Auto Calculators

Price a vehicle the smart way: loan payments, rebates versus low-interest financing, leasing and early payoff.

How you finance a car can cost or save thousands on the same vehicle. These tools break a deal into its real parts — the amount financed, the rate, the term, and the trade-offs behind rebates, leasing and refinancing — so you negotiate the financing as hard as the price.

Estimate the payment first, then settle the specific question: take the rebate or the low rate, lease or buy, and whether refinancing an existing loan is worth it.

Calculator FAQ
Are these car loan calculators free?

Yes — every calculator here is free to use with no sign-up. Run as many scenarios as you like to compare terms, rates and down payments before you ever visit a dealer.

Do the calculators account for a trade-in and sales tax?

The car loan calculator lets you enter a down payment and trade-in value, which reduce the amount financed. Sales tax varies by state and is often rolled into the loan, so add it to the price if your dealer does.

Should I get pre-approved before using these?

It helps. Knowing a real rate from your bank or credit union makes the estimates accurate and gives you leverage at the dealership. Use the calculators to set a target payment first, then shop the financing.
