- Category caps, exclusions and redemption values often halve the headline rate.
- Interest on a carried balance overwhelms any realistic rewards rate.
- Administrative time is usually worth more than the rewards difference.
- Calculate the blended rate on your own spend mix, not the advertised one.
- Redemption flexibility matters as much as the earn rate.
Why headline rates mislead
An advertised rate normally applies to selected categories, up to a cap, subject to exclusions, and at a redemption value that may be lower than the nominal one. Each qualification reduces the effective rate, and they compound.
The number that matters is the blended rate across your actual spending pattern, after caps and at realistic redemption values.
Structural features that reduce the real rate
| Feature | Effect |
|---|---|
| Category caps | The bonus rate stops applying after a spend threshold |
| Category definitions | Merchant coding decides eligibility, and it is frequently unintuitive |
| Exclusions | Tax payments, cash-like transactions and some vendors often earn nothing |
| Redemption value | Points may be worth less than face value depending on redemption route |
| Expiry | Unredeemed rewards can lapse, particularly on account closure |
| Annual fee | A fixed cost that must be recovered before rewards are net positive |
The calculation worth doing
Take last year's card spend, split it by the categories the programme actually recognises, apply the rates with caps, and value the rewards at what you would realistically redeem them for. Then subtract the annual fee.
In most companies the difference between two competitive programmes lands within a rounding error of the finance time that either one saves or costs.
- Use twelve months of real spend, not a projection.
- Apply caps month by month — annual figures hide when caps bite.
- Value points at your realistic redemption route, not the best-case one.
- Subtract fees, then compare against administrative time saved.
Interest dominates everything
If a balance is carried, interest almost always exceeds rewards earned by a wide margin. A programme optimised for rewards while carrying a balance is optimising the smaller number.
The first question is therefore not which programme pays more, but whether the company will carry a balance at all.
Frequently asked questions
Treatment varies by jurisdiction and by whether the reward is characterised as a rebate or as income. Ask your accountant rather than assuming — the answer differs between countries and sometimes between reward types.
Only if you will actually redeem them at a favourable rate. Cashback is simpler to value and harder to lose; points can be worth more but require effort and carry expiry risk.
Rarely. Liability, controls and administrative time typically move the total outcome far more than the rewards differential between competitive programmes.
