How Credit Card Interest Works

Credit card interest is calculated using the simple interest formula:

Interest Formula

Interest = (Principal × Rate × Time) / 100

Where:

Principal = Your current credit card balance
Rate = Annual percentage rate (APR)
Time = Number of days in the billing period

Most credit cards charge interest daily, so the formula is applied to each day's balance. The calculator uses this daily interest calculation to provide an accurate projection of your credit card situation.

Important Note

This calculator provides estimates only. Actual interest charges may vary based on your specific credit card terms and payment history. Always check your credit card statement for exact charges.

Example Calculation

Let's look at an example to see how the calculator works:

Current Balance	Interest Rate	Payment Frequency	Payment Amount
$2,000	18% APR	Monthly	$200

Using these inputs, the calculator would show:

Total interest paid: $324.56
Number of payments: 12
Total amount paid: $2,324.56

This example shows that paying $200 per month on a $2,000 balance at 18% APR would result in $324.56 in interest charges over 12 months.
