Display cumulative average value of a column in worksheet based on data entered by manager

Summary:

Manager enters a bonus percentage for his/her reportees in the compensation worksheet. Say, manager has 10 reportees and for each of them manager enters 5 as bonus % in the bonus% column. So, the calculation is as below

Summation of bonus % given to all reportees = 5 +5……5 = 50

Average value = Summation / total number of reportees = 50/10 = 5

Can this value be calculated and displayed in the worksheet after when manager has entered bonus % value and saved the worksheet?
