The short answer: Your business is not worth one fixed number. It is worth a range the market sets, based on your normalized earnings, your industry’s typical multiple, and how much risk a buyer sees. This 10-minute self-assessment walks you through five questions that get you to a credible range. An online “business valuation calculator” cannot, and here is why.
“What’s my business worth?” is the first question almost every owner asks, and it is usually the one answered worst. Type the question into Google and you will find a dozen “business valuation calculators” promising an instant figure from three inputs. The number they return is, at best, a starting guess and, at worst, misleading enough to cost you a deal.
Here is the more useful truth. The value of a privately held company is a range, set by buyers, under a defined standard of value, and adjusted for the specific risks of your business. You can get to a defensible range yourself in about 10 minutes. You just need the right five questions instead of a black-box calculator. This matters: the Exit Planning Institute reports that roughly 80% of a typical owner’s net worth is locked inside the business, yet only 20% to 30% of companies that go to market actually sell. Knowing your real number early is how you end up in the group that does.
Step 1: Pin down your real earnings (2 minutes)
Start with trailing-twelve-month (TTM) revenue and, more importantly, your normalized earnings. Buyers do not pay for revenue. They pay a multiple of the profit the business actually produces for an owner, which is rarely the net income on your tax return.
For most lower-middle-market companies, that earnings number is either EBITDA (earnings before interest, taxes, depreciation, and amortization) or, for smaller owner-operated businesses, Seller’s Discretionary Earnings (SDE), which adds back the owner’s salary and benefits. Pull your last 12 months of profit and loss and write down the single earnings figure that best describes what the business throws off. You will refine it in Step 3.
If your financials are not clean enough to trust this number, that is its own signal. Buyers discount what they cannot verify. Our guide on how to prepare your business for sale covers the financial cleanup that protects your value.
Step 2: Find your industry’s multiple range (2 minutes)
Value in the private market is most often estimated with the Market Approach: take your normalized earnings and apply a multiple drawn from what comparable businesses actually sold for. The multiple is not arbitrary. It reflects your size, industry, and growth.
For a directional anchor, IBBA and M&A Source Market Pulse data from late 2024 showed lower-middle-market deals in the $5M to $50M range trading around 4 times EBITDA, while smaller businesses in the $1M to $5M range traded closer to 2.8 to 3 times SDE. Treat those as gravity, not gospel. A defensible multiple for your specific company comes from real comparable transactions, selected carefully.
In our own engagements, when we pull comparable deals, we apply a discipline often called the 5/10/10 rule: ignore transactions older than five years, and ignore comparables more than 10 times larger or 10 times smaller than the subject business. That keeps the comparison honest. A precise, industry-by-industry multiples guide is coming later this quarter. For now, pick the range that fits your size band and move on.
Step 3: Add back what the business really earns (2 minutes)
Now refine the earnings figure from Step 1 by normalizing it. Normalizing (also called recasting) strips out expenses that would not transfer to a new owner and corrects items that are not at market rates. This is where many owners undervalue themselves by tens of thousands of dollars.
Walk through three categories:
- Owner compensation: adjust your salary to what it would cost to hire a manager to do your job. If you pay yourself well above market, that excess is added back. If you pay yourself nothing, a market salary is subtracted.
- Discretionary expenses: personal vehicles, travel, family members on payroll, and other perks the business runs through it that a buyer would not continue.
- Non-recurring items: one-time legal settlements, a single large equipment repair, or storm recovery costs that will not repeat.
When we recast a set of financials, owner compensation and discretionary perks are almost always where the hidden value sits, and we have seen a clean recast lift adjusted earnings by a third or more. The result is your adjusted earnings, and it is the number your multiple should be applied to. Be honest and be documented. Every add-back you cannot prove is one a buyer will strike in diligence.
Step 4: Discount for risk (2 minutes)
Two businesses with identical earnings can be worth very different amounts. The difference is risk. The more a buyer worries the cash flow will not survive the transition, the lower the multiple they will pay. This is the single biggest lever most owners ignore.
Score your business honestly against the risk factors buyers scrutinize most:
- Owner dependence: if the business stops without you, a buyer is buying a job, not a company. This is the most common value killer in the lower middle market.
- Customer concentration: if one client is 20% or more of revenue, the buyer prices in the risk of losing it.
- Transferability: assignable leases, contracts, and licenses, plus documented systems, all raise the multiple. Handshake arrangements lower it.
- Recurring revenue and growth: predictable, growing revenue earns a premium over lumpy or declining revenue.
This is not theory. We once sold two remediation companies with nearly identical earnings and nearly identical net profit. One sold for about two times earnings. The other sold for close to five. The difference came down almost entirely to owner involvement. The first owner ran everything himself, taking the calls, managing every job, handling every customer, even when the work was out of town. The second owner lived out of state and spent maybe five to 15 hours a week on the business, coaching a strong team that made the decisions. One owner was selling a job. The other was selling a company that runs without him. The market priced that difference, and a single industry multiple would have valued one far too low and the other far too high.
The payoff for reducing these risks is real and measurable. The Value Builder System, drawing on a dataset of more than 30,000 businesses, found that companies scoring 80 or above on its assessment received offers roughly 71% higher than average-scoring businesses with similar financials.
Step 5: Sanity-check against the real market (2 minutes)
Finish by reality-testing your range. Multiply your adjusted earnings from Step 3 by the low and high ends of your multiple from Step 2, then shade the result up or down based on the risk picture from Step 4. That gives you a credible value range, not a single false-precision number.
Then ask the only question that ultimately settles value: what would a real buyer pay today? No self-assessment replaces an actual market test. The advantage of a properly run, confidential process is that you find out fast. With our Structured Sale™ approach, owners typically know what the market thinks in under 30 days. If you want the advisor-led version of this exercise before you ever go to market, see what your business is worth before you list.
Why a business valuation calculator isn’t a valuation
A 10-minute self-assessment is a great way to orient yourself. It is not a valuation, and neither is any online calculator. The difference is not effort. It is rigor and standards.
A professional engagement begins by fixing the standard of value (fair market value, investment value, and others mean different things and produce different numbers) and the purpose of the work. Performed under NACVA Professional Standards methodology, the analysis then weighs the income, market, and asset approaches and reconciles them with documented judgment. The deliverable is either a Calculated Value, from a more limited Calculation Engagement, or a Conclusion of Value, from a full Valuation Engagement. A calculator gives you none of that, which is why it cannot be defended to a buyer, a lender, the IRS, or a court. For the full picture, read our complete owner’s guide to business valuation.
That gap between the two remediation deals is exactly why a cookie-cutter valuation is dangerous. The quick multiple-times-EBITDA approach common across the brokerage industry is not in the same category as a bank-grade valuation. An engagement performed under NACVA Professional Standards methodology produces a result laid out in clear, defined terms. Another qualified professional could pick it up and reproduce it, because it is built on a framework that explicitly measures the risk of the specific company being valued. That rigor is why SBA lenders rely on valuations built to these standards. A real valuation is not cheap, and professional judgment always plays a part, but if you are about to make a major decision that turns on what your business is worth, have a professional do the work.

Frequently asked questions
You can estimate a credible value range yourself by normalizing your earnings, applying an industry-appropriate multiple, and adjusting for risk. That is enough to orient your planning. It is not a defensible valuation for a sale, loan, tax, or legal matter, which requires a professional engagement under recognized standards.
Online business valuation calculators are rarely accurate because they ignore the variables that drive value: normalized earnings, comparable transaction selection, and company-specific risk. They apply a generic multiple to an unadjusted number. Treat the result as a rough starting guess, never as the value of your business.
There is no single multiple for a business. Recent IBBA and M&A Source data showed lower-middle-market deals around 4 times EBITDA and smaller businesses closer to 2.8 to 3 times SDE, but your actual multiple depends on size, industry, growth, and risk. Comparable transactions, selected carefully, set the real number.
A Calculation of Value is typically delivered in 2 to 3 days, and a full Conclusion of Value in 1 to 2 weeks, with rush options available. A market test through a confidential sale process tells you what buyers will actually pay, often within 30 days of going to market.
