EMI (Equated Monthly Installment) is the fixed monthly payment you make to repay a loan. Whether it's a ₹50 lakh home loan, ₹8 lakh car loan, or ₹2 lakh personal loan — understanding exactly how your EMI is calculated helps you choose the right loan, tenure, and lender.
EMI Formula
EMI = P × r × (1+r)ⁿ ÷ [(1+r)ⁿ − 1]
Where: P = Principal, r = Monthly interest rate, n = Tenure in months
EMI Comparison by Loan Type
| Loan Type | Typical Amount | Interest Rate | Tenure | Monthly EMI |
|---|---|---|---|---|
| Home Loan | ₹50 Lakh | 8.5% | 20 years | ₹43,391 |
| Car Loan | ₹8 Lakh | 9.5% | 5 years | ₹16,797 |
| Personal Loan | ₹2 Lakh | 14% | 3 years | ₹6,834 |
| Education Loan | ₹10 Lakh | 10% | 7 years | ₹16,602 |
How Tenure Affects EMI and Total Interest
For a ₹30 lakh home loan at 8.5% interest:
| Tenure | Monthly EMI | Total Payment | Total Interest |
|---|---|---|---|
| 10 years | ₹37,154 | ₹44,58,480 | ₹14,58,480 |
| 20 years | ₹26,035 | ₹62,48,400 | ₹32,48,400 |
| 30 years | ₹23,067 | ₹83,04,120 | ₹53,04,120 |
Tips to Reduce Your EMI Burden
- Make prepayments: Even ₹5,000 extra per month can reduce a 20-year loan by 4–5 years
- Negotiate rate: A 0.5% rate reduction on ₹50L saves ₹1.7L over 20 years
- Balance transfer: If another bank offers 0.5%+ lower rate, transfer the loan
- Shorter tenure: Increase EMI by 10% and save lakhs in interest
- Use windfall: Bonus, gratuity, or tax refund for partial prepayment
Understanding Amortization
In early months, most of your EMI goes towards interest — not principal. For example, in month 1 of a ₹50L home loan at 8.5%, your EMI of ₹43,391 splits as ₹35,417 interest and only ₹7,974 principal. By month 100, it flips to more principal. This is why prepaying early saves the most interest. Use our EMI Calculator to see the full amortization schedule for your loan.
