Simple Interest Calculator

This Simple Interest Calculator calculates an accrued total amount that includes Principal plus Interest.

Formula:

Simple Interest Equation (Principal + Interest) A = P ( 1 + rt )

Where:

A = Total Accrued Amount (Principal + Interest)
P = Principal Amount
I = Interest Amount
r = Rate of Interest per year in decimal; r = R / 100
R = Rate of Interest per year as a percent; R = r * 100
t = Time Period involved in years

From the Base formula, A = P ( 1 + rt ) derived from A = P + I and I = Prt
So, A = P + I = P + Prt = P ( 1 + rt )
