How it works
Use the calculator first, then scan the details below when you want more context about the inputs, result, or assumptions.
How to use it
Enter the current balance, annual interest rate, monthly payment, and currency. Increase the payment to see how the payoff time changes.
Understand the result
Payoff time counts monthly payments. Total interest is the estimated cost above the original balance, assuming no new charges.
Example
A $10,000 balance at 18% with $300 monthly payments takes about 47 months to repay.
Notes
The estimate assumes a constant rate and fixed payment. It does not include fees, new spending, promotional rates, or lender rules.
