If you don’t want to spend time and effort tracking your spending to earn rewards, you may want a credit card that does the heavy lifting for you. The Citi Custom Cash® Card is a card that does just that.

This card offers a unique rewards structure that sets it apart from other cash back credit cards. You'll automatically earn 5% cash back on your highest spend category each billing cycle (up to the first $500 spent). This means you don't have to actively select or activate bonus categories — the card does the work for you.

For a limited time, you can earn 4% cash back on hotels, car rentals, and attractions booked on Citi Travel℠ portal (through June 2025). All other purchases earn an unlimited 1% cash back.

We took an in-depth look at the key features, benefits, and drawbacks of the Citi Custom Cash Card to help you determine if it's the right fit for you. 

Benefits and rewards

The key benefit of the Citi Custom Cash Card is its unique approach to cash back rewards. Unlike other cash back cards, the Custom Cash Card automatically adapts to your spending habits.

You don't need to activate a monthly rotating category or track your spending to align with bonus categories.

Each billing cycle, you'll earn 5% cash back on your top eligible spending category up to the first $500 spent. That means you can earn up to $25 in bonus cash back per category per billing cycle.

The eligible 5% categories cover a wide range of everyday expenses. Potential categories include:

For a limited time, you can earn 4% cash back on hotels, car rentals, and attractions booked on Citi Travel℠ portal (through 6/30/2025).

You’ll also earn an unlimited 1% cash back on all other purchases. 

This card comes with a bonus of 20,000 ThankYou Points — worth $200 — for spending $1,500 in the first six months.

Cash back can be redeemed as a statement credit, direct deposit, check, gift card, or via Amazon.com and PayPal. You can pool rewards with points earned with Citi travel cards — like the Citi Premier® Card — to book travel.

The Citi Custom Cash Card offers a 0% introductory APR on balance transfers and purchases for 15 months. This offer can be helpful if you need to make a large purchase or consolidate high-interest debt.

Even for a no-annual-fee card that offers 5% cash back and a 0% introductory APR, there are some downsides to consider.

First, the 5% cash back is capped at $500 spent per billing cycle. If you regularly spend more than $500 per month in one of the eligible categories, you may earn more rewards with a card that offers a higher or unlimited spending cap.

Additionally, the card's 5% categories, while broad, may not align with everyone's spending habits. If your biggest expenses fall outside the eligible categories, you may be better off with a card offering higher flat-rate cash back on all purchases.

While the introductory 0% APR offer is generous, paying off your balance before the promotional period ends is essential. After the high variable APR kicks in, carrying a balance on this card can negate the value of your cash back rewards.

Plus — to take advantage of the 0% APR balance transfer offer, you’ll need to initiate the transfer in the first four months or miss out. 

The Citi Custom Cash Card is an excellent choice for those who want a simple, flexible cash back card that adapts to their spending habits.

The Citi Custom cash is good for: 

To make the most of your Citi Custom Cash Card, tracking your spending across the eligible 5% cash back categories is essential. By understanding your spending patterns, you can use your card for purchases in the category where you're likely to spend the most.

You may also consider pairing your Citi Custom Cash Card with other rewards credit cards to optimize your earnings. For example, you could use the Custom Cash Card for your highest eligible spend category alongside a flat-rate cash back card like the Citi Double Cash® Card for all other purchases. 

If you're considering the Citi Custom Cash Card, it's smart to compare it with other cash back and balance transfer cards to ensure you find the best fit. Here are a few alternatives to consider:
