Understanding How Interest Rates Work on Credit Cards

​

If you've ever carried a balance on your credit card or cards, you've likely seen how fast that debt can grow. That's the power of credit card interest rates - often misunderstood but critically important to your financial health. Here's a simple breakdown to help you understand how credit card interest works and what you can do to minimize its impact.

​

​

What is a Credit Card Interest Rate?

​

A credit card interest rate is the cost of borrowing money from your credit card issuer. It's expressed as an APR, or Annual Percentage Rate. This is the yearly rate you'll pay if you carry a balance month to month.

​

For example, if your credit card has a 24% APR and you carry a balance of $1,000 for a year without paying it off, you could end up paying $240 in interest alone - and that's before any fees or additional charges.

​​

​

When is Interest Charged?

​

Most credit cards give you a grace period - typically 21 to 25 days after your billing cycle ends. If you pay your full balance on time every month, you won't pay interest on purchases.

​

However, if you only make the minimum payment or carry any part of your balance into the next month, your card will charge interest on the unpaid amount - and possibly on new purchases too, depending on your card's terms.

​

​​

How is Credit Card Interest Calculated?

​

Credit card interest is usually calculated daily, using something called the Daily Periodic Rate (DPR). Here's a simple breakdown:

​

1.) APR / 365 = Daily Periodic Rate

​

• Example: 24% APR / 365 = 0.0658% Daily Rate

​

2.) Your daily balance x DPR x days in billing cycle = Interest Charged

​

• Example: $1,000 x 0.0658% x 30 days = $19.74 in interest for the month

​

That means the longer you carry a balance, the more interest piles up each day.

​

Why are Credit Card Interest Rates so High?

​

Credit card interest rates are much higher than other loans like mortgages or car loans. Why?

​

• Unsecured Debt - There's no collateral (like a house or car), so lenders take more risk

• Revolving Credit - You can borrow repeatedly, making it hard to predict how much you'll owe

• Credit Risk - Lenders set rates based on your credit score. The lower your score, the higher your rate may be

Tips to Minimize or Avoid Paying Interest

​

• Pay your balance in full every month

• Make payments early or often during the month to reduce your average daily balance

• Look for 0% APR introductory offers - but read the fine print

• Consider a balance transfer card to reduce or consolidate high interest debt

• Use a payoff strategy, like the debt snowball or debt avalanche, to take control

• Consider a debt resolution plan to lower your payments and focus on saving money

​

​

Bottom Line

​

Understanding how credit card interest works is key to managing your debt and protecting your financial future. Interest can feel invisible until it snowballs - so staying proactive with payments, knowing your APR, and avoiding high balances can make a big difference.
