# Formula for summing purchases and sales

H

#### Helixal

a b c d `f g h i

1 date nane1 buy 34 99

2 date name1 sell 24 56

3 date name2 buy 56 99

4 date name3 buy 36 103

5 date name 3 buy 28 34

6 date name3 sell 12 470

I want to create an excell spread sheet of 8 columns and unlimited rows.
I'd like column h to be the sum of the numbers in column f for each name.
where buy would be a positive number and sell would be a negative number.
In this example the number 10 (34-24) would go in cloumn f row 2. These are
the sum of buys and sells for name1. Name2 would be 56 in row 3 and name3
would be 76 in row 6. Any row could contain words other that "buy" or "sell"
in which case that entire row should be ignored. If that happens to be the
last row of any given name then the result should be placed on that row.

Similarly i'd like to sum column g and place the result in column i. In
this case however the word buy has negative meaning and the word sell has a
positive meaning. So row 2 i would contain -43. 3i would contain -99 and
6i would contain 333.

Think of these as purchases and sales of securities. Name1 could stand for
the purchase of 34 shares of AT&T for \$99 and the sale of 24 shares at \$56.
The result would be 10 shares and \$-43 (LOSS)

The trick is to sum the numbers till the name changes. There are no row
delimiters between names.

Help would be appreciated.

A combination of SUMPRODUCT array formulas and Excel's Data/Subtotals
command might be able to do what you want.

Could you give me an example of how this would be done for one of the target
columns?

The example you gave is not quite clear to me, nor is what exactly you
require. The names of the columns you give (A:I) do not correspond to
your description of "8 columns". It is also not clear what "result" you
want in the subtotal rows.

purposes, necessary for some analytical tools. Second, I entered
as +34 units for an amount of -99, the second is -24 units and an amount
of +56); it may be possible to use the text value of "buy"/"sell" in the
formulae to effect the required sign, but that would unnecessarily
complicate the case for a brief answer.

Then, try this: cell G3: =E3+SUMIF(\$C\$2:C2,C3,\$E\$2:E2) and
H3: =F3+SUMIF(\$C\$2:C2,C3,\$F\$2:F2); drag those down for the remaining
rows. G2 and H2 are simply =E2 and =F2, respectively.

The Excel menu command "Subtotals" can be used to insert total lines at
the change of the value in certain columns (needs headers). However, I
can't think of any kind of total suitable for such a line.

You mention "unlimited rows", but Excel spreadsheets are limited in how
many rows they can carry. For much more flexibility in the size of the
dataset and for your reporting requirements, Excel may well be not quite
the right tool and you might want to consider a database program like

Michael,

The two formulas appear to work beautifully.
In the modified spreadsheet attached , the formulas become:

G2=E2+SUMIF(\$C\$1:C1,C2,\$E\$1:E1)
H2=F2+SUMIF(\$C\$1:C1,C2,\$F\$1:F1)
in the attached file TEST1.xls.

In the modified spreadsheet I manually inserted the minuses.

Could you suggest a formula for inserting a "-" in column F for a buy and
"-" in coulum G for a sell. The real spreadsheet is currently 650 rows in
length and this would be helpful. In my original posting I mentioned that
the maximum number of rows.

Many thanks,
Helixal

I have been so far unsuccessful in posting the spreadsheet TEST1.xls. It's
only 16 KB in size. I will try to start a new thread and see if that works.
Any suggestions would be appreciated.

The usual way to do this is to create a "helper column" with the
appropriate formula, then Copy/Paste Special (Values) the results back
into the original column and delete the "helper column". The formula
might be: =IF(D2="sell",-E2,E2); drag down.

I'm wondering if a procedure (Macro?) could do this. To complicate matters,
as buy) and remove(same as sell) and possibly something(s) else requiring no
treatemnt. After running this procedure to add the +'s and -'s, the macro
could then perform the summation to create the additional columns G and H
discussed earlier..
