How to use this
Use it before card shopping
This tool works best when you want to answer a strategy question first: do you need one easy card, or is the lift from multiple cards meaningful enough to justify the extra effort?
Test whether a simple flat-rate card, a two-card combo, or a more optimized three-card setup is likely to earn more from the spending you already do.
Layered setup for groceries, travel/dining/gas, and everyday fallback.
