Frequently Asked Questions
How is the monthly loan payment calculated? ↓
Monthly payments use the standard standard fixed-rate amortization formula: M = P * [r(1+r)^n] / [(1+r)^n - 1], where P is principal, r is the monthly interest rate, and n is the total number of monthly payments.
Are my financial details stored or tracked? ↓
No. All calculations are executed completely inside your browser. No loan amounts, income figures, or terms are ever recorded, saved, or sent over the network.
How does extra monthly payment affect my loan? ↓
Any extra payment made above your required monthly amount goes directly toward reducing the principal balance. This accelerates the payoff schedule and can save thousands of dollars in total interest.
Can I export the amortization schedule? ↓
Yes. You can view the yearly and monthly schedule tables and export the complete schedule as a CSV spreadsheet for Excel or Google Sheets.
