How to Use This Profit Margin Calculator

Enter your total revenue — the gross income your law firm business earned over a given period. This is the top line before any costs are subtracted. Use monthly figures for the most actionable insights, or annual figures for a big-picture view.

Enter your cost of goods sold (COGS) — the direct costs tied to delivering your product or service. For law firm businesses, this typically includes Attorney compensation & draws and Paralegal & staff salaries. The calculator subtracts this from revenue to show your gross profit and gross margin.

Profit Margin Calculator for Law Firm Businesses

Understanding profit margins is critical for any law firm business. With gross margins typically ranging from 40-60% and net margins between 15-35%, knowing where you stand relative to industry benchmarks helps you make informed decisions about pricing, hiring, and growth investments.

The main cost drivers in a law firm business are Attorney compensation & draws, Paralegal & staff salaries, Malpractice insurance, Legal research subscriptions (Westlaw, LexisNexis), Office rent & overhead, Bar dues, CLE & licensing. Each of these categories affects your margin differently, and small improvements in the largest categories can have an outsized impact on your bottom line. Regularly reviewing your P&L statement alongside this calculator helps you spot trends before they become problems.
