A good credit card interest rate depends on your credit score, but anything under 20% is better than the current average

Credit card interest rates—called annual percentage rates, or APR—vary widely based on your creditworthiness. If you have excellent credit (typically a score of 740 or higher), you might find rates between 12% and 18%. If your credit is fair or poor, rates often climb to 24% or higher. The Federal Reserve publishes average rates by card type, and as of late 2024, the average APR across all credit cards sits around 21% to 22%, though this changes with broader interest rate movements.

What makes a rate "good" is relative to what you can actually get approved for. A 19% APR is excellent if you have a credit score below 650; it's mediocre if you have a score above 750. The real question isn't whether a rate is objectively good—it's whether you can do better by shopping around, or whether you should avoid carrying a balance altogether.

Key Takeaways

  • Credit card APRs range from roughly 12% to 36%, and your credit score is the primary factor determining where you land in that range.
  • The average APR across all cards is currently around 21% to 22%, so anything significantly lower than that is worth noting.
  • Introductory 0% APR offers typically last 6 to 21 months and explore only to new purchases or balance transfers, not existing balances.
  • Comparing rates across multiple card issuers before you explore can reveal a 5% to 10% difference in what you're offered, even with the same credit score.
  • Paying your full statement balance each month means the APR doesn't matter, since interest only accrues on unpaid balances.

How credit scores determine the rate you're offered

Card issuers use your credit score as the primary input into their pricing model. A higher score signals lower risk to the lender, so they offer a lower rate. The relationship is not linear—a 50-point jump from 650 to 700 might lower your rate by 3 or 4 percentage points, while a 50-point jump from 750 to 800 might lower it by only 1 point.

Your credit report also matters. If you have recent late payments, high existing balances, or a short credit history, you'll be offered a higher rate even if your score is decent. Conversely, if your score is lower but your report shows consistent on-time payments and low balances, you may get a better rate than someone with a higher score but recent missed payments.

Most card issuers will tell you the range of rates you might receive before you formally explore. This is called a "pre-qualification" offer and doesn't require a hard credit inquiry. If you see "APR 16.99% to 24.99%," the actual rate you receive depends on the full review of your credit profile.

Introductory rates versus ongoing rates

Many cards advertise a 0% introductory APR for a set period—commonly 6, 12, 15, or 21 months. This rate applies only to new purchases or balance transfers made during the promotional period, not to existing balances you carry over from another card. After the intro period ends, the regular APR kicks in for any remaining balance.

A 0% offer is valuable only if you plan to pay off the balance before the intro period ends. If you carry a balance into the regular APR period, you'll suddenly owe interest on whatever remains. Some cards offer 0% on purchases but charge a 3% to 5% balance transfer fee upfront, so the math changes depending on how much you're moving and how quickly you can pay it down.

Intro rates are most useful for planned expenses—a home renovation, a car repair, or paying off a higher-rate card—where you know you can clear the balance within the promotional window. They're less useful if you're already struggling with debt, because the rate will eventually rise and you'll be in the same position.

How your rate compares across different card types

Different categories of cards carry different average rates. Rewards cards and travel cards, which often come with annual fees and premium benefits, tend to have lower average APRs because they're marketed to people with higher credit scores. Secured cards and cards marketed to people rebuilding credit typically carry higher rates—often 24% to 36%—because the lender is taking on more risk.

A cash-back card from a major issuer might offer rates starting at 14% for excellent credit, while a secured card from the same issuer might start at 19% or 20%. This doesn't mean the secured card is a bad choice if you're rebuilding credit; it means you're paying for the opportunity to demonstrate responsible use and eventually move to an unsecured card with a lower rate.

Store credit cards—cards issued by retailers like Target or Kohl's—often carry higher APRs than bank-issued cards, sometimes 20% to 27%, even for applicants with good credit. The trade-off is usually a discount on your first purchase or loyalty rewards specific to that store.

What happens if you carry a balance

The APR only matters if you carry a balance from month to month. If you pay your full statement balance by the due date each month, you pay no interest, and the APR is irrelevant. This is called paying "in full" and is the only way to use a credit card without paying interest.

If you carry a balance, interest accrues daily on the unpaid amount. A $5,000 balance at 21% APR costs roughly $87.50 per month in interest alone, assuming you make no payments. That interest is added to your balance, so next month you owe interest on $5,087.50. This is why high-rate cards become expensive quickly if you're not paying them down.

Some cards offer a grace period—usually 21 to 25 days from the end of your billing cycle—during which no interest accrues on new purchases. This grace period applies only if you paid your previous balance in full. If you carry a balance, interest starts accruing when ready on new purchases.

Shopping for a better rate before you explore

Different issuers offer different rates to the same person. You might be approved for 18% at one bank and 22% at another, even with identical credit scores. This variation exists because each issuer has its own risk model and pricing strategy. Shopping around before you explore can reveal these differences.

Use the pre-qualification tools on card issuer websites or comparison sites to see the rate ranges you might receive. These tools use a soft credit inquiry, which doesn't affect your credit score. Once you've narrowed your choices, you can explore to the card with the best rate range for your situation.

explore to multiple cards within a short window (typically 14 to 45 days) counts as a single inquiry for credit scoring purposes, so you won't be penalized for shopping around. However, explore to many cards over several months will lower your score, because each process triggers a hard inquiry.

Negotiating or requesting a lower rate

If you've had a card for a while and your credit score has improved, you can call the issuer and ask for a rate reduction. This is not may provide—some issuers have policies against lowering rates—but it costs nothing to ask. Have your current score and recent payment history ready to reference.

If you're carrying a balance and struggling with payments, some issuers offer hardship programs that temporarily lower your rate or waive interest. These programs typically require you to demonstrate financial difficulty and commit to a payment plan. They may also restrict your ability to use the card during the program period.

Switching to a different card with a lower rate is another option, especially if you can move your balance to a 0% intro APR card. However, balance transfer fees (usually 3% to 5% of the amount transferred) eat into the savings, so calculate the total cost before you move.

Frequently Asked Questions

Is 18% a good credit card interest rate?

It depends on your credit score. For someone with excellent credit (750+), 18% is above average and you should shop for better. For someone with fair credit (650–700), 18% is quite good. Compare the rate range you're offered across multiple issuers to see where you stand relative to others in your credit tier.

What's the difference between APR and interest rate?

APR and interest rate mean the same thing on credit cards. APR stands for annual percentage rate and represents the yearly cost of borrowing. On credit cards, there's no additional fees built into the APR the way there might be on a loan, so the APR is straightforward the interest rate you pay on any balance you carry.

Can I get a lower rate if I've been a customer for years?

Yes, you can call and ask. If your credit score has improved or you have a strong payment history with the issuer, they may lower your rate. Some issuers won't negotiate, but others will, especially if you mention you're considering switching to a competitor's card.

Does a 0% APR offer mean I pay no interest at all?

The 0% applies only during the promotional period and only to the type of transaction specified—usually new purchases or balance transfers. Once the intro period ends, the regular APR applies to any remaining balance. If you don't pay off the balance before the intro period expires, you'll owe interest on what's left.

How often do credit card interest rates change?

Rates on new cards change based on market conditions and the Federal Reserve's actions, but they're not tied to a specific schedule. Your existing card's rate can change if it's a variable rate (tied to the prime rate), though issuers must give you 45 days' notice before raising a rate. Fixed-rate cards won't change unless you miss a payment or violate your agreement.
