EMI (Equated Monthly Instalment) is the fixed monthly payment you make to your lender to repay a loan over a set period. Each EMI comprises two components: a portion that repays the principal and a portion that covers the interest.
📐 The EMI Formula
EMI = P × r × (1 + r)^n / [(1 + r)^n – 1]
- P = Principal loan amount
- r = Monthly interest rate (annual rate ÷ 12)
- n = Loan tenure in months
Example: A ₹10,00,000 home loan at 8.5% per annum for 20 years has an EMI of approximately ₹8,678/month. Over 20 years, you pay ₹20,82,720 total — ₹10,82,720 as interest.
📊 Factors That Affect Your EMI
- Principal amount: Higher loan = higher EMI
- Interest rate: Even 0.5% difference significantly impacts EMI over long tenures
- Loan tenure: Longer tenure = lower EMI but higher total interest paid
- Type of interest: Flat rate vs reducing balance (always compare on reducing balance)
💡 How to Reduce Your EMI
- Make a larger down payment — reduces the principal
- Negotiate a lower interest rate — check your CIBIL score first
- Extend the loan tenure — but remember you’ll pay more total interest
- Make partial prepayments — reduces outstanding principal, lowering future EMIs
- Balance transfer — switch to a lender offering lower rates
📈 EMI Amortization: Principal vs Interest Over Time
In the early months of a loan, a larger portion of your EMI goes toward interest. As the loan progresses, more goes toward principal. This is called amortization and is why prepaying early in the loan tenure saves significantly more interest than prepaying later.
