EMI Calculator

How to use EMI Calculator

1. Enter the loan amount, annual interest rate and tenure in years.
2. Read the EMI, the total interest and the year-by-year outstanding balance.
3. Compare tenures: note how much the total interest changes while the EMI barely does.
4. The rate is annual; the calculation converts it to a monthly rate internally.
5. Total interest, not the EMI, is the figure that shows what a loan actually costs.
6. Processing fees, insurance and stamp duty are not included.

What the EMI formula is doing

EMI = P × r × (1+r)ⁿ / ((1+r)ⁿ − 1), where r is the monthly rate and n the number of months. It solves for the constant payment that clears the loan exactly at the end of the term. The instalment stays the same every month, but its composition does not: early payments are mostly interest and late ones mostly principal, which is why the balance barely moves in the first years and why prepaying early saves so much more than prepaying late.

Longer tenure, smaller EMI, far more interest

This is the trade the EMI figure alone hides. A ₹10 lakh loan at 9% over 10 years is about ₹12,668 a month and ₹5.2 lakh of interest. Stretch it to 20 years and the EMI falls to roughly ₹8,997 — comfortable — while total interest rises to about ₹11.6 lakh, more than the loan itself. Lenders present the lower EMI because it sells; the total interest is the number to compare, and it is usually one screen further in.

Prepayment is worth most in the early years

Because early instalments are mostly interest, a lump sum paid in year two removes far more future interest than the same sum in year twelve. Reducing the tenure rather than the EMI saves considerably more, and most Indian lenders let you choose — though you often have to ask. Floating-rate home loans to individuals cannot carry a prepayment penalty under RBI rules; fixed-rate loans and most personal loans can, so check before planning around it.

What the EMI figure leaves out

Processing fees, documentation and legal charges, and insurance that is sometimes bundled in without being obvious. For home loans, add stamp duty and registration, which vary by state and are not financed. Ask the lender for the Key Facts Statement: it must show the annual percentage rate with these charges included. Compare lenders on the total cost of credit rather than the headline rate, and treat a rate that is markedly below the market as an invitation to read the fee schedule carefully.
