# How to Calculate Credit Card Interest?

Credit cards are a convenient way to make purchases and manage expenses, but it’s important to understand how credit card interest works. When you use a credit card, you’re essentially borrowing money from the credit card company. If you don’t pay off your balance in full each month, you’ll be charged interest on the remaining balance. The interest rate is typically expressed as an annual percentage rate (APR), and it can vary depending on the type of card and your creditworthiness. To calculate your credit card interest, you’ll need to know your APR, your outstanding balance, and the number of days in the billing cycle. With this information, you can determine how much interest you’ll be charged for the current billing period. Understanding how credit card interest is calculated can help you make informed decisions about your spending and debt repayment strategy.

## How to Calculate Credit Card Interest?

Calculating credit card interest in India involves understanding the interest rates charged by your credit card company, the balance on your card, and the duration for which the balance has been outstanding. Here’s a step-by-step guide on how to calculate credit card interest in India:

### 1. Know your credit card interest rate:

Your credit card company will charge you interest on your outstanding balance, which is typically expressed as an Annual Percentage Rate (APR) in India. The APR can range anywhere from 15% to 45%, depending on the credit card issuer, the type of card, and the cardholder’s creditworthiness.

### 2. Determine your average daily balance:

The next step is to determine your average daily balance (ADB), which is the average amount you owe on your credit card each day during the billing cycle. To calculate your ADB, add up the outstanding balance on your credit card for each day of the billing cycle and divide the total by the number of days in the billing cycle.

For example, if your credit card has an outstanding balance of Rs. 20,000 on the 1st day of the billing cycle, Rs. 15,000 on the 10th day, and Rs. 10,000 on the 20th day, your ADB for the billing cycle would be:

ADB = (Rs. 20,000 x 1) + (Rs. 15,000 x 10) + (Rs. 10,000 x 10) / 30 ADB = Rs. 15,000

### 3. Calculate the interest on your credit card:

Once you have determined your ADB, you can use it to calculate the interest on your credit card. To calculate the interest, multiply your ADB by your credit card’s daily interest rate and the number of days in the billing cycle.

For example, if your credit card has an APR of 18%, the daily interest rate would be:

Daily interest rate = (18/365)/100 Daily interest rate = 0.00049

If your billing cycle is 30 days, the interest on your credit card would be:

Interest = ADB x Daily interest rate x Number of days in billing cycle Interest = Rs. 15,000 x 0.00049 x 30 Interest = Rs. 221.85

Therefore, the interest charged on your credit card for this billing cycle would be Rs. 221.85.

### 4. Consider other fees and charges:

In addition to interest, credit card companies may charge other fees, such as late payment fees, over-limit fees, cash advance fees, etc. Make sure to factor in these fees when calculating the total amount due on your credit card.

## Bottom line:

To calculate credit card interest, you’ll need to know your APR, outstanding balance, and the number of days in the billing cycle. To determine how much interest, you’ll be charged for the current billing period, multiply your average daily balance by the daily periodic rate (DPR), which is your APR divided by 365. Then, multiply the result by the number of days in the billing cycle. This will give you the total interest charged for that billing period. Understanding how credit card interest is calculated can help you make informed decisions about your spending and debt repayment strategy. It’s important to make at least the minimum payment on your credit card balance each month to avoid late fees and negative impacts on your credit score.
