Most established small law firms are worth roughly 2.6 to 4.7 times their seller's discretionary earnings (SDE), with a typical firm landing near 3.6 times. SDE is the owner's total benefit from the practice: net profit plus the owner's own compensation, benefits, and one-time costs a new owner would not carry. But no industry we cover has a wider gap between the range and any individual answer, because law firm value turns almost entirely on one question: do clients hire the firm, or do they hire you? A firm with transferable client relationships, second-chair attorneys, and a documented intake engine earns the range above. A practice that is one lawyer's reputation wearing a firm's name can fall below the bottom of it entirely, and often does.

If you have already searched this topic and come away with numbers that flatly contradict each other, you are not confused. The published guidance really does disagree, and it is worth understanding why before you apply any of it to your firm.

Why the numbers you have read do not agree

One widely quoted rule of thumb says a law firm is worth 0.5 to 3.0 times gross revenue, a range so wide it values the same $1 million firm anywhere from $500,000 to $3 million. Guides written on an earnings basis quote 2.5 to 4 times SDE. Succession consultants who see actual practice sales report most closing around 0.6 to 1.0 times revenue. And at least one veteran appraiser argues, with some justice, that every standard method fails for law firms because the sale data to calibrate them barely exists.

Three things reconcile most of this.

Revenue multiples and SDE multiples are the same fact in different clothes. A firm collecting $800,000 with $320,000 of SDE that sells for 0.8 times revenue sold for $640,000, which is exactly 2.0 times SDE. Same deal, two multiples. The revenue rule feels smaller only because the base is bigger. Convert everything to one basis, SDE, and the published ranges stop fighting; what remains is real variation in the firms themselves.

The market really is thin, and there is a legal reason for it. Law firm sales are confidential, and professional conduct rules restrict who can buy one: in nearly every state, only another lawyer or law firm can own a law practice. That shrinks the buyer pool to a fraction of what an equivalent accounting practice enjoys, which suppresses the number of transactions, which is why nobody can hand you a thick book of comps. A thin market does not make your firm worthless. It makes preparation and transferability worth more, because the buyer who does appear has options.

The low observed numbers describe which firms sell, not what a well-built firm is worth. Most practices that actually come to market are solo practices where the goodwill is overwhelmingly personal. Those trade low, often 1 to 2 times SDE, and frequently on earnout structures where the seller is paid as a share of what the clients actually generate for the successor. The upper part of the range belongs to firms that solved the transferability problem before going to market. The distance between those two outcomes is the most actionable fact in this entire subject.

What counts as earnings: SDE for a law firm

SDE is net profit plus everything the owner personally takes from the practice: salary, benefits, personal expenses run through the firm, plus interest, depreciation, and true one-time costs. A firm showing $150,000 of net profit that pays its owner $180,000 in salary, carries $20,000 of owner benefits, and absorbed a $10,000 one-time office move has an SDE of $360,000. That, not the tax return's bottom line, is the number a multiple gets applied to.

One adjustment matters more for lawyers than most owners: revenue means collected fees, not billed and certainly not billable. A buyer values what hits the bank. If your books show strong production but your realization and collection rates leak, the valuation starts from the leaked number, which is one of several reasons those operating metrics deserve attention long before any sale conversation.

Clients hire the lawyer, or they hire the firm

Every industry has its version of owner dependence. In law it has a name lawyers already use: personal goodwill versus practice goodwill. Personal goodwill is value tied to you, your reputation, your relationships, your rainmaking. It leaves when you do, and no buyer can be certain it transfers. Practice goodwill belongs to the firm: a brand that is not your surname, associates who carry client relationships, a referral and intake engine that produces matters without your personal network, a form bank and documented processes that make the work repeatable.

The uncomfortable arithmetic is that most small firms are built almost entirely on personal goodwill, and the multiple says so. The test is blunt: if you stopped practicing on a Friday, how many of your clients would still call the office on Monday? If the answer is "most of them, because they have relationships with other attorneys here and the firm's name is on the work," you own a business. If the answer is "few, because they hire me," you own a practice, which is a fine thing to own and a hard thing to sell.

Converting one into the other is slow, deliberate work: putting a second attorney into every significant client relationship, moving intake off the owner's phone, building the form and brief bank, and, for owners thinking in decades, migrating the brand away from a personal surname. None of it is exotic. All of it moves the multiple, and every step also makes the firm less exhausting to run now.

Practice area is destiny

A family law practice, an estate planning practice, and a personal injury practice with identical earnings are not worth the same, because the earnings do not behave the same.

Recurring and repeat-fee work prices highest. Estate planning with ongoing plan reviews and trust administration, corporate work on standing retainers, any practice where this year's clients are structurally next year's clients. This is the law-firm version of recurring revenue, and it earns the top of the range.

Volume practices with process-driven intake price well when the machine, not the owner, produces the matters: immigration, uncontested family matters at flat fees, high-volume estate work with documented systems.

Contingency practices are real but volatile. A personal injury firm can produce outstanding earnings, but they arrive in lumps tied to settlement timing, and the open case inventory is genuinely difficult to price. Buyers discount volatility even when they respect the earning power.

Purely personal litigation prices lowest, however skilled the litigator, because the thing being sold, the lawyer's courtroom reputation, is precisely the thing that cannot transfer.

The scoreboard that sets your income and your multiple

The operating metrics a buyer would examine in diligence are the same ones that decide what you take home this year, which is why they are worth watching whether or not you ever sell. Publicly available industry benchmarking shows the average small firm captures only about a third of its theoretical attorney capacity as collected revenue, the compounded result of three leaks: utilization (the share of working hours that are billable at all), realization (the share of billable time that actually reaches an invoice, industry average around 88 percent, with most firms quietly writing down hours they feel they should not bill), and collection (the share of invoiced dollars that arrive, around 91 to 93 percent on average). Add lockup, the days between doing the work and banking the fee, where industry medians run around three months.

Each of those has a boring, known fix: tighter engagement letters and scope conversations for realization, cards on file and automated billing for collection, and rates that have actually been revisited in the last two years, because most small-firm rates were set years ago and never moved. A firm that runs this scoreboard well shows up to any valuation with higher earnings and better proof that the earnings are durable. That is the same improvement counted twice, which is the entire case for starting now.

What increases the value of a law firm?

Reduce the share of client relationships that live only with you. Grow the recurring and repeat-fee side of the practice deliberately. Keep client concentration in check, since a single client above 10 to 15 percent of revenue draws a discount in any professional services firm. Fix the realization and collection leaks, which raises current income and the multiple's base at once. Document what makes the work repeatable. And if an eventual transition matters to you, start years early: the buyer pool is thin, internal successors need runway, and the goodwill conversion is measured in years, not quarters.

What is your law firm worth right now?

You can get most of the way with an afternoon and your own numbers. Compute your SDE from collected revenue. Apply the range above with your size in mind. Then be candid about the placement questions: how much of the client base would survive your departure, how much of your revenue recurs, how concentrated it is, and what your realization and collection actually run.

The step most owners cannot do alone is the comparison: what do the cost lines, margins, and productivity of a firm like yours normally look like, and which gap between your numbers and those is costing the most value? That is what the assessment measures. It takes your actual financials, benchmarks them against businesses like yours, and returns your valuation with the drivers ranked by dollar impact, so the number comes with its own to-do list.

How do you know if it is growing in value?

A firm's value moves slowly and silently. A year of rate stagnation, realization drifting three points, one associate departure that puts key clients back on your desk: none of it appears on a monthly P&L as a line called "value," and all of it moves the number. Owners who re-measure annually catch the drift early. Owners who improve one driver a quarter, rates this quarter, a second attorney into three key relationships the next, compound the multiple the same way the practice compounds referrals. The moves that raise the number are the same moves that make the firm more profitable and less consuming to run now.

Common questions

How much is a law firm worth?
Most established small law firms are worth roughly 2.6 to 4.7 times seller's discretionary earnings, with a typical firm near 3.6 times. The largest single variable is transferability: a firm whose client relationships, intake, and work product belong to the firm earns the range, while a practice built entirely on one lawyer's personal goodwill can trade below it, often at 1 to 2 times SDE and frequently on an earnout tied to client retention.
What is the law firm valuation rule of thumb?
The commonly quoted rule of thumb is 0.5 to 3.0 times gross revenue, a range too wide to be useful. Reports from consultants who see actual practice sales put most transactions around 0.6 to 1.0 times collected revenue, which at typical small-firm margins works out to roughly 1.5 to 2.5 times SDE. Rules of thumb ignore practice area, recurring revenue, and transferability, which is exactly where the real variation lives.
What multiple do law firms sell for?
In SDE terms, commonly around 2.6 to 3.6 times for established firms with some transferable goodwill, reaching 4 times and above for larger firms with recurring fee structures and client relationships held at the firm level. Personal-goodwill solo practices transact lower, and often with contingent structures rather than a fixed price, because the buyer cannot be certain the clients transfer.
How do you value a solo law practice?
Start with SDE, then be unsentimental about transferability. If clients hire you personally, a buyer is purchasing an introduction, not an income stream, and solo practices commonly sell at the low end of the market, on earnouts, or as a percentage of revenue actually collected from transferred clients over two to three years. The counterweight is anything that makes the practice run without you: documented intake, flat-fee productized services, repeat-fee clients, and a staff that carries the work.
Is a personal injury firm valued differently?
Yes, in two ways. Contingency earnings are lumpy, so buyers average across years rather than pricing a single strong one. And the open case inventory is an asset that is genuinely hard to price, since its value depends on outcomes and timing that nobody controls. A PI firm with a documented case-acquisition engine and steady multi-year averages is valuable; the volatility is priced, not ignored.
Can I get a free law firm valuation?
Free valuations exist, and most come from parties with an interest in the answer, typically brokers who want the listing. A free calculator can give you a defensible starting range from your earnings. What it cannot do is tell you where your firm sits within the range, which depends on transferability, concentration, and your operating metrics. That placement, with the drivers ranked by dollar impact, is what a paid owner-side assessment is for.
Do I need a "business valuation law firm" to value my firm?
Probably not, and the phrase usually points somewhere else: law firms that handle valuation disputes in litigation, divorce, or shareholder matters. If you are in one of those, you need a credentialed appraiser whose report can withstand challenge, and your counsel will engage one. If you are an owner who wants to know what the firm is worth and what drives it, you need your SDE, your operating metrics, and a defensible range, which does not require litigation-grade appraisal fees.
Why is it so hard to find law firm sale comps?
Because sales are confidential and the buyer pool is legally restricted: professional conduct rules in nearly every state mean only lawyers or law firms can own a law practice. Fewer eligible buyers means fewer transactions, and fewer transactions means no meaningful public database of prices. It is the structural reason law firm valuation leans on earnings analysis rather than comparable sales, and a good reason to begin succession conversations years before you need them.

Multiple ranges reflect Honest Assessment's valuation model for owner-operated firms, expressed on an SDE basis. They are size-spanned ranges, not observed sale prices, and where a specific firm lands depends on the factors above.
