1. Compare incremental value, not total rewards
If a free alternative would already earn some rewards, only the additional value created by the paid card should be used to recover the paid card’s annual cost.
2. Calculate break-even spending
Break-even spending is the level at which incremental rewards equal the annual ownership cost.
3. Treat fee waiver as a separate scenario
Run one scenario where the fee is paid and another where the waiver threshold is met. This makes it easier to see whether the card is still attractive if spending falls below the waiver threshold.
4. Value non-cash benefits conservatively
Airport lounge access, memberships, vouchers and milestone benefits should only be given a rupee value when the user would genuinely use them. Retail price is not always personal value.
