apple numbers formula referencing its own cell

I need to create a formula that allows a calculation to reference its own cell, but I keep getting this message:


This formula can’t reference its own cell, or depend on another formula that references this cell.


I need to make this happen because in my example I have a total investment amount for a person. this converts to a percentage base on what the total of all the peoples investments are. when a new project finishes and there is a profit, I use their percentage to calculate their share of the profit. After this, their share of the profit adds to their total investment amount, more or less a running total. Is there anyway to do this?

You could consider a "capital schedule" something like the following:



The input values are in blue.


Formulas:


C2, filled down:

=B2/SUM(B)


D2, filled down:


=D$5*C2


E2, filled down:


=B2+D2


A5, filled right to C5:


=SUM(B)


E5: =SUM(E)

Something like this?



Total table:


C2, filled down:


=B2/SUM(B)


G2, filled down:


=B2+SUM(D2:F2)


H2, filled down:


=G2/SUM(G)


Project tables:


C2, filled down:


=B2/SUM(B)


D2, filled down:


=D$5*C2


Blue figures are manual inputs.


In general, schedules like this tend too work from a Beginning Balance to an Ending Balance.


The Ending Balance then becomes the next period's Beginning Balance and the Ending Percent shares are then applied to the next period.


Some sort of iterative calculation typically should not be necessary unless the operating agreement calls for some sort of "rebalancing" to keep percent shares constant over time. That, I think, would be rare. Does yours?

Yes that I have already, but on the sheet for the individual investor I run a tally for the profits on each job. I total them at the bottom and add that to the original investment. This new number is whats used to get their percentage of overall investment funds which creates their profit percentage. I need to find away to use the profit totals, add them to the original amount and send them to the original sheet without this error.

Hi Mike,


You might consider manual manCopy and Paste to grab the profit total(s) and paste them to a place where they may be 'added to the original investment. Ridding the document of the self reference error mens you need to break the circle at some point.


A look at your calculation process might provide a more detailed solution.

Thank you, my sheet is very similar to this. The issue is (using your sheet as an example) the new total E5 $1400 needs to become the amount that calculates the overall percentage of the investment pool. Because there are 3 different groups of investors used depending on the project, each individuals overall percentage of the total funds could change depending on which pool is used for which investment. So if on the new investment pool A of investors is only used and they gain a profit from this investment, their new total investment amount (original investment plus new profit) becomes a larger percentage of the overall sum of investor money.


I need to attach the sheet as it has layers and it wont work to show it as a Jpeg. Is there a way to upload it?

Theres a link. As of now I have the percentages on the first sheet based of initial investment, but it needs to be off of current investment. The amounts change as different groups of investors are used on different projects. That creates the issue of calculating based on its own cell data as the percentage is what drives each investors amount. Any ideas or help is greatly appreciated.

I had a quick look and suggest spending some time with the templates at File > New in your menu to see good examples of organizing documents in Numbers. Unlike in Excel, you can easily have multiple tables on a sheet. Using Footer Rows can make your life much easier. Also have a look at Help > Numbers Help.


Once you've got the basics down and reorganized the document I think you will find it much easier to craft an efficient solution.
