📌 5 Tips for the 0% APR vs Cash Back Decision
- ✓ The 0% APR "savings" equals the interest you'd pay. $2,500 cash back roughly equals the interest on a $32K @ 6.5% loan over 60 months — that's why this calculator is the only honest comparison.
- ✓ 0% APR almost always has a shorter term (typically 36–60 months). If the payment doesn't fit your budget, the cash-back offer usually wins by default.
- ✓ You can use the cash-back rebate strategically: invest it (at 7% in an index fund for 5 years ≈ $3,500), pay down high-APR debt, or boost your down payment to reduce the financed balance.
- ✓ Check the 0% APR fine print — most manufacturers require a 720+ FICO and a maximum LTV (loan-to-value). If you don't qualify, the dealer quietly bumps you to a higher rate.
- ✓ Don't combine the offers. Most manufacturers explicitly forbid stacking 0% APR with the cash-back rebate. Pick one or the other — and run the math here first.
