Frequently Asked Questions
Is my financial data stored or shared?
No. All calculations run locally in your browser. The values you enter are never sent to or stored on any server.
What loan types does this support?
Any fixed-rate loan — personal, auto, student, mortgage, or business. Enter your loan amount, annual rate, and term and the calculator handles the rest.
How does the extra payment calculation work?
The extra amount is added to each monthly payment. More principal is paid down each month, which reduces the remaining balance faster, cutting the total interest charged and shortening the loan term.
How accurate is this calculator?
It uses the standard fixed-rate amortization formula and is accurate for fixed-rate loans. It does not account for origination fees, variable rates, or specific lender rounding. Always verify with your lender before making financial decisions.
What is an amortization schedule?
An amortization schedule shows how each payment is split between repaying principal and paying interest. Early payments are mostly interest; over time, more of each payment reduces the principal as the balance falls.
