How the auto loan calculator works
Loan = price + sales tax − down payment − trade-in. Payment uses the standard amortization formula. The comparison chart reruns the formula for 36- to 84-month terms.
Example
Using the default inputs (Vehicle price: $35,000; Down payment: $5,000; Trade-in value: $0.00; APR: 7%; Term (months): 60; …), the calculator returns monthly payment of $636. Change any field above to see your own result and charts update instantly.

Frequently asked questions
What is a good car loan term?
Most experts suggest 60 months or less. Longer terms lower the payment but raise total interest and the risk of owing more than the car is worth.
Should I include sales tax in the loan?
You can pay it upfront or finance it. Financing raises your loan balance and interest cost.
