As with most good things, the intro-APR offer that comes with a new credit card must come to an end eventually. Once your promotional rate expires, your new purchase and/or balance transfer APR will revert back to the regular APR, also sometimes called the go-to rate or ongoing APR. The regular APR for any given credit card should be listed, along with all other important rate and fee data, in your cardholder agreement, as well as being included on your credit card statements. In most cases, the purchase APR and balance transfer APR will be the same, but some cards may charge different rates for each transaction type. Your regular credit card APR is determined based on a combination of the specific card’s set APR range and your individual creditworthiness. For example, a given credit card may have a potential APR range of 13% to 18%; someone with good credit may be offered a regular APR of 13%, while someone with average credit would likely be offered a rate closer to 18%. Although not widely known, you may be eligible to receive an interest rate reduction from your credit card issuer — if you ask for it. While issuers will rarely offer unsolicited APR decreases, studies have found that asking for a lower interest rate works more than half the time, and it can be especially effective if you’ve recently improved your credit scores.
