How Much Is a Law Firm Worth?
A law firm is typically worth 1.5x to 3.5x its seller's discretionary earnings (SDE), based on comparable transaction data from recent law firm business sales. For a business generating $1 million in annual revenue with the sector-average 25% net margin, that translates to an estimated value between $500K and $1.5M. The exact figure depends on profitability, growth trajectory, customer concentration, and how dependent the business is on its current owner.
Key Takeaway
A law firm is worth 1.5x to 3.5x SDE ($500K to $1.5M on $1M revenue). Profitability, growth, customer concentration, and owner dependency determine where your business falls in this range.
Conservative
$500K
0.5x revenue
Most Likely
$1M
1x revenue
Optimistic
$1.5M
1.5x revenue
Based on $1M annual revenue. Actual value varies by earnings and risk profile.
Law Firm Value by Revenue Size
The table below estimates what a law firm is worth at different revenue levels using industry-standard revenue multiples of 0.5x–1.5x. Revenue-based estimates provide a quick benchmark, but law firm valuation multiples based on SDE and EBITDA produce more accurate results because they account for profitability differences between individual businesses.
| Annual Revenue | Conservative | Most Likely | Optimistic |
|---|---|---|---|
| $250K | $125K | $250K | $375K |
| $500K | $250K | $500K | $750K |
| $1M | $500K | $1M | $1.5M |
| $2M | $1M | $2M | $3M |
| $5M | $2.5M | $5M | $7.5M |

Three Ways to Value a Law Firm
Professional business appraisers and experienced brokers use multiple methods to triangulate a fair market value. Each method answers a slightly different question about what a law firm is worth, and the most defensible valuations weight all three.
SDE Multiple Method
Best for owner-operated law firm businesses under $5M revenue
Seller's discretionary earnings represent the total financial benefit available to one full-time owner-operator. SDE adds back owner compensation, personal perks, depreciation, and interest to net income. This is the standard valuation basis for law firm businesses where the owner actively manages day-to-day operations.
EBITDA Multiple Method
Best for larger operations with hired management
Earnings before interest, taxes, depreciation, and amortization isolate operating profitability by removing capital structure and accounting decisions. EBITDA multiples are preferred for law firm businesses with revenue above $2M that employ a general manager, because the buyer will need to replace that role regardless of the valuation method chosen.
Revenue Multiple Method
Quick benchmark, does not account for profitability
Revenue multiples provide the simplest calculation (annual revenue times the industry multiple) but they are the least precise method because two law firm businesses with identical revenue can have vastly different profitability. Use revenue multiples as a sanity check against the SDE and EBITDA results, not as the primary valuation.
What Makes a Law Firm Worth More (or Less)
Where your law firm falls within the 1.5x–3.5x SDE range depends on five professional services-specific factors that buyers evaluate during due diligence. Strengthening these areas before listing can materially increase your sale price.
Client Retention Rate and Contract Terms
Annual client retention above 90% demonstrates sticky relationships and predictable revenue. Multi-year engagements or evergreen contracts increase value because they survive ownership transitions.
Billable Rate Structure and Utilization
Strong effective billing rates combined with team utilization above 75% indicate a firm that prices its expertise appropriately and manages capacity efficiently.
Partner and Owner Dependency
Firms where the founding partner personally manages all key client relationships face severe transition risk. Distributed client ownership across multiple professionals substantially increases the transferable value.
Referral Pipeline and Business Development
A documented referral network, inbound lead generation system, or strategic partnerships that produce new business independent of the owner's personal network reduce buyer risk.
Recurring Revenue from Retainer Agreements
Monthly or annual retainer contracts provide baseline revenue predictability that transforms a project-based firm into a subscription-like business model, commanding higher multiples.

Who Buys a Law Firm?
Competing law firms seeking practice area expansion or lateral attorney acquisition are the primary buyers. Insurance defense firms, personal injury mills, and immigration practices with systematized workflows attract PE interest through compliant management company structures. Associate attorneys executing internal succession buyouts, typically over 3-5 years, remain the most common transition path for solo and small firm practitioners.
Frequently Asked Questions
How do you calculate the value of a law firm?
The most reliable approach uses three methods in parallel. First, calculate seller's discretionary earnings (SDE) and multiply by 1.5x–3.5x. Second, calculate EBITDA and apply a 3.5x–7x multiple. Third, apply a 0.5x–1.5x revenue multiple as a cross-check. Weighting these three estimates produces a defensible valuation range. Valzura's free calculator runs all three methods simultaneously using law firm industry data.
What multiple is used to value a law firm?
The most common multiple for smaller, owner-operated law firm businesses is 2.5x SDE (seller's discretionary earnings), within a range of 1.5x–3.5x. Larger operations with hired management use EBITDA multiples of 3.5x–7x instead. Where a specific business falls within these ranges depends on profitability, growth trends, customer concentration, and owner dependency.
How many times revenue is a law firm worth?
A law firm typically sells for 0.5x to 1.5x annual revenue, with a median of 1x. Revenue multiples are the simplest valuation method but the least precise because they ignore profitability differences. A law firm earning 25% net margins is worth substantially more per dollar of revenue than one earning half that margin.
What is the average profit margin for a law firm?
The average net profit margin for a law firm is approximately 25%. Businesses operating above this benchmark command higher valuation multiples because each dollar of revenue contributes more to the bottom line. Margins below the industry average compress multiples, even when top-line revenue is strong. Profit margin is one of the most significant factors buyers evaluate because it directly affects the return on their acquisition investment and the speed of payback.
How long does it take to sell a law firm?
Most law firm businesses sell within 6 to 12 months from listing to close. Businesses with clean financials, documented processes, and earnings above $500,000 SDE tend to sell faster, sometimes in 3 to 6 months. The timeline extends if the business has undocumented owner perks, inconsistent earnings, or unresolved lease or license issues that require buyer due diligence.
