Should You Optimize Rewards or Keep It Simple?
Simple captures most of the value
The first good card does the heavy lifting. Picking one card matched to your spending and using it for everything can return 2 percent or more with no ongoing effort. That single decision captures most of what a rewards strategy can deliver, which is why simplicity is a perfectly good choice. A credit card rewards calculator makes that one decision easy by ranking every card for your spending.
Optimizing adds value with diminishing returns
Each additional card and tracked category adds less than the last. A second card for your biggest bonus category can be worth real money, but the fifth card optimizing tiny purchases returns pennies for meaningful effort. The curve flattens, as described in are rewards worth the effort and how to maximize rewards.
Match the effort to you
There is no single right answer, only the right answer for how much you enjoy this. If you like optimizing, a two- or three-card setup meaningfully raises your return. If you would rather not think about it, one strong flat cash back card is genuinely fine. Use the calculator to see how close a simple setup gets you to the optimized one, then decide if the gap is worth closing.
