Calculate the value.
Ignore the sales pitch.
A large bonus can still be a bad deal if it causes extra spending, interest, or an annual fee you cannot recover. Put your own numbers into the offer.

Decode the language on the application page.
APR, intro rates, statement credits, and transfer fees are defined by what they change in the bill—not by how impressive they sound.
Open the credit-card glossary →- APR
- Annual percentage rate is the yearly cost of carrying a balance, stated as a percentage. A purchase APR, cash-advance APR, and penalty APR can differ on the same card. APR is not a ranking of rewards value and does not tell you whether you will be approved.
- Promotional / intro APR
- A temporary rate for purchases, balance transfers, or both. The useful facts are the rate, the start and end rules, which balances it covers, and the rate that applies afterward. An intro APR is not a promise that remaining debt stays cheap if you miss a payment or add new charges.
- Grace period
- The time between the end of a billing cycle and the payment due date during which new purchases may avoid interest if you pay the statement balance as required. Carrying a balance, using cash advances, or missing the issuer’s conditions can remove that treatment. A grace period is not extra time to spend without tracking the due date.
- Annual fee
- A yearly charge for keeping the card, often billed on the first statement and at each anniversary. Credits, lounge access, or bonus categories do not automatically offset it. Compare only benefits you will use against a realistic no-fee alternative.
The rule that matters
Rewards do not beat interest.
- If you expect to carry a balance, compare debt cost before rewards.
- Do not create spending solely to earn a bonus.
- Value credits at what they replace—not their advertised face value.
- Confirm current APRs, fees, eligibility, and deadlines directly with the issuer.
