Loan Calculator
Work out a loan or mortgage monthly payment from the principal, interest rate, and term.
Use it to compare loan offers or estimate a mortgage payment before you apply.
The math runs locally using the standard amortization formula - no upload and no account.
Change the loan amount, rate, or term at any time - the monthly payment, total paid, and total interest recalculate immediately, with no submit button to click.
An optional 12-month amortization table breaks down how each monthly payment splits between principal and interest, even when the loan term itself runs longer than a year.
This is illustrative math only - it does not include taxes, insurance, or lender fees specific to your loan, and it does not replace advice from a licensed financial advisor.
