Quick answers
What is an EMI?
An EMI, or equated monthly instalment, is the fixed amount you pay every month until a loan is fully cleared. Each instalment covers the interest charged that month first, and whatever is left reduces the amount you still owe.
How is monthly interest calculated on a private loan?
Private lenders usually quote a rate per month rather than per year. At 3% a month on ₹80,000, the interest for one month is ₹2,400. If the interest is simple, that same ₹2,400 is charged every month. If unpaid interest is added to the balance, the next month is charged on ₹82,400 instead, and the amount owed grows faster each month.
What happens if EMIs start months after the loan?
Interest keeps accumulating during the gap, so the amount your EMI is calculated on is larger than the sum you borrowed. This calculator shows those months separately, so you can see exactly how much was added before repayment began.
Does paying a lump sum reduce the EMI?
Yes. A part payment reduces the outstanding balance, so the monthly amount needed to clear the loan in the same number of months falls. Enter the lump sum and its month, and the revised EMI appears immediately.

About this EMI calculator
This calculator works out the monthly EMI for any loan — a bank personal loan, a gold loan, or money borrowed from a friend or private lender at a monthly rate. Unlike a standard EMI calculator, it handles the things informal loans actually involve: interest quoted per month rather than per year, a month or two waived by the lender, EMIs that begin long after the money was taken, and lump sum part payments made whenever cash is available.
It answers the questions people are usually stuck on. How much of what I owe is interest? What will the amount be by the time I start paying? If I pay a large sum now, how much lower does my monthly payment become? If the lender only tells me a total, what rate is he actually charging?
