At simple interest, the interest is computed on the original principal during the whole time, or term of the loan, at the stated annual rate of interest.

Simple interest is calculated by means of the formula: I=Prt

Where
P = the principal, or the present value of S, or the discounted value of S, or the proceeds.
I = simple interest.
S = the amount or the accumulated value of P, or the future value of P, or the maturity value of P.
r = annual rate of simple interest.
t = time in years.
