Enter 3 out of 4 below

<-- Accum Value
<-- Principal
<-- Interest %
<-- Time
      

Given an initial balance of 120,
an interest rate of 5%,
and time of 7

Calculate the Accumulated Balance
using Simple Interest:

Accumulated Value formula

AV = Principal * (1 + (int. rate * time))

Plug in our values

AV = 120 * (1 + (0.05 * 7))

Simplify

AV = 120 * (1 + 0.35)

AV = 120 * 1.35

Calculate the total interest earned:

Total Interest Earned = Accumulated Value - Principal

Total Interest Earned = 162 - 120

Total Interest Earned = 42

Calculate the interest earned:

Interest per Period  =  Interest Earned
  t

Interest per Period  =  42
  7

Interest per period = 6

Final Answer



Accumulated Value using Simple Interest = 162
