Cash Back Rebate vs. Low Interest Financing: Which is Better?
When buying a new car or large appliance, dealers often present a tricky choice: Take a cash back rebate (which lowers the purchase price), or choose a promotional low-interest rate (like 0% or 1.9% APR).
Our Cash Back vs. Low Interest Calculator effortlessly runs the math for both scenarios, factoring in your down payment, trade-in, and loan term to tell you exactly which option leaves more money in your pocket.
How to Make the Choice
Choosing the right financing option usually comes down to three factors:
- The Size of the Loan: The more you borrow, the more interest you pay. For expensive vehicles, 0% financing often saves more than a flat $2,000 rebate.
- The Size of the Rebate: A massive cash-back offer on an affordable car usually outweighs the interest savings.
- Your Standard Interest Rate: If you have average credit and your standard bank loan rate is 8%, the dealer's 0% financing offer is highly valuable. If you can get a 3% rate from your credit union, the cash-back rebate might be the better deal.
