Key takeaways
- Carrying A Balance Reverses Everything
- Card rewards only build anything if the balance is cleared every month.
- Ask whether you would buy this without the points attached.
The core idea
Card rewards only build anything if the balance is cleared every month. Carry a balance and the interest charged will exceed whatever the rewards returned, so the card quietly reverses direction and starts costing you for the privilege of earning points. Rewards are a discount on spending you were already going to do, never a reason to spend.
Ask whether you would buy this without the points attached. The moment the answer is no, the reward has already been spent.
Bottom line
The goal is not to chase every headline. It is to build a repeatable decision process: understand the risk, compare the opportunity cost, and make choices that fit your time horizon.
