Not a sophisticated answer either, but there are two (additional) ways of looking at the cash reserve:
a. Monthly cost versus months of subsistence based on available cash.
b. Hours required to finish all the projects currently engaged, versus available cash reserve to do so.
Whereas b requires more calculations, they both provide realistic survival scenarios, which are the basis for the best recommendation: build a year of cash reserves, no matter what the size of the firm, cutting back on profit sharing until accomplished.
Like Mr. Glisson, we invoice very similar amounts with similar costs. Having a reasonable cash reserve has really made a difference in fronting economic contractions where our industry is the first to slow down and one of the last to recover.

Well, not as sophisticated as the other answers, I will offer the following which, not totally surprising, lines up with one of the answers below:
We are a small firm of 9 people, we bill about 1.2 million a year, usually 100-140K per month. Our expenses average about 80-90K per month. We try to keep anywhere from 140-200K in our account. Through experience, we have learned to become concerned when our account reaches 140K. If it drops to 100K, we usually act by making plans etc. Obviously, we also take into account our receivables and how likely we are to get them in a timely manner.
On the plus side, if we get to 200K in the account, we usually pay out bonuses! Hopefully this helps by applying numbers to some of the general rules listed below.
