How to Use This Calculator
When buying a car (or making another large financed purchase), you're often offered a choice: take a cash rebate now but finance at the standard interest rate, or skip the rebate and enjoy a very low promotional APR. This tool instantly shows you which path costs less over the full loan term.
- Purchase Price: The negotiated price of the vehicle before any incentives.
- Cash Back Amount: The cash rebate you'll receive if you choose the standard APR.
- APR with Cash Back: The standard annual percentage rate if you take the rebate.
- Low Interest APR: The promotional rate (often 0%, 0.9%, 1.9%) offered when you forgo the cash back.
- Loan Term: Number of months you'll finance.
Understanding the Math
For the Cash Back option, you finance the full purchase price at the higher standard APR and later receive the cash rebate.
Your net cost = total loan payments − cash back received.
For the Low Interest option, you finance the full purchase price at the promotional APR with no rebate.
Net cost = total loan payments.
The calculator compares the two net costs and highlights the cheaper choice.
Tips for Car Buyers
- Always negotiate the vehicle price before discussing incentives.
- If you plan to pay off the loan early, low-interest financing often wins because you save on interest immediately.
- If you have excellent credit and can invest the cash back at a higher return than the loan's interest rate, the rebate may be more attractive.
- Use this calculator before visiting the dealership — it arms you with knowledge and saves you money.
* This calculator assumes you finance 100% of the purchase price (no down payment) and keep the loan for the full term. Results are estimates; always confirm terms with your lender.
