About This Debt Payoff Calculator

This free debt payoff calculator estimates how many months it will take to clear a debt and how much total interest you will pay, based on a fixed monthly repayment. If your repayment is lower than the monthly interest, the balance never reduces and the calculator will tell you so.

This is general information only and not financial advice. If you are struggling with debt, free and confidential help is available from the National Debt Helpline on 1800 007 007.

Frequently Asked Questions

How can I pay off debt faster?+
Pay more than the minimum, and target either the highest interest rate first (the avalanche method) or the smallest balance first (the snowball method) to build momentum.
What if my repayment barely covers the interest?+
If your repayment is less than the monthly interest charge, the balance will not go down. Increasing the repayment or seeking help is important — call the National Debt Helpline on 1800 007 007 (free).
Does this include fees?+
No. This calculator only models interest, not account or late fees. Real debts may cost more. This is general information, not financial advice.
