Category Optimizer Calculator

Bonus-category cards pay more on specific spending like dining or groceries — calculate the real annual gain from using the right card for each category instead of one flat-rate card.

Quick answer: Bonus-category cards pay more on specific spending like dining or groceries — calculate the real annual gain from matching cards to categories instead of one flat-rate card. Enter Monthly Dining Spend, Monthly Groceries Spend, Monthly Gas Spend, and Monthly Other Spend to personalize the estimate. It returns Optimized Monthly Rewards, Current Monthly Rewards (One Flat Card), and Monthly Gain From Optimizing so you can compare the impact before choosing a next step.
