AI insight
Promotional APRs are temporary low rates that apply to balance transfers or new purchases for a set period. Purchase APR is the ongoing rate for everyday spending after any promo ends. Penalty APR can be triggered by late payments or exceeding your limit, often jumping to a much higher rate.
- Promotional APRs are limited-time offers that revert to the purchase APR when the period ends.
- Purchase APR is the standard rate applied to new purchases and any balance after the promo expires.
- Penalty APRs are imposed for missed payments or limit breaches and can stay in effect for months.
- Comparing all three rates before you apply helps you avoid surprise interest charges while rebuilding credit.
What is a promotional APR?
A promotional APR (often called an intro APR) is a reduced interest rate that a card issuer offers for a limited window — typically 6 to 18 months — on balance transfers, new purchases, or both. During this window you pay little or no interest on the qualifying balances, which can be a useful tool when you’re consolidating debt or financing a large purchase.
The promotional period and the rate are disclosed in the Schumer box on the card’s terms page, and the CFPB requires issuers to state the exact length and the rate that will apply after the promo ends. You can compare current promo offers on our credit‑cards hub to see which cards match your timeline.
Understanding purchase APR
The purchase APR is the standard variable rate that applies to any new purchase once the promotional period expires — or immediately if the card has no intro offer. It is expressed as an annual percentage rate and fluctuates with the prime rate, so the exact cost can change month to month.
Because the purchase APR determines the interest you accrue on everyday spending, it’s the figure you’ll see most often on your monthly statement. If you carry a balance, the purchase APR compounds daily, making it the primary driver of long‑term credit‑card cost.
Penalty APR triggers and consequences
A penalty APR (sometimes called a default APR) is a higher rate that issuers may impose when you miss a payment, pay less than the minimum, or exceed your credit limit. The CFPB notes that the penalty APR can be applied to both existing balances and future transactions, and it often remains until you make several consecutive on‑time payments.
Typical penalty APRs range from 25% to 30% APR, but the exact number varies by issuer. Because the penalty rate can dramatically increase the cost of a carried balance, avoiding late payments is one of the fastest ways to protect your credit‑building progress.
How the three APRs interact on a single card
On a single card you may see a promotional APR for balance transfers, a separate promotional APR for purchases, and a purchase APR that takes over after each promo ends. If you trigger a penalty APR, it can override the promotional rates on all balances, not just the one that caused the default.
Reading the card’s terms sheet — especially the “APR” table — lets you map out the worst‑case scenario. Our credit‑cards/by‑score page filters cards by the typical APR ranges for fair‑credit applicants, helping you model the total cost.
Choosing a card when you’re rebuilding credit
When your FICO sits between 500 and 700, look for cards that offer a 0% introductory APR on balance transfers *and* a modest purchase APR (under 20%). Secured cards often have higher purchase APRs but no penalty APR if you keep the account in good standing.
Pair the card with a budgeting tool from our tools section to track utilization and payment dates, which reduces the risk of triggering a penalty APR while you build positive history.
