What Is an EMI and How Is It Calculated?
EMI (Equated Monthly Instalment) is the fixed amount you pay every month to repay a loan. Each EMI usually includes both principal (the amount borrowed) and interest charged by the lender.
Whether you have a home loan, personal loan, car loan, or education loan, understanding your EMI can help you plan your monthly budget.
How Is EMI Calculated?
The standard EMI formula is:
EMI = P × R × (1 + R)ⁿ ÷ [(1 + R)ⁿ − 1]
Where:
- P = Principal loan amount
- R = Monthly interest rate
- N = Total number of monthly instalments
For example, suppose you borrow ₹5 lakh at an annual interest rate of 10% for 5 years.
The monthly interest rate is approximately 0.833%, and the loan has 60 monthly instalments.
Your EMI would be approximately ₹10,624 per month.
What Determines Your EMI?
Your EMI mainly depends on three things:
1. Loan Amount
A larger loan generally means a higher EMI, assuming the interest rate and tenure remain the same.
2. Interest Rate
A higher interest rate generally increases your monthly EMI and the total interest paid over the loan period.
3. Loan Tenure
A longer tenure can reduce your monthly EMI, but you may end up paying more total interest because the loan remains outstanding for longer.
EMI Example
For a ₹5 lakh loan at 10% per year for 5 years:
Particular Amount
Loan Amount ₹5,00,000
Interest Rate 10% p.a.
Tenure 5 years
Approx. EMI ₹10,624
Approx. Total Payment ₹6.37 lakh
Approx. Total Interest ₹1.37 lakh
Actual figures may vary slightly depending on the lender's calculation method and applicable charges.
How Can You Reduce Your EMI?
You can potentially reduce your monthly EMI by:
- Choosing a longer repayment tenure
- Comparing lenders for a lower interest rate
- Making a larger down payment, where applicable
- Making eligible part-prepayments to reduce the outstanding principal
However, choosing a longer tenure can increase the total interest cost.
Final Takeaway
EMI is an important part of loan planning. Before taking a loan, don't look only at the monthly EMI—also consider the interest rate, loan tenure, total interest payable, processing fees, and other applicable charges.
