Explanation: 

Detailed explanation-1: -Compound interest is calculated by multiplying the initial loan amount, or principal, by the one plus the annual interest rate raised to the number of compound periods minus one. This will leave you with the total sum of the loan including compound interest.

Detailed explanation-2: -To calculate your monthly car loan payment by hand, divide the total loan and interest amount by the loan term (the number of months you have to repay the loan). For example, the total interest on a $30, 000, 60-month loan at 4% would be $3, 150.

Detailed explanation-3: -Calculating EMI has a Simple Formula, Which is As Follows: EMI = (P X R/12) X [(1+R/12) ^N] / [(1+R/12) ^N-1]. Here, P is the original loan amount or principal, R is the rate of interest that is applicable per annum and N is the number of monthly installments/ loan tenure.

Detailed explanation-4: -You can calculate your total interest by using this formula: Principal loan amount x interest rate x loan term = interest.
