Types of Credit Card APR
One credit card usually carries several different APRs, each applying to a different kind of transaction. Knowing which is which tells you what any given balance is really costing you.
Short version: a typical card has up to five APRs, purchase, cash advance, balance transfer, penalty, and sometimes a promotional intro rate, and only the purchase APR usually comes with a grace period. Cash advances and most balance transfers start accruing interest immediately. The table below breaks down all five.
The five APRs on a typical card
| APR type | Applies to | Grace period? |
|---|---|---|
| Purchase | Everyday purchases you make | Yes, if you pay in full |
| Cash advance | Cash withdrawn against your credit line | No |
| Balance transfer | Debt moved from another card | No (often 0% intro) |
| Penalty | Kicks in after you break the terms | N/A |
| Introductory | A promo rate for a set period | Varies |

Purchase APR
The rate on things you buy, and the one most people mean by "my APR." You only pay it if you carry a balance past the due date. Pay your statement in full and the grace period keeps purchase interest at zero. See what a balance costs at your purchase APR.
Cash advance APR
Usually several points higher than your purchase APR, and it comes with no grace period plus an upfront fee, so interest starts the day you take the cash. This makes cash advances one of the most expensive ways to use a card. Calculate a cash advance's full cost.
Balance transfer APR
The rate on a balance moved from another card. The best transfer cards offer a 0% introductory rate for a set number of months, with a transfer fee of about 3% to 5%. When the intro period ends, the regular rate applies to whatever is left. See if a balance transfer saves you money.
Penalty APR
A higher rate an issuer can apply after you break the card's terms, most often by paying late. It can run up to around 29.99%. Federal law requires 45 days' notice before it takes effect, and once triggered it can stay in place for at least six months. Paying on time is the way to avoid it entirely. More on penalty APR.
Introductory / 0% APR
A promotional rate, often 0%, for a set period after you open the card. It can apply to purchases, balance transfers, or both. When it ends, the regular APR applies to any remaining balance. On a true 0% intro card you aren't charged retroactive interest. That only happens with deferred interest promotions, common on store cards, where missing the payoff deadline can make you owe all the accrued interest at once. More on 0% intro APR and deferred interest.
Fixed vs variable APR
Most credit cards carry a variable APR tied to an index, usually the prime rate. When the Federal Reserve moves rates, your APR can move with it. A fixed APR doesn't track an index, but despite the name the issuer can still change it, and must give you advance notice when they do. Either type can rise to a penalty APR if you miss payments.
Where to find your card's APRs
All of them are listed in the rates and fees table, often called the Schumer box, in your cardholder agreement, and they appear on your monthly statement. If you aren't sure which rate applies to a balance, that table is the place to check. For the mechanics of how any of these rates turns into a dollar figure, see the guide on how credit card interest is calculated.
