Explanation

In simple interest calculations, the principal is the original amount of money that is borrowed or invested. It is the starting point for the calculation of interest, and is denoted as "P" in the formula for calculating simple interest.

Simple Interest = (P x R x T) / 100

where P is the principal, R is the interest rate, and T is the time period (usually given in years).
