What is EMI? Complete Understanding
EMI (Equated Monthly Installment) is the fixed payment amount made by a borrower to a lender at a specified date each calendar month. EMIs are used to pay off both interest and principal components of a loan each month, ensuring the loan is fully repaid by the end of the tenure.

EMI Calculation Formula Explained
📘 Info
EMI = P × r × (1 + r)n / ((1 + r)n - 1)
Where:
Step-by-Step Calculation Example
Example: ₹10,00,000 Personal Loan at 12% for 5 Years
Step 1: P = ₹10,00,000
Step 2: Annual rate = 12%, Monthly rate (r) = 12% ÷ 12 = 1% = 0.01
Step 3: n = 5 years × 12 months = 60 months
Step 4: (1 + r)n = (1.01)60 = 1.8167
Step 5: EMI = 10,00,000 × 0.01 × 1.8167 / (1.8167 - 1)
Step 6: EMI = 10,000 × 1.8167 / 0.8167 = ₹22,244
Monthly EMI = ₹22,244
5 Key Factors Affecting Your EMI
1. Loan Amount (Principal)
Higher loan amount = Higher EMI. A ₹10L loan has twice the EMI of ₹5L loan at same rate and tenure.
Example: ₹5L → ₹11,122 EMI | ₹10L → ₹22,244 EMI
2. Interest Rate
Higher interest rate = Higher EMI. Even 1% difference matters significantly over long tenure.
Example: 8% → ₹20,276 | 9% → ₹22,244 (₹1,968 more per month)
3. Loan Tenure
Longer tenure = Lower EMI but More total interest. Shorter tenure = Higher EMI but Less total interest.
20 years: ₹44,986 | 15 years: ₹50,722 | 30 years: ₹40,233
4. Credit Score
Higher credit score (750+) qualifies for lower interest rates, reducing EMI.
750+ score: 8.5% rate | Below 650: 10.5%+ rate
5. Down Payment (for secured loans)
Higher down payment = Lower loan amount = Lower EMI. 20% down payment reduces EMI by 20%.
Loan Prepayment: When & How Much to Prepay
✅ Good to Know
💡 The Magic of Prepayment
Prepaying even small amounts early in the loan tenure can save massive interest. Every ₹1,000 prepaid in Year 1 saves ₹2,000-3,000 in interest over the loan life.
Prepayment Impact Example
| Prepayment Amount | When | Interest Saved | Tenure Reduction |
|---|---|---|---|
| ₹1,00,000 | Year 1 | ₹2,50,000 | 12 months |
| ₹1,00,000 | Year 5 | ₹1,80,000 | 8 months |
| ₹1,00,000 | Year 10 | ₹90,000 | 4 months |
| ₹1,00,000 | Year 15 | ₹30,000 | 1.5 months |
💡 Pro Tip
⚠️ Prepayment Charges to Know
- Floating rate home loans: No prepayment charges
- Fixed rate loans: 2-3% prepayment penalty
- Personal loans: Prepayment allowed after 6-12 months
- Car loans: Usually 3-5% prepayment charge
FOIR Ratio: How Banks Calculate Loan Eligibility
What is FOIR?
Fixed Obligation to Income Ratio (FOIR) is the percentage of your monthly income that goes toward loan EMIs. Banks typically allow 40-50% of income for EMIs.
📘 Info
FOIR = (Total Monthly EMIs / Monthly Income) × 100
Eligibility Example
Monthly Income: ₹1,00,000
Existing EMIs: ₹20,000
Max allowed FOIR: 50%
Available for new loan: ₹30,000 per month
Maximum loan amount at 9% for 20 years: ₹33 Lakhs
15 Common EMI Mistakes to Avoid
Frequently Asked Questions
Q: What is the difference between EMI and simple interest?
EMI includes both principal and interest, while simple interest is calculated only on principal. EMI is used for most loans (home, car, personal), while simple interest is used for short-term loans and some fixed deposits.
Q: Can I reduce my EMI after taking a loan?
Yes, by: 1) Loan balance transfer to lower rate lender, 2) Making prepayment (reduces outstanding, bank may recalculate EMI), 3) Negotiating with existing lender for rate reduction
Q: What happens if I miss an EMI payment?
Missed EMI results in: Late payment fees (2-3% per month), Negative credit score impact (CIBIL score drops 50-100 points), Loan becoming NPA after 90 days, Legal action from lender. Always inform bank before missing EMI.
Q: Is it better to prepay or invest surplus money?
Compare loan interest rate vs expected investment returns. If loan rate > investment returns → Prepay. If investment returns > loan rate → Invest. For home loans (8-9%), investing in equity (12-15% returns) may be better mathematically.
Q: How does part-payment affect EMI?
Part-payment reduces outstanding principal. You have two options: 1) Keep EMI same → Tenure reduces, 2) Keep tenure same → EMI reduces. Option 1 saves more total interest.
Q: What is the maximum EMI I can afford?
Banks use 40-50% FOIR rule. Your total EMIs (existing + new) should not exceed 40-50% of monthly income. For example, ₹1,00,000 income → Max ₹40,000-50,000 total EMIs.
