Rotating vs. Flat-Rate Cash Back: Which is Right for You?

What is a flat-rate cash back card?

A flat-rate card, such as the Citi Double Cash^® Card, offers a single, consistent cash back percentage on all purchases. This removes the need for strategizing which card to use and when.

Pros of a flat-rate card

• Simplicity: With a flat-rate card, you don't have to think about which card to use. It's a "set it and forget it" approach that ensures you're always earning cash back.
• Consistency: You can easily predict your rewards, as the earnings rate remains constant regardless of the spending category.
• Best for everyday spending: For purchases that don't fall into a bonus category (like at specialty stores or for bills), a flat-rate card offers a better return than the 1% most rotating cards give outside their bonus categories.

Cons of a flat-rate card

• Lower potential earnings: While consistent, a flat-rate card's rewards rate is generally lower than the bonus categories offered by rotating cards. You may miss out on higher rewards in categories where you spend a lot.

What is a rotating category cash back card?

A rotating category card, such as the Chase Freedom Flex or Discover it^® Cash Back, offers a high cash back percentage (often 5%) in specific categories that change every quarter, up to a spending cap.

Pros of a rotating category card

• High earning potential: If your spending aligns with the bonus categories, you can earn a much higher cash back rate than you would with a flat-rate card. For example, if groceries are a bonus category one quarter, you can use your rotating card to earn a higher percentage back.

• Category alignment: These cards often feature popular spending categories throughout the year, such as groceries, gas, or online shopping, allowing you to maximize rewards on your everyday expenses.
• Engaging and strategic: For those who enjoy tracking and maximizing rewards, this approach can be engaging and financially rewarding.

Cons of a rotating category card

• Requires effort: Maximizing rewards requires you to activate the bonus category each quarter and track your spending. If you forget to activate, you'll miss out on the bonus.
• Spending caps: The high cash back rate is typically limited to a quarterly spending cap. After you hit that cap, the earning rate drops significantly.
• Categories may not align: There may be quarters where the bonus categories don't align with your spending habits, leaving you to earn the card's base rate, which is usually only 1%.

How to choose the right strategy for you

Choosing between a flat-rate and a rotating category card comes down to your personal preference and spending habits. When you choose a cash back card, you are likely focused on the rewards rate, but it's also smart to understand how rewards are treated by the IRS.

• Choose a flat-rate card if: You prefer a simple, consistent, and low-effort approach to rewards.
• Choose a rotating category card if: You are a strategic spender who doesn't mind tracking bonus categories and wants to maximize your earnings.

An advanced strategy: Pairing your cash back cards

You don't have to choose one over the other. The most lucrative strategy for maximizing cash back is to pair a rotating category card with a flat-rate card.

• Use the rotating card for bonus spending: When a category that aligns with your spending comes up, use your rotating category card to earn the high bonus rate up to the quarterly cap.
• Use the flat-rate card for everything else: For all purchases that fall outside the bonus category, use your flat-rate card to ensure you're earning a consistent and elevated rate on all your spending, instead of the lower base rate of a rotating card.
