Enter the vehicle price, down payment, trade-in value, and interest rate to see your estimated monthly payment, total interest, and total cost β plus what that payment means as a share of your income.
This calculator estimates your monthly car payment from the vehicle price, down payment, trade-in value, sales tax, interest rate, and loan term β then shows what that payment costs as a share of your monthly income.
Beelinger takes the vehicle price, subtracts your down payment and trade-in value, then adds sales tax on the taxable amount to get your total amount financed. That amount is spread across your loan term using your interest rate to calculate the monthly payment.
A larger down payment or trade-in reduces the amount financed β and the total interest you'll pay over the life of the loan.
| Term | Effect |
|---|---|
| 36β48 months | Higher monthly payment, lowest total interest paid |
| 60 months | The most common term β a balance of payment size and total cost |
| 72β84 months | Lower monthly payment, but significantly more interest paid overall, and higher risk of owing more than the car is worth |
Amount financed = vehicle price β down payment β trade-in value + sales tax on the taxable amount. Monthly payment is calculated using the standard amortizing loan formula based on your interest rate and loan term. The income share compares your estimated payment to your monthly take-home pay; a payment under about 15% of take-home pay is a common affordability guideline, though your full budget matters more than any single ratio.

Beelinger's Money Coach can help you weigh a car payment against your full financial picture β rent, debt, savings goals, and everything else β before you sign anything.
Your car payment is based on the amount financed β vehicle price minus down payment and trade-in, plus sales tax β spread across your loan term at your interest rate using a standard amortizing loan formula.
Rates vary by credit score, loan term, and whether the car is new or used. Shorter terms and stronger credit typically get lower rates. Getting quotes from a bank or credit union before you shop is the best way to know what rate you actually qualify for.
A common guideline is 10β20% down on a new car and at least 10% on a used one. A bigger down payment lowers your monthly payment and reduces the risk of owing more than the car is worth.
No β a longer term lowers your monthly payment but increases the total interest you pay over the life of the loan, and increases the risk of being "underwater" (owing more than the car's value) for longer.
Yes, typically. Used car loans usually carry higher interest rates than new car loans, partly because used vehicles depreciate differently and carry more risk for lenders.
