Whether you're planning to take a home loan, car loan, or personal loan, understanding how EMI (Equated Monthly Installment) is calculated gives you the power to compare offers and plan your finances better. In this comprehensive guide, we'll walk you through the exact formula banks use and show you how to calculate EMI step by step.
What is EMI?
EMI (Equated Monthly Installment) is the fixed amount you pay to your lender every month to repay your loan. It includes both the principal amount and the interest, calculated in such a way that the loan is fully repaid over the specified tenure.
The EMI Formula
Standard EMI Formula:
Where:
- P = Principal loan amount
- R = Monthly interest rate (Annual rate ÷ 12 ÷ 100)
- N = Number of monthly installments (Tenure in months)
Step-by-Step EMI Calculation
Example: Home Loan EMI Calculation
Loan Amount (P)
₹25,00,000
Annual Interest Rate
8.5%
Loan Tenure
20 years
Step 1: Convert annual interest rate to monthly
R = 8.5% ÷ 12 ÷ 100 = 0.00708333
Step 2: Convert years to months
N = 20 years × 12 = 240 months
Step 3: Calculate (1 + R)^N
(1 + 0.00708333)^240 = 5.4274
Step 4: Apply the EMI formula
EMI = [25,00,000 × 0.00708333 × 5.4274] / [5.4274 - 1]
EMI = [96,067] / [4.4274] = ₹21,697
Result:
Monthly EMI = ₹21,697
EMI Calculation for Different Loan Types
Car Loan Example
Loan Amount: ₹8,00,000
Interest Rate: 9.0% per annum
Tenure: 5 years (60 months)
EMI = ₹16,608
Personal Loan Example
Loan Amount: ₹5,00,000
Interest Rate: 14.0% per annum
Tenure: 3 years (36 months)
EMI = ₹17,073
Important Tips for EMI Calculation
- 💡Use a calculator for precision: Manual calculation can have rounding errors. Always verify with a reliable EMI calculator.
- 💡Consider processing fees: Banks charge 1-3% processing fee which increases your effective cost.
- 💡Fixed vs Floating rates: The formula works for fixed rates. Floating rates will change your EMI over time.
- 💡Prepayment impact: Making prepayments reduces your principal and can significantly reduce total interest.
