7 Numbers Every Law Firm Owner Should Know
You don't need to become an accountant to run a financially strong law firm. But as the owner, there are a handful of numbers you should understand.
Not because you should spend your days inside spreadsheets. Quite the opposite. Knowing the right numbers helps you spend less time worrying about the business and make decisions faster when they matter.
7 Numbers Every Law Firm Owner Should Know
1. Operating Cash
What it tells you: How much cash the firm actually has available for operations.
For a law firm, it's important to distinguish operating cash from money held in client trust accounts. Your bank balance alone isn't enough, either. You need context around upcoming payroll, taxes, bills, debt payments and other obligations.
Question to ask: How much truly available cash do we have relative to what's coming due?
2. Revenue
What it tells you: How much revenue the firm is generating over time.
Don't look at one month in isolation. Compare revenue against prior months, prior years, budget and expectations. Also understand what is driving changes.
Question to ask: Is revenue growing because the underlying firm is getting stronger—or because of timing or a temporary spike?
3. Accounts Receivable
What it tells you: How much billed work remains uncollected.
An aging report is particularly useful because $50,000 outstanding for a few days is very different from $50,000 outstanding for several months.
Question to ask: How much do clients owe to the firm, and how quickly are we turning those invoices into cash?
4. Payroll as a Percentage of Revenue
People are often one of a law firm's largest costs. Looking at payroll in relation to revenue helps you understand how staffing costs are moving as the firm grows.
The useful range will vary based on practice area, staffing model, owner compensation structure and other factors, so don't blindly manage toward an internet benchmark.
Question to ask: Are staffing costs growing in a financially sustainable relationship to revenue?
5. Revenue Per Attorney
Revenue per attorney can provide another lens into productivity and capacity. Practice area, billing model, attorney experience, utilization, support staffing and collection performance can all affect this number. It's often most valuable when you compare your firm's number against itself over time.
Question to ask: As we add attorneys and staff, is our economic productivity improving, holding steady or declining?
6. Profitability
Revenue tells you how much the firm brings in. Profitability helps tell you what remains after expenses. Review both the dollars and the percentage of revenue represented by profit, and understand what's driving changes.
For some firms, deeper analysis by practice area or staffing structure can provide additional insight where the underlying data is reliable enough.
Question to ask: Is the business becoming more economically healthy as it grows?
7. Forward-Looking Cash
This is the number many owners are missing. Your historical reports tell you what happened. A cash-flow forecast helps answer: What happens next?
It considers expected collections and upcoming expenses so you can think ahead about payroll, taxes, hiring, owner distributions, marketing, equipment, office expansion, and other major investments.
Question to ask: What will our cash position look like over the coming months if things go according to plan—and what if they don't?
You don't need more numbers. You need better context.
One of the biggest mistakes is building a giant dashboard containing dozens of KPIs nobody actually uses. Start with the numbers tied to decisions. Then ask: What changed? Why did it change? Is it temporary? What should we do about it?
That's where financial reporting becomes financial management.
FAQ
What is the most important financial KPI for a law firm?
There isn't one number that adequately describes financial health. Cash, revenue, collections, staffing costs and profitability work together.
How often should law firm owners review financials?
Monthly financial reviews provide a useful regular rhythm for many firms, while certain operational measures such as cash and collections may need more frequent attention.
Should law firms use industry benchmarks?
Benchmarks can provide context, but your firm's practice areas, pricing, geography, staffing and business model matter. Your own historical trends are often an important comparison.
