What makes this tool more useful
Estimate a fixed-rate loan payment and see how voluntary extra payments affect interest cost and payoff time. The result includes a transparent month-by-month model.
How the calculation works
Payments use the standard fixed-rate amortization formula. Extra payments reduce principal after scheduled interest is calculated each month.
Compare personal loans, auto loans or financing offers using the same amount and term assumptions.
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.
