How to Calculate EMI in 2 minutes

If you are thinking about taking a loan — whether it is a Home Loan, Car Loan, Education Loan, Vehicle Loan or any other Loan — it’s very important to understand your EMI(Equated Monthly Installment) and then calculate emi. By knowing your EMI helps you to make better financial decisions. In this guide, I will walk you through from real-life examples and show you how to use modern tools, including my free calculator and other resources, to save your time and plan smarter.

Why you need to Learn to calculate EMI?

• Verify from both sides: Even Banks can make mistakes. So to verify their calculations.
• Easy Loan comparisons: Adjust loan variables like tenure, rate of interest to see their impact instantly.
• Financial Deicision confidence: Understand why this EMI and how it is calculated.

The Global EMI Formula is (For Fixed Interest Rates)

All fixed-rate type of Calculate EMIs are being used this formula:

EMI = [P × R × (1+R)^N] / [(1+R)^N − 1]

• P = Principal loan amount (Loan to be taken)
• R = Monthly interest rate (Annual Rate ÷ 12)
• N = Loan tenure (in months)

Step by Step Calculations are:

Example for Home Loan

Let’s calculate a ₹5000000 (₹50 lakh) home loan at 8.5% interest rate per annual. for 20 years:

1. Convert annual rate to monthly:
   R = 8.5% / 12 = 0.7083% → 0.007083 (decimal format).
2. Convert years to months:
   N = 20 × 12 = 240 months.
3. Plug into the formula:
   1. Numerator: 50,00,000 × 0.007083 × (1 + 0.007083)^240
   1. Denominator: (1 + 0.007083)^240 − 1
4. Let us calculate it step by step:
   1. (1 + R)^N = (1.007083)^240 ≈ 5.283
   1. Numerator: 50,00,000 × 0.007083 × 5.283 ≈ ₹1,87,000
   1. Denominator: 5.283 − 1 = 4.283
   1. EMI: 1,87,000 / 4.283 ≈ ₹43,650

✅ Result: Your Final EMI is ₹43,650.

💡 Pro Tip: Use Excel’s PMT function:
=PMT(8.5%/12, 240, 5000000) → ₹-43,650 (negative for cash outflow).

Variable (floating) Interest Rate Loans: The Manual Challenge

Variable rates (like floating home loans) change with market conditions. Here’s how to handle them:

Step by Step Calculations are:

Assume a ₹1000000 (₹10 lakh) loan at an initial 9% for 5 years, with the rate hiking to 10% in Year 3:

1. Calculate EMI for initial rate (Years 1–2):
   1. R = 9%/12 = 0.0075
   1. N = 5 × 12 = 60
   1. EMI = [10,00,000 × 0.0075 × (1.0075)^60] / [(1.0075)^60 − 1] = ₹20,758
2. Remaining balance after 2 years:
   1. Paid: 24 EMIs (₹20,758 × 24 = ₹4,98,192)
   1. Interest paid: Use amortization formula:
      Remaining Principal = P × [(1+R)^N – (1+R)^n] / [(1+R)^N − 1]
      = 10,00,000 × [(1.0075)^60 – (1.0075)^24] / [(1.0075)^60 − 1] ≈ ₹6,78,500
3. Recalculate the EMI for new rate (10%) and tenure (3 years):
   1. New R = 10%/12 = 0.00833
   1. New N = 36
   1. New EMI = [6,78,500 × 0.00833 × (1.00833)^36] / [(1.00833)^36 − 1] = ₹21,900

📉 Impact: A 1% rate hike increased EMI by ₹1,142.

Special Cases: Prepayments, Fees & More

Partial Prepayments

If you pay ₹2 lakh extra in Year 3 of the above loan:

• New principal = ₹6,78,500 − ₹2,00,000 = ₹4,78,500
• Now Calculate EMI with ₹4,78,500, 10% rate, and 36 months → ₹15,430.

Processing Fees

A 1% fee on ₹5000000 (₹50 lakh) adds ₹50,000 to your principal. Recalculate the EMI including this!

When Manual Math Gets Confused (Use Tools Instead!)

While manual calculations are time-consuming for:

• Variable-rate loans with frequent changes.
• Comparing 10+ loan offers in real-time.
• Compound interest projections for investments.
