What is EMI?
EMI (Equated Monthly Instalment) is a fixed amount you pay every month to repay a loan. Each EMI contains both interest and principal. With the reducing-balance method, the interest share falls over time while the principal share rises.
EMI formula
We use the standard amortizing-loan formula with monthly compounding:
EMI = P x r x (1 + r)^n / [(1 + r)^n - 1]
Where P = loan amount, r = monthly interest rate (annual / 12 / 100), and n = total monthly instalments. If r = 0, then EMI = P / n.
Worked example
For ₹10,00,000 at 10% p.a. over 5 years (60 months):
- Monthly EMI: ~₹21,247
- Total Interest: ~₹2,74,820
- Total Payment: ~₹12,74,820
We round to the nearest rupee for display; a lender's rounding may differ slightly.
Reducing balance vs flat interest
Reducing balance EMI (used by banks/NBFCs): interest is calculated on the outstanding principal each month. The interest share drops every month.
Flat interest: interest is charged on the original principal for the entire tenure. EMI looks simple but usually costs more overall.
This calculator uses the reducing balance method.
Pre-EMI vs full EMI (home loans)
- Pre-EMI (during construction/partial disbursal): You pay interest-only on the disbursed amount - lower outgo today, but principal does not reduce.
- Full EMI: You pay principal + interest from day one - typically saves on total interest over the life of the loan.
Charges and GST - what is included in EMI?
Your EMI covers principal and interest. Lenders may also levy processing/administrative fees, documentation, late-payment, foreclosure/part-prepayment charges, etc.
In India, GST generally applies to fees/charges (e.g., processing fee), not to the principal or interest component of the EMI. Always confirm with your lender.
Factors that affect your EMI
- Interest rate (fixed vs floating)
- Tenure (months)
- Loan amount and LTV
- Credit score and income stability
- Part-prepayments / foreclosure (changes EMI/tenure and reduces interest cost)
How to reduce your EMI (practical tips)
- Choose a longer tenure (lowers EMI, increases total interest).
- Increase down payment (home/car loans).
- Improve credit score before applying.
- Pick floating when rate outlook is softening; fixed for predictability.
- Make part-prepayments; ask lender to reduce tenure to save interest.
- Refinance/balance-transfer to a lower rate after comparing total costs.
EMI for popular loan types
- Home loan EMI: Long tenures (up to 30 years) lead to lower EMI but higher total interest if rates are high.
- Car loan EMI: Typically 3-7 years; rates lower than personal loans.
- Personal loan EMI: 1-5 years; higher rates; prepayment terms vary.
