Usually you can take either the rebate or the special APR, not both. The rebate lowers the amount you borrow; the low APR lowers the interest. Get pre-approved by your own lender first so you know your real rate.

Rebate or special financing?

Car makers often offer a choice: a cash-back rebate that lowers the price, or a low promotional APR, sometimes 0%. You usually can't have both. The calculator compares the two:

It shows the monthly payment, interest and total paid for each, and tells you which saves more.

Tips

Frequently asked questions

When is the low APR usually better?

When the rebate is small, the loan is large or long, or your own lender's rate is high.

Can I negotiate the price and still get the deal?

Yes. Negotiate the vehicle price first, then apply the rebate or special financing.

Is the rebate taxed?

Manufacturer rebates are not income, but in many states sales tax is charged on the price before the rebate.
