Category Cashback Cards

The plain answer

A category cashback card can earn more when its bonus categories match where you already spend. Common categories include groceries, dining, gas, transit, travel, and online shopping.

The higher rate is useful only if the card’s category definitions, spending limits, and fees fit your habits. Purchases outside the bonus categories usually earn a lower base rate.

How it actually works

The card issuer assigns a reward rate to each category. A card might earn 3% in an eligible category and 1% on other eligible purchases. If you spend $300 in the bonus category, you earn $9. The same amount at 1% earns $3.

The merchant’s classification code often determines whether a purchase qualifies. A grocery purchase made at a warehouse club, superstore, or delivery service may not receive the grocery rate. Some cards also cap the amount of spending eligible for bonus rewards.

What this means for you

Review several months of spending before choosing a category structure. Focus on spending you would make anyway, then estimate rewards using the card’s actual caps and base rate.

If you spend $4,000 per year in a 3% category instead of earning 2% with a flat-rate card, the extra reward is $40. That gain may be worthwhile when the card has no offsetting fee and the category is easy for you to use.

Common mistakes

• Choosing categories based on hoped-for spending instead of past spending.
• Assuming every merchant that sells the same products has the same category code.
• Forgetting bonus spending caps or enrollment requirements.
• Using a category card outside its bonus areas when another card would earn more.
• Buying extra items to reach a reward threshold.
