Formula Explanation

Automatic Minimum Payment

The minimum payment is calculated as the monthly interest charge plus 1% of the balance:

min_payment = (balance * monthly_rate) + (balance * 0.01)

Fixed Payment

When using a fixed payment amount, the same payment is applied each month until the balance is paid off. The payment must be greater than the monthly interest charge to make progress.

Compounding Information:

Interest is compounded monthly. Each month, the interest charge is calculated on your current balance, then added to the balance before your payment is applied.

Each month, interest is charged on the remaining balance, and the balance decreases by your payment minus interest charges. Larger payments pay off the balance faster and cost less in total interest.
