Let's say I have a profit margin of 70% and expenses of $250 can I not calculate my estimated revenue?
I'm using this formula: Profit Margin = (Revenue - Expenses) / Revenue.
I'm trying to understand what my projected revenue would be given my profit margin and estimated cost.
I'm looking for an answer in the form of a formula for Revenue like R = ?.
This is probably elementary but any help is much appreciated. Thanks!
$$\text{Profit Margin} = (\text{Revenue} - \text{Expenses}) / \text{ Revenue}.$$
We'll use $P$ for profit margin; $R$ for revenue; and $E$ for expenses.
$$\begin{align} P = \frac{R-E}R &\iff RP = R-E \text{ (provided } R \neq 0)\\ \\ &\iff RP - R = -E \\ \\ &\iff R(P - 1) = -E\\ \\ &\iff R = \frac E{1-P}\;\text{ (provided } P-1 \neq 0) \end{align}$$
Now just "plug in" your values: $P = 0.7$, $E = 250$, to obtain revenue.
