Missed credit card rewards: the cost nobody prices
The technique
Price the card you did not use
A statement records one card's rules applied to your spending. What the same spending would have earned elsewhere is the number that says whether the card is doing its job.
People judge a rewards card by the amount that arrives. ₹340 of cashback a month feels like a card that works. Whether it works depends on what else was available for the same swipes, and the statement cannot say.
The missed amount has three sources. Category mismatch: a flat card paying 1 percent on food orders when another card pays 3 percent there. Leakage inside your own card: a cap, an excluded category, rounding on small transactions. Redemption: points worth less than you assumed, or left to lapse.
The first is usually the largest and the one nobody measures, because it needs a second card's rules laid against your own spending. The other two sit on your own statement. This page prices all three on one household.
- Missed rewards are the difference between two sums, so you have to build both: what your card earned and what the better card in each category would have earned on the same spending
- A card can be fair and still miss money: below, the one card earns 56.98 percent of what the better pairing earns
- The answer can be zero, and then a second card only adds a fee and a bill
