Most established private businesses are valued on a multiple of normalized EBITDA: a buyer rebuilds your earnings to show what the business really produces, applies a multiple typical for your industry, and adjusts within that range according to how durable and how transferable those earnings are. Ask three buyers and you will get three ranges rather than three numbers, but they will agree on that method. This guide walks through it end to end, so you can see your own range coming and understand what would move it.
None of it is proprietary. The mechanics of a private-company valuation are well understood by the people who do this for a living, and an owner who understands them walks into any conversation on much steadier footing.
Key takeaways
- Buyers value normalized EBITDA, not revenue and not the profit on your tax return.
- Rebuilding earnings often moves the valuation more than the choice of multiple does.
- Your industry sets the starting range; risk and transferability decide where inside it you land.
- The result is a range with a midpoint, because deal structure and diligence findings cannot be known in advance.
- The levers that raise it — customer diversification, management depth, clean financials — take twelve to thirty-six months to show up in numbers a buyer will credit.
What are buyers actually paying for?
Start with the thing a buyer is buying. It is not your revenue, and it is not your assets in most cases. It is the future cash earnings the business can produce for its new owner, and the confidence that those earnings will survive the change of hands.
That single idea explains most of what follows. Revenue tells a buyer how much activity the business generates, but not whether that activity is profitable or durable. A company doing 20 million dollars in sales at thin, volatile margins is worth less than one doing 8 million at healthy, stable margins. Assets matter mostly as a floor and as a source of risk, such as whether equipment is modern or facing a wave of replacement. What a buyer underwrites is the earnings stream and the likelihood it continues.
This is why two businesses with identical revenue, or even identical profit on paper, can be worth very different amounts. The gap is almost always about risk and transferability: how predictable the earnings are, how concentrated the customer base is, and whether the business can run without the current owner in the building.
It also explains a common misconception. Owners often hear that businesses in their industry sell for "one times revenue" or some similar rule of thumb, and they anchor on it. Experienced buyers rarely price an established company off revenue directly, because two businesses with the same top line can have very different earnings and very different durability. The revenue figure is a starting point for a conversation, not a basis for a price. What gets underwritten is the earnings, and the quality of those earnings, every time.
Why do buyers start with EBITDA?
For most established businesses, the earnings figure buyers anchor on is EBITDA: earnings before interest, taxes, depreciation, and amortization. It sounds like accounting jargon, but the reason buyers favor it is practical. EBITDA strips out the things that are specific to the current owner and will not carry over, namely how the business is financed and how its taxes are structured, and leaves an approximation of the cash the operation itself throws off.
A buyer will bring their own financing and their own tax situation. What they need to know is what the business earns before those choices are layered on. That is the number they can compare across companies and the number they will apply a multiple to.
There is an important catch, though. The EBITDA on your tax return is rarely the EBITDA a buyer uses.
Buyers normalize your earnings first
Before applying any multiple, a buyer rebuilds your earnings into what is usually called normalized or adjusted EBITDA. They add back costs that a new owner would not carry and subtract benefits that would not continue, so the number reflects the business as it would run under new ownership rather than as it was optimized for the current owner's taxes and lifestyle.
The adjustments that show up in nearly every deal are:
- Owner compensation. Pay above what it would cost to hire a market-rate manager gets added back. Pay below market gets subtracted. The business is priced as if a professional manager were running it.
- One-time items. A legal settlement, a one-off equipment sale, a pandemic-era relief payment. These are backed out in both directions because they will not recur.
- Related-party and discretionary costs. Below-market rent paid to an entity the owner controls, personal expenses run through the business, discretionary spending a new owner would cut. Each is adjusted so the earnings reflect genuine operating economics.
The discipline this requires is not unique to private deals. Public companies reporting an adjusted earnings figure must reconcile it to the equivalent GAAP measure and may not present it more prominently, under the SEC guidance on non-GAAP financial measures — the same principle a buyer applies when they ask you to show the bridge from reported to adjusted. The gap between reported and normalized EBITDA is often large enough to move the valuation more than the multiple itself does. For a fuller treatment, see which EBITDA add-backs buyers accept and reject. If you walk into a conversation anchored on your reported EBITDA, you are often anchored to the wrong number.
Running that normalization yourself, even roughly, is one of the higher-return hours an owner can spend before a sale. It reframes the conversation from arguing about price to identifying the right buyer, because you already understand the number they will build. It surfaces legitimate adjustments a buyer might otherwise overlook, and it flags the aggressive ones a buyer will reject before they turn into friction during diligence.
EBITDA or SDE — which one applies to you?
There is a second earnings convention you will encounter, and using the wrong one produces a misleading result. SDE, or seller's discretionary earnings, is roughly EBITDA plus one full-time owner's salary. It is the standard for smaller, owner-operated businesses, where a single working owner is genuinely central to how the business runs.
The practical dividing line is scale and structure. Once a business has a real management team and the owner is one of several leaders rather than the whole operation, buyers use EBITDA. Below that, where the owner is effectively the business, SDE captures the full economic benefit a single operator extracts. The two conventions carry different multiple ranges, so they are not interchangeable. A short piece on EBITDA vs SDE and which applies to your business works through where the line falls and why it matters for your headline number.
For the rest of this guide, assume the EBITDA path, which is where most businesses of 5 million dollars in revenue and up will land.
Where does the multiple come from?
Once a buyer has a normalized earnings figure, they multiply it by a number: the multiple. If a business earns 2 million in normalized EBITDA and the applied multiple is five, the enterprise value is roughly 10 million. Simple arithmetic. The judgment is all in the multiple.
The starting point for that multiple is your industry. Different sectors trade in different ranges for structural reasons that have nothing to do with any individual business. Software businesses with strong retention command higher multiples than most because their revenue is recurring and their margins scale. Construction and trades tend to trade lower because earnings are project-based and cyclical. Healthcare services sit higher because of the stability of demand and the barriers created by licensing. These patterns are consistent enough that a buyer can anchor on a typical range for your sector before knowing anything else about you.
That range is exactly that, a range, not a fixed number. Where a specific business lands inside its sector's band, and whether it pushes above or falls below it, is decided by the factors in the next section. We deliberately do not publish exact multiple bands here, because a headline number lifted out of context does more harm than good; the point is to understand the drivers. For a qualitative tour of how the sectors differ and why, see how EBITDA multiples vary by industry, along with the deep dives on software and SaaS, manufacturing, and healthcare.
What moves your multiple up or down?
The industry range sets the neighborhood. Your own business decides the address. Two companies in the same sector with the same normalized EBITDA can land far apart, and the distance between them is almost entirely about risk and transferability. These are the factors buyers weigh most heavily.
Customer concentration. If one or two accounts drive a large share of revenue, a buyer prices in the risk that losing them would gut earnings. Concentration is one of the most common reasons a multiple comes in below what an owner expected. A broad, diversified customer base does the opposite and supports the upper end of the range.
Owner dependence. A buyer is purchasing a business, not a job. If the company cannot run without the current owner handling sales, key relationships, or daily decisions, the earnings are harder to transfer and the multiple suffers. A capable management layer that operates without the owner is one of the most reliable ways to lift value.
Recurring and repeat revenue. Earnings a buyer can count on next year are worth more than earnings that have to be won again from scratch. Contracts, subscriptions, and sticky repeat relationships all raise the quality of the earnings and, with it, the multiple.
Growth trajectory. Steady multi-year growth, not just one strong quarter, pushes the multiple toward the top of the range. It signals that the earnings a buyer is paying for are more likely to be larger, not smaller, under their ownership.
Scale. Larger absolute EBITDA tends to earn a premium of its own. Bigger businesses are usually more diversified, more resilient, and attractive to a wider pool of buyers, so the same quality of earnings is often valued more highly at 5 million of EBITDA than at 1 million. This is also why growing the earnings base and improving its quality compound: you get more EBITDA and a higher multiple applied to it. The dynamics specific to owners in the 3 to 5 million dollar range are worth reading if that is where you sit.
Every one of these is something an owner can influence, which is the genuinely useful part. The multiple is not handed down; it is earned, and most of the levers respond to work done well before any sale conversation begins.
If you want to see how these inputs translate into a range for your own business, our valuation calculator applies this same logic and returns an estimate you can react to.
A worked example: same earnings, different value
Picture two businesses in the same industry, each with the same normalized EBITDA of two million dollars.
The first sells to more than forty customers, none larger than a tenth of revenue. A capable management team runs daily operations, a meaningful share of revenue renews under contract each year, and the business has grown steadily for five years. A buyer looks at that and sees earnings that are diversified, durable, and transferable. They price it toward the top of the industry range, and they compete to win it.
The second earns the identical two million, but more than half of it comes from a single customer, the owner personally holds the key relationships and closes the major deals, and growth has been flat. A buyer sees the same headline earnings resting on a far shakier foundation. They price it toward the bottom of the range, attach conditions to the offer, or walk away.
Same industry, same EBITDA, materially different value. Nothing separates them except risk and transferability, and both are things the second owner could have worked on well before a sale. That gap, not the earnings figure itself, is where most of the value in an exit is won or lost.
How long does it take to change your number?
The durable levers take time, usually somewhere between one and three years to show up in the numbers a buyer will credit. Diversifying a customer base, building a management layer, and shifting revenue toward recurring relationships are real operational changes, not cosmetic ones. Buyers can tell the difference between a business that has genuinely lowered its risk and one that has been dressed up in the months before a sale, and they price the difference accordingly.
That is not a reason to wait. It is the reason to start early. The changes compound, and because they raise both the earnings and the multiple applied to them, beginning well ahead of any transaction is the single most reliable way to influence your eventual range. An owner who understands the method has a practical edge here: they know which specific changes a buyer will actually pay for, and they have the runway to make those changes count.
Why is the answer a range, not a single number?
When a buyer finally quotes value, an honest answer sounds like "somewhere in this band, depending on what we find," not "your business is worth 5.7 million." The range is not evasiveness. It carries real information, and collapsing it to a single number quietly throws that information away.
A proper range tells you four things at once: the buyer's central case, which is the midpoint; the downside if a known concern proves out, which is the low end; the upside if the strengths hold up, which is the high end; and the two or three factors that would move you between them. A single number tells you none of that, and once a precise figure lodges in an owner's head as a target, it is very hard to dislodge even when it was never justified.
There is also genuine uncertainty that no amount of analysis removes before a deal. A real offer reflects buyer-specific synergies, the structure of the transaction, and what diligence turns up. The range is the honest representation of that uncertainty. This is why our estimate, and any credible one, always shows a low, a midpoint, and a high together. The reasoning behind that choice is worth reading in full: why a buyer's offer is rarely a single number.
How do the different valuation approaches fit together?
You may have heard that there are three ways to value a business: the income approach, the market approach, and the asset approach. It is worth knowing how they relate, because the EBITDA-and-multiples method described here is really a blend of the first two.
The income approach values a business on the cash flow it produces, which is exactly what anchoring on normalized EBITDA does. The market approach values it by comparison to what similar businesses actually sell for, which is where the industry multiple comes from. Putting a market-derived multiple on an income-derived earnings figure is the everyday method for most private companies precisely because it draws on both. The asset approach, which values the business on the net worth of what it owns, mostly sets a floor and matters most for asset-heavy or underperforming businesses where the earnings do not justify a premium.
For a healthy, profitable operating business, the earnings-and-multiple view almost always governs. The asset view becomes the reference point only when a business earns too little to be worth more than its parts.
What this means for your own estimate
Put the pieces together and the method is straightforward, even if the judgment inside it is not. A buyer normalizes your earnings to reflect what the business truly produces, anchors on a multiple that is typical for your industry, moves within that range based on how durable and transferable your earnings are, and expresses the result as a range rather than a false-precision number.
Understanding that sequence changes what you can do with it. You can see which of your own characteristics are pulling you up the range and which are holding you down, and you can work on them. You can tell the difference between a buyer who is doing the analysis and one who is rounding you off. And you can treat any single figure, including the one this site produces, as a directional starting point for a more specific and confidential conversation rather than as an appraisal.
A directional range built this way answers a different question from a formal appraisal, which is performed to a defined standard for a defined purpose such as a tax filing or litigation; the IRS publishes its own valuation guidance and job aids reflecting the rigour those contexts demand. To see how your inputs shape a range, estimate your valuation range with the calculator. It uses the same EBITDA-and-multiples logic described here and returns a range and midpoint, never a single number. Treat the result as a grounded place to start, not a formal appraisal, and use it to decide which questions are worth asking next.
