Law Firm Overhead Calculator & Break-Even Analysis
Calculate your law firm's monthly overhead, overhead rate per attorney, and break-even billing requirements. Benchmark against industry averages by firm size.
Calculate Your Firm's Overhead
Enter your monthly expenses across all major categories to see your total overhead and break-even requirements. The calculator organizes costs into fixed expenses (rent, insurance, software subscriptions, loan payments) and variable expenses (staffing, marketing, court costs, continuing education). Required inputs include monthly rent or mortgage, staff salaries and benefits, malpractice insurance premiums, technology and software costs, marketing and advertising spend, bar dues and CLE costs, office supplies and equipment, and miscellaneous expenses. The calculator outputs total monthly overhead, overhead as a percentage of revenue, per-attorney overhead rate, the number of billable hours required to break even at your billing rate, and a comparison against industry benchmarks by firm size category.

How to Use This Calculator
Enter Fixed Costs
Input monthly amounts for rent or mortgage, malpractice insurance, health insurance, technology subscriptions (practice management, research, accounting), loan payments, and any other costs that remain constant regardless of caseload. These form the baseline you must cover every month.
Enter Variable Costs
Input monthly averages for staff compensation (paralegals, legal assistants, reception, bookkeeping), marketing and advertising, court costs and filing fees, CLE and bar dues, travel, and office supplies. These fluctuate but should be averaged over the prior 12 months for accuracy.
Set Revenue Parameters
Enter the number of billing attorneys, the average hourly rate, and your current monthly gross revenue. The calculator uses these to compute your overhead rate and compare your break-even requirements against your actual billing capacity.

Frequently Asked Questions
What is a good overhead rate for a law firm?
Industry benchmarks suggest that a well-managed law firm should target an overhead rate of 35-45% of gross revenue. Solo practitioners can often achieve 30-40% by keeping staffing lean and using technology to replace manual processes. Small firms with 2-10 attorneys typically run 40-55% due to staffing costs. Firms above 55% overhead should evaluate whether staffing levels, office space, or technology costs can be optimized. The most profitable firms consistently keep overhead below 40% while maintaining service quality through automation and efficient processes.
What are the biggest overhead expenses for law firms?
For most law firms, the three largest overhead categories are: (1) Staff compensation, which typically accounts for 35-45% of total overhead including paralegals, legal assistants, office managers, and bookkeepers; (2) Office space, accounting for 15-25% of overhead including rent, utilities, insurance, and maintenance; and (3) Technology, accounting for 8-15% of overhead including practice management software, legal research subscriptions, phone systems, and IT support. Marketing, malpractice insurance, and CLE costs make up most of the remainder.
How can I reduce my law firm's overhead?
The highest-impact strategies include: automating client intake and document generation to reduce staff hours (potential 20-30% staff time savings), moving to a virtual or hybrid office model to reduce rent (potential 50-70% space cost reduction), consolidating technology platforms to eliminate redundant subscriptions (potential 15-25% tech cost savings), outsourcing bookkeeping and IT support rather than hiring full-time staff, and implementing flat-fee billing for predictable matters to reduce time tracking overhead. Most firms find that technology investment pays for itself within 3-6 months through staff time savings alone.
