How Much Is a Business Worth With $500,000 in Revenue?

The first thing a seller tells you is revenue. "It's a half-million-dollar business." It sounds like a fact. It functions like a headline.

Revenue is the easiest number to say and the least useful for setting a price. Two businesses can each book $500,000 a year and be worth amounts that differ by a factor of five. One is a lean service business where the owner takes home $180,000 after expenses. The other is a storefront that grosses the same but bleeds rent, payroll, and COGS, leaving the owner $35,000 and a sixty-hour week. Same revenue. Not remotely the same business.

So when someone asks "how much is a business worth with $500,000 in revenue?", the honest answer starts with a correction: that's not how Main Street businesses are priced. They're priced on what's left — and on how confident a buyer can be that what's left will still be there next year without the current owner standing in the middle of it.

Revenue is a vanity number. SDE is the real one.

For owner-operated businesses under roughly $5 million in value — services, trades, retail, food, light manufacturing — the standard valuation metric is seller's discretionary earnings (SDE), not revenue and not net income as reported.

SDE answers a specific question: if I buy this business and run it myself, how much money does it actually put in my pocket before debt service and taxes? That means starting from net income on the tax return and adding back the things that exist only because of the current owner:

• Owner compensation — salary, draws, and health insurance for one working owner.
• Discretionary personal expenses — the car, the phone, the "business" travel that's really personal.
• Non-cash charges — depreciation and amortization.
• Documented one-time items — a lawsuit settlement, a one-off equipment write-off.

The formula is short:

SDE = Net Income + Owner Compensation + Discretionary Expenses + Non-Cash Charges + One-Time Items

If you want the mechanics — every add-back category, what counts and what doesn't — that's its own subject, covered in detail in how to calculate SDE and what SDE actually is. For valuation, the point is simpler: SDE is the engine. Revenue is just the chassis. A big chassis with a weak engine doesn't go anywhere.

This is also where the most common manipulation lives. Because SDE is built from add-backs, and add-backs are judgment calls, a motivated seller (or broker) can inflate the number that the entire price is built on. I've written separately about how brokers inflate SDE — the short version is that every aggressive add-back, multiplied by the multiple, becomes real dollars on the purchase price. A $40,000 phantom add-back at a 3x multiple is $120,000 of price built on air.

The formula: SDE × multiple

Once you have a defensible SDE, valuation is mechanically simple:

Business Value = SDE × Multiple

The multiple is where the real work is. For most Main Street SMBs, it lands between 2x and 4x SDE, and the bulk cluster between 2.0x and 3.0x. The multiple is a measure of confidence — how sure a buyer is that the earnings are real, durable, and transferable to someone who isn't the current owner.

A clean way to think about it: the multiple is the market's answer to "how many years of earnings am I willing to pay up front to own this?" At 3x, you're paying three years of current profit to buy the next however-many years. The buyer who pays 3x is betting the earnings hold. The buyer who pays 2x is hedging against the possibility they won't.

That's why two businesses with the same SDE can carry different multiples — and why a serious buyer never accepts a multiple without interrogating what's underneath it. For the deeper version of that interrogation, see what makes a fair price for a business and when a 3x multiple is actually expensive.

Worked example #1: $500,000 in revenue, two outcomes

Take two businesses, each with exactly $500,000 in annual revenue.

Business A: a lean services firm

A small commercial landscaping company. The owner runs the crews, handles sales, and does the books at night.

At a market multiple for a stable, recurring-contract services business with a documented book of clients, call it 2.75x:

$180,000 × 2.75 = ~$495,000

So this $500,000-revenue business is worth roughly $495,000 — close to a 1x revenue coincidence, but arrived at entirely through earnings.

Business B: a retail storefront

Same $500,000 in revenue. A specialty retail shop with a lease, three part-time employees, and inventory.

Here's the catch most first-time buyers miss: this owner works full-time in the store and the $52,000 SDE includes the value of that labor. A buyer who would have to hire a manager at $45,000 to replace the owner is really looking at $7,000 in transferable profit. The business barely supports a buyer who isn't willing to stand behind the counter sixty hours a week.

At a generous 2x on the raw SDE: $52,000 × 2 = ~$104,000. Adjust for the owner-labor reality and a careful buyer values it far lower — or walks. This is the owner-dependence trap: you're not buying a business, you're buying a job with a lease attached.

Same $500,000 revenue. Business A is worth roughly $495,000. Business B is worth roughly $100,000 — and arguably much less. That five-to-one spread is the entire reason "how much is a business worth with $500,000 in revenue?" has no single answer.

Worked example #2: $100,000 in revenue

The smaller the business, the more extreme this gets. A business with $100,000 in revenue is almost always a one-person operation, and its value is driven entirely by how much of that top line survives to the owner's pocket — and whether it survives the owner leaving.

Say a solo bookkeeping practice books $100,000 in revenue with very low costs:

On paper, $92,000 SDE looks great — a 92% margin. But almost all of that is the owner's own labor and the owner's own client relationships. The transferable multiple on a business this owner-dependent is low — frequently 1x to 2x, sometimes a fraction of that — because the moment the owner leaves, the clients may follow. So $92,000 SDE might command $90,000–$150,000, not the $250,000+ the margin alone would imply.

And a different $100,000-revenue business — one where costs and the owner's labor consume nearly all of it — can have an SDE near zero and a transferable value near zero. You'd be paying for the idea of a business that doesn't generate independent profit. The honest valuation is "buy the assets, if anything, and don't pay for goodwill."

The lesson holds at every size: revenue sets the ceiling on what's possible; earnings and durability set the price.

What actually moves the multiple

Two businesses with identical SDE can sell at 2x and 4x. The difference is risk and durability. Here's what pushes the multiple in each direction — and roughly what each factor is worth.

Pushes the multiple UP:

• Recurring or contracted revenue — subscriptions, service contracts, repeat customers. Predictability is the single most valuable trait.
• Low owner dependence — a business that runs with a manager and documented systems is worth materially more than one that lives in the owner's head.
• Diversified customers — no single customer over ~10–15% of revenue. (The opposite — customer concentration — is one of the fastest ways to lose a turn on the multiple.)
• Clean, verifiable financials — tax returns that tie to bank statements, with add-backs you can document.
• Growth trend — three years of rising SDE earns a premium over flat or declining.

Pushes the multiple DOWN:

• Customer concentration — one client at 40% of revenue can cut the multiple in half.
• Heavy owner involvement — the Business B problem above.
• Declining earnings — buyers price the trend, not the peak year.
• Regulatory or licensing exposure — see regulatory and licensing red flags.
• Messy or unverifiable books — every dollar a buyer can't verify is a dollar they assume is zero.

A practical heuristic: start at a baseline of ~2.5x for an average owner-operated business, then add or subtract quarter-turns for each factor above. A business with recurring revenue, a manager in place, and clean books might genuinely earn 3.75x. A business with one big customer, an indispensable owner, and a soft trend earns 2x — and you should be relieved to get it that low.

The number that closes the deal: financeable value

There's a final layer that catches buyers who do everything else right. The price a seller will accept and the price a deal will finance are two different numbers — and for most acquisitions under $5M, financing means an SBA 7(a) loan.

The lender doesn't value the business on the seller's SDE. The lender re-derives a conservative, normalized SDE, often averaging two to three years rather than using the best one, and then checks whether the resulting cash flow can cover debt service with margin to spare. That margin is the debt-service coverage ratio (DSCR), and most SBA lenders want it at 1.25x or higher. (The mechanics are in how to calculate DSCR for SMB acquisitions and what DSCR SBA lenders actually require.)

Here's why it matters for valuation: if a seller's $180,000 SDE gets normalized down to $150,000 by the lender, the maximum price the deal can carry at a 1.25x DSCR drops accordingly — sometimes by tens of thousands of dollars. You can agree on a price with the seller and still have the bank tell you the cash flow won't support it. At that point the real value of the business is whatever a 1.25x DSCR allows, regardless of the multiple you negotiated. Working that backward — from financeable cash flow to maximum offer — is exactly what how to calculate maximum offer price covers.

So the full chain is: revenue → SDE → multiple → asking price → financeable price. Most buyers stop at one of the first two links. The deal is decided at the last one.

What I'm still working out

The part of this I find genuinely hard isn't the formula — it's the multiple, because there's no published table that's actually right for a specific business. Brokers cite "industry multiples" with a confidence the data doesn't support. The comps that exist are thin, self-reported, and survivor-biased toward deals that closed. Two appraisers can look at the same business and disagree by a full turn.

What I keep coming back to is that the multiple isn't really a market fact — it's a confidence interval on the durability of the earnings, and reasonable people price confidence differently. A buyer who can replace the owner cheaply sees less risk than one who can't. That makes the "right" multiple partly a function of the buyer, not just the business.

If you've bought or sold in a specific industry, I'd genuinely like to know: how much does the multiple actually vary deal-to-deal once you control for size and recurring revenue? My working assumption is "more than the broker tables admit." I'm not sure I'm right.
