installment loan used to purchase a vehicle. Like mortgages, car loans use the standard amortization formula to calculate fixed monthly payments. The monthly payment depends on the loan amount (vehicle price plus tax minus down payment), interest rate, and loan term.
The formula is: M = P[r(1+r)^n] / [(1+r)^n - 1], where P is the principal (loan amount), r is the monthly interest rate, and n is the number of monthly payments. A larger down payment or shorter loan term will reduce total interest costs significantly.
Financial experts recommend keeping your total car costs (payment, insurance, gas, maintenance) below 15-20% of your take-home pay. Shorter loan terms (36-48 months) typically have lower interest rates and much less total interest than 72-84 month loans. A longer term may offer a lower monthly payment, but you risk owing more than the car is worth (being "upside down" on the loan).
