Card Stacking Optimizer
Enter your monthly spend and this runs all 165 possible 2- and 3-card combinations of the 10 no-annual-fee cards on this site, routing each category to the best card in the stack, and ranks every combination by projected annual rewards.
Estimates use each issuer’s headline category reward rates and assume you route every purchase to the best card in the stack. They do not account for category spending caps (for example the Amex Blue Cash Everyday $6,000/year cap), rotating-category activations, sign-up bonuses, or travel-portal booking requirements, so real-world earnings vary. Always confirm current terms on the issuer’s website.
When to Add a Third Card
Going from 1 card to 2 cards typically increases rewards by 25-40%. Going from 2 to 3 adds only another 10-15%. The complexity of managing three cards, remembering which to use for which purchase, and tracking three statements is not always worth it.
Add a third card if:
- - You spend more than $3,000/month total
- - You have a clear spending category that neither of your first two cards covers well
- - You enjoy optimization and do not mind some card-swapping
- - You want to earn on rent (Bilt) and your other two cards do not cover dining/groceries
Stick with two cards if:
- - You spend under $2,000/month
- - You sometimes forget which card to use for which purchase
- - The marginal reward from a third card is under $50/year
- - You value simplicity over the last few dollars of optimization
