EMI Calculator: How to Calculate Your Loan EMI (Step-by-Step)

An EMI (Equated Monthly Installment) is the fixed monthly payment you make to repay a loan. Understanding how EMI is calculated helps you plan your finances better and choose the right loan product.

The EMI Formula

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

Where: - **P** = Principal loan amount - **r** = Monthly interest rate (annual rate / 12 / 100) - **n** = Number of monthly installments (loan tenure in months)

Example: ₹10 Lakh Personal Loan

At 10.50% for 36 months: - **Monthly EMI**: ₹32,502 - **Total Interest**: ₹1,70,072 - **Total Payment**: ₹11,70,072

At 10.50% for 60 months: - **Monthly EMI**: ₹21,494 - **Total Interest**: ₹2,89,673 - **Total Payment**: ₹12,89,673

The 5-year tenure has a lower EMI (₹11,008 less per month) but costs ₹1,19,601 more in total interest!

Tips for EMI Planning

1. **Keep total EMIs under 40% of income**: Banks use this as a key eligibility criterion
2. **Choose shorter tenure for lower total cost**: Even 6 months shorter can save thousands in interest
3. **Consider prepayment**: Making occasional prepayments reduces both tenure and total interest
4. **Factor in processing fees**: A ₹5,000-₹15,000 one-time cost that affects your true loan cost
5. **Compare EMIs across banks**: A 0.25% rate difference on ₹10 lakh over 5 years = ₹8,000 savings
