It is a fixed payment made by a borrower to a lender at a specified date each calendar month. - **Q: How is EMI calculated?** A: EMI is calculated using the formula: EMI = [P × R × (1+R)^N] / [(1+R)^N - 1], where P is the principal, R is the monthly interest rate, and N is the number of months. - **Q: Does prepayment reduce EMI?** A: Yes. Prepayment reduces your outstanding principal, which reduces the total interest paid.
