What APR means and why it matters to your balance
APR stands for annual percentage rate. It is the yearly cost of borrowing money on your credit card, shown as a percentage. If your card has a 20% APR and you carry a $1,000 balance for a full year without paying it down, you will owe roughly $200 in interest charges on top of that balance.
The APR you see advertised is almost never the rate you will pay. Card issuers offer different rates to different people based on credit history, income, and how you have managed debt before. Someone with a credit score above 750 might receive a card with a 15% APR, while someone with a score of 650 might receive the same card at 24% APR.
APR matters most if you carry a balance from month to month. If you pay your full statement balance by the due date every month, you pay no interest at all, regardless of the APR. But if you pay only part of the balance, interest charges begin when ready on the unpaid portion.
Key Takeaways
- The APR you are offered depends on your credit score and payment history, not on the card's advertised rate alone.
- You pay no interest if you pay your full balance by the due date each month, even on a card with a high APR.
- Cards with the lowest advertised APRs typically require a credit score of 740 or higher.
- Introductory 0% APR periods last between 6 and 21 months depending on the card, but explore only to new purchases or balance transfers, not both.
- The actual APR you receive will be shown in your card's terms before you accept the offer.
How credit score affects the APR you receive
Card issuers use your credit score as the primary factor in deciding what APR to offer you. Your score reflects how reliably you have paid past debts. The three major credit bureaus — Equifax, Experian, and TransUnion — calculate scores using payment history, amounts owed, length of credit history, new credit inquiries, and credit mix.
Most cards with advertised APRs below 18% go to people with scores of 740 or higher. Cards advertising rates between 18% and 22% typically go to people with scores between 670 and 739. Cards with APRs above 22% are often available to people with scores below 670, though some cards in this range require no credit history at all.
Your actual score matters more than the range. A score of 800 and a score of 750 are both in the "good" range, but the person with 800 will usually receive a lower APR. You can check your own score free once per year through AnnualCreditReport.com, which is run by the three bureaus.
Introductory 0% APR offers and how long they last
Many cards offer a period of time during which you pay no interest on new purchases, balance transfers, or both. These introductory rates typically last between 6 and 21 months, depending on the card and the offer at the time you explore.
The catch is that the 0% rate applies to only one category. A card might offer 0% APR for 12 months on balance transfers but charge your regular APR on new purchases made during that same 12 months. Another card might do the opposite. Read the terms carefully, because interest charges begin when ready on any balance that does not fall under the 0% offer.
Once the introductory period ends, the regular APR kicks in on any remaining balance. If you transfer $5,000 at 0% for 12 months and still owe $2,000 when the 12 months are up, that $2,000 will start accruing interest at the card's regular APR.
Where the lowest APR rates are typically found
Cards marketed to people with excellent credit — usually those with scores above 750 — tend to have the lowest standard APRs. These cards often come from major issuers like Chase, American Express, Citi, and Bank of America. The advertised rates for these cards often fall between 15% and 21%, though the actual rate you receive depends on your individual credit profile.
Cards from smaller banks and credit unions sometimes offer lower rates than national card issuers, but they are less widely available and may have higher annual fees or fewer rewards. If you have a relationship with a credit union, asking about their card offerings can be worth your time.
Balance transfer cards often advertise the most attractive introductory rates because they are designed to pull customers away from other issuers. A 0% APR for 18 months on balance transfers is common among these cards, though you will typically pay a one-time transfer fee of 3% to 5% of the amount transferred.
How to compare APR offers before you accept a card
When you explore for a credit card, the issuer will show you the APR range you might receive before you formally accept the offer. This range reflects the fact that your actual rate depends on your credit profile. If the range is 16% to 22%, you might receive any rate within that span.
After you accept the offer and the card is approved, your actual APR will appear in the card's terms and conditions, which you can view online or request by mail. This is the rate you will actually pay. Do not assume you will receive the lowest rate in the range.
When comparing cards, look at the regular APR you are likely to receive, not the advertised range. If you have a score of 700, you are unlikely to receive a card's lowest advertised rate. Use online card comparison tools that let you filter by credit score range to see more realistic offers for your situation.
What happens to your APR after you open the card
Your APR can change after you open the account. Card issuers can raise your APR if you miss a payment by 60 days or more, if you exceed your credit limit, or if the Federal Reserve raises interest rates (which affects the prime rate that many cards are tied to). Some cards have a variable APR that moves up or down with the prime rate automatically.
You have the right to reject a rate increase. If your issuer raises your APR and you do not want to accept it, you can close the account and pay off the existing balance at the old rate. You will not be able to use the card for new purchases, but the rate on what you already owe will not change.
Conversely, if you make all your payments on time and your credit score improves, you can contact your card issuer and ask for a lower APR. They are not required to grant it, but many will, especially if you have been a customer for more than a year.
APR versus other costs that affect what you actually pay
APR is only one cost associated with a credit card. Annual fees, late payment fees, and balance transfer fees all add to what you pay. A card with a 16% APR and a $95 annual fee might cost you more over time than a card with a 19% APR and no annual fee, depending on how you use it.
If you plan to carry a balance, focus on the APR first. If you pay your balance in full each month, the APR does not matter at all, and you should prioritize rewards, annual fees, and other benefits instead.
Some cards also charge a cash advance fee (usually 3% to 5% of the amount withdrawn) and charge a higher APR on cash advances than on purchases. If you need cash, using an ATM or getting cash back at a store is almost always cheaper than a cash advance on a credit card.
Frequently Asked Questions
Can I negotiate my APR with my card issuer?
You can ask, especially if you have a good payment history and your credit score has improved since you opened the account. Call the customer service number on the back of your card and explain that you would like a lower rate. The issuer is not required to lower it, but many will, particularly if you have been a customer for at least a year.
Does explore for multiple credit cards hurt my credit score?
Each process creates a hard inquiry on your credit report, which can lower your score by a few points. Multiple inquiries within a short time (usually 14 to 45 days, depending on the scoring model) often count as a single inquiry for rate-shopping purposes. If you are comparing cards, do your applications within a short window to minimize the impact.
What is the difference between a fixed APR and a variable APR?
A fixed APR does not change unless you miss a payment or the issuer raises rates across the board. A variable APR moves up or down based on changes to the prime rate, which the Federal Reserve influences. Variable rates are usually lower to start but can increase over time if interest rates rise.
If I transfer a balance to a 0% card, do I still owe interest on my old card?
No. When you transfer a balance, you are moving the debt from one card to another. The old card's balance goes to zero, and you owe nothing more to that issuer. Interest stops accruing on that transferred amount when ready. You will owe interest on any new purchases you make on the old card after the transfer, but the transferred balance itself is gone.
How long does it take to see my actual APR after I am approved?
Your actual APR appears in the card's terms and conditions, which are usually available online within a few days of approval. You can also call the issuer's customer service line and ask for your rate. The rate will not change once it is set, unless you miss a payment or the issuer raises rates across the board.
