What is EMI?


EMI (Equated Monthly Instalment) is the fixed monthly payment you make to repay a loan over a set tenure. Every EMI consists of two parts: a principal component and an interest component. In the early months of a loan, a larger portion goes toward interest. Over time, the principal component increases.

EMI Calculation 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 = Loan tenure in months

Worked Example

Suppose you take a home loan of ₹30,00,000 at an annual interest rate of 8.5% for 20 years (240 months):

– Monthly rate R = 8.5 ÷ 12 ÷ 100 = 0.00708
– EMI = [30,00,000 × 0.00708 × (1.00708)^240] ÷ [(1.00708)^240 − 1]
– Monthly EMI ≈ ₹26,035
– Total Payment = ₹62,48,400
– Total Interest = ₹32,48,400

  1. What is the EMI formula?

    EMI = [P × R × (1 + R)^N] ÷ [(1 + R)^N − 1], where P is the principal, R is the monthly interest rate (annual rate ÷ 12 ÷ 100), and N is the loan tenure in months.

  2. How do I reduce my loan EMI?

    You can reduce your EMI by: (1) increasing the loan tenure, (2) making a larger down payment to reduce the principal, (3) negotiating a lower interest rate, or (4) prepaying a lump sum to reduce the outstanding principal.

  3. Does paying extra EMI reduce loan tenure?

    Yes. Making prepayments — extra payments beyond your regular EMI — reduces your outstanding principal. This either shortens your loan tenure or reduces future EMIs, depending on your bank’s policy.

  4. What is the difference between fixed and floating EMI?

    Fixed-rate EMIs remain constant throughout the loan tenure. Floating-rate EMIs change with market interest rates (linked to RBI repo rate or MCLR). Fixed rates offer predictability; floating rates may save money if rates fall.

  5. How much EMI can I afford?

    A commonly followed rule is that your total EMI obligations should not exceed 40–50% of your monthly take-home salary. For example, if your salary is ₹60,000/month, your total EMIs should ideally not exceed ₹24,000–₹30,000.

  6. Is EMI calculated on the original loan amount or outstanding balance?

    EMI is calculated on the reducing balance method — meaning interest is charged only on the outstanding principal, not the original loan amount. This is why your interest component decreases over time while the principal component increases.
