An architecture firm is generally worth somewhere between two and just under four times its seller's discretionary earnings (SDE), with most firms landing near three. SDE is the owner's total benefit from the business: the profit plus the owner's salary, perks, and any one-time costs that would not carry over to a new owner. The firm's value is that number multiplied by a multiple, and everything that separates a firm worth two times from one worth nearly four comes down to two things: how much SDE the firm produces, and what multiple that SDE earns. This page walks through what an architecture firm is actually worth, why the common rules of thumb disagree, the two levers that move the number, and how to tell where yours stands right now, whether or not you ever sell.
How do you value an architecture firm?
There are three ways buyers and appraisers approach it. A market approach looks at what comparable firms have sold for. An income approach works from the present value of the firm's future cash flow. An asset approach values what the firm owns, and it is almost never the right lens here, because an architecture firm is asset-light: the value is in the people, the backlog, the client relationships, and the reputation, not the computers and the office.
You will also hear several quick rules of thumb: three to four times EBITDA, one and a half times book value, a percentage of net service revenue, or a figure per full-time employee. Treat them as rough gut checks, not answers. The revenue-based ones are especially unreliable in architecture, because of a distinction owners routinely blur. Gross revenue includes pass-throughs: sub-consultants you bring in, and reimbursable expenses like printing, travel, and permit fees. Net service revenue is only the fee for work your own people did, and the two can differ by a third or more. Feed a revenue rule the gross number and it flatters you badly.
That unreliability is a big reason we do not value on revenue at all. We work from SDE, which already nets those pass-throughs out (they are revenue and cost in equal measure, so they wash out of earnings) and reflects what the firm actually produces for its owner. From there, the two levers below decide where a specific firm lands.
What is an architecture firm worth by size and profile?
As a rough guide, in SDE terms: a small, owner-led practice tends to sit near two times. A typical established firm lands around three. A larger, departmentalized firm with more than one principal can reach the mid-to-high threes. These are approximate, and where a specific firm falls inside that spread depends far more on the two levers than on size alone.
It helps to picture the common shapes an architecture firm takes:
The solo licensed practitioner is one architect who does the work and holds the only stamp. It can be a good income for its owner, but because the firm cannot function without that one person, it sits at the bottom of the range and is often closer to an income stream than a sellable asset.
The boutique design studio, a principal plus a handful of staff, is usually busy and underpriced, with lumpy project revenue. It lands in the lower-middle until its pricing and backlog steady.
The regional multi-discipline firm, with several licensed staff and repeat institutional or municipal clients, is the most sellable shape and sits in the upper part of the range, provided its client relationships and rainmaking are not all concentrated in the founder.
The specialty technical firm, built on niche depth in an area like water, environmental, or structural work, commands the strongest fees and the highest end of the range, as long as that expertise is documented and does not live only in one person's head.
The production or volume firm competes on price and speed. Its margins are thin and it tends to sit low unless it moves up into a specialty.
We do not publish a fixed multiple for each shape, because at the top end the number is driven more by size than by anything a firm can control, and a tidy ladder would imply a precision that is not real. The range plus the two levers is the useful way to read it.

Because value starts from SDE, the most direct way to raise it is to raise the profit the firm earns on the work it already does. The number to watch is the net labor multiplier: net service revenue divided by the direct labor that produced it. Across the industry it tends to run around three. Strong firms reach three and a half or better. When it drops below roughly two and three-quarters, it almost always means the firm is underpricing its work or letting scope creep eat the fee it did negotiate.
It is the biggest lever most firms have, and it compounds. More fee per dollar of labor flows straight to profit and therefore to SDE, and it funds the better pay, tools, and systems that make the firm less dependent on you. Two firms doing identical work can be worth very different amounts, and the multiplier is usually where the gap starts. Because it is measured on net revenue, it also sidesteps the gross-versus-net confusion entirely, which is part of why it is a cleaner signal than any top-line number.
What sets the multiple: how much the firm depends on you
The same SDE earns a higher or lower multiple depending on how much of the firm walks out the door with you. This is the single biggest factor, and in architecture it has a sharper edge than in most businesses: the stamp. If you are the only licensed architect who can seal drawings, the firm legally cannot deliver work without you, and a buyer sees that immediately. A firm with more than one principal who can stamp, and clients who hire the firm rather than the founder, earns a meaningfully higher multiple than one that runs entirely through one person, even at the same SDE.
After dependence, the multiple responds to a few more things: a healthy backlog of signed, unstarted work; low client and sector concentration; any recurring or on-call work such as municipal agreements; and a defensible specialty. Each of these moves a firm up the range. The reverse pulls it down: a single stamp the firm cannot run without, lumpy fixed-fee work with little backlog visibility, one or two clients making up most of the revenue, margins that quietly fade on fixed-fee jobs, and an aging founder whose relationships have not been handed off.
What is your architecture firm worth right now?
The range above tells you the neighborhood. It does not tell you where in it your firm sits, and that gap is the whole question. Two firms with the same SDE can be a full turn apart depending on their multiplier, their stamp redundancy, their backlog, and how concentrated their clients are.
The free valuation calculator gives you a rough figure in about two minutes from your own numbers. The full assessment goes further: it measures your firm against the drivers that actually set the multiple and tells you where in the range you land and why. Worth knowing whether or not you ever plan to sell, because the same things that raise the number also make the firm easier to run.
How do you know if your firm is growing in value?
Watch a few numbers over time rather than a single snapshot. The net labor multiplier tells you whether your pricing and execution are improving. Utilization tells you whether the people you have are actually billable. Backlog, measured in months of signed work, tells you whether there is a revenue cliff ahead. And stamp redundancy, whether anyone other than you can seal work, tells you whether the firm is becoming genuinely transferable.
If revenue is climbing but the multiplier is flat and everything still routes through you, the firm is getting busier, not more valuable. The point is the direction those numbers move.
Where architecture firm values are heading
Private equity has become the dominant buyer in architecture and engineering, backing platforms that are steadily acquiring firms. This matters even if you never plan to sell, for two reasons: it sets the price of comparable firms, and it pulls experienced, licensed staff toward better-paying platforms.
What those buyers pay up for is worth noting, because it is the same list that makes a firm stronger to own: transferable client relationships, more than one licensed principal, a clean and visible backlog, and low client concentration. The firm that builds those things years ahead captures the premium. The one that waits until the founder is ready to leave, with relationships and the stamp still un-transferred, takes the discount, which is exactly when the firm is least valuable.
Start by seeing where you stand
You don't have to decide anything today, and the first step costs nothing. You can get a rough sense of what a firm like yours is worth in about two minutes with the free valuation calculator. If the number surprises you, or you want the full, specific version built on your own financials, that's what the assessment is for, and you can start there directly. For the broader picture of how value is figured, see our guide to small business valuation, or the closely related read on valuing a professional practice.
Knowing where you stand is the step almost every firm owner skips, because the profession tends to talk about value only at the moment of sale. It's also the step that tells you whether your work is building something, while there's still time to shape it.
