How Much Can You Actually Save?
The average American spends about $200 per month on gas at current prices. With a 5 percent cashback card, that translates to $10 per month or $120 per year in savings. For households with two drivers, savings can reach $240 or more annually.
Tips for Maximizing Gas Rewards
- Pay at the pump to ensure the transaction codes as a gas station purchase
- Avoid buying non-fuel items inside — convenience store purchases may not earn the gas rate
- Stack gas card rewards with loyalty programs from shell, BP, or ExxonMobil
- Pay your balance in full each month to avoid interest charges that erase your savings
