THE BIG PICTURE · 3 min read

Is 3% cash back actually better than 2%?

Sometimes. A card earning 3% in selected categories and 1% elsewhere beats a flat 2% card only when more than half of your eligible spending earns that 3% rate, assuming no caps or fees.

The headline rate is only part of the story.

Imagine two hypothetical cards. One earns 2% everywhere. The other earns 3% on a few categories and 1% elsewhere. Neither charges an annual fee. Your total monthly spending is $2,000.

Spending mixFlat 2%3% / 1% card
$500 bonus / $1,500 other$40$30
$1,000 bonus / $1,000 other$40$40
$1,500 bonus / $500 other$40$50

The category card wins in the last row, ties in the middle, and loses in the first. Nothing about the cards changed. Your spending mix did.

Find your break-even point.

Let b be the share of spending that earns the bonus. The category card returns 3% × b + 1% × (1 − b). Set that equal to 2%, and b = 50%.

For a hypothetical 3% / 1.5% card, the break-even share falls to one third. A stronger base rate matters when a large share of purchases sits outside bonus categories.

Then add the real-world details.

Spending caps, excluded merchants, and redemption choices can change the answer. Our calculator applies the modeled caps and shows a blended return across your whole budget. Two cards with the same estimate can still differ in acceptance, fees on foreign purchases, or benefits we do not value.

Use purchases you already plan to make. Increasing spending to chase rewards defeats the purpose. These examples assume eligible purchases, full payment, and no interest or other fees.
