What Is an EMI Calculator?
An EMI (Equated Monthly Installment) calculator tells you the fixed amount you will pay each month to repay a loan over its term. Each installment covers part of the interest and part of the principal, so by the end of the tenure the loan is fully cleared. This tool works for any reducing-balance loan — home loans, car loans, personal loans or business loans — and is currency-agnostic.
How to Use It
Enter three values: the loan amount (principal you borrow), the annual interest rate as a percentage, and the tenure in months. The calculator instantly returns your monthly EMI along with the total interest you will pay and the grand total (principal plus interest) over the life of the loan.
The Formula Explained
The standard EMI formula is $$\text{EMI} = P \cdot \frac{r\,(1+r)^{n}}{(1+r)^{n}-1}$$ Here P is the principal, n is the number of monthly installments, and r is the monthly interest rate — the annual rate divided by 12 and then by 100. If the rate is 0%, EMI is simply the principal divided by the number of months.
Worked Example
Suppose you borrow 100,000 at 10% annual interest for 12 months. The monthly rate \(r = 10/12/100 = 0.0083333\). Then \((1+r)^{12} \approx 1.104713\). $$\text{EMI} = 100000 \times 0.0083333 \times \frac{1.104713}{1.104713 - 1} \approx 8{,}791.59$$ per month. Over 12 months you pay about 105,499 in total, of which roughly 5,499 is interest.
FAQ
Does a longer tenure lower my EMI? Yes — spreading repayment over more months reduces each installment, but you pay more total interest.
Is the interest rate monthly or annual? Enter the annual rate; the calculator converts it to a monthly rate internally.
Does this include processing fees or insurance? No. It computes the pure loan EMI based on principal, rate and tenure only.
