What is a Loan EMI?

An Equated Monthly Installment (EMI) is a fixed payment amount made by a borrower to a lender at a specified date each calendar month. EMIs are applied to both interest and principal each month, so that over a specified number of years, the loan is paid off in full.

Understanding your monthly payment commitments before signing a loan agreement is critical for sound budget planning. Calculate your parameters instantly using our free [EMI Loan Calculator](/tools/emi-calculator).

The EMI Mathematical Formula

The mathematical formula used to calculate EMI is:

EMI = [P x R x (1+R)^N] / [(1+R)^N - 1]

Where:

  • P = Principal Loan Amount
  • R = Monthly Interest Rate (Annual rate divided by 12 and then divided by 100)
  • N = Loan Tenure in Months

Step-by-Step Guide to Manage Your Debt

  • Keep interest rates low: Check with multiple banks to get the lowest possible annual rate.
  • Choose a suitable tenure: A longer tenure decreases your monthly EMI but increases the total interest paid over the life of the loan.
  • Make prepayments: Whenever possible, make lump sum prepayments to reduce the outstanding principal and save on interest.
