When opening a new credit card< or applying for a loan, your credit history matters in more ways than one. Your credit score plays a big part in determining whether you can get approved for credit, as well as the interest rates you pay. If you’ve never given much thought to the link between credit scores and interest rates before, here’s what you need to know.

How are credit scores and interest rates related?

The relationship between credit scores and interest rates is straightforward on the surface.

“In a nutshell, the higher your credit score, the lower the interest rate that you’ll qualify for and vice versa,” says Kari Lorz, personal finance expert and founder of Money for the Mamas.

Think of it this way. A lower interest rate is a lender’s way of rewarding you for good credit habits.

That doesn’t mean a higher rate is a punishment for having poor credit, however.

“It’s their own form of internal insurance on you as a customer,” says Lorz. Lenders can charge a higher rate to compensate for the possibility that, based on your past credit history, your odds of paying late or defaulting might be higher.

Why credit scores matter

It may not seem like a three-digit number can have that much of an impact on your financial life, but credit scores carry a lot of weight.

“Although there are other factors that can impact your interest rate, your credit score is one of the key measures lenders rely on to determine if you’re a reliable borrower,” says Richard Best, personal finance expert at

While there are different credit scoring models, including FICO and VantageScores, they tend to focus on the same considerations:

  • Payment history
  • Credit usage
  • Credit mix
  • Credit age
  • Inquiries for credit

Credit scores are the easiest way for lenders to tell at a glance how likely you are to pay back what you owe and on time.

How credit scores affect credit card APRs

Your credit card’s annual percentage rate or APR represents the annualized cost of carrying a balance when your interest rate and card fees are factored in. Credit scores help determine the interest rates and fees credit card companies charge you, says Howard Dvorkin, certified public accountant and personal finance expert at

“A lower credit score may tell lenders a person is not likely to pay back a loan, and this increases a consumer’s APR,” says Dvorkin.

Higher APRs make carrying a balance more expensive over time.

For example, say you charge $5,000 to your travel rewards card to book a vacation. You plan to pay $250 a month toward the balance. Assuming a 17.25% APR, it would take you 24 months to pay it off and cost you $938 in interest charges.

Now, say that a low credit score results in an APR of 22.25% instead. It’ll now take you 26 months to pay off the balance but your total interest paid jumps to $1,306. The difference in your card’s APR costs you nearly $400 more.

You can run your own numbers using’s credit card payoff calculator.

Note that, while credit scores matter for determining APR, there are some things you can’t control.

“A factor you can’t influence is the national prime rate,” says Lorz. This is the interest rate at which banks lend to their most creditworthy customers.

“If it goes up, so does your APR,” she says.

Average credit card interest rate by credit score

Credit scores can be broken up into ranges, with each one assigned a different credit score rating. For example, here’s how FICO score ranges break down, according to Experian:

Credit score rangeCredit score
800 to 850Exceptional
740 to 799Very good
670 to 739Good
580 to 669Fair
300 to 579Very poor

Understanding those ranges can help you get a better sense of what you might pay in interest, based on which category you’re in.

While credit card companies usually don’t disclose the minimum credit scores they require to qualify, many do specify whether a card is designed for fair, good or excellent credit.

For example, the Discover it® Cash Back is designed for people with a score in the good to excellent range. Its APR ranges from 11.99% to 22.99% variable, based on creditworthiness.

The Capital One QuicksilverOne Cash Rewards Credit Card, on the other hand, is designed for people with fair or average credit. That’s reflected in the card’s regular variable APR of 26.99%.

How credit scores affect other interest rates

While you might be primarily concerned with what your credit score means for your credit card’s APR, there are other times it matters.

If you’re planning to buy a car, for example, a good credit score could make a substantial difference in interest paid and money saved.

“Credit scores between 550 and 679 are considered subprime,” says Best. So, if you were looking for a car loan, for example, that might equate to an APR ranging anywhere from 13% to 18%.

On the other hand, a score of 720 or better could qualify you for the lowest rates. Best says a score of 770 or higher could put you in line for a 0% financing deal.

Credit scores can also affect the cost of buying a home. While mortgage rates tend to be significantly lower than credit card rates or car loan rates, every little bit you can shave off your rate counts when you’re borrowing a substantially higher amount of money.

For example, say you’re taking on a $300,000 mortgage. According to myFICO, a 620 credit score could result in an average rate of 4.711% with a $1,558 monthly payment. A 760 credit score could help you lock in a rate of 3.122% instead, with a monthly payment of $1,285.

That’s significantly less money you’d have to pay each month toward a home and it could save you tens of thousands of dollars over the life of the loan.

Tips for getting a good APR

Getting a good APR on a credit card or another type of loan comes down to making yourself as attractive to lenders as possible.

“It’s hard to 100% ensure that you’ll get a good APR on your credit score alone,” says Lorz. “However, you do have a good bit of control on your rate just with your score.”

The best way to leverage that control is to work on improving your credit score, says Dvorkin. “This can be achieved by paying your bills on time, every time, and not maxing out your credit cards but conversely, paying them off in full every month.”

While loans do have an impact on your credit score, credit cards tend to carry more weight with regard to credit utilization. If you’re working on improving your credit score to have a shot at better APRs, make sure you’re choosing the right cards to do it.

Review your card’s terms, conditions, fees, APR and benefits at least once per year so you know what you’re paying for and what you’re getting in return. Resist the urge to close older accounts unless they offer absolutely no value since that could hurt your credit score in the short run. (Closing a credit card account can decrease your overall available credit, which could inflate your credit utilization ratio.)

And consider opening a new credit card account with more favorable terms or features, but be strategic about it. Each new inquiry for credit can trim a few points off your score, so take the time to research which cards are the best fit, based on rewards, card perks, APR and fees.

What is a good APR for a credit card?

A good credit card APR might not matter much to you if you always pay your bill in full every month, have a big emergency fund and know you’ll never use the card to finance a large purchase. But you should pay close attention to the APR if you ever carry a balance.
