How Credit Card Payments Work

Credit card payments are calculated based on several factors including your current balance, interest rate, and minimum payment requirements. The calculator uses the following formula to estimate your monthly payment:

Monthly Payment = (Current Balance × (APR/12)) / (1 - (1 + (APR/12))^-n)

Where:

Current Balance = Your outstanding credit card balance
APR = Annual Percentage Rate (expressed as a decimal)
n = Number of payments until balance is paid off

Minimum payments are typically a percentage of your current balance, often around 2-3%. The calculator can show you what that amount would be.

The Formula

The NAB Credit Card Payment Calculator uses the following formula to calculate your monthly payment:

Monthly Payment = (P × (r/12)) / (1 - (1 + (r/12))^-n)

Where:

P = Current credit card balance
r = Annual interest rate (APR) expressed as a decimal
n = Number of payments until balance is paid off

For minimum payments, the calculator uses:

Minimum Payment = Current Balance × (Minimum Payment Percentage / 100)

Worked Example

Let's say you have a credit card balance of $2,000 with an APR of 18%. If you want to pay off the balance in 12 months, the calculator would calculate:

Monthly Payment = ($2,000 × (0.18/12)) / (1 - (1 + (0.18/12))^-12) = $176.00

This means you would need to make monthly payments of $176.00 to pay off your $2,000 balance in 12 months with an 18% APR.

If you only make the minimum payment of 2%, that would be $40 per month, which would take much longer to pay off and cost you more in interest.
