📖 Quick Definition
EMI (Equated Monthly Instalment) is the fixed monthly amount you pay to your bank or NBFC to repay your home loan. Each EMI contains two components: a portion of the principal (the loan amount) and the interest charged for that month. The split changes every month — early EMIs are mostly interest; later ones are mostly principal.

What is EMI?
EMI stands for Equated Monthly Instalment. It is the standardised monthly payment method used by banks and housing finance companies for repayment of home loans. The word "equated" means the amount remains the same every month (for fixed rate loans), making budgeting predictable for the borrower.
Every EMI payment you make contains two parts: the interest component (what the bank charges for lending money) and the principal component (which reduces your outstanding loan balance). In the early years of your loan, the interest portion dominates. As you progress, the principal portion increases — this is called loan amortisation.
EMI Formula
The standard EMI formula used by all Indian banks:
📐
EMI = P × r × (1 + r)ⁿ ÷ [(1 + r)ⁿ − 1]
Where: P = Principal loan amount r = Monthly interest rate (annual rate ÷ 12 ÷ 100) n = Total number of monthly instalments (tenure in years × 12)

EMI Prepayment Strategy
Making partial prepayments on your home loan is one of the smartest financial moves available to you. When you prepay, the entire amount goes towards reducing the principal — which reduces your future interest burden significantly.
💡
Prepayment tip: On a ₹75 lakh loan at 8.75% for 20 years, making one additional EMI payment per year can reduce your loan tenure by approximately 3–4 years and save over ₹12–15 lakh in total interest. RBI guidelines prohibit banks from charging prepayment penalties on floating rate home loans.
EMI stands for Equated Monthly Instalment. It is the fixed monthly payment made to a bank to repay a home loan. Each EMI contains two parts — a principal repayment component and an interest component. The proportion of interest decreases and principal increases over the loan tenure.
EMI = P × r × (1+r)ⁿ ÷ [(1+r)ⁿ − 1], where P is the loan amount, r is the monthly interest rate (annual rate divided by 12 and 100), and n is the total number of monthly instalments. For a ₹50 lakh loan at 8.75% for 20 years, the EMI is approximately ₹44,086 per month.
For a ₹1 crore home loan at 8.75% interest rate for a 20-year tenure, the EMI is approximately ₹88,172 per month. For a 30-year tenure at the same rate, the EMI reduces to approximately ₹78,658. You can use an online EMI calculator for precise figures based on your bank's rate.
No. As per RBI guidelines, banks and NBFCs cannot charge any prepayment penalty or foreclosure charges on floating rate home loans to individual borrowers. For fixed rate loans, some lenders may charge a prepayment penalty — check your loan agreement before prepaying.
The principal repayment component of your EMI qualifies for deduction up to ₹1.5 lakh per year under Section 80C. The interest component qualifies for deduction up to ₹2 lakh per year under Section 24(b) for self-occupied property. First-time buyers may get additional deduction under Section 80EEA subject to eligibility conditions.
