Law Firm Business Plan Template

Move to the Revenue Forecast sheet and set your billable hours assumptions. A realistic first-year attorney utilization rate is 60–70% of available hours (accounting for 20–30% time spent on business development, admin, and pro bono work). By year two, mature practices reach 70–85% utilization. Set your billing rates by practice area—family law and immigration might be $200–$300/hour, corporate work $300–$500/hour, and litigation $250–$400/hour depending on your experience and market. Model your client acquisition timeline: months one and two are often 20–30% utilization as you build the client base; months three through six ramp to 50–70%; months seven through twelve approach your target utilization. This forces you to model the cash crunch months explicitly.

The second key metric is attorney utilization—what percentage of available working hours are billable to clients. A solo practice operating 40 hours per week, 50 weeks per year has 2,000 available hours. If you bill 1,200 of those hours to clients, that's 60% utilization—reasonable for a solo practice managing business development. If you bill 1,600 hours, that's 80% utilization—high for someone managing a practice alone. Most law firms target 65–75% utilization for partners (accounting for practice management and business development work) and 75–85% for associates who primarily bill time. Excessive utilization targets (90%+) lead to burnout and underinvest in business development, which eventually hurts revenue growth.
