What is EMI? How is it Calculated?
An Equated Monthly Instalment (EMI) is the fixed amount you pay to your lender every month until your loan is fully repaid. It consists of two components: the principal amount and the interest charged on the outstanding balance.
EMI Formula
The standard formula used by all banks and financial institutions in India:
EMI = P × r × (1+r)ⁿ / [(1+r)ⁿ – 1]
Where P = Principal loan amount, r = Monthly interest rate (annual rate ÷ 12 ÷ 100), and n = Total number of monthly instalments (tenure in years × 12).
Types of Loans You Can Calculate
- Home Loan: Typically 8.5%–10.5% p.a. for tenures up to 30 years
- Car Loan: Typically 7.5%–13% p.a. for tenures up to 7 years
- Personal Loan: Typically 10.5%–24% p.a. for tenures up to 5 years
- Education Loan: Typically 8%–15% p.a. for tenures up to 15 years
Tips to Reduce Your EMI
- Make a larger down payment to reduce the principal
- Opt for a longer tenure (note: this increases total interest)
- Negotiate a lower interest rate with your bank
- Consider balance transfer to a bank offering lower rates
- Make occasional prepayments to reduce outstanding principal
Frequently Asked Questions
For floating rate loans, yes. If your bank's interest rate increases (linked to RBI repo rate), either your EMI increases or your tenure extends. For fixed rate loans, the EMI stays constant throughout the tenure.
Financial experts recommend that your total EMI obligations should not exceed 40-50% of your monthly take-home salary. For example, if you earn ₹60,000/month, your total EMIs (all loans combined) should ideally stay below ₹24,000–30,000.
