Profit & Loss FIFO Stock Trading

I am trying to figure out how to set up a spreadsheet that can match stock trades using FIFO when there are sells of partial lots and multiple securities listed on the spreadsheet. I do not want a running total for each symbol. I am looking to determine profit and loss per lot sold, so there will be partial lots being sold and added to all day long. By the end of the year, there could be 50 thousand trades on the spreadsheet with some sold the same day and others added and sold months later in various lots. Any help would be greatly appreciated.

I have posted to 2 other boards and received no reply form either:

Welcome to the forum!

Unfortunately our post does not comply with Rule 8 of our Forum RULES. Do not crosspost your question on multiple forums without including links here to the other threads on other forums.

Cross-posting is when you post the same question in other forums on the web. The last thing you want to do is waste people's time working on an issue you have already resolved elsewhere. We prefer that you not cross-post at all, but if you do (and it's unlikely to go unnoticed), you MUST provide a link (copy the url from the address bar in your browser) to the cross-post.

Expect cross-posted questions without a link to be closed and a message will be posted by the moderator explaining why. We are here to help so help us to help you!

Read this to understand why we ask you to do this, and then please edit your first post to include links to any and all cross-posts in any other forums (not just this site).

Thank you for adding links to your other posts.

Will you please attach a sample Excel workbook? We are not able to work with or manipulate a picture of one.

1. Make sure that your sample data are REPRESENTATIVE of your real data. The use of unrepresentative data is very frustrating and can lead to long delays in reaching a solution.

2. Make sure that your desired solution is also shown (mock up the results manually).

3. Make sure that all confidential data is removed or replaced with dummy data first (e.g. names, addresses, E-mails, etc.).

4. Try to avoid using merged cells as they cause lots of problems.

Unfortunately the attachment icon doesn't work at the moment, so to attach an Excel file you have to do the following: just before posting, scroll down to Go Advanced and then scroll down to Manage Attachments. Now follow the instructions at the top of that screen.

Please pay particular attention to point 2 (above): without an idea of your intended outcomes, it is often very difficult to offer appropriate advice.

I think it's a messy problem -- not hard, messy.

Here's a FIFO accounting for a single item (maybe gasoline):

	B	C	D	E	F	G	H	I	J	K	L	M
2				Sales
3				Date	1-Jan	7-Jan	16-Jan	26-Jan	2-Feb	7-Feb	11-Feb	20-Feb
5				Sell	3,912	3,424	7,032	17,128	10,483	9,180	284	4,062
6	Purchases			Avg Cost	$ 2.840	$ 2.840	$ 2.661	$ 2.603	$ 2.918	$ 2.773	$ 2.760	$ 2.661
7	Date	Unit Cost	Qty	DoNotUse
8	1-Jan	$ 2.84	8,900		3,912	3,424	1,564	0	0	0	0	0
9	10-Jan	$ 2.61	7,700		0	0	5,468	2,232	0	0	0	0
10	13-Jan	$ 2.36	8,800		0	0	0	8,800	0	0	0	0
11	20-Jan	$ 2.95	8,200		0	0	0	6,096	2,104	0	0	0
12	27-Jan	$ 2.91	9,200		0	0	0	0	8,379	821	0	0
13	6-Feb	$ 2.76	8,700		0	0	0	0	0	8,359	284	57
14	12-Feb	$ 2.66	9,300		0	0	0	0	0	0	0	4,005

The body of the table shows the amounts of each purchase lot used to make a given sale.

You have lots of different items. The same approach could be used, at the expense of some additional complexity in the formulas. But you'd run out of columns with the number of transactions you're talking about.

A VBA solution would be doable in the format you have, but you'd lose the auditability that the format above has.

There are surely stock-trading programs that do this ...
