What Is Purchase APR on a Credit Card?

Purchase APR is the annual percentage rate a credit card issuer uses to calculate interest on eligible purchases when you carry a balance. Understanding your purchase APR can help you estimate what borrowing on your credit card may cost and why paying your statement balance in full can make such a difference.

Quick answer: Purchase APR is the annual interest rate a credit card charges on eligible purchases when interest applies. If you carry a purchase balance beyond your grace period, interest may accumulate. Paying your statement balance in full by the due date generally helps you avoid purchase interest.

How Does Purchase APR Work?

When you make purchases with a credit card, those transactions are generally subject to the card’s purchase APR if interest applies. Credit card issuers typically calculate interest using a daily periodic rate based on the APR, which means interest can accumulate as you carry an eligible balance from one billing cycle to another.

When Does Purchase APR Apply?

Purchase APR generally becomes important when you carry an eligible purchase balance beyond the grace period. If your card offers a grace period and you pay the required statement balance in full by the due date, you can generally avoid interest on new purchases.

Is Purchase APR the Same as Credit Card APR?

Purchase APR is one type of credit card APR. A credit card may have different APRs for purchases, balance transfers and cash advances. Your card agreement shows which APR applies to each type of transaction.

What Is the Difference Between Purchase APR and Balance Transfer APR?

Purchase APR applies to eligible purchases you make with the card, while balance transfer APR applies to debt transferred from another account. These rates may be different, and a promotional balance transfer offer does not necessarily mean new purchases receive the same promotional rate.

What Is the Difference Between Purchase APR and Cash Advance APR?

Purchase APR applies to regular purchases, while cash advances can have a separate APR that may be higher. Cash advances may also begin accruing interest immediately and can include additional fees, making them different from ordinary credit card purchases.

How Is Purchase APR Used to Calculate Interest?

Credit card issuers generally convert your purchase APR into a daily periodic rate and apply it according to the card’s interest-calculation method. This is why the amount of interest you pay can depend on your APR, your balance and how long you carry that balance.

Does a Higher Purchase APR Mean You Always Pay More Interest?

Not necessarily. A higher purchase APR can result in more interest when you carry a balance, but the amount you actually pay also depends on your balance and payment behavior. If you qualify for a grace period and consistently pay your statement balance in full by the due date, you may avoid purchase interest altogether.

What Is a 0% Intro Purchase APR?

A 0% introductory purchase APR allows eligible purchases to avoid interest for a limited promotional period. When that period ends, any remaining eligible balance may begin accruing interest at the regular purchase APR according to the card’s terms.

What Happens When a 0% Purchase APR Offer Ends?

After the promotional period ends, the card’s regular purchase APR generally applies to any eligible balance that remains and to new purchases, subject to the card’s terms. Paying down the promotional balance before the introductory period expires can help you avoid carrying that balance at the regular rate.

Can Your Purchase APR Change?

It can. Some credit cards have a variable APR that can change when an underlying benchmark rate changes. Your APR may also change in other circumstances allowed by your card agreement and applicable rules, so review notices from your issuer and your account terms.

Where Can You Find Your Credit Card’s Purchase APR?

You can usually find your purchase APR on your credit card statement, in your cardholder agreement or through your online account. Look for a section that lists interest rates or interest charge calculations, especially if your card has different APRs for purchases, balance transfers and cash advances.

What Is a Good Purchase APR?

A good purchase APR is generally one that is competitive with other cards available to someone with a similar credit profile. Credit card rates can vary considerably, so compare the APR along with fees, rewards and other card features rather than looking at the interest rate alone.

How Can You Avoid Paying Purchase APR Interest?

If your credit card provides a grace period, paying your statement balance in full by the due date can generally prevent interest from being charged on new purchases. If you already carry a balance, review your card terms because you may need to pay the balance in full before a grace period on new purchases is restored.

Bottom Line

Purchase APR is the interest rate that generally applies when you carry an eligible purchase balance on your credit card. Knowing your purchase APR helps you understand the potential cost of carrying debt, but paying your statement balance in full by the due date can generally help you avoid purchase interest when a grace period applies.
