Formula Used
The calculator uses the following formula to estimate your credit card payments:
Monthly Payment Calculation
The monthly payment is calculated using the formula for an amortizing loan:
M = P [i(1 + i)^n] / [(1 + i)^n - 1]
Where:
- M = Monthly payment
- P = Principal loan amount (credit card balance)
- i = Monthly interest rate (APR/12/100)
- n = Number of payments (term in months)
This formula helps you understand how your monthly payments will be applied to both principal and interest over time.
Worked Example
Let's look at an example to see how the calculator works. Suppose you have a credit card balance of $5,000 with an APR of 18% and you plan to make monthly payments of $200.
The calculator will show you:
- Monthly Payment: $200
- Total Interest Paid: $1,200
- Total Payments: $6,200
- Term: 30 months
The repayment schedule chart will display how your balance decreases over time and how much of each payment goes toward interest.
