The calculator uses the standard EMI 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 installments. All math runs instantly in your browser as you move the sliders.

Frequently Asked Questions

What is EMI and how is it calculated?

EMI (Equated Monthly Installment) is the fixed amount you pay your lender each month until the loan is repaid. It is calculated with the formula EMI = P × r × (1+r)^n / ((1+r)^n − 1). For example, a ₹10,00,000 loan at 9% for 20 years gives an EMI of about ₹8,997.

Does a longer tenure reduce my EMI?

Yes — extending the tenure lowers the monthly EMI but increases the total interest you pay. On a ₹10 lakh loan at 9%, moving from 10 to 20 years cuts the EMI from ₹12,668 to ₹8,997, but total interest jumps from ₹5.2 lakh to ₹11.6 lakh.

Is the EMI calculator really free?

Yes — 100% free with no hidden charges, trial limits, or premium tiers for core features. You don't need to create an account or enter an email address. The site is supported by non-intrusive display ads, which keeps every tool free for everyone.
