A 0% APR offer means you may pay no interest on the qualifying auto loan during the promotional financing period, assuming you meet the lender’s requirements and follow the agreement. These offers can reduce financing costs significantly, but they may be available only to highly qualified borrowers and certain vehicles.

A cash rebate reduces the vehicle’s purchase price instead. You may then finance the remaining amount at a regular interest rate. Depending on the numbers, accepting the rebate and taking a low-rate loan could sometimes cost less overall than choosing 0% financing.

The important thing is to compare the total purchase and financing cost, not just the headline offer. Ask the dealer for the actual vehicle price, rebate amount, loan amount, APR, term, and total payments under each option.

Run both scenarios through an auto loan calculator before deciding which offer provides the better overall value.
