About this calculator
The Loan Calculator gives you a quick way to work out a loan's repayment and total cost. Enter your amount to borrow, annual interest rate and repayment period; it then returns the monthly payment, total interest and a schedule, worked out with the reducing-balance EMI formula the moment you calculate. It runs fully in the browser, so it is private by design and works offline once loaded.
It reports the monthly payment, the total of all payments, and the total interest, so you can compare offers and terms at a glance.
How to use
- Enter the amount you want to borrow.
- Enter the annual interest rate for the loan.

Technical notes
Loan Calculator uses the standard reducing-balance EMI formula E = P·r·(1+r)^n / ((1+r)^n − 1), where r is the monthly rate and n the number of months.
Actual repayments can differ once the lender adds fees, insurance or rate changes.
Because it runs locally, results appear instantly with no server round-trip.
FAQ
What loans does this work for?
Any fixed-rate, equal-instalment loan — personal, auto, home, or business. Enter the amount, rate, and term to see the monthly payment.
What is the difference between EMI and total payment?
The EMI is your fixed monthly amount; the total payment is the EMI multiplied by the number of months, which includes all the interest over the term.
Does a lower rate always mean a lower total cost?
For the same term, yes — a lower rate reduces both the monthly payment and the total interest paid.
Does the Loan Calculator send my data to a server?
No. The Loan Calculator runs entirely in your browser — your inputs never leave your device, and nothing is uploaded or stored.
