Average Stock Formula

Given, below is the Stock Average Formula on how to calculate the average price if you have to purchase the same stock in n times.

  • Total shares bought = 1st share bought + 2nd share bought + 3rd share bought + …………. + nth share bought
  • Total amount bought = 1st share bought*1st purchased price + 2nd share bought*2nd purchased price + 3rd share bought*3rd purchased price + ………… + nth share bought*nth purchased price
  • Stock Average Price = Total Amount Bought / Total Shares Bought 

How to find Average Stock ?

  • Firstly, we will find the value of total shares and average cost from the given data.

Stock Average Examples

Example 1:

A man buys 3,6,8 and 4 shares of A,B,C and D companies which cost Rs 100, Rs 40, Rs 20 and Rs 80 per share respectively. Find the Average Cost of the share?


Given that,

Company A,B,C and D = 3,6,8,4 (shares)

Purchase Price:

Company A = Rs.100 per shares

Company B = Rs.40 per shares

Company C = Rs.20 per shares

Company D = Rs.80 per shares

Total shares = (A + B+ C + D) shares

Total shares = (3 + 6 + 8 + 4) shares

Total shares = 21

Total Amount of Shares = No.of shares*Purchase price(A) + No.of shares*Purchase price(B) + No.of shares*Purchase price(C) + No.of shares*Purchase price(D)

Total Amount of shares = 3*100 + 6*40 + 8*20 + 4*80

Total Amount of Shares = 300 + 240 + 160 + 320 

Total Amount of Shares = Rs.1020

Stock Average Price = Total Amount Bought / Total Shares Bought 

Put the value of Total Amount of shares i.e Rs.1020 and Total Shares Bought i.e 21 in the above formula.

Stock Average price = 1020 / 21

Stock Average price = Rs.48.5714
