Loan & Mortgage Calculator

Usage Guide

Enter the loan amount, annual interest rate, and term, then pick a repayment method to get the monthly payment, total interest, and total repayment, plus an amortization schedule (first 12 months and the final one). Equal payment (annuity) keeps the monthly amount fixed with interest front-loaded; equal principal repays a fixed principal each month, so payments shrink over time and total interest is lower, but early payments are higher. Switch methods to compare the interest gap directly.

Examples

• Compare equal payment and equal principal on a 1,000,000 loan over 30 years.
• Try 20 versus 30 years to see how term length trades monthly load for total interest.
• Read the remaining balance at month 12 to judge an early repayment.

FAQ

• Does it match my bank? Calculations follow standard formulas; actual bills may differ around disbursement dates, first periods, or rate resets.
• Why does equal principal change every month? Principal is fixed while interest follows the remaining balance, so each payment decreases.
• Can it model prepayment? Simulate by shortening the term or reducing the amount; final rules follow your loan contract.
