Frequently Asked Questions

How is the monthly payment calculated?▾

The tool uses the standard amortization formula: M = P × [r(1+r)^n] / [(1+r)^n − 1], where P is the principal, r is the monthly interest rate, and n is the total number of payments.

Does this calculator handle variable-rate loans?▾

No. This calculator is designed for fixed-rate loans. Variable-rate loan payments change over time and require a different calculation method.

Can I see a full amortization schedule?▾

Yes. The tool generates a complete month-by-month amortization table showing how each payment is split between principal and interest.

Is my financial data sent to a server?▾

No. All calculations happen entirely in your browser. Your loan information is never transmitted to any server.
