What is EMI?
EMI (Equated Monthly Installment) is the fixed amount you pay every month to repay a loan. It includes both principal and interest, spread evenly across the loan tenure.
EMI Formula
EMI = P × r × (1+r)^n / [(1+r)^n - 1]
- P = Principal loan amount
- r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
- n = Loan tenure in months
Example Calculation
Let's say you take a home loan of:
- Loan amount: ₹5,00,000
- Interest rate: 8.5% per year
- Tenure: 60 months (5 years)
Monthly rate = 8.5 ÷ 12 ÷ 100 = 0.00708
EMI = 5,00,000 × 0.00708 × (1.00708)^60 ÷ [(1.00708)^60 - 1]
EMI ≈ ₹10,268/month
Total payment = ₹6,16,080
Total interest = ₹1,16,080
Factors That Affect Your EMI
- Loan amount: Higher amount = higher EMI
- Interest rate: Even 0.5% difference can save lakhs over 20 years
- Tenure: Longer tenure = lower EMI but more total interest
- Down payment: Larger down payment = smaller loan = lower EMI
- Prepayments: Partial prepayments reduce principal and total interest
Tips to Reduce Your EMI
- Negotiate for lower interest rates — compare 3+ banks
- Make prepayments whenever possible (even 1 extra EMI/year helps)
- Choose shorter tenure if you can afford higher EMI
- Improve your credit score (750+) for better rates
- Consider balance transfer to a bank offering lower rates
