Valuation: Revenue vs SDE vs EBITDA for Solo Founders

Ask on the blended midpoint, not any single method: for a solo business at $250k revenue, $80k SDE, and $50k EBITDA, the three methods span $225,000 (EBITDA) to $500,000 (revenue), and the defensible asking number is the $321,667 blend. Leading with one base alienates two-thirds of the buyer pool, because each base anchors a different buyer mindset. This article compares the three methods on a single scenario, names which buyer category each method attracts, and recommends the blended approach that survives every type of due diligence.

1. Three bases, three buyer mindsets

The three valuation bases differ in what they measure.

Revenue measures top-line traction. A revenue multiple values a business based on the size of its customer base and the growth rate, regardless of profitability. Anchored by strategic acquirers, aggregators, and growth-stage VCs who care about market share and trajectory more than current cash flow.

SDE (Seller's Discretionary Earnings) measures cash flow to the owner-operator. SDE = operating profit + owner's salary + owner's benefits + discretionary expenses. Anchored by operator-buyers who plan to run the business themselves and care about the cash they can extract.

EBITDA (Earnings Before Interest, Taxes, Depreciation, Amortization) measures pure operating profit, with no add-backs for ownership. Anchored by financial buyers, holding companies, and roll-up acquirers who care about cash-on-cash return at scale.

The NYU Stern sector multiples database^[1] publishes industry-level multiples for all three. Software/internet at public-company scale trades at roughly 6x revenue and 25x EBITDA; small-business multiples are materially lower, with SDE multiples 2.5x to 4x being typical.

2. Same business, three valuations

Scenario inputs: annual revenue $250,000, SDE $80,000 (32% SDE margin, typical for a one-person SaaS), EBITDA $50,000 (20% EBITDA margin, lower because EBITDA excludes the owner's salary add-back), 20% annual growth rate. Multiples: 2.0x revenue, 3.0x SDE, 4.5x EBITDA.

The Revenue Multiple is 2.0x × $250,000 = $500,000 mid ($375k to $625k range). The SDE Multiple is 3.0x × $80,000 = $240,000 mid ($192k to $288k). The EBITDA Multiple is 4.5x × $50,000 = $225,000 mid ($180k to $270k). The blended midpoint is $321,667, with a blended range of $249,000 to $394,333.

The three method outputs differ by 2.2x at the high end ($500k vs $225k). The blended midpoint of $321,667 is the honest asking number — it does not alienate any of the three buyer categories and gives all three a path to feeling the price is fair from their preferred lens.

3. Revenue multiple: when it wins, when it lies

Revenue multiples win when the business is high-growth (20%+ annually) or pre-profitable (negative EBITDA, positive growth). Acquire.com's marketplace data^[4] shows SaaS businesses sold at 2x to 5x revenue, with the spread driven by growth rate (10% growth maps to 2x, 100% growth maps to 5x+).

Revenue multiples lie when the business is mature, profitable, and owner-operated. A 2x revenue valuation on a $250k revenue business says the business is worth $500k regardless of whether it makes $80k SDE or $5k SDE. A buyer running SDE math will value the high-SDE version at $240k and the low-SDE version at $15k. The revenue multiple compresses this 16x difference into a single number, which is misleading.

Use revenue multiples when:

• Growth rate is above 20% annually
• Customer base is large enough that strategic value matters (acquirer can monetize the base via cross-sell or upsell)
• Recurring revenue is dominant (subscription, contracted)
• Buyer is a strategic acquirer or aggregator, not an operator

Avoid revenue multiples when:

• Growth rate is under 10% annually
• Revenue is one-time or transactional (not recurring)
• Business is owner-operated and the owner is leaving (the customer relationships may not transfer)
• Buyer is an operator looking for cash flow

4. SDE multiple: the solo-founder default

SDE multiples are the standard for owner-operated businesses under $5M revenue. The IBBA Pulse Report Q4 2024^[2] reports median SDE multiples of 2.5x to 3.5x for service businesses, 3x to 4x for software and digital businesses, and 2x to 3x for retail and physical products. BizBuySell's Q4 2024 Insight Report^[3] shows similar distributions on a larger sample.

The SDE calculation matters. SDE = operating profit + owner salary + owner benefits (health insurance, retirement contributions) + discretionary expenses (personal vehicle, business meals beyond legitimate business need, unusual one-time costs). For a solo founder paying themselves $40k/year and running the business through their personal expenses, SDE is materially higher than the P&L's bottom line.

The defensible SDE calculation is documented and auditable. A buyer's due diligence will verify the add-backs; aggressive add-backs that fail audit reduce the buyer's offer or kill the deal. The right practice is to document add-backs in a separate workbook with receipts and explanations, ready for due diligence.

SDE multiples are anchored by operator-buyers — people buying the business to run it. Their math: SDE is what they can extract from the business as personal income. A 3x SDE multiple means three years of payback at current SDE, plus growth upside. The one-person SaaS valuation article walks through the SDE-anchored sale process.

5. EBITDA multiple: when scale and structure matter

EBITDA multiples are the right lens for businesses with management structures (not owner-operators), businesses over $5M revenue, or businesses sold to financial buyers who will install professional management. Empire Flippers' 2024 marketplace data^[6] shows EBITDA multiples of 3x to 6x for established digital businesses, with the spread driven by recurring-revenue percentage and team structure.

The advantage of EBITDA over SDE: EBITDA is comparable across buyer types because it strips out ownership-specific factors. A financial buyer running their own management does not get the SDE add-backs (owner salary, owner benefits, discretionary expenses); they only get the operating profit. EBITDA is the right base for that buyer.

The disadvantage: EBITDA is materially lower than SDE for owner-operated businesses, which lowers the valuation. A $250k revenue / $80k SDE / $50k EBITDA business sold to a financial buyer at 4.5x EBITDA values at $225k. The same business sold to an operator at 3x SDE values at $240k. The $15k gap is the cost of switching buyer type.

For solo founders, EBITDA-multiple framing is appropriate only when targeting financial-buyer or aggregator-buyer pools. For sales to other solo operators, SDE is the right base.

6. Why the blended estimate is the honest asking number

The blended midpoint of $321,667 is the asking number that works across buyer types. Three reasons.

It anchors fairly. For this example, the blended midpoint sits within roughly 35-45% of each buyer's preferred valuation: a 36% discount to the revenue-anchored buyer's $500k, a 34% premium over the SDE-anchored buyer's $240k, and a 43% premium over the EBITDA-anchored buyer's $225k. Revenue-anchored buyer ($500k preferred) sees $321,667 as a discount and may pay close to ask. SDE-anchored buyer ($240k preferred) sees $321,667 as a premium and negotiates down toward $270k-$290k. EBITDA-anchored buyer ($225k preferred) sees $321,667 as well above their math and walks unless there is a strategic reason to pay above EBITDA logic.

It produces deal velocity. A listing priced at the blended midpoint tends to close faster than one priced at the highest single-method valuation, because the blended price does not require the buyer to accept the seller's preferred framing. The deal can close at any of the three frames; the price just needs to map to one of them at the buyer's preferred multiple.

It survives due diligence. Aggressive single-method valuations (revenue multiple on a low-growth business, SDE multiple with implausible add-backs) fail buyer due diligence and force the seller to renegotiate down or kill the deal. Blended valuations are inherently more defensible because they incorporate multiple lenses.

The methodology behind the engine's blended-range calculation is documented at the Business Valuation Calculator methodology page^[5].

7. Each method anchors a different buyer pool

Selling a business is also selling to a specific buyer pool. The valuation framing pre-selects the pool.

• Revenue-multiple framing attracts strategic acquirers, growth-stage aggregators, SaaS holding companies. They pay above-SDE because they monetize the asset differently than the seller does (cross-sell, upsell, integration into a larger product). Listings: Acquire.com (SaaS), MicroAcquire, Tiny.
• SDE-multiple framing attracts operator-buyers and small-business investors. They pay based on cash they can extract. Listings: BizBuySell, IBBA broker network, FE International (for service businesses), local broker networks.
• EBITDA-multiple framing attracts private equity, search funds, and small-buyout firms. They pay based on cash flow at scale and the multiple-expansion thesis (buy at 4x, scale, sell at 7x). Listings: search-fund networks, regional PE, lower-middle-market brokers.

Solo founders selling under $1M valuation almost always end up with operator-buyers (SDE framing). Above $1M, the mix expands. Above $5M, EBITDA and revenue framings start to dominate. The framing should match the realistic buyer pool, not the seller's preferred number.

8. Which method to lead with by business profile

Decision rule:

• Pre-profit SaaS with 20%+ growth, revenue under $500k: lead with revenue multiple. SDE is small or negative; EBITDA is irrelevant.
• Profitable owner-operated SaaS under $1M revenue: lead with SDE multiple. Blended with revenue multiple for upside framing.
• Profitable owner-operated service business: lead with SDE multiple. Revenue multiple does not apply; EBITDA is too aggressive.
• Profitable team-operated business $1M to $5M revenue: lead with blended estimate. All three methods are relevant.
• Over $5M revenue with management structure: lead with EBITDA multiple. Revenue and SDE are secondary frames.
• Strategic acquisition candidate (vendor, complement, ecosystem): lead with revenue multiple regardless of size. Strategic buyers think in revenue terms.

Frequently asked questions

Which valuation method should a solo founder use: revenue, SDE, or EBITDA?

All three, blended. Buyers use different methods depending on their thesis; presenting only the highest leaves the negotiation anchored at the lowest. For a $250k revenue business with $80k SDE and $50k EBITDA, the engine returns $500k revenue value, $240k SDE value, $225k EBITDA value, blended midpoint $321,667.

Why does the revenue multiple value the business so much higher?

Revenue multiples are highest because they ignore profitability. For high-growth or pre-profit businesses (most early-stage SaaS), revenue multiples are appropriate. For owner-operated profitable businesses, revenue multiples are aspirational; SDE or EBITDA multiples are more defensible. The 2x revenue multiple gives $500k; the 3x SDE multiple gives $240k.

What is the difference between SDE and EBITDA?

SDE (Seller's Discretionary Earnings) adds back the owner's salary, benefits, and discretionary expenses to operating profit. EBITDA does not. For an owner-operator drawing $50k in salary plus $10k in personal-business overlap expenses, SDE is materially higher than EBITDA, and SDE multiples are designed to reflect that.

Which method do small-business buyers actually use?

SDE for businesses under $5M revenue, per IBBA and BizBuySell data. EBITDA for businesses over $5M revenue or with management teams (not owner-operators). Revenue multiples for high-growth SaaS regardless of size. Software-specific marketplaces like Acquire.com use both revenue and SDE multiples; physical businesses on BizBuySell are dominantly SDE.
