A business with no physical assets is valued on the cash it can generate, not the things it owns. For service firms, consultancies, and software companies, that means learning how to value a business with no assets by applying one of four earnings- or revenue-based methods: Seller Discretionary Earnings, EBITDA, revenue multiples, or discounted cash flow. The IRS takes the same view. Revenue Ruling 59-60, the foundational framework for appraising closely held companies, lists earning capacity, financial condition, and goodwill among the factors an appraiser must weigh.
Which method fits depends on the size of the business, whether the owner is still running day-to-day operations, and how much of the story sits in past performance versus future growth. Most sales end up triangulating between two or three of them.
Start by Cleaning Up the Financials
Every method below runs on the same input: reliable historical earnings. Pull three to five years of federal tax returns and internal profit-and-loss statements. Sole proprietors report business income on Schedule C attached to Form 1040. S corporations file Form 1120-S and pass income through to shareholders on Schedule K-1.1Internal Revenue Service. S Corporations C corporations file Form 1120. The numbers on those returns should tie to your bank statements and bookkeeping ledgers before you show anything to a buyer.
Then identify the add-backs that reveal true earning power. Common ones include:
- Above-market owner compensation. If you pay yourself $250,000 but a hired manager would cost $120,000, the $130,000 difference is added back.
- Personal expenses run through the business, such as personal vehicle leases, travel, or insurance premiums that would not continue under new ownership.
- One-time costs like a lawsuit settlement, rebranding project, or office relocation that will not recur.
Each add-back needs documentation. A buyer’s due-diligence team, or a quality-of-earnings analyst on deals above roughly $1 million, will test every line. Unlike a standard audit that confirms past compliance, a quality-of-earnings analysis is forward-looking. It probes whether the earnings you claim are sustainable by examining revenue quality, customer concentration, working capital, and the reasonableness of each add-back. Preparing your records as if this report is inevitable strengthens your position at closing.
Seller Discretionary Earnings for Small Owner-Operated Businesses
Small businesses where one person runs the show are usually valued on Seller Discretionary Earnings. SDE equals net profit plus every financial benefit that flows to a single working owner: the add-backs above plus the owner’s full salary, benefits, and perks. It answers a straightforward question. How much cash would one full-time owner-operator take home each year?
Multiply the SDE by a factor that reflects risk and desirability. The multiplier scales with earnings size:
- SDE under $100,000: multipliers tend to fall between 1.2 and 2.4.
- SDE between $100,000 and $500,000: multipliers generally range from 2.0 to 3.0.
- SDE above $500,000: multipliers can reach 2.5 to 3.5 or higher.
A consulting firm with long-term contracts and low client turnover commands a higher multiplier than a freelance operation with unpredictable revenue. SDE assumes the buyer will step into the owner’s daily role, which is why it works for businesses where the owner is actively running things.
EBITDA for Businesses Beyond the Single-Owner Model
Once a company has real management structure and the owner is no longer doing every job, EBITDA (Earnings Before Interest, Taxes, Depreciation, and Amortization) becomes the better measure. It strips out financing costs, tax strategies, and non-cash accounting entries to isolate operating profitability. For asset-light companies, the depreciation and amortization add-backs are usually small since there is little equipment or property to write down.
Normalizing Adjustments
Reported EBITDA rarely tells the whole story for a private company. Normalizing adjustments restate the financials to reflect what a new owner would actually experience. They fall into three categories:
- Fair-market-value adjustments that replace above- or below-market owner compensation, related-party rent, or family-member salaries with figures an independent party would charge.
- Non-recurring items such as insurance recoveries, lawsuit settlements, restructuring costs, or windfall contracts that will not repeat.
- Pro-forma adjustments for known changes, like excluding revenue from a major client you already lost, or applying a current exchange rate to foreign-currency earnings.
The result is Adjusted EBITDA, and that number becomes the baseline for the multiplier.
What Multiples Look Like
Buyers apply an industry-specific multiple to Adjusted EBITDA. For private service companies, multiples vary with both industry and earnings size. Consulting businesses with $1–3 million in EBITDA often see multiples around 4 to 5 times earnings, while the same type of firm with $5–10 million in EBITDA may trade at 8 times or higher. Most private service-business sales close somewhere between 4 and 10 times Adjusted EBITDA, with recurring revenue, customer diversification, and growth trajectory driving where in that range you land. Public-company multiples run higher, but private transactions are discounted for illiquidity and size.
Revenue Multiples for High-Growth Software Businesses
Some companies, particularly software-as-a-service firms, are spending aggressively on growth and show little or no bottom-line profit. Valuing them on earnings would produce a misleadingly low number, so buyers use a multiple of annual revenue instead.
Private SaaS companies typically trade at 3 to 10 times annual recurring revenue. The multiple climbs with the growth rate. Companies growing above 40 percent annually often receive premium multiples in the 8 to 10 range, while those with low-teens growth and negative margins sit in the low-to-mid single digits. Investors generally expect valuations below 10 times revenue unless a growth rate of 50 percent or more looks clearly sustainable.2Crunchbase. SaaS Valuations Are Unshakable
The Rule of 40
One quick benchmark for software companies is the Rule of 40. Add the revenue growth rate to the free-cash-flow margin, and the sum should hit 40 percent or higher. A firm growing at 60 percent with a negative 15 percent cash-flow margin scores 45 and passes. A firm growing at 20 percent with a 10 percent margin scores 30, a warning sign. The single number weighs the tradeoff between growth and profitability and often predicts which companies receive premium multiples.
Discounted Cash Flow When Future Growth Is the Story
The discounted cash flow approach values a business on the cash it is expected to generate over a defined future period, adjusted for the time value of money. Instead of anchoring on last year’s earnings, DCF projects free cash flow forward, typically five to ten years, and discounts each year back to present value using a rate that reflects the risk of actually receiving that money.
The basic formula divides each year’s projected cash flow by one plus the discount rate, raised to the power of the year number. After the projection period, a terminal value captures the business’s worth beyond the forecast horizon, and that figure is also discounted back to today.
The discount rate is the most debated input. Larger companies use a weighted average cost of capital that blends equity and debt returns. Small private businesses carry a higher rate because their cash flows are less certain and the investment is harder to sell. A shift of even a few percentage points swings the final valuation dramatically, which is why DCF works best alongside the earnings-multiple and market-comparison methods rather than as a standalone answer.
DCF earns its keep when historical financials do not tell the full story. If you expect a sharp ramp in revenue over the next three years from a new product launch or a recently signed enterprise contract, DCF lets you model that trajectory into the price in a way that a backward-looking SDE or EBITDA multiple cannot.
Check the Market
After running internal calculations, test them against reality. The market comparison approach looks at what buyers have actually paid for similar businesses in recent transactions. Brokers and appraisers search private-transaction databases filtered by industry code and revenue bracket, aiming for three to five closed deals that resemble the subject company.
Adjusting these comparisons requires context. A deal that included seller financing, an earn-out, or an assumption of liabilities is not directly comparable to an all-cash offer. A business with higher-than-average margins leans toward the upper end of the observed range; one with concentrated revenue leans lower. The goal is a realistic price band that reflects what the current market will bear, not just what the math says.
The Illiquidity Discount
Private businesses are harder to sell than publicly traded stock, and buyers expect compensation for that. Appraisers apply a Discount for Lack of Marketability. IRS-reviewed studies place it anywhere from roughly 13 percent to 45 percent of the pre-discount value, depending on the size of the interest, availability of financial data, and expected holding period.3Internal Revenue Service.

Intangibles That Move the Multiplier
When a business has no physical assets to secure the price, intangible strengths and weaknesses drive the final multiplier up or down. Buyers assess these qualitative factors alongside the financial models.
Intellectual Property and Brand
Federal trademark registrations, copyrights, and proprietary technology create barriers competitors cannot easily replicate. A software company with patented algorithms, or a service firm with a nationally recognized brand, holds value that exists independently of the current owner. Long-term client contracts, especially those with assignability clauses allowing transfer to a new owner, add further certainty to future revenue.
Customer Concentration
If a single client accounts for more than about 15 percent of revenue, buyers begin flagging concentration risk. Above 25 to 30 percent from one client, most buyers reduce the multiple or restructure the deal to protect themselves, often by tying part of the price to an earn-out contingent on the client staying. A broad customer base is one of the most effective ways to protect valuation.
Key-Person Dependence
Asset-light businesses are especially vulnerable to key-person risk. If revenue depends on the founder’s personal relationships, technical skill, or public reputation, a significant portion of the value walks out the door when the founder leaves. Documented processes, a trained management team, and client relationships held at the company level reduce the risk. A formal key-person discount has historically been set around 10 percent of pre-discount value, though the practical impact on a sale price can be far larger if the buyer simply walks away.
Non-Compete Agreements
Buyers of service businesses almost always require the seller to sign a non-compete. It prevents the seller from starting or joining a competing business for a defined period, commonly two to five years, within a specified geographic area. A portion of the purchase price is allocated to that agreement on IRS Form 8594, and the allocated amount is taxed as ordinary income to the seller rather than as a capital gain.4Internal Revenue Service.

Bringing in a Professional
A certified business appraiser, typically holding a CVA (Certified Valuation Analyst) or ABV (Accredited in Business Valuation) credential, charges roughly $2,000 to $10,000 or more, depending on the complexity of the engagement and the level of reporting required. A calculation of value for internal planning costs less than a comprehensive appraisal prepared for tax compliance or litigation.
If your goal is a sale rather than internal planning, doing the math yourself with the methods above gives you a realistic price band and shows a buyer you know your numbers. A professional appraisal is worth the fee when the valuation has to hold up to outside scrutiny: an IRS filing, a divorce, a partner buyout, or a serious purchase offer where a written third-party opinion carries weight the seller’s spreadsheet cannot.
