Start by filling in details about your vehicle purchase:

  • Vehicle Sales Price – The listed price of the car.
  • Sales Tax Rate – The tax percentage applicable in your location.
  • Title & Registration – Additional fees for registering the vehicle.

Step 2: Input Incentives, Rebates, and Financing Details

This section helps assess financing offers:

  • Loan Term – The length of your auto loan in months.

Understanding the Results

Once you’ve entered all the necessary details into our Cash Back vs. Low A.P.R. Calculator, you’ll receive a clear breakdown of both financing options. Here’s what each result means and how to interpret them:

1. Total Loan Amount

This figure represents the amount you’ll need to finance after considering the vehicle price, sales tax, title and registration fees, trade-in value, and any down payment or incentives. If you choose the cash-back option, the amount will be lower because the rebate is applied upfront.

2. Monthly Payment

The calculator will display your estimated monthly payment for both financing scenarios. A lower A.P.R. usually results in smaller interest payments over time, whereas the cash-back option reduces your initial loan amount but may have a higher interest rate.

3. Total Cost Over the Loan Term

This is the total amount you’ll pay over the loan’s entire life, including principal and interest. The best option will be the one that costs you the least over time.

4. Total Savings Comparison

The calculator will highlight which option saves you more money and how much. If the total savings favor the low A.P.R. option, you’ll pay less interest over the loan term. If the cash-back option wins, the rebate reduces your loan enough to offset the higher interest rate.

5. Best Financing Choice

At the bottom of the results, the calculator will recommend the better deal based on your specific numbers. Whether it’s cash back or low A.P.R., you’ll know exactly which option puts more money back in your pocket.

Understanding these results will help you confidently choose the financing strategy that best suits your budget and long-term financial goals.
