To value a small business, most buyers and advisors start from its Seller's Discretionary Earnings (SDE) or EBITDA and apply an industry multiple, then sanity-check that figure against comparable business sales, and for larger or fast-growing companies, a discounted cash flow (DCF) analysis. The right method depends on the business's size, how stable its earnings are, and why you need the number (a sale, financing, or planning). The sections below walk through each method and what moves the final figure.
If you're not currently thinking about selling your business, you might assume that assigning a financial value to your company isn't necessary. However, it's still prudent to ask yourself how much is my business worth? since there are plenty of other reasons to learn best practices for valuing your business, and maybe even to conduct an actual valuation. These reasons include applying for a small business loan, setting up an ESOP, trying to find investors, or simply understanding your business and its growth trajectory.
Valuation 101
There are a variety of factors that go into calculating the valuation of a company, and these can be subjective depending on who is doing the evaluating and what weight they are giving to each factor. However, the factors themselves are somewhat objective and are helpful to understand before embarking on the small business valuation process.
Seller's discretionary earnings (SDE): SDE is a common way to measure the earnings of a small business. Buyers often look at this number as the total financial upside that a single owner would earn annually. The number is calculated by taking the business's pre-tax net income, then adding in the owner's salary plus all discretionary expenses (everything from meals to vehicles reported as business expenses), including non-recurring and personal expenses. Depreciation and amortization are also included in an SDE calculation, along with any interest expenses.
The final number can give owners and potential buyers a more accurate assessment of earnings potential and valuation. However, SDE doesn't wholly or accurately measure cash flow and also doesn't take into account taxes, working capital, and other expenses.
Earnings before interest, taxes, depreciation, and amortization (EBITDA): EBITDA provides an indication of a company's operational profitability, though it's important to remember that it's only a snapshot of a narrow slice of a business's health. It can be helpful to have a metric that excludes interest, taxes, depreciation, and amortization as a point of comparison when evaluating more than one business's value, especially if they're in the same industry. EBITDA is a primary metric that lenders use to decide whether a given business is a good candidate for a loan; this is directly related to the company's ability to expand and grow.
Tangible vs. intangible assets: Assets are things of value to a business that represent one measure of what that business is worth. Tangible assets are often physical, and they are always measurable. They include things like office real estate and the furniture that is in those offices. Intangible assets are non-physical and can be subjective when it comes to applying a quantitative value. Examples might include name brand value, an established and loyal customer base, email lists, and trademarks.
Comparable businesses (comps): Though somewhat subjective, comparables are an important factor when valuing a small business. The approach involves comparing a given business to other businesses that are similar in industry, market, size, revenue, and profitability. It's also helpful to look at what similar businesses have sold for, but timing is important here; you want to look at recent sales or listings, as opposed to comparing a business today with one that was sold a few years ago.
The more granular you can get in terms of similarity, the better. For example, comparing a business on a main thoroughfare with many pedestrians to a business that is in a less populated area is going to affect the accuracy of the comparison, especially if the latter business can easily be moved to a more highly trafficked street.
How to Value a Small Business
There are many ways to value a business, some of which are more accurate than others and vary depending on market conditions and industry.
Multiples method: The multiples method values a business by multiplying its earnings by an industry-specific multiple, and it is possibly the simplest approach. It can take into account a multiple of business earnings, a multiple of EBITDA, a multiple of SDE, or some combination of all three.
Income-based valuation: Income-based valuation estimates a business's worth from the income it generates, most often through a Discounted Cash Flow (DCF) analysis that values a company based on future cash flow, adjusted to current value. This is done by forecasting cash flow for the next few years, then using a formula to calculate the present day value of those cash flows.
Because the value is heavily weighted on estimates of future cash flow, there is significant room for error. For more risk averse buyers, this method might be more suitable when assessing stable companies with predictable cash flows.
Market-based valuation: Market-based valuation assesses comparable businesses and recent sales of those companies, while taking into account current market forces. This method is especially helpful for hyperlocal businesses and companies in industries where there are many comparables to evaluate.
Assets-based valuation: Assets-based valuation focuses on a business's total assets minus its total liabilities (adjusted net assets). For example, you might add up the value of equipment, inventory, and trademarks, then subtract debt, depreciation, etc. Finally, you adjust the number to fair market value. If an owner or buyer is looking to liquidate assets, they might focus more on the net cash that they would acquire if all assets were sold and liabilities were paid off.
It's common (and advisable) to use more than one method to cross-check business valuations and get a more comprehensive view of a business's appraisal.
How Are Small Businesses Valued?
In practice, most small businesses are valued on their earnings rather than on revenue or assets alone. You start with SDE or EBITDA, apply the multiple that is normal for the industry, then cross-check that figure against what comparable businesses have recently sold for. An owner who wants to valuate a business can work in that same order: the earnings number sets the base, the multiple reflects the industry, and the comparable sales keep the result tied to what the market is actually paying. Where those three disagree sharply, the gap is usually worth investigating before you valuate the business any further.
How to Determine the Value of a Small Business
Three questions decide almost every small business valuation, and they are worth separating because owners usually answer the third one with the first one.
What does the business actually earn for its owner? Start from SDE for an owner-operated business or EBITDA for one with management in place. The number matters less than the consistency of how you get to it: add back what a new owner genuinely would not pay, and nothing else.
What multiple does a buyer apply to that number? This is where size, risk and industry enter. Two businesses earning the same amount rarely sell for the same amount.
What does the buyer have to replace? If the owner is the top salesperson, the estimator and the only person the crews will take direction from, a buyer is not purchasing earnings. They are purchasing a job with a debt attached, and they price it that way.
The first question is arithmetic. The second and third are judgement, and they are the reason two credible valuations of the same business can differ by more than the owner expects.
Revenue Bands: Why Size Changes the Multiple
Buyers and brokers routinely sort businesses into revenue bands before they price anything, and a business that moves up a band is often worth more per dollar of earnings than it was the day before. The banding is not arbitrary and it is not a rule you can look up. It is a shorthand for four things that genuinely change as a business gets larger.
The buyer pool widens. Very small businesses sell to individuals buying themselves a job. Larger ones attract search funds, family offices and strategic buyers who compete with each other, and competition moves price.
Financing gets easier. A larger, steadier earnings base supports lending, which means a buyer can pay more without writing a larger cheque themselves.
Key-person risk falls. A business with a management layer survives the owner leaving. One without a management layer is largely the owner.
Customer concentration usually improves. Losing your biggest customer is a different event at four customers than at forty.
Here is the arithmetic that makes the banding matter, with the multiple held as a variable rather than a claim:
A business earning $500,000 of SDE, valued at a multiple of M, is worth $500,000 × M. If moving from one band to the next moves the multiple by a single turn, the value moves by $500,000 — the same earnings, a different price, entirely because of how the business is structured around its owner.
That is why the useful question is rarely “what multiple does my industry get”. It is “what would have to be true for a buyer to apply the higher end of the range to us”, and the answers are almost always operational: documented processes, a management layer that does not include you, contracts rather than relationships, and a team that stays through the transition.
There is no lookup table for this. Anyone quoting a band-to-multiple figure without naming the industry, the year and the data set behind it is quoting a rule of thumb, and rules of thumb are where valuations go wrong. For a number you can act on, ask a valuation professional for comparable sales in your industry.
The Four Ways a Small Business Gets Valued, and When Each One Applies
A small business valuation is rarely one number, and most owners asking how to value a small business are given one anyway, with no explanation of where it came from. There are four common approaches, they answer different questions, and the gap between them is often larger than the gap between two buyers.
Seller's discretionary earnings multiple. The most common method for owner-operated businesses under a few million in revenue. Normalized profit, with the owner's salary and personal expenses added back, multiplied by a figure that reflects risk and transferability. It answers "what would this business earn a new owner who runs it themselves."
EBITDA multiple. The same logic without adding the owner's compensation back, used once a business is large enough to run without the owner in it. The distinction is not academic: a business valued on SDE and the same business valued on EBITDA can differ by the owner's entire salary, and which one applies depends on whether the buyer intends to work in the business or hire someone to.
Asset-based valuation. Tangible assets less liabilities. It sets the floor rather than the price for a profitable business, and it becomes the operative number when earnings are inconsistent or the value genuinely sits in equipment, inventory and property rather than in cash flow.
Rule of thumb multiples. Industry shorthand such as a multiple of annual revenue or of monthly recurring billings. These are useful for a first conversation and dangerous as a basis for a deal, because they ignore the two things buyers actually price: how concentrated the customer base is, and how much of the business walks out with the owner.
Why the same business produces different numbers
The methods disagree because they answer different questions, so before comparing valuations it is worth knowing which question was asked. A valuation prepared for a sale, one prepared for a buy-sell agreement between partners, and one prepared for estate planning can all be defensible and none of them will match.
For a trades or service business, three factors move the number more than the method does: whether revenue is recurring or project-by-project, whether the largest customer represents a manageable share of it, and whether the business runs without the owner on site. A business that scores well on all three is valued closer to an EBITDA multiple. One that scores poorly on all three is valued closer to its assets, whatever the rule of thumb suggests.
Common Questions
How do you determine the value of a small business?
Start from what the business earns for its owner, SDE for an owner-operated business or EBITDA where management is already in place, then apply a multiple that reflects size, risk and industry, then adjust for what a buyer would have to replace. The earnings figure is arithmetic and the multiple is judgement, which is why two credible valuations of the same business can differ.
Why do bigger businesses sell for a higher multiple?
Because size changes four things buyers price: the pool of buyers competing, how easily the purchase can be financed, how much of the business walks out the door with the owner, and how concentrated the customer base is. A business that moves into a higher revenue band is usually being priced for lower risk, not for the revenue itself.
