Estimate the vehicle price that may fit your monthly payment budget.

Start with the monthly auto payment you want to stay near, then add your interest rate, loan term, down payment, trade-in, taxes and fees to estimate a vehicle price that may fit those assumptions.

Understanding Vehicle Affordability

How a monthly budget translates into a vehicle price

Instead of starting with a vehicle price, this calculator works backward from the monthly loan payment you enter.

It estimates how much can be financed at the selected interest rate and loan term, then accounts for down payment, trade equity, sales tax, rebates and financed fees to estimate a vehicle purchase price.

Interest rate

A higher interest rate means more of each payment goes toward financing cost, leaving less room for vehicle principal at the same monthly budget.

Loan term

Extending the loan term can increase the vehicle price that fits a given monthly payment because the balance is spread across more payments. However, longer terms may increase total interest.

Down payment and trade-in

Cash down and positive trade equity reduce the amount that must be financed. This can allow a higher vehicle purchase price while keeping the monthly payment near the same target.

Negative equity

If you owe more on your trade-in than it is worth, that negative equity may be added to the new loan. This can reduce the vehicle price that fits your target payment.

What this calculator considers

Vehicle-price estimate is solved from the target payment after accounting for APR, term, tax, fees, down payment, trade equity and rebates.
✓ Target monthly principal-and-interest payment
✓ Interest rate and loan term
✓ Cash down payment
✓ Trade-in value and trade loan balance
✓ Cash rebates and incentives
✓ Sales tax and trade-in tax treatment
✓ Financed dealer and registration fees
✓ Estimated total loan interest

This estimates a vehicle price from the financing assumptions entered. It does not evaluate household income, insurance, fuel, maintenance or whether a particular payment is appropriate for your personal budget.

Auto Affordability Calculator FAQ

Frequently asked questions

How does this calculator estimate an affordable vehicle price?

It first determines approximately how much loan principal can be supported by the target monthly payment, APR and loan term. It then accounts for estimated tax, fees, down payment, trade equity and rebates to estimate the vehicle purchase price.

Does a longer loan term increase the vehicle price estimate?

Usually, yes. More repayment months generally allow a larger loan balance at the same monthly payment. However, longer terms can also increase total interest and keep the loan outstanding longer.

How does a higher interest rate affect affordability?

A higher APR generally reduces the amount of principal that can be financed at the same monthly payment, which can lower the estimated vehicle price.

How does negative trade equity affect the result?

If the amount owed on your trade exceeds the vehicle's trade-in value, the difference may need to be paid separately or added to the new loan. Rolling it into the new loan can reduce the new vehicle price that fits within the same monthly payment.

Does the calculator include sales tax?

Yes. Enter an estimated sales tax rate and select whether trade-in value reduces the taxable purchase price. Actual tax treatment varies by jurisdiction.

Does this tell me what car I should buy?

No. It estimates a vehicle price based on financing assumptions only. Your overall transportation budget may also include insurance, fuel, maintenance, repairs, parking and other expenses.

Why could the dealer's affordability estimate differ?

Dealer or lender calculations may use different interest rates, taxes, fees, rebates, add-on products, trade-in values and financing terms.
