Loan / EMI Calculator
Enter your loan amount, annual interest rate, and tenure to estimate your monthly EMI, total payment, and total interest.
How to use the Loan / EMI Calculator
Enter the loan amount, annual interest rate, and loan tenure (in months or years), then calculate. The tool instantly estimates your monthly EMI (equated monthly installment), along with the total amount you'll pay and the total interest over the life of the loan.
What is EMI?
An EMI (Equated Monthly Installment) is a fixed payment made each month toward repaying a loan, covering both principal and interest. EMIs are commonly used for home loans, car loans, and personal loans, letting borrowers repay a large amount in predictable, manageable installments over time.
Frequently asked questions
What formula is used to calculate EMI?
The standard EMI formula is: EMI = [P × r × (1+r)^n] / [(1+r)^n - 1], where P is the principal loan amount, r is the monthly interest rate (annual rate ÷ 12), and n is the number of monthly installments.
Does a longer tenure always mean I pay less?
A longer tenure lowers your monthly EMI but increases the total interest paid over the life of the loan, since interest accrues for a longer period. A shorter tenure means higher EMIs but less total interest.
Is this calculator accurate for my bank's exact EMI?
This calculator gives a close estimate using the standard EMI formula. Your actual EMI may vary slightly depending on your lender's specific calculation method, processing fees, or rate type (fixed vs floating).

How your monthly EMI is actually calculated
An EMI (Equated Monthly Installment) is calculated so that the same fixed payment covers both interest and principal over the loan's full term, using the loan amount, annual interest rate, and tenure. Early in a loan, a larger share of each payment goes toward interest, and a smaller share toward principal; that ratio flips as the loan matures — which is why paying off a loan a few years early saves more in interest than people often expect.
What changes your total interest cost
Three levers determine how much you'll pay in total: the loan amount, the interest rate, and the tenure. Extending the tenure lowers your monthly payment but increases total interest paid, since you're borrowing the bank's money for longer. Even a 1% difference in interest rate can add up to a meaningful sum over a 15-20 year loan, which is why comparing offers from multiple lenders before committing is worth the time.
Common uses
Comparing loan offers before signing, deciding between a shorter tenure with higher payments versus a longer one with lower payments, checking whether a planned purchase fits your monthly budget, and estimating how much extra you'd need to pay monthly to close a loan early are all typical reasons people run these numbers.
