How Fuel Cashback Calculator Works?
This tool works by subtracting the credit card cashback amount from the gas receipt total. The result is the net cost of fuel after the rebate.
Enter the gas receipt total
Type the amount charged at the pump, for example $65.
Enter the cashback percentage
Type the card's gas category rate. Many cards pay 2% to 5% on gas.
Read the net cost
The tool returns the receipt minus the cashback.
Compare cards
Run the tool with 2 card rates to see which card returns more.
Fuel Cashback Calculator Formula
The formula is Net Cost = Receipt − (Receipt × Cashback % ÷ 100).
Net Cost = Receipt − (Receipt × Cashback ÷ 100)Formula variables
- Receipt
- Total charged for fuel.
- Cashback
- Card rebate percentage on gas purchases.
Worked example
- Total Gas Receipt: $65.00
- Credit Card Cashback %: 4%
- Cashback: $65 × 0.04 = $2.60.
- Net cost: $65 − $2.60 = $62.40.
Result: $62.40 ($ net cost after rebate)
A 4% card on $2,000 of yearly fuel returns $80.00. Some cards cap the bonus rate at a quarterly or yearly spending limit, so check the card terms.
