Credit Card Rewards Optimization: Earn More on Every Purchase

The right card for each category can mean thousands more in rewards every year. Here's how to build a wallet that maximizes every swipe.

How rewards optimization works

Most people use one card for everything. But each premium card has different bonus categories — one might earn 4x on dining, another 5x on travel, another 3x on groceries. Rewards optimization means using the right card for each purchase so you're always earning the highest rate.

The difference between a random swipe and an optimized one can be 3–5x more points on the same purchase. Over a year, that adds up to hundreds — or thousands — of dollars in extra value.
