Planning a loan? Your EMI (Equated Monthly Instalment) is the monthly amount you’ll pay. This guide explains the formula in simple steps, shows real Indian examples, and gives you a calculator to do it instantly.
What is EMI and why it matters
EMI is the fixed monthly amount you repay on a loan. It helps you compare banks, choose tenure, and keep your budget predictable.
EMI formula (snippet target)
EMI = P × r × (1 + r)^n / ((1 + r)^n − 1)
Where:
- P = Principal (₹)
- r = monthly interest rate (annual ÷ 12)
- n = total months (years × 12)
💡 Quick tip: Annual 8.5% → monthly r = 0.085 / 12 ≈ 0.0070833
Step-by-step: How to calculate EMI by hand
- Convert annual rate to monthly: r = annual ÷ 12
- Convert years to months: n = years × 12
- Plug into the formula and solve powers first
- Round to nearest rupee
Prefer Excel/Sheets? Use:
=PMT(annual_rate/12, months, -principal)
Example: =PMT(8.5%/12, 240, -3000000)

Worked examples (India-style scenarios)
1) Home loan
- P = ₹30,00,000
- Annual rate = 8.5%
- Tenure = 20 years (n = 240 months)
- EMI ≈ ₹26,035
- Total payment ≈ ₹62,48,327
- Total interest ≈ ₹32,48,327
2) Personal loan
- P = ₹5,00,000
- Annual rate = 12%
- Tenure = 5 years (n = 60 months)
- EMI ≈ ₹11,122
- Total payment ≈ ₹6,67,333
- Total interest ≈ ₹1,67,333
3) Car loan
- P = ₹8,00,000
- Annual rate = 9.5%
- Tenure = 7 years (n = 84 months)
- EMI ≈ ₹13,075
- Total payment ≈ ₹10,98,316
- Total interest ≈ ₹2,98,316

Choosing the right tenure (fast rules)
- Lower EMI = longer tenure → you’ll pay more total interest
- Higher EMI = shorter tenure → less total interest
- Try to keep EMI ≤ 35–40% of your net monthly income
Common mistakes to avoid
- Comparing EMIs without the same tenure/rate assumptions
- Ignoring processing fees and prepayment rules
- Using annual rate directly in formula (must use monthly)

EMI = P × r × (1+r)^n / ((1+r)^n − 1), with monthly r and n in months.
Q2. How do I calculate EMI in Excel?
Use =PMT(annual_rate/12, months, -principal) — the result is your EMI.
Q3. Can I reduce my EMI during the tenure?
Yes, via part-prepayment or by increasing tenure, depending on lender rules.
Q4. Which tenure is best for home loans?
