Calculating Net Position and Average Price

[carl]

my table looks like so:

Quantity Price

10 1.50
10 1.50
-5 1.25

Is there a way for me to calculate my net position (+15) and my average
price of my net position.

thank you in advance.

You can certainly sum the Quantity column to get the net position.

WRT "average price of my net position": I assume this is investment data. What
if the 2nd purchase was at 1.75 rather than 1.50. Did you sell 5 shares from
the 1st purchase or 5 from the 2nd? Do you want the average of 10 shares at
1.50 + 5 at 1.75, or 5 @ 1.50 + 10 @ 1.75? I think you'll need to identify the
shares by lot number and also include a column where you write BUY or SELL. If
you do that, you could set up a pivot table, using the lot numbers and the
transaction type for grouping.

Hi Carl
Your net position is the is the sum of the Quantity or =Sum(A2:A4)
The average price is calculated as an array formula (Shift-Ctrl-Enter) as
follows:

=SUM((A2:A4)*(B2:B4))

Net Position = sum(a1:A3)
Average price = sumproduct((a1:a3),(b1:b3))/sum(a1:a3)

If you are calculating average price for tax purposes, it's only buys
(positive quantities) which affect the average. So use the formulas
suggested only for positive quantities.

In the example you gave, your average cost is $1.50. Even though you sold 5
at $1.25, the cost of the remaining 15 shares is still $1.50 each.

And if the prices were different on the two purchases?

Then you take the average.
