About this calculator
The cash back vs low APR calculator compares two common car-financing offers side by side: taking a cash-back rebate up front but financing the (higher) remaining balance at the standard market APR, versus skipping the rebate to get a promotional low or 0% APR on the full purchase price. It computes the total interest paid and total cost under each path over your loan term so you can see the actual dollar difference, not just which incentive sounds bigger.
Which option wins depends heavily on the loan term, the spread between the market rate and the promotional rate, and the rebate amount — a large rebate often beats a low-APR offer on a short loan, while a steep APR gap tends to favor low APR on longer terms. Car buyers comparing dealer financing offers use this calculator to run the actual numbers before signing, since dealers rarely volunteer a side-by-side comparison.
