Free online loan & EMI calculator

This loan calculator estimates your monthly payment (EMI), the total interest you will pay, and the total cost of the loan over its full term. It works for mortgages, car loans, personal loans and any other fixed-rate, equal-instalment loan.

What it shows you

  • Monthly EMI — the fixed amount due each month.
  • Total interest — how much the loan costs you on top of the principal.
  • Total repayment — principal plus interest over the whole term.
  • A visual split of how much of your payments go to principal versus interest.

How to lower your interest

A shorter term or a lower interest rate both reduce the total interest you pay — try adjusting the term and rate to compare options. Because everything runs in your browser, your figures stay private and the tool works offline. Results are estimates and exclude fees, taxes and insurance.

Frequently Asked Questions

How is the monthly EMI calculated?

It uses the standard amortization formula: EMI = P × r × (1+r)ⁿ ÷ ((1+r)ⁿ − 1), where P is the principal, r is the monthly interest rate (annual rate ÷ 12 ÷ 100) and n is the number of monthly payments.

What does EMI stand for?

EMI means Equated Monthly Instalment — a fixed payment you make each month that covers both interest and part of the principal, so the loan is fully paid off by the end of the term.

Why do I pay so much interest early on?

In an amortized loan, early payments are mostly interest because interest is charged on the outstanding balance, which is highest at the start. As the balance falls, more of each payment goes to principal.

Does this work for home, car and personal loans?

Yes. The math is the same for any fixed-rate amortized loan — mortgages, auto loans and personal loans. Just enter the amount, annual rate and term in years.

Does it include fees, taxes or insurance?

No. This calculator shows principal and interest only. Real loans may add processing fees, insurance or taxes, so your actual payment can be slightly higher.

Is my financial information sent anywhere?

No. All calculations run in your browser. The numbers you enter are never uploaded or stored, keeping your financial details private.
