How high can a credit card’s interest rate go?

Is there any limit to how high your credit card interest rates can go? You may be surprised to learn that, generally, there isn’t. As many cardholders have seen, average card interest rates have remained stagnant above 20 percent for months.

The steadily-high rates have been influenced by the Federal Reserve’s ongoing fight against inflation. Beyond the Fed’s impact, there are other situations in which your card issuer can raise interest rates on your account without notice.

When can your card’s interest rate go up?

For one, if you have an introductory 0 percent APR, your issuer will raise your rate automatically once the promotional period ends.

If you don’t make at least your minimum payment for 60 days, your issuer could impose a penalty interest rate on your account.

Otherwise, a card issuer generally cannot hike your interest rate during the first year you open the account. After that period, other than in the situations outlined above, it must notify you 45 days in advance about any rate changes, per the Credit Card Accountability Responsibility and Disclosure Act — or CARD Act.

Any new purchases you charge more than two weeks after this notice period will be assessed interest at the new rate. If you disagree with the interest rate change, you can cancel your credit card instead. In that case, you’d pay off any existing balances on the account at your lower current rate.

There is no limit on card interest rates

As for how high your card interest rate can go, the CARD Act did not establish a ceiling. Usury refers to lending at a rate of interest that is so high as to be unreasonable. While many states have usury laws that limit the interest rates that lenders can charge, many of these state laws don’t apply to credit card rates. Instead, they apply mainly to loans, and even then, financial institutions tend to get around them through exemptions.

Maximum credit card interest rates by state

Because so many exemptions to usury laws exist, states effectively don’t have credit card interest rate caps. In California, for example, the state’s usury law limits rates on consumer loans to 10 percent. However, California also exempts loans made by banks and credit unions from this usury law. Many other states also exempt banks from their usury laws.

Banks can also charge interest rates based on the prevailing rates in the state where they are headquartered, rather than in the consumer’s state. To elaborate, consumers are beholden to the rules of the credit card agreement, which often stipulate that rates are determined by the bank’s jurisdiction and not the consumer’s. That’s why credit card issuers tend to be based in states such as Delaware, Missouri and South Dakota that have less stringent (or nonexistent) usury laws.

In some circumstances, banks can charge the rates permitted in a state where they have branches and not where they have their headquarters, even if the borrower lives in another state. This means that the only financial institutions typically affected by usury laws tend to be lending companies that are not part of a bank, such as payday lenders.

Practically speaking, there is no limit on how high your card interest rate can go.

Highest credit card interest rates

Even though usury laws don’t affect credit card companies, they still tend to offer APRs with a range similar to competitors, dependent on various factors. This is because these card issuers still want to remain competitive and don’t want to risk pushing their products too far out of the range of what consumers can get from competing lenders. Here’s a list of popular issuers and the APRs they’re offering on various card products at the time of writing:

Examples of high credit card interest rates

• American Express: 29.99 percent maximum variable APR on multiple cards, including the Blue Cash Preferred® Card from American Express and the Blue Cash Everyday® Card from American Express (18.49%-29.49% Variable APR)
• Capital One: 29.99 percent maximum variable APR on multiple cards, including the Capital One Platinum Credit Card and the Capital One QuicksilverOne Cash Rewards Credit Card
• Discover: 28.24 percent maximum variable APR on multiple cards, including the Discover it® Cash Back and the Discover it® Miles  (18.74% - 27.74% Variable APR)
• Chase: 29.49 percent maximum variable APR on the Chase Sapphire Reserve® card (21.99% - 28.99% Variable APR)

Note that these interest rates are the listed maximums for a card’s APR range, which can vary based on the applicant’s creditworthiness and the Federal Reserve’s prime rate. This means applicants could still get a lower rate on many cards. Other cards outside of this list may also have higher APRs if they’re marketed toward applicants with lower credit scores.

No matter what credit card you own, it’s essential to know your card’s APR, especially since your state’s usury laws likely won’t matter to your card issuer.

Rate caps still apply in some cases

However, there are some situations in which consumers get the protection of a cap on their interest rates. One exception is for cards issued by a credit union. The law states that federal credit unions can’t charge their members a rate higher than 18 percent, including all finance charges, on their unpaid balances.

Also, if you are actively serving in the military or are a covered dependent of such a person, the Military Lending Act caps the interest rates, including finance charges, on your credit card debt at 36 percent.

For any loans taken out or credit card debt incurred before you became an active servicemember, the Servicemembers Civil Relief Act provides relief, with interest rates on cards for military members capped at 6 percent. This is to ensure service members can focus their attention on serving the nation. For loans, you’ll need to notify your lender about your military service and ask for the cap.

Attempts to cap rates

There have been some attempts to set national interest rate caps on credit card debt. For instance, the Veterans and Consumers Fair Credit Act would cap interest rates for consumers at 36 percent by extending the Military Lending Act’s interest rate cap to civilians, too.

In 2019, Sen. Bernie Sanders and Rep. Alexandria Ocasio-Cortez also attempted to set a 15 percent cap on credit card interest rates, though their efforts didn’t take off.

“We will send a clear message to the modern-day loan sharks that we will not allow them to make billions off of keeping working Americans in a state of perpetual debt,” Sanders said at the time, in an online statement. “We must stop the exploitative lending practices suppressing economically distressed communities. We must ensure every American has the opportunity to grow financially.”

Their proposed federal law would also have allowed states to create even lower interest rate caps.

The bottom line

The CARD Act does not include a cap on credit card interest rates. While state-level interest rate caps and usury laws exist, many of those laws don’t apply to credit card rates in practice. Moreover, banks can charge interest rates that apply to the states where they are based, rather than the state where you live.

Read the fine print of your card’s agreement to determine which state’s laws apply to your credit card balance, and watch out for communications from your issuer. Your card issuer will generally have to give you 45 days’ advance notice if it wants to increase your rate.
