Rewards can be worth more than a card costs when you pay purchases in full and avoid fees. Carry a balance, however, and interest and fees can quickly outweigh the points, miles, or cash back you earn. The real price of your rewards card is the value of its rewards minus its interest and fees—not the advertised rewards rate alone.
What APR tells you—and what it does not
APR is the yearly rate charged for borrowing. It is a key part of a credit card’s cost, but it is not by itself the amount you will owe: the balance, how long it remains unpaid, the type of transaction, fees, and your card’s calculation method matter too. The Consumer Financial Protection Bureau (CFPB) puts it plainly: “A credit card’s interest rate is the price you pay for borrowing money.” CFPB: What is a credit card interest rate? What does APR mean?
Many issuers calculate interest daily using an average daily balance. Your statement may show separate APRs and balances for purchases, cash advances, and balance transfers. That is why APR alone is not enough to estimate a charge: you also need the relevant balance, number of days, APR category, and issuer’s method. If interest is accruing, paying earlier can reduce the time a balance is subject to interest. CFPB: How does my credit card company calculate the amount of interest I owe?
When rewards can be worth it
If you pay your statement balance in full by the due date and retain your purchase grace period, you can generally avoid interest on purchases. In that case, a rewards card may deliver value, provided the rewards you can realistically use exceed any annual fee and other costs. Evaluate rewards based on how you actually redeem them, not a headline rate that assumes an ideal redemption.

A grace period is the time between the end of a billing cycle and the payment due date. Issuers are not required to offer one, although most cards provide one for purchases. Check your agreement for the terms that apply to your account. CFPB: What is a grace period for a credit card?
Why carrying a balance changes the calculation
Rewards are not a return on spending if that spending creates debt. Once you carry a balance, compare the value of rewards earned with the interest and fees incurred. The CFPB’s 2023 Consumer Credit Card Market Report says that when a consumer revolves a balance, “the cost of interest and fees almost always exceeds the value of rewards the consumer may have earned.” That is a population-level finding, not a guarantee about every card or person.

Purchase grace-period rules can make a difference: if you do not pay the balance in full, you may lose the grace period, and new purchases can begin accruing interest from their transaction dates. Cash advances generally accrue interest from the transaction date as well. Balance transfers and other transaction types may have their own APRs and fees. CFPB grace-period guidance

How to compare cards by their real cost
Compare the terms that determine borrowing cost as well as the benefits advertised by the card. Your agreement and statement are the authority for your account; terms can differ between issuers and transaction types.
Rank #4
- Purchase APR: Check whether it is fixed or variable and the rate that applies after any introductory period.
- Other APRs and fees: Compare cash-advance and balance-transfer APRs, plus transaction fees. Cash advances can start accruing interest immediately.
- Promotional offers: Note how long an introductory rate lasts and what rate applies afterward.
- Grace-period eligibility: Confirm what you must pay, and by when, to avoid purchase interest.
- Rewards and annual fee: Estimate the rewards you will actually redeem, then subtract annual and other applicable fees.
- Payment habits: If you expect to carry debt, weigh the applicable APR and a realistic repayment plan more heavily than headline rewards.

Prioritize reducing borrowing costs rather than earning more rewards. CFPB guidance recommends shopping for a lower APR, avoiding high-APR transactions such as cash advances, paying on time and more than the minimum, and paying earlier when possible. A lower-rate option may still have fees or conditions, so compare the full terms rather than the rate alone. CFPB: What is a credit card interest rate? What does APR mean?

Check your statement and agreement for how payments are allocated. Different balances can have different APRs; amounts paid above the minimum generally go first to the highest-rate balance. A missed minimum payment can trigger a fee or affect a promotional APR under the agreement’s terms. Do not assume every issuer handles every balance or promotion identically.
