How to use Repayment Calculator

Provide the balance and monthly payment amount, and the calculator will estimate the number of periods needed to clear the debt.

What this calculator is for

This calculator is for situations where the central question is time, not payment size. It works well for quick debt planning and contract review when you want to know how long a stated payment is likely to keep you in repayment.

Tips

If the payment changes over time, run separate scenarios instead of assuming one fixed amount will describe the whole payoff path.
A payment only slightly above monthly interest can leave the balance outstanding for much longer than intuition suggests.
