What is the Auto Loan Calculator?
Work out your monthly car payment after down payment, trade-in and sales tax. Money decisions are easier when you can see the numbers. Our finance calculators use the same standard formulas banks and financial planners use — amortization, compound interest and present-value math — so you can compare options before you commit.
How to use the Auto Loan Calculator
- Enter your vehicle price, your down payment, your trade-in value, your sales tax and the remaining fields.
- Results update automatically as you type; you can also press Calculate.
- Read the output: monthly payment, amount financed, total interest.
- Use the 📊 chart to see the result visually, then copy or share it.
Formula and method
Worked example
With vehicle price = $32,000, down payment = $4,000, trade-in value = $0, sales tax = 7 %, apr = 6.9 %, the Auto Loan Calculator returns monthly payment: $597.36; amount financed: $30,240.00; total interest: $5,601.75.
Tips for better results
- Compare at least two scenarios (for example, a 15- vs 30-year term) before deciding.
- Small rate differences compound: a 0.5% lower rate can save thousands over a long loan.
- Results are estimates; your lender’s fees, taxes and exact day-count rules may change the final figure.
