What is an Equated Monthly Installment (EMI)?

An EMI is a fixed monthly payment made by a borrower to a lender on a specified date each month, consisting of both principal repayment and accrued interest.

How is the monthly reducing balance interest calculated?

Interest is calculated on the remaining outstanding principal balance each month rather than the initial borrowing amount, so the interest component decreases over time.

Can I use this for home, car, and personal loans?

Yes, this standard mathematical reducing-balance formula applies across all fixed-rate loans including home loans, auto loans, student loans, and personal loans.
