EMI Formula#

EMI is calculated using this 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

Tips for Borrowers#

Lower Your EMI#

  • Longer tenure reduces EMI but increases total interest
  • Larger down payment reduces principal
  • Better credit score may get lower interest rates

Reduce Total Interest#

  • Shorter tenure means less interest
  • Part prepayments reduce principal faster
  • Floating to fixed rate conversion when rates drop

Before Taking a Loan#

  1. Check your credit score
  2. Compare offers from multiple lenders
  3. Read all terms and conditions
  4. Calculate total cost including processing fees
  5. Ensure EMI is within 40% of income
