# How Does Credit Card Interest Work?

You may be wondering how to calculate your credit card interest. To begin, you should know that interest is calculated daily. Credit card companies multiply the balance on your account by the daily interest rate. This daily rate is equal to the annual interest rate divided by 365 days. Each day, you will be charged the same amount as the previous day’s balance, but the rate will be higher because it is compounded daily. Typically, credit card interest is higher than other forms of debt, so it is important to understand how this works.

## Calculating credit card interest

Calculating credit card interest is a basic tool that will help you understand the cost of your balance and how much money you will be paying over time. A credit card statement should show the interest rate you owe on the balance and the average annual percentage rate. This information is very important as credit card interest can add up quickly. In addition, if you have a balance that fluctuates each month, it will be easy to see what you are paying every month.

## Compounding interest

Most credit card issuers use a type of interest known as compounding. This type of interest charges on the unpaid balance at the end of each month. The daily rate of interest varies based on the terms of your account. In our example, we are spending \$5,000 on a credit card with a 25% APR on purchases over a 31-day billing cycle. Because the interest is compounding daily, this rate could add up to nearly 18% by the end of the month.

## Grace period

Having a grace period on your credit card can save you from paying interest on new purchases if you pay your balance in full before the due date. However, if you do not pay your balance in full by the due date, you will begin accruing interest on your purchases immediately. To avoid paying interest during a grace period, you must pay your balance in full every month, before the due date. Unless you have a zero percent balance transfer offer, you will be charged interest on your purchase from the moment you make the transaction.

## Variable APRs

Credit card interest rates vary from day to day. These vary due to the Prime Rate, which is the interest rate banks charge the highest credit-worthy customers. It is a widely-followed benchmark, which can fluctuate. Large financial institutions also use the LIBOR rate, a British version of the Prime Rate. The prime rate is determined by a complex set of rules that determine how much interest a bank will charge you on a loan.

## Calculating daily rate

In order to determine how much interest you are paying on a credit card, you will need to know the APR or annual percentage rate. You can calculate the APR by multiplying it by 365 days. In some cases, banks will divide the APR by 360 instead of 365, but this is usually a minor difference. In any case, the daily credit card interest rate will be higher than the monthly interest rate, and the difference will be more than you realize.
