Frequently Asked Questions
How is the monthly loan payment calculated?
The calculator uses standard fixed-rate amortization: M = P × [ r(1 + r)ⁿ ] / [ (1 + r)ⁿ - 1 ], where P is principal, r is monthly interest rate, and n is the total number of payments.
Does this calculator support mortgages, auto loans, and personal loans?
Yes! Any fixed-rate installment loan (including home mortgages, auto financing, and personal loans) follows this identical compounding schedule.
Can I view year-by-year payoff milestones?
Yes! Toggle between the Yearly View and First 24 Months view to inspect how early payments are weighted toward interest versus late payments toward principal.
Are my financial figures uploaded or tracked?
No! 100% of calculations run strictly inside your web browser. Zero financial data is ever collected or uploaded.
