An EMI (equated monthly instalment) is the fixed amount you pay each month on a loan until it's cleared. Each payment covers that month's interest and pays down part of the loan. This calculator works out the instalment for a car, home, business or personal loan and shows how much the loan really costs over its life.
How it works
The standard formula is EMI = P × r × (1 + r)ⁿ ÷ ((1 + r)ⁿ − 1), where P is the amount borrowed, r is the monthly rate (the annual rate ÷ 12) and n is the number of monthly payments.
Early payments are mostly interest, because interest is charged on the full balance. As the balance falls, more of each fixed instalment goes to the loan itself. The first-payment figure shows how front-loaded the interest is.
Total interest is every payment added up, minus the amount borrowed. A longer term lowers the monthly instalment but raises the total interest, often by a lot.
Banks may add processing fees, insurance or taxes that aren't part of this formula. Ask for the full cost of the loan, including the annual percentage rate (APR), before you sign.
A worked example
You borrow $25,000 at 9% a year over 5 years. The monthly rate is 0.75% and there are 60 payments, so the EMI is $518.96. Over five years you pay $31,137.53 in total, of which $6,137.53 is interest. The first payment alone includes $187.50 of interest.
Questions people ask
How is EMI calculated?
EMI = P × r × (1 + r)ⁿ ÷ ((1 + r)ⁿ − 1). P is the loan amount, r is the annual rate divided by 12 (as a decimal), and n is the number of months. The calculator shows every step with your numbers.
Is a longer loan term better?
It lowers the monthly payment but increases total interest. On $25,000 at 9%, stretching from 5 to 7 years cuts the EMI from $518.96 to $402.23 but adds about $2,650 of interest. Choose the shortest term whose payment you can comfortably afford.
Does this work for Islamic financing such as murabaha or ijara?
Many Islamic banks quote a fixed annual profit rate and a fixed monthly instalment, which follows the same arithmetic, so the result is a useful estimate. The contract structure, fees and early-settlement rules differ from a conventional loan, so confirm the final figures with the provider.
What happens if I pay extra or settle the loan early?
Extra payments usually reduce the outstanding balance, which cuts future interest. Some lenders charge an early settlement or prepayment fee, so check the terms first.
Is the interest rate the same as the APR?
Not always. The interest rate covers interest only. The APR also includes fees, so it shows the true yearly cost. Compare loans on APR, then use the interest rate here to plan the monthly payment.
