Law firm profit per partner: How to calculate it and what moves it

Profit per partner is a law firm's net income divided by its equity partners, and it is the figure partners compare most often. Numetix builds the monthly reports that feed it, reviewed by a named person. This guide covers the formula, its limits, and the levers that move it.

QUICK ANSWER: HOW DO YOU CALCULATE PROFIT PER PARTNER AT A LAW FIRM?

• Divide the firm's net income by the number of equity partners, using the same definition of net income every year so the trend is honest.

• Know the limits, because net income often includes pay for the partners' own work as well as profit earned as owners.

• Improve it through realization, utilization, leverage, and overhead, and track each lever monthly instead of waiting for the year-end number.

What is the standard formula?

The American Lawyer's Am Law 200 methodology defines profits per partner as net income divided by the number of equity partners. It also defines leverage as total lawyers, excluding equity partners, divided by the number of equity partners, and the profitability index as profits per partner divided by revenue per lawyer (How we calculated the Am Law 200). Smaller firms have no single standard, so write down your definition of net income and equity partner and keep it fixed. The profit per partner glossary entry gives a short definition.

What does a worked example look like?

Say a firm bills $3,000,000 and has $1,800,000 of expenses, including associate and staff pay. Net income is $1,200,000, a 40 percent margin. With four equity partners, profit per partner is $300,000. The figures are illustrative. If the firm adds a fifth equity partner and net income stays the same, profit per partner falls to $240,000, which is why partner admissions are a financial decision as well as a career one.

Why can the number mislead?

Law.com has pointed out that the net income used in these rankings is a mix of two things: the partners' pay for the work they do and their profit as owners (Your law firm's true profitability revealed). A firm can raise profit per partner by moving partners to nonequity status or by paying associates less, and neither makes the firm healthier. Read the figure next to the margin, revenue per lawyer, and the capital accounts. Our guide to partner capital accounts and distributions covers the equity side.

Which levers move it?

How do you track it during the year?

Do not wait for year end. Calculate a trailing twelve-month figure each month from the same reports the managing partner already reviews, listed in our guide to monthly financial reports for a managing partner. A trailing figure smooths the spikes that come from large settlements and shows whether a change is a trend.

Frequently asked questions

Is profit per partner the same as partner pay?

No. Profit per partner is an average of the net income pool. Actual pay depends on the partnership agreement, which may weigh seniority, origination, and performance. Treat the average as a firm measure, and use the agreement to see what each partner receives.

Does a small law firm need to track profit per partner?

Yes, if it has more than one owner, because it shows whether the firm supports its partners. Use a plain definition and keep it constant. Add a fair salary for each owner's work if you want to see how much profit is left after paying for that effort.

How often should the figure be calculated?

Monthly, on a trailing twelve-month basis, using the same method each time. A single month can swing widely when a large fee arrives or a big expense is paid. The trailing figure shows the direction, and the monthly detail shows what caused the change.
