How to use the Cash Back or Low Interest Calculator
This tool compares a cash-back offer with a low-interest loan so you can see which costs less.
Open the Cash Back or Low Interest Calculator →
What you need to enter
- Vehicle price ($)
- Cash-back offer ($)
- Rate if you take cash back (%)
- Low-interest rate (%)
- Term (months)
- Down payment ($)
The formula
It computes both monthly payments using the standard loan formula, with the cash back deducted from the price in the first case.
Worked example
Using the default values in the calculator:
- Vehicle price ($): 32000
- Cash-back offer ($): 2500
- Rate if you take cash back (%): 6.5
- Low-interest rate (%): 1.9
- Term (months): 60
- Down payment ($): 2000
| Better deal | Take the low interest |
| Cash back: monthly / total | $538.07 / $32,284.14 |
| Low interest: monthly / total | $524.52 / $31,471.29 |
| You save | $812.86 |
Tips for better results
- Use your real bank rate for the cash-back option.
- Compare total cost, not the payment alone.
Common mistakes to avoid
- Assuming the low rate is always better.
- Ignoring the effect of the loan term.
