Hold spending constant
Use one annual spending number and one category mix for both cards. A points card that “wins” only because you imagined more travel than you take is not a comparison. If a category bonus is capped, apply the bonus only to the dollars that fit under the cap.
Value points at a redemption you control
Cash back is usually worth one cent per dollar of rewards after it posts. Points need a redemption: statement credit, transfer, or booking. Use a rate you have received or can get without hunting a rare award. Then subtract friction—expired points, unused credits, and the time you will not spend optimizing transfers.
- Statement-credit value, if available
- Typical transfer or booking value you can repeat
- Share of points you historically leave unused
- Annual fee on each card
Price the complexity
A simple 2% cash-back card asks less of you. A points card can beat it when you already book the travel the program rewards. It loses when award space is thin, when you redeem for gift cards at a poor rate, or when the fee buys credits you skip. Complexity is a cost if it causes unused value.
Separate year-one bonuses from the steady state
A large welcome bonus can make a points card look unbeatable in month one and ordinary in month thirteen. Compare first-year value and ongoing value as two rows. If you would not keep the card after the bonus, include the cost of closing or product-changing it.
Interest still ends the argument
Neither cash back nor points is a reason to revolve a balance. If APR differs and you might carry debt, compare interest first. Then put the same spend and a conservative point value into the cash-back-versus-points calculator so the result is tied to your numbers.
Common questions
Is cash back better than travel points?
Cash back is easier to value. Points can win when you reliably redeem them above a conservative rate after fees. Compare both with the same spending and a redemption you can repeat.
What point value should I use?
Use a rate tied to a redemption you can actually complete, often near one cent if you take statement credit, or a modest premium only if you regularly book that travel.
Should a welcome bonus decide the card forever?
No. Score the first year and the ongoing year separately so a one-time bonus does not hide a weak long-term rate or an unused annual fee.
