EMI Calculator — How to Calculate Your Loan EMI

Before taking any loan, the first question everyone asks is: "What will be my monthly EMI?" Understanding your EMI helps you plan your budget and choose the right loan tenure.

What is EMI?

EMI stands for Equated Monthly Instalment. It's the fixed amount you pay to the bank every month until the loan is fully repaid. Your EMI includes both principal repayment and interest charges.

EMI Formula

The standard EMI formula is:

EMI = P × r × (1 + r)^n / ((1 + r)^n − 1)

Where:

  • P = Principal loan amount
  • r = Monthly interest rate (annual rate ÷ 12 ÷ 100)
  • n = Loan tenure in months

Example Calculation

For a ₹10,00,000 home loan at 8.5% for 20 years:

  • P = ₹10,00,000
  • r = 8.5 / 12 / 100 = 0.00708
  • n = 240 months

EMI = ₹8,678/month

Total payment: ₹20,82,720 (you pay ₹10,82,720 in interest!)

How Tenure Affects Your EMI

| Loan Amount | Rate | 10 Years | 15 Years | 20 Years | 25 Years | |---|---|---|---|---|---| | ₹10L | 8.5% | ₹12,399 | ₹9,847 | ₹8,678 | ₹8,054 | | ₹25L | 8.5% | ₹30,997 | ₹24,617 | ₹21,694 | ₹20,134 | | ₹50L | 8.5% | ₹61,993 | ₹49,234 | ₹43,389 | ₹40,269 |

Key insight: A longer tenure means lower EMI, but much higher total interest. A 20-year loan at 8.5% costs you more than double the principal in interest.

Tips to Reduce Your EMI

  1. Negotiate the interest rate — Compare offers from 3-4 banks
  2. Make a larger down payment — Reduces the principal, which reduces EMI
  3. Choose a shorter tenure — Higher EMI but much less total interest
  4. Prepay when possible — Even small prepayments reduce total interest significantly
  5. Transfer to a lower-rate bank — Balance transfer saves thousands over the loan term
