When to use this calculator
Use this car loan calculator to estimate the monthly payment for a financed vehicle purchase. It is useful for testing price, down payment, trade-in value, interest rate and term before visiting a dealer or lender.
Formula
Amount financed = vehicle price - down payment or trade-in
- Vehicle price is the purchase price used for the estimate.
- Down payment or trade-in reduces the amount financed.
- Rate and term estimate the monthly loan payment.
Worked example
For a $42,000 vehicle with $8,000 down or trade-in, a 7% rate and 5-year term, the calculator estimates the monthly payment and loan cost.
Common mistakes
- Shopping by monthly payment while extending the term too far.
- Forgetting taxes, fees, warranty products or insurance.
- Rolling negative equity into a new vehicle loan without noticing the cost.
FAQs
Should I use vehicle price before or after taxes?
Use the amount you expect to finance. If taxes and fees are financed, include them in the price.
Does a longer term lower the payment?
Usually yes, but it can increase total interest and keep you in debt longer.
Can a larger down payment help?
Yes. It reduces the amount financed and may lower both payment and interest.
