Where:
P = Loan amount (principal)
r = Monthly interest rate (annual rate/12/100)
n = Loan tenure in months
Example for ₹10L at 8.5% for 10 years:
P = 10,00,000
r = 8.5/12/100 = 0.0070833
n = 10 × 12 = 120
EMI = ₹10,607
Flat Rate EMI Formula:
EMI = (P + (P × r × n)) / n
Interest Calculation:
Total Interest = P × r × n
Monthly Interest = Total Interest / n
Key Differences:
• Reducing balance: Interest on remaining principal
• Flat rate: Interest on full principal for entire tenure
• Reducing balance saves interest over time
❓ Frequently Asked Questions
What is EMI?
EMI stands for Equated Monthly Installment. It's the fixed amount you pay each month towards your loan, which includes both principal repayment and interest.
How is EMI calculated?
EMI is calculated using the formula: EMI = [P × r × (1+r)^n] / [(1+r)^n - 1], where P is principal, r is monthly interest rate, and n is number of months.
What is reducing balance interest?
In reducing balance method, interest is calculated on the outstanding principal balance. As you pay EMIs, the principal reduces, so interest portion decreases over time.
Can I reduce my EMI?
Yes, you can reduce EMI by: 1) Increasing loan tenure, 2) Making a higher down payment, 3) Negotiating a lower interest rate, or 4) Opting for a step-up/step-down EMI plan.
What is prepayment and how does it affect EMI?
Prepayment is paying extra amount towards your loan. It reduces principal faster, which decreases total interest and can shorten loan tenure or reduce EMI.
