Calculation Formulas

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
ROI Calculation Method:
The ROI is calculated using a binary search algorithm that finds the interest rate where:
EMI = [P × r × (1 + r)^n] / [(1 + r)^n – 1]
The algorithm iteratively adjusts the interest rate until the calculated EMI matches the provided EMI amount.

About EMI

  • EMI stands for Equated Monthly Installment
  • Includes both principal and interest components
  • Remains constant throughout the loan tenure
  • Early in the loan, more of your payment goes toward interest

Smart Tips

  • Shorter tenures mean higher EMIs but lower total interest
  • Even small increases in EMI can significantly reduce loan tenure
  • Compare rates from multiple lenders before borrowing
  • Consider prepayment options to save on interest

Common Mistakes

  • Not accounting for processing fees and other charges
  • Focusing only on EMI without considering total interest
  • Not comparing floating vs. fixed interest rates
  • Overlooking prepayment penalties
