The Citi Custom Cash® Card isn’t just a really rewarding card for gas purchases. It also gives you over a year to finance a new purchase or pay down an existing balance, interest-free.
It has a unique rewards structure: Earn 5% cash back on purchases in your top eligible spend category each billing cycle, up to the first $500 spent, 1% cash back thereafter. Also, earn unlimited 1% cash back on all other purchases. Special Travel Offer: Earn an additional 4% cash back on hotels, car rentals, and attractions booked on Citi Travel℠ portal through 6/30/2026. The 5% category includes gas purchases, making a great option for a dedicated gas card.
Keep in mind, though, that you’ll only earn 1% on most other purchases. That means the Citi Custom Cash® Card is better suited to only be used for one category rather than as an everyday card.
The welcome offer and the ongoing rewards are paid out in ThankYou® points, which you can either redeem as cash or use for travel expenses. The Citi Custom Cash® Card also has a $0 annual fee.
