How the calculation works

Each month applies interest, pays all minimums and sends the remaining budget to the priority debt. Freed minimum payments roll into later debts.

Important financial information

This calculator provides an educational estimate from the values you enter. It does not use live prices, predict returns or provide investment, tax or legal advice. Verify exchange rules, fees, rates and product terms before making a financial decision.

Private, fast and mobile-ready

The workspace runs with browser JavaScript and does not submit entered values to a Rantey calculation endpoint. Controls use readable labels, large touch targets and responsive result panels for narrow screens.
