How to build a credit card stack that actually earns (2026)
Build around your top three spend categories: pick the best earner for each, then add a flat 2% catch-all for everything else. Cap at four cards until you can route reliably between them.
Quick comparison
| Card | Best for | Earn rate | Annual fee |
|---|---|---|---|
| Category card #1 | Largest spend category | 4–6% | Varies |
| Category card #2 | Second category | 3–5% | Varies |
| Citi Double Cash | Catch-all | 2% | $0 |
Why most people pick the wrong card
Most people default to the same card at checkout — usually the one on top in their wallet. That habit quietly costs hundreds of dollars a year when another card in your stack earns 3×, 4×, or even 6× on the same purchase.
How Pikt routes smarter than guesswork
Pikt links the cards you already carry, weighs your offers and category earn rates, and tells you the best card to use — with a plain-English explanation and dollar estimate for every purchase. Online, the Pikt Checkout extension auto-fills that card at checkout; in-store, Pikt Nearby names it on your lock screen. Pikt's quiz identifies your top categories and recommends catalog earners to anchor your stack.

- How long should I wait between card applications?
- Issuer rules vary — Chase 5/24 is the most common constraint. Build slowly and route well before adding more.
