Ask ten founders what their business is worth and you’ll get ten different numbers, and most of them will be wrong. Not because these founders are careless, but because they’re guessing using the wrong inputs entirely: revenue instead of profit, hope instead of comparable sales, or a number a friend’s business sold for that has almost nothing to do with their own.

Knowing your real number isn’t just useful when you’re ready to sell. It changes how you run the business today, what you invest in, and whether you walk away from an offer that’s actually good or hold out for one that never comes. Here’s how to find your actual number, not the one you’ve been telling yourself.

I’ve sat across the table from founders on both ends of this problem. Some walked away from genuinely strong offers because they’d attached themselves to an inflated number with no real basis. Others accepted offers well below what their business was actually worth, simply because they’d never done the work to find out. Both mistakes come from the same root cause: never treating valuation as something you actually calculate, rather than something you feel.

The most common valuation mistake is treating top-line revenue as a proxy for what a buyer will pay. It isn’t. Buyers pay for profit, and more specifically, for the profit that will keep showing up after you leave. A business doing three million in revenue with thin, inconsistent margins can be worth far less than a business doing one million with clean, predictable profit.

Start with your seller’s discretionary earnings or EBITDA, depending on your business size, not your revenue line. This is the number buyers actually build their offer around. I have written before about the biggest mistake founders make when building a business , and confusing revenue with value tops that list every time.

Seller’s discretionary earnings, often shortened to SDE, adds back your owner salary, personal expenses run through the business, and one-time costs, so you can see what the business actually generates before you take money out of it. For businesses under a few million in revenue, this is usually the number buyers and their advisors care about most, far more than the revenue figure on your top line. Get comfortable calculating it accurately, because a sloppy SDE calculation is one of the fastest ways to lose credibility with a serious buyer before negotiations even begin.

Multiples Are A Starting Point, Not A Formula

Once you know your true profit number, the next step is applying an industry multiple, but this is where founders often go wrong in the opposite direction, treating a generic multiple they read online as gospel. Multiples vary enormously by industry, business model, growth rate, and how dependent the business is on you personally.

A service business that requires the founder’s daily involvement might sell for two to three times earnings. A business with recurring revenue, a strong team, and diversified clients can command five, six, or more. The gap between those numbers isn’t random. It’s a direct reflection of risk, and buyers price risk relentlessly.

These are the same financial strategies to maximize small business value that separate a two times multiple from a five times multiple, and most of them have nothing to do with growing revenue faster. They have to do with making the business less risky to own.

A useful exercise is to research recent, comparable sales in your specific industry and size range, not the aspirational multiples you see quoted in general business media. Talk to a business broker or M&A advisor who works specifically in your space. They see real transaction data that never makes it into public articles, and that data will ground your expectations in reality rather than in whatever multiple sounds most flattering.

The Four Levers That Actually Move Your Number

If you want to know what genuinely changes your valuation, it comes down to four levers: owner independence, revenue diversification, growth trajectory, and financial cleanliness. Every dollar you invest improving these four areas moves your multiple, not just your revenue.

Owner independence matters most, and it’s usually the hardest to fix quickly. A business that runs without you is inherently less risky to a buyer than one where you personally hold every key relationship. Revenue diversification matters almost as much. If one client represents forty percent of your income, buyers will discount heavily for that concentration risk, regardless of how strong that relationship feels to you today.

Growth trajectory tells a buyer what they’re actually purchasing: momentum, or a plateau they’ll have to work hard just to maintain. And financial cleanliness, the boring stuff, consistent bookkeeping, minimal personal expenses running through the business, clear records, determines how fast and how confidently a buyer can trust the number you’re presenting them in the first place.

Think of these four levers as a diagnostic, not a checklist to complete once. Score yourself honestly on each one every six months. Most founders find that one lever is dramatically weaker than the other three, and that weak lever is usually the single highest-leverage place to focus, because buyers, and their advisors during due diligence, will find it regardless of how well everything else is dressed up.

Get A Real Valuation, Not A Guess

A back-of-envelope estimate is fine for planning purposes, but if you’re seriously considering a sale within the next two to three years, get an actual independent valuation from someone who does this professionally. It typically costs a few thousand dollars and it will save you from two expensive mistakes: underpricing a business you spent a decade building, or overpricing it and scaring away every legitimate buyer who looks at your numbers seriously.

A good valuation doesn’t just give you a number. It gives you a breakdown of exactly which factors are dragging your multiple down, which is far more useful than the number itself. That breakdown becomes your roadmap for the next twelve to twenty-four months, showing you precisely where to focus if you want a materially higher number by the time you actually list the business.

Expect the valuation process itself to take a few weeks, not a few days, if it’s done properly. A rushed valuation based purely on an online calculator will give you a number, but not necessarily an accurate or defensible one. The businesses that sell fastest, and closest to their asking price, are almost always the ones whose founders got a rigorous valuation well before they needed one, not the week before they listed.

Revisit that valuation every twelve to eighteen months. Markets shift, your business changes, and a number that was accurate two years ago may already be stale. I always encourage founders to also ask how you know if your business is big enough to sell at the same time, because size and value are related but not identical questions, and both matter to how a buyer will evaluate you.

Watch For The Traps That Skew Your Number

A few common traps distort valuations in both directions. Founders who recently had one exceptional year sometimes assume that year represents their new baseline, when a buyer will more likely average the last three years, or discount the outlier entirely. On the flip side, founders coming off a genuinely rough year sometimes assume their business is worth far less than it is, forgetting that buyers evaluate trend and trajectory, not just the most recent twelve months in isolation.

Another trap is comparing yourself to a competitor’s publicized exit without knowing the real terms behind it. Headline numbers rarely reflect the full structure of a deal, how much was cash at close versus earnout, versus seller financing spread over years. A seven-figure headline can mean something very different depending on how that number was actually paid out, so treat other founders’ announced numbers as interesting data points, not as a benchmark to hold your own valuation against.

Why Most Founders Underestimate Their Own Number

Here’s something counterintuitive I see constantly. Founders are far more likely to underestimate their business’s value than to overestimate it, especially founders who built something scrappy and are used to thinking of their business as smaller or less impressive than it actually is.

You’re too close to see it clearly. You know every flaw, every near-miss, every month that almost didn’t work. A buyer doesn’t see any of that. They see three years of financials, a functioning system, and a market opportunity they didn’t have to build from scratch. That gap between how you see your business and how a buyer sees it is often the difference between an offer that surprises you and one you never even sought out.

This is exactly why these essential steps to maximize your business value work even for founders who think their business is too small or too ordinary to be worth much. Buyers are looking for something specific: a system that works and can keep working without you. If you have that, your number is probably higher than you think.

I see this most clearly with founders who built something quietly profitable without ever chasing headlines or rapid growth. They assume nobody would want to buy a modest, steady, unglamorous business. In reality, buyers actively seek out exactly that profile, because boring and predictable is far easier to underwrite than exciting and volatile. If your business has been quietly grinding out consistent profit for years, that consistency itself is a valuable asset, not a limitation.

What To Do With Your Number Once You Have It

Once you know your real number, use it. Not to obsess over daily, but to check in against once or twice a year, alongside a clear sense of what number would actually change your life if someone offered it to you.

That second number matters just as much as the valuation itself. Plenty of founders get an accurate valuation, receive an offer that matches it almost exactly, and still turn it down because they never did the work of figuring out what number would genuinely be worth walking away for. Don’t let that be you. Do both pieces of math well before an offer ever lands in your inbox, so when it does, you can evaluate it clearly instead of scrambling to figure out what you actually want in the moment.

Knowing your number isn’t about obsessing over a spreadsheet. It’s about negotiating from evidence instead of emotion, and about recognizing a genuinely good offer the moment it appears instead of doubting yourself out of it.

There’s a quieter benefit too, one most founders don’t expect. Once you know your real number and understand exactly what moves it, you stop running your business on instinct alone and start running it with a clear target. Every decision, from a new hire to a pricing change to whether you take on that demanding client, can be weighed against a simple question: does this make my business more valuable and less dependent on me, or does it just make this quarter feel busier? That single lens changes how founders operate long before any sale is on the table, and it tends to make the business better to run in the meantime, whether or not you sell it next year or in ten.

Start this quarter. Calculate your SDE honestly, research real comparable multiples in your industry, and score yourself against the four levers. You don’t need a buyer knocking on your door to benefit from knowing exactly what you’ve built.
