Loan EMI Calculator
Calculate your loan EMI (equated monthly instalment), total interest, and total repayment.
An EMI, or equated monthly instalment, is the fixed amount you pay each month on a loan until it's cleared. This calculator turns a loan amount, an interest rate, and a term into your monthly payment, the total interest you'll pay, and the total amount repaid.
Seeing the interest total alongside the monthly figure is the point: two loans with the same EMI can cost very different amounts once you add up every payment.
How to use the EMI calculator
- Enter the loan amount (the principal you're borrowing).
- Enter the annual interest rate as a percentage.
- Enter the term in years.
- Read your monthly EMI, total interest, and total repayment.
How EMI is calculated
The EMI formula is 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 (years × 12).
Early payments are mostly interest; later payments are mostly principal. That's why paying a little extra in the first years saves far more than the same amount paid near the end.
Reducing what you pay
Three levers change the total cost of a loan: the rate, the term, and any extra payments. A lower rate is the obvious win. A shorter term raises the monthly payment but slashes total interest. And overpaying — even occasionally — shortens the loan because every extra dollar goes straight to principal. Try changing each field here to see how sensitive your total is to each one.
Comparing two loan offers
The EMI alone can mislead. A longer loan almost always shows a smaller monthly payment, which feels cheaper but usually isn't. To compare fairly, look at the total repayment figure this calculator shows: borrow $20,000 at 8% over five years and you pay about $4,332 in interest; stretch the same loan to eight years and the monthly payment drops, but total interest climbs well past $7,000. When you weigh offers, hold either the term or the monthly budget constant and compare the total cost, not just the headline instalment.
The value of overpaying early
Because a loan front-loads interest, extra payments in the first years are unusually powerful — every additional dollar goes straight to principal and removes all the future interest that principal would have generated. Even one extra payment a year can shave months or years off the term. Try lowering the term field here to see the monthly payment that would clear the debt sooner, then decide whether that stretch is worth the interest saved.
Frequently asked questions
What does EMI mean?
EMI stands for equated monthly instalment — the fixed monthly payment that covers both interest and principal until a loan is fully repaid.
Does a longer term make a loan cheaper?
It lowers the monthly payment but raises the total interest, so the loan usually costs more overall. A shorter term does the opposite.
Is this the same as an amortization calculator?
It uses the same amortization formula to find your EMI and totals. It shows the summary figures rather than a full month-by-month schedule.
Does it include fees or insurance?
No. It calculates principal and interest only. Add any origination fees, insurance, or taxes separately for a full picture.
Why is my early EMI mostly interest?
Interest is charged on the outstanding balance, which is largest at the start. So early payments cover mostly interest and little principal. As the balance falls, the split shifts toward principal.
