What APR Really Means
APR stands for annual percentage rate — the yearly interest rate you pay on a balance you carry from month to month. If you pay your statement balance in full by the due date, the APR may never touch your purchases. The number that matters is not just the rate in the headline but the rate that applies after any promotional period ends.
Most offers contain more than one APR. There is usually a purchase APR for everyday spending, a separate APR for balance transfers, and sometimes a penalty APR that can kick in after a late payment. A teaser or introductory rate is a temporary number that eventually reverts to the ongoing rate. A teaser that looks like a gift lasts only for a limited window; after that window closes, the ongoing rate applies to whatever balance remains. To compare offers fairly, list each APR type side by side: the intro rate, the ongoing rate, and the conditions that switch you from one to the other.
How Interest Adds Up on a Carried Balance
Interest on credit cards is typically calculated daily on the balance you carry. A balance you do not pay off keeps accruing interest day after day, and paying only the minimum lets the balance — and the interest on it — keep growing. The exact math depends on the issuer's billing method and your approved rate, so no generic example can substitute for the terms in your own offer.
Grace Periods: When the Interest Clock Starts
A grace period is the window between the end of a billing cycle and your payment due date. If the offer includes one and you pay the full statement balance, new purchases may not accrue interest. But grace periods often do not apply to cash advances or balance transfers, which can start accruing interest immediately. The offer should state when interest begins for each transaction type. If that line is missing or vague, question it.
Fees Beyond the APR
APR is not the only cost. Common fee categories include an annual fee for keeping the card open, a balance transfer fee when you move a balance from another card, a foreign transaction fee for purchases made abroad, and a late payment fee. Exact amounts vary by issuer and by your agreement, so verify every figure in the issuer's official terms rather than trusting a summary line.
Where the Real Terms Live
Every serious offer includes a required summary of rates and fees — often the densest page in the mailing. Look for the section that lists APRs, the grace period, fees, and transaction charges. Read the version tied to the specific card and offer date, because terms change over time. Promotional phrases like "0% intro APR" or "no annual fee" mean little until you read them against the actual terms.
Promises You Should Never Trust
Some offers promise more than any offer can deliver. Watch for wording like "guaranteed approval," "no credit check," or "cash now." Approval depends on the issuer and your credit profile; no publisher, advertiser, or third party can promise an outcome. When an offer leans on promises instead of terms, treat that as a warning sign, not a benefit.
The table below separates explaining a term from promising an outcome.
| Content type | Example phrasing | Policy treatment | Ad-serving expectation |
|---|
| Educational explanation of credit card terms (APR, fees, grace period) | "APR is the yearly interest rate charged on a balance you carry." | Credit-related content is classified under Google Publisher Restrictions; it is allowed but may receive fewer ads. | May serve fewer ads than unrestricted content |
| Publisher promise about an outcome outside its control | "Get approved with no credit check." or "Open this card and get cash now." | Classified as an egregious violation ("promising loans," specific promises outside publisher control such as a "no credit check" claim); 1 egregious violation = 1 strike. | High risk of policy strike and loss of ad serving |
The difference matters for two reasons. First, an explanation of a term is something an offer can stand behind, while a promise of approval is not, because approval depends on the issuer and the applicant's credit profile. Second, advertising platforms treat approval and cash promises as deceptive claims — a useful signal that an offer relying on promises rather than terms deserves extra scrutiny.
A Five-Point Checklist Before You Apply
Before you submit an application, run through five checks:
- APR types. Identify the purchase APR, any intro APR and its expiration date, the balance transfer APR, and any penalty APR conditions. Compare the same lines across every offer.
- Grace period. Confirm how many days you have to pay in full before interest starts, and whether that protection covers purchases only.
- Fees. Find the annual fee, balance transfer fee, foreign transaction fee, and late fee amounts in the official terms, not in a headline.
- Triggers and limits. Note what moves you to a higher rate, such as a late payment, and any conditions attached to credit limits or promotional periods.
- Terms source. Read the rate-and-fee summary in the actual offer. If it is missing, ask the issuer for current terms in writing before applying.
The Bottom Line
Treat any offer as a draft until the rate-and-fee summary confirms the details. "Pre-qualified" does not mean approved: a formal application may involve a credit check and can still end in denial, and the rate you receive depends on your credit profile.

APR, fees, grace periods, and promotional terms vary by issuer and change over time, so verify current terms with the issuer and consider consulting a qualified financial professional before you decide.
