Question

How to calculate EMI?

Answer 1

An Equated Monthly Instalment (EMI) is usually a fixed amount of money that you need to pay your bank or lender every month as repayment of a loan taken, until your loan is totally repaid. It is essentially made up of two parts, the principal amount and the interest on the principal amount, divided across each month of the loan tenure. The EMI is always paid to the bank or lender on a fixed date each month. This could be done though post-dated cheques issued in favour of the lender or by providing auto debit instructions to your bank for the same.
Here’s the formula to calculate an EMI:
EMI = [P x I x (1+I)^N]/[(1+I)^N-1], where P is the loan amount or Principal, I is the Interest rate per month. [To calculate rate per month: if the interest rate per annum is 14%, the per month rate would be 14/(12 x 100)], and N is the number of instalments.

Answer 2

[P x R x (1+R)^N]/[(1+R)^N-1] is the formula for calculating Emi where 
P is for Principal or the amount to be paid.
R is for the rate of interest per month.
N is the number of months in which you pay the money.
