Frequently asked questions
Everything you need to know about paying off loans early and getting the most from the calculator.
Is the early payoff calculator free to use?
Yes, completely free. There is no signup, no paywall, and no limit on how many scenarios you can run.
Does making extra payments actually save money?
Yes. Interest is charged on your remaining balance, so paying extra toward principal removes all the future interest that amount would have accrued. Even small extra payments compound into large savings over the life of a loan.
Will extra payments go toward my principal automatically?
Not always. Some lenders apply extra funds to future interest or the next payment instead of principal. Tell your servicer, in writing if needed, to apply extra payments to the principal balance.
Should I make a biweekly payment or one large extra payment?
A biweekly-accelerated schedule results in roughly one extra monthly payment per year and is easy to automate. A single lump sum early in the loan has an outsized effect because it reduces interest for the longest time. The calculator lets you compare both.
Are there penalties for paying off a loan early?
Most modern mortgages and auto loans have no prepayment penalty, but some do. Check your loan agreement for a prepayment penalty clause before making large extra payments.
Does this calculator work for mortgages, car loans, and student loans?
Yes. Any fixed-rate, fully amortizing loan uses the same math, so the tool works for mortgages, auto loans, personal loans, and most student loans.
Do you store my financial information?
No personal or identifying information is required or stored. Calculations run on the server for the result only; we keep no data that could identify you.
How accurate are the results?
The calculator runs a full month-by-month amortization schedule, so it is accurate for fixed-rate loans. Real statements may differ by a few dollars due to rounding, escrow, fees, or variable rates. Always confirm with your lender.
