I have a financial statement for a non-profit for four clinics, where you have to fill in the missing values. If you have a missing value for total revenue and have the value for total expenses and visa versa. How do you calculate the missing value? Do you obtain it from the assets/liability/equity information from the column above?

From past experience one can get at the
Approximate MARGIN RATE.
If you can obtain such a figure, this would enable you to get to the missing figures.
There is definitely a mathematical relationship
Between these figures.

Example :- 1/4
This becomes 1/5
How?

1 is the numerator
4 is the denominator.

You add the numerator to the denominator
Thus 1/4 becomes 1/5

Another example:-

Say 3/16
Becomes 3/19.

If it's four different clinics, why would they have the same margin?

kabaker, I think I might know the type of problem you're talking about, but we can't give specific answers without more detail from you. You're not really saying exactly what you're trying to do or what is available.

You can use the accounting equation to get missing totals. (e.g. total equity) You also may want to know that equity is made up only of revenues, expenses, investments and payouts. If corporation, investments are stock and payouts are dividends. If sole proprietorship, investments are investments and payouts are drawing.

That info might help. If not, please be more specific about what you have available.
