Why use a car loan with trade-in calculator

Use this free tool to see your real monthly payment after applying your trade-in and down payment. Many buyers focus on the new car price—this shows what you actually finance and pay. Compare with our car loan calculator or used car loan calculator if you already know the financed amount.

Know your payment before you negotiate

Enter the out-the-door price, your trade-in value, and any cash down. At $32,000 car − $8,000 trade − $2,000 down = $22,000 financed at 6.5% for 60 months ≈ $430/month. Use our down payment calculator for down-payment-only scenarios.

Handle negative equity correctly

If you owe more than your trade is worth, add that amount to the car price or subtract from trade. The calculator shows the payment for whatever amount you finance. See our interest calculator for total cost breakdowns.

How to use this car loan with trade-in calculator

Enter the new car price — The total out-the-door price including tax, tags, and fees (or the amount you’re financing if different).

Enter your trade-in value — What the dealer offers, or an estimate from Kelley Blue Book or similar. If you owe on the trade, subtract the payoff from the value.

Enter cash down payment — Any additional cash you’re putting down (use 0 if trade-in is your only “down” amount).

Enter rate and term — Your lender’s APR and loan term in months.

Click Calculate — See the amount financed (price − trade-in − down) and your monthly payment.

Example: $32,000 car with $8,000 trade-in and $2,000 down

You buy a car for $32,000, trade in your old car for $8,000, and put $2,000 cash down. You finance $22,000 at 6.5% for 60 months. Your monthly payment is about $430. Over five years you’d pay roughly $25,800 in total—$3,800 in interest. Without the trade-in and down payment, you’d finance $32,000 and pay about $626/month. Use the calculator above to try your own numbers.

Getting the most from your trade-in

Check your trade-in value on Kelley Blue Book, NADA, or Edmunds before you visit the dealer. If you owe more than the trade is worth (negative equity), that amount gets rolled into the new loan—use a lower trade-in value or add the payoff to the car price in the calculator. A larger trade-in or down payment reduces the amount financed, your monthly payment, and total interest.

Compare with our loan calculator with down payment for down-payment-only scenarios, or the standard car loan calculator if you already know the financed amount.

Frequently asked questions

What if I owe more than my trade-in is worth?

That’s negative equity. The amount you owe gets added to the new loan. Enter the new car price plus the negative equity, and use 0 for trade-in. Or enter the net trade (value minus payoff) if it’s positive.

Should I use the dealer’s trade-in offer?

You can. Get a few offers—dealer, CarMax, online buyers—and use the best estimate. The calculator shows the payment for whatever trade value you enter.

Does the car price include tax and fees?

Use the total amount you’re financing. If tax and fees are rolled into the loan, include them in the car price. If paid separately, use the vehicle price only.

Can I use this for a used car?

Yes. Enter the purchase price, any trade-in, and down payment. Used car rates are often higher—enter the rate your lender quotes. See our used car loan calculator for rate comparisons.

What if my trade-in value changes?

Use your best estimate—dealer, CarMax, or KBB. The calculator shows the payment for whatever value you enter. Update it when you get a firm offer.
