- A reward rate applies to eligible spending; APR applies to a balance over time.
- Annual fees, interest, and purchases made only to earn rewards can outweigh the benefit.
- Compare rewards you can realistically redeem, using the same spending and repayment assumptions.
All monetary examples use hypothetical currency units. Use the same currency throughout a calculation; the amounts are not local price or income benchmarks.
Credit card rewards are worth what can actually be redeemed, after the costs of earning them. A card promising more points can produce a smaller net benefit if it charges a higher annual fee, adds interest, or encourages purchases that would otherwise not happen.
The examples below use assumed currency-unit amounts and invented product terms to explain the arithmetic. They are not live card offers, rankings, or recommendations. Account terms and local rules must be checked separately.
Who pays for the rewards?
Rewards are a cost to issuers and an incentive to attract and retain customers. The CFPB’s May 2024 rewards report describes issuers reporting interchange revenue net of rewards expense, with other funding channels including annual fees and merchant-funded offers. Promotional bonuses can be evaluated against revenue an account produces over time.
That is broader than a claim that every reward is funded by somebody else’s interest bill. Funding varies across programs, and an issuer’s economics do not determine whether a particular household receives a net benefit.
Start with a realistic annual value
Use spending that would happen anyway, only in eligible categories. A simple comparison is:
Net annual value = realistically redeemed rewards and useful benefits − annual fee − interest − other account costs − spending induced solely by the reward.
Avoid counting a benefit at its advertised retail value if it replaces nothing you would actually pay for. Treat a one-time sign-up bonus separately from recurring benefits so the first year does not stand in for every later year.
Suppose two hypothetical cards apply a flat cash-back rate to the same 12,000 of annual eligible spending. Assume full repayment within the applicable grace period, no interest, no other fees, and full cash redemption.
| Assumed terms | Card A | Card B |
|---|---|---|
| Cash-back rate | 1% | 2% |
| Annual fee | 0 | 95 |
| Rewards on 12,000 | 120 | 240 |
| Net value after annual fee | 120 | 145 |
Card B’s higher rate delivers 25 more net value under these assumptions. Its extra 1% earns enough to cover the 95 fee at 9,500 of annual eligible spending: 95 / 0.01. That is a comparison with Card A, not just the point where Card B’s rewards cover its own fee. Different categories, caps, fees, or redemption values change the answer.
Why interest can outweigh cash back
A reward percentage and an APR use different denominators and periods. Earning 2% on a 1,000 purchase produces 20 once. Interest accrues on the interest-bearing balance for as long as it remains outstanding.
For a simplified illustration, assume a 1,000 balance is subject to a 24% annual rate for a month, with no payment, fees, or new spending during that period. A monthly approximation gives 1,000 × 0.24 / 12 = 20 of interest. One month’s interest matches the one-time reward in this example.
The CFPB explains that many issuers use daily balances. Actual charges depend on the account terms and transaction dates; the approximation does not reproduce a statement.
The grace-period guide also explains why repayment matters. Where a purchase grace period applies, paying the required balance in full by the due date can avoid purchase interest. Carrying a balance can remove that protection. Cash advances may be treated differently.
Earning points is different from redeeming value
The CFPB’s 2024 report identified complaints about unexpected promotional conditions, devaluation, redemption problems, and lost rewards. Complaints illustrate possible problems, rather than measuring every customer’s experience.
Useful comparison questions include: which purchases qualify, whether an earning cap applies, what redemption options exist, whether a bonus has a deadline, and what happens after a return or account closure. The current agreement matters more than a generic point valuation.
A hypothetical 200 bonus is not 200 of extra wealth if obtaining it requires 300 of otherwise unwanted purchases with no value to the buyer. Where purchases provide some genuine benefit, that benefit needs a realistic valuation rather than being assumed either worthless or fully equivalent to cash.
Compare the repayment path as well as the reward
Our credit-card payoff calculator illustrates the effect of payments on a balance using a monthly interest approximation. It assumes no fees or new spending and does not model points or multiple APR categories. The credit-card interest guide explains those limits.
Use the same planned spending, redemption assumptions, and repayment pattern for each comparison. A cash-flow plan can show whether those purchases and repayments fit the calendar. The reward is one part of the result; the cash actually retained after costs is the more useful number.
