How Does a Personal Loan Calculator Work?

Easy Monthly Installment or EMI needs to be paid by you whenever you take a personal loan. Lenders use the personal loan calculator to calculate the EMI and interest rate you need to pay. In order to do that, they provide these three details on the personal loan calculator – Principal Loan Amount, which is the amount of borrowed money, Loan Tenure, which is the time period for which the loan is sanctioned, and Interest Rate, which is the rate of interest levied on the principal loan amount.

Once lenders put these three parameters on the personal loan calculator, it shows the EMI amount that needs to be paid each month by you. Here is the formula through which lenders calculate the EMI:

Personal Loan EMI = [P* R* (1+R)^N]/ [(1+R)^N-1]


P = Principal Loan amount

R = Monthly interest rate charged on the principal

N = Number of instalments to be paid each month

EMI is inversely proportional to the loan tenure. Therefore, the EMI will decrease when you pay the loan amount over a longer period of time, even though the interest amount will increase for the same.
