Law firm KPIs every managing partner should track.
Updated September 28, 2026 · Meridian Command
The metrics that matter most to a law firm’s managing partner fall into three groups: money (net margin, collection rate, A/R aging), people (utilization, realization, turnover), and growth (lead-to-client conversion, cost per new client). Track them monthly, side by side, so a problem in one shows up before it hits the others.
The glossary
| Metric | Formula | Why it matters |
|---|---|---|
| Utilization rate | Hours recorded ÷ hours available | How much of a timekeeper’s available time is recorded as work. Subtract approved time off from available hours so vacations don’t read as underperformance. |
| Realization rate | Hours billed ÷ hours worked | How much recorded work actually reaches an invoice. Low realization points to write-downs, discounting, or unbilled work. |
| Collection rate | Amount collected ÷ amount billed | How much of what you invoice turns into cash. The gap between the two is revenue the firm earned but hasn’t received. |
| A/R aging | Open invoices grouped by days outstanding | Balances in the 90-day-plus bucket are the hardest to collect. Watch how that bucket moves month to month. |
| Net margin | (Revenue − expenses) ÷ revenue | What the firm keeps. A growing firm can see revenue rise while net margin falls. |
| Revenue per lawyer | Revenue ÷ number of lawyers | A simple productivity measure for comparing periods, offices, or practice groups. |
| Lead-to-client conversion | New clients ÷ leads | How well intake turns inquiries into hired clients. Track each stage: qualified, consult scheduled, consult completed, hired. |
| Cost per new client | Marketing spend ÷ new clients | What each hired client costs to acquire. Compare it by source to see which spend pays off. |
| Payroll as a share of expenses | Payroll cost ÷ total expenses | Payroll is usually a firm’s largest cost. Track how the share changes over several months. |
| Staff turnover | Departures ÷ average headcount | Rising turnover often follows workload imbalance. Pair it with utilization by person. |
| Trust account variance | Difference between bank, journal, and client ledger totals | Should be zero. Any variance needs to be explained and resolved. |
Leading and lagging indicators
Revenue and profit are lagging indicators. By the time they move, the cause is usually months old. Leads, consults, conversion, and utilization are leading indicators. In the Meridian Command demo, monthly leads fell from 262 to 99 in a single month, before the drop showed up in revenue.
How often to review them
Monthly for the full set, weekly for intake and utilization if the firm is growing fast. Quarterly financial statements are too late to act on most of these signals.
