An EMI calculator works out the fixed monthly instalment on a loan from the loan amount, interest rate, and tenure, using the reducing-balance method. It also shows the total interest and total repayment, so you can see what the loan costs before you sign.

Smart Insights
Generated from the numbers you entered — no guesswork.
- You will pay ₹24,22,726 in total interest on a ₹25,00,000 loan.
- Interest accounts for 49% of everything you repay (₹49,22,726).
- Your balance drops below half the loan around year 13 — earlier years are interest-heavy.
- Repaying in 14 years instead of 18 would raise the instalment to ₹25,642 but save about ₹6,14,832 in interest.
- Adding one extra instalment a year is a low-effort way to cut both tenure and interest.
How does the EMI Calculator work?
Each step the calculator runs, in plain language.
- 1
Convert the annual rate to a periodic rate
The advertised annual rate is divided by the number of instalments in a year, then by 100. An 8.6% annual rate becomes 0.007167 per month.
- 2
Count the total instalments
Tenure in years is multiplied by the instalment frequency, so 18 years of monthly payments equals 216 instalments.
- 3
Apply the EMI formula
The formula spreads principal and interest into one fixed payment, so the amount you pay stays level throughout the loan.
- 4
Split each instalment by reducing balance
Interest is charged on the outstanding balance, so early instalments are interest-heavy and later ones repay far more principal.
EMI Calculator formula
The exact maths behind every number on this page.
EMI = P × r × (1 + r)^n ÷ ((1 + r)^n − 1)
- P
- Principal — the loan amount you borrow
- r
- Interest rate per instalment (annual rate ÷ 12 ÷ 100)
- n
- Total number of instalments (years × 12)
Banks use the reducing-balance method, so interest is charged only on the outstanding principal each period.
EMI Calculator calculation example
A ₹25,00,000 home loan at 8.6% for 18 years, repaid monthly.
- 1Principal (P)₹25,00,000
- 2Monthly rate (r)8.6 ÷ 12 ÷ 100 = 0.007167
- 3Instalments (n)18 × 12 = 216
- 4EMI₹22,790 (approx.)
You repay about ₹49.2 lakh in total, of which roughly ₹24.2 lakh is interest.
Important assumptions
What this calculation includes, and what it leaves out.
- The interest rate stays the same for the whole tenure and every instalment is paid on time — a floating-rate loan will re-price when the lender resets it.
- Interest is charged on the reducing balance, the convention Indian banks and NBFCs use for retail loans.
- Only principal and interest are included. Processing fees, insurance, stamp duty, GST on charges, and prepayment penalties are not part of the EMI shown here.
- The repayment schedule is grouped by year from the first instalment, not by financial year, so lender statements may split the same interest slightly differently.

Financial tips
Practical guidance to act on your result.
- Even one extra EMI per year can cut a 20-year loan by 3–4 years.

- Keep total EMIs under 40% of your take-home pay to stay comfortable.
- Compare offers on total interest payable, not just the headline rate.
