How much is your business worth? It is the question anyone faces who wants to sell a business, buy one, or simply understand the value of what they've built. For small owner-operated businesses, the most used method is valuation based on SDE (Seller's Discretionary Earnings): you calculate the true cash flow the business generates for a single owner-operator and multiply it by an industry multiple. The SDE business valuation calculator rebuilds the SDE starting from net profit and adjustments (add-backs), applies the multiple and gives you an estimate of the business value, with the add-back share and a judgment on the multiple. It is the starting point for pricing the sale or purchase of a small business.

What the SDE business valuation is

The SDE valuation is the standard method to estimate the value of small businesses run directly by the owner (shops, restaurants, practices, small service or manufacturing companies). The idea is simple: a business is worth a function of the income it can generate for its owner. But the accounting net profit doesn't tell the whole story, because in a small business the owner often "mixes" business income and personal income: they pay themselves a salary, charge partly personal expenses to the company, and the financial statement contains non-cash or extraordinary items. The SDE corrects all this, rebuilding how much money the business really makes available to a single owner who runs it. Multiplying the SDE by a typical industry multiple gives an estimate of the market value. It is the common language of brokers, buyers and sellers of small businesses worldwide.

How it is calculated

The calculation has two steps. First: you rebuild the SDE starting from net profit and adding the adjustments (add-backs): the owner's compensation, their personal benefits, one-off extraordinary expenses, and depreciation and interest. Second: you multiply the SDE by the industry multiple. Example: net profit 40,000, owner's compensation 60,000, personal benefits 10,000, one-off expenses 5,000, depreciation and interest 15,000. The SDE is 40,000 + 60,000 + 10,000 + 5,000 + 15,000 = 130,000. With a multiple of 2.5×, the estimated business value is 130,000 × 2.5 = 325,000. The calculator also shows the total add-backs (90,000 in this case) and their share of the SDE, an important indicator of the "quality" of the earnings.

What the SDE (seller's discretionary earnings) is

The SDE, or seller's discretionary earnings, is the total income a business generates for a single owner-operator, before taxes, interest, depreciation and that owner's compensation. In practice it answers the question: "if I bought this business and ran it myself, how much money would I have available each year, between the salary I'd pay myself and the profit?". This is why you start from net profit and "add back" all the items that represent a benefit for the owner or that don't reflect the true cash potential of the business. The SDE is the most suitable metric for small businesses, where the owner is also the main operator. For larger businesses, where ownership is separate from management, EBITDA is used instead, which doesn't include management compensation.

Add-backs: the adjustments to profit

The add-backs are the items added to net profit to rebuild the SDE. The main ones are: the owner's compensation (because the new owner might pay themselves differently or run it themselves); the personal benefits charged to the company (company car for personal use, personal entertainment expenses, phone, etc.); the one-off extraordinary expenses (a concluded lawsuit, a relocation, a non-recurring consultancy); the depreciation (non-cash costs) and interest (which depend on the financial structure, not the operating business). The goal is to show the "normalized" cash potential of the business. Beware, though: the add-backs must be legitimate and documentable. Adding expenses that are actually necessary to the business (and that the new owner will have to bear anyway) artificially inflates the SDE and leads to an unrealistic valuation that the buyer, in due diligence, will contest.

The SDE multiple

The SDE multiple is the factor by which you multiply the SDE to get the value. For small businesses it typically ranges between 2× and 4×, but varies a lot by industry, size, growth and risk. A multiple of 2.5× means the business is worth about two and a half years of its discretionary earnings. The multiple reflects how much a buyer is willing to pay upfront for that income stream: the more solid, stable, growing and transferable (little owner-dependent) the business, the higher the justified multiple. A small, volatile business very tied to the owner's person will have a low multiple (1.5-2.5×); a larger business, with recurring revenue, recognized brand and autonomous management, can justify 3.5-4.5× or more. Choosing the right multiple is the most delicate and subjective part of the valuation, and it is where negotiations concentrate.

Value as the multiple varies

Here is how the estimated business value changes as the multiple varies, with an SDE of 130,000:

With the same SDE, the value triples going from 1.5× to 4.5×. This is why the choice of multiple — that is the assessment of the quality and risk of the business — matters as much as the calculation of the SDE itself.

SDE versus EBITDA

The key difference between SDE and EBITDA lies in the treatment of the owner's compensation. The SDE includes (adds back) the owner's compensation, because it assumes a single owner-operator who substitutes their own work for that of an employee. EBITDA does not add back management compensation, because it assumes the company keeps paying managers. Consequently, for the same business the SDE is higher than EBITDA (by the amount of the owner's compensation). The rule of thumb: SDE is used for small businesses (below a certain turnover, where the owner works in the business); EBITDA for medium-large ones (where management is delegated to paid managers). Using the wrong metric, or comparing an SDE multiple with an EBITDA multiple, leads to gross errors: EBITDA multiples are higher precisely because applied to a lower base (the EBITDA). Make sure you are consistent between metric and multiple.

The add-back share and earnings quality

The add-back share of the SDE — how much of the SDE comes from adjustments rather than accounting profit — is an important indicator of the quality of the valuation. If net profit is 40,000 and the SDE is 130,000, the add-backs are worth 90,000, about 69% of the SDE: most of the "income" for the buyer comes from the adjustments, not the accounting profit. A very high share is not in itself wrong (it is normal in micro-businesses, where the owner's compensation is the main item), but it requires more attention: it means the valuation depends heavily on those add-backs being real and sustainable. A prudent buyer scrutinizes every adjustment, and inflated or questionable add-backs make trust and valuation collapse. A business with a high "real" profit and few add-backs offers a more solid and credible base than one that stands almost only on adjustments.

How to estimate the right multiple

Estimating the multiple is the hardest part. You start from the industry average multiples (available from brokers, comparable transaction databases and trade associations) and adjust them for the specific characteristics of the business. Raising the multiple: revenue growth, high and stable profitability, recurring or contracted revenue, diversified customer base, brand and reputation, documented processes, low owner dependence, favorable industry trend. Lowering it: declining or volatile revenue, thin margins, concentration on few customers, strong owner dependence, expiring contracts, declining industry, disputes or unknowns. The multiple is not an objective number but a synthesis of the risk and prospects perceived by the buyer. In the calculator, try different multiples to see the plausible value range: a realistic valuation is almost always a range, not a single number.

Typical multiples by business type

Here are some indicative SDE multiple ranges by category (guideline values, not fixed rules):

These ranges vary a lot by country, size and market moment. Use them as a starting point, not as absolute truth: the real valuation depends on the specific fundamentals of the business and on the comparison with recent comparable transactions.

Factors that raise or lower the multiple

The multiple is the synthesis of many quality and risk factors. Growth: an expanding business is worth more than a stagnant or declining one. Revenue recurrence: subscriptions, multi-year contracts and loyal customers are worth more than spot sales. Diversification: depending on a single large customer or supplier is a risk that lowers the multiple. Transferability: documented processes, competent staff and a non-essential owner raise the multiple. Profitability and margins: high and stable margins are worth more than thin and volatile ones. Industry and market moment: some industries are more in demand and liquid than others. Finally, the quality of the documentation: clear financials and an SDE well supported by documentable add-backs increase trust and price. Each factor moves the multiple up or down relative to the industry average.

Owner dependence

Owner dependence (sometimes called key-man risk) is perhaps the factor that most influences the multiple of small businesses. If the business "is" the owner — because customers come for them, because only they know the processes, because without them revenue would collapse — then the buyer is purchasing a job, not a transferable company, and the multiple drops. Conversely, a business that works even without the daily owner — with autonomous employees, documented procedures, institutionalized customer relationships — is much more valuable and transferable, and justifies a higher multiple. This is why those who want to sell well should work for years to make themselves "non-essential": delegate, document, build a team. Paradoxically, the less the business depends on you, the more it is worth. The calculator doesn't directly measure this dependence, but it is reflected in the choice of multiple: low dependence → higher multiple.

Factors in the multiple

Here is a summary of how the main factors move the multiple:

A realistic valuation starts from the industry average multiple and adjusts it up or down according to these factors. Two businesses with the same SDE can be worth very differently depending on their quality and risk profile.

From valuation to sale price

The SDE valuation is a starting point, not the final price. The real price emerges from negotiation and depends on factors the calculation doesn't capture: how motivated the seller is, how many interested buyers there are, the payment terms (cash upfront is worth less than installments or earn-outs), what is included (real estate, inventory, brands), the due diligence that can revise the SDE downward, and market and credit conditions. Often the price is built with a fixed part plus variable components (earn-outs tied to future results) to bridge the gap between the two parties' expectations. The SDE valuation serves to establish a credible reference range and to structure the discussion on rational bases, avoiding prices pulled out of thin air. But the "true" value is what a real buyer is willing to pay and a seller to accept.

How the calculator works

Enter the business's annual net profit, the owner's compensation, their personal benefits, the one-off extraordinary expenses, the depreciation and interest, and the SDE multiple you consider appropriate. The calculator rebuilds the SDE, applies the multiple and gives you the estimated business value, the total add-backs and their share of the SDE, with a judgment on the multiple. In a few seconds you have an estimate of your business's value and understand how much of the valuation depends on the adjustments.

The data you need

You need six data. The annual net profit (it can be low or even negative in a business where the owner pays themselves a lot). The owner's compensation (salary and personal drawings). The personal benefits charged to the company (car, mixed expenses, etc.). The one-off, non-recurring extraordinary expenses. The depreciation and interest (from the income statement). The SDE multiple: start from your industry's average multiple and adjust it for growth, recurrence and owner dependence. All add-backs must be legitimate and documentable: an inflated SDE leads to a valuation that due diligence will dismantle.

Frequently asked questions

What is the SDE business valuation?

It is the standard method to estimate the value of small owner-operated businesses: you calculate the SDE (seller's discretionary earnings) and multiply it by an industry multiple. It is the common language of brokers, buyers and sellers of small businesses.

How is it calculated?

SDE = net profit + owner's compensation + personal benefits + one-off expenses + depreciation and interest. Value = SDE × multiple. Example: SDE 130,000 × 2.5 = 325,000. The calculator rebuilds the SDE and applies the multiple you enter.

What is the SDE (seller's discretionary earnings)?

It is the total income the business generates for a single owner-operator, before taxes, interest, depreciation and the owner's compensation. It answers: "how much would I have available each year if I bought and ran this business myself?".

What are add-backs?

They are the adjustments added to net profit to rebuild the SDE: owner's compensation, personal benefits, one-off expenses, depreciation and interest. They must be legitimate and documentable: inflated add-backs lead to a valuation that due diligence will dismantle.

What multiple should I use?

For small businesses usually 2×-4×, but it depends on the industry and quality. Start from your industry's average multiple and adjust it: higher for growth, recurring revenue and low owner dependence; lower for risk and volatility. Try a range, not a single number.

What is the difference between SDE and EBITDA?

The SDE includes (adds back) the owner's compensation, EBITDA doesn't. So for the same business the SDE is higher. SDE is used for small owner-operated businesses, EBITDA for medium-large ones with paid management. Don't confuse an SDE multiple with an EBITDA one.

What does a high add-back share mean?

That most of the SDE comes from the adjustments and little from the accounting profit. It is normal in micro-businesses, but requires attention: the valuation depends heavily on those add-backs being real and documentable. A prudent buyer scrutinizes them one by one.

Why does owner dependence lower the value?

Because if the business "is" the owner (customers, processes, relationships tied to them), the buyer is purchasing a job, not a transferable company, and the multiple drops. A business that works without the daily owner is worth more. Paradoxically, the less it depends on you, the more it is worth.

Is the SDE value the sale price?

No, it is a starting point. The real price emerges from negotiation and depends on motivation, number of buyers, payment terms, what is included, due diligence and the market. Often a fixed part plus an earn-out is used. The valuation serves to set a credible range.

What data do I need?

Six: net profit, owner's compensation, personal benefits, one-off extraordinary expenses, depreciation and interest, and the SDE multiple. All add-backs must be legitimate and documentable to withstand the buyer's due diligence.

Does it work even if net profit is low or negative?

Yes. In many small businesses net profit is low because the owner pays themselves a lot: the add-backs (especially compensation) rebuild the real SDE. The calculator accepts even a negative net profit, as long as the sum with the add-backs gives a positive SDE.

Is it an official valuation?

No. It is an indicative estimate based on the SDE method, which depends on the accuracy of the data and add-backs and on the subjective choice of the multiple. For a formal valuation (sale, financing, dispute) turn to a professional (accountant, appraiser, broker).
