How the Interest Rate Calculator Works
This calculator estimates the interest rate that would produce the entered EMI for the selected principal and repayment period.
- Enter the loan principal, monthly EMI, and tenure in months.
- The calculator solves the standard EMI formula for the monthly interest rate.
- The monthly rate is converted to a nominal annual rate by multiplying it by 12.
- Total payment is calculated as EMI × number of payments.
- Total interest is total payment minus the original principal.
