How Credit Card Payments Are Calculated

Credit card payments are calculated using the formula for the monthly payment of a loan with compound interest. The formula is:

Monthly Payment = P × (r(1 + r)^n) / ((1 + r)^n - 1)

Where:

P = Purchase Amount
r = Monthly Interest Rate (APR ÷ 12 ÷ 100)
n = Number of Payments (Repayment Period in Months)

This formula calculates the fixed monthly payment required to pay off the credit card balance over the selected repayment period. The total interest paid is the total repayment amount minus the original purchase amount.

Note: This calculator assumes a fixed monthly payment and does not account for variable interest rates or additional fees that may apply to your specific credit card.

Example Calculation

Let's look at an example to understand how the calculator works. Suppose you make a purchase of $1,000 with a Standard Bank credit card that has an interest rate of 18% APR and you plan to repay it over 12 months.

Using the formula:

Monthly Payment = $1,000 × (0.015(1 + 0.015)^12) / ((1 + 0.015)^12 - 1)

Monthly Payment ≈ $87.91

Over 12 months, you would pay a total of $1,055.00, with $55.00 going to interest.

This example shows how interest can add up over time, making it important to pay off your credit card balance as quickly as possible.
