Rebate vs Low-APR Choice.
In plain English
The rebate vs low-APR choice is a common new-car decision where the manufacturer lets you take either a cash rebate (money off the price) or a promotional low interest rate, but never both at once. A rebate lowers the amount you borrow today; a low or 0% rate lowers the interest you pay over time. Which one saves more depends on the rebate size, the rate gap, the loan length, and whether you can finance elsewhere. The only way to know is to run both numbers, because the bigger-looking deal is not always the cheaper one.
01Why it matters
Picking the wrong side of this trade can cost hundreds or thousands, and dealers rarely run the comparison for you, so the math is on you.
02The math, step by step
Take a $30,000 car. Option A: 0% APR for 60 months, paying $30,000 total. Option B: a $3,000 rebate, financing $27,000 at an outside-lender rate. If the interest on Option B is less than $3,000, the rebate wins. If it is more, the 0% deal wins. Plug both into a loan calculator before signing.
03What this is NOT
These promos are almost always either-or by design. Taking the low APR usually means giving up the cash rebate, so you are comparing two separate paths, not stacking two discounts.
