How to Value an Online Business

How to Value an Online Business

Until September 8, 2026, Empire Flippers listed businesses as a multiple of monthly profit. It now uses yearly profit, so a site that would have shown 36x appears as 3.0x at the same asking price. Accountants, traditional brokers and BizBuySell were already working in annual figures.

Mixing up which profit number the multiple applies to does more damage than the units. Take the cookware store used as the example further down. Three times its net profit is about $341,000, and three times its SDE is about $588,000. If the seller means one and the buyer hears the other, they start about $247,000 apart.

The short version

  • An online business is priced as earnings times a multiple. Getting the earnings figure right matters more than arguing over the multiple.
  • For small, owner-run businesses the earnings figure is usually seller's discretionary earnings (SDE): profit with the owner's pay, personal perks and one-off costs added back.
  • Empire Flippers now reports annual multiples. Its typical listings average about 2.3x a year's profit, with distressed businesses near 1.1x and seven-figure premium businesses around 3.4x.
  • Across 2,117 US small businesses sold in the second quarter of 2026, BizBuySell recorded an average of 2.7 times cash flow.
  • Ecommerce deals usually add stock on hand at cost on top of the multiple.
  • Earnouts, holdbacks and seller financing change what you actually receive at closing, so compare offers on cash at close, not headline price.

The formula, and the three earnings figures people confuse

Price is earnings times a multiple. Three different earnings figures get plugged into that sum, and for the same business they can be tens of thousands of dollars apart.

Earnings figure What it is Who tends to use it
Net profit Revenue minus every expense on the profit and loss statement, owner's pay included if it's on payroll Marketplaces and brokers for smaller sites, often with the owner's pay excluded
SDE (seller's discretionary earnings) Net profit with the owner's salary, personal perks, one-off costs, interest, depreciation and amortization added back Most brokers for owner-run businesses up to a few million in value
EBITDA Earnings before interest, tax, depreciation and amortization, with a market-rate salary for management still deducted Larger businesses, private equity and anything with a real management team

The same store can produce three very different numbers. The store in the example below shows about $114,000 of net profit, $196,000 of SDE, and roughly $160,000 of adjusted EBITDA once the owner's pay is swapped for a market-rate manager's salary. If you're comparing an offer to a published multiple, check which figure that multiple was applied to. Otherwise you're comparing a 2.7 that means one thing with a 2.7 that means another.

Working out SDE, line by line

SDE starts from your profit and loss statement and adds back anything a new owner wouldn't have to pay. The rule a buyer will apply is simple enough. If the cost keeps the business running, it stays in. If it exists because of you personally, or it won't happen again, it can come out.

Here's a made-up example. It's a Shopify and Amazon store selling cast-iron care products: seasoning oil, chain-mail scrubbers, pan handle covers. The figures are its last 12 months.

Line Amount
Revenue $640,000
Cost of goods sold −$224,000
Ad spend (Meta and Amazon) −$128,000
Shipping and fulfillment −$70,400
Apps and software −$9,600
Freelance designer −$12,000
Owner's salary on payroll −$60,000
Owner's car lease, run through the business −$7,200
One-off legal fees for a trademark dispute −$9,000
Depreciation and amortization −$2,400
Interest on a business loan −$3,600
Net profit $113,800

Now the add-backs. The owner's $60,000 salary goes back in, since a buyer will decide for themselves how to pay whoever runs the place. So does the $7,200 car lease, which is a personal perk. The $9,000 trademark fight is a one-off, provided there's paperwork showing it's settled. Depreciation and amortization ($2,400) don't involve cash leaving the account, and the loan interest ($3,600) stays with the seller, because the loan doesn't transfer.

That's $82,200 of add-backs, which brings SDE to $196,000.

Waterfall chart from $113,800 net profit to $196,000 SDE and $160,000 adjusted SDE

What a buyer won't accept as an add-back

Sellers stretch this part, and buyers know it. Here's how buyers tend to treat the common ones:

Usually accepted Usually rejected
Owner's salary and payroll taxes "We'd cut ad spend if we had to"
Personal car, phone, travel with no business purpose Ad spend you paused for two months to make profit look better
One-off legal, setup or migration costs, with invoices Costs that happen "once" every year
Interest on loans that don't transfer Freelancers you plan to stop paying
Depreciation and amortization Revenue you expect from a product that hasn't launched

Everything in the right-hand column is a decision that hasn't been made yet, and the seller wants paying for it now. Buyers pay for last year's numbers, with receipts.

The owner's time still costs something

Our cast-iron store's owner works about 25 hours a week on it: answering customer emails, reordering stock, managing the ad accounts, approving designs. Adding back the full salary assumes none of that work needs doing after the sale. It does. A buyer will estimate what it would cost to hire someone for those hours. Say a part-time operations manager at $36,000 a year.

Take that off the $196,000 of SDE and the figure a buyer actually multiplies is closer to $160,000. That's the adjusted EBITDA figure from the table above; some brokers call it adjusted SDE. The more hours the business needs from you, the bigger the deduction, which goes a long way to explaining why hands-off businesses sell for more.

Monthly multiples, annual multiples, and the data behind them

For most of the last decade, Empire Flippers and many online business guides quoted monthly multiples. A site making $5,000 a month and selling for $150,000 went for "30x". Traditional business brokers, accountants and private equity buyers have always used annual multiples, so the same deal was "2.5x" to them.

When Empire Flippers made the switch, it also converted the average listing multiples from its 2026 State of the Industry Report into annual terms. These are multiples on listings, not final sale prices, so treat them as a guide to where asking prices sit.

Empire Flippers category Old monthly multiple Annual multiple
Distressed businesses 13.7x 1.1x
Typical businesses 27.8x 2.3x
Premium businesses 31.1x 2.6x
Seven-figure premium businesses 41x 3.4x

To convert any monthly multiple you find in an older listing or article, divide it by 12.

Empire Flippers average listing multiples shown as annual figures, from 1.1x distressed to 3.4x seven-figure premium

For comparison, BizBuySell's Insight Report for the second quarter of 2026 tracked 2,117 US small business sales, mostly offline ones like restaurants, services and shops. The average cash flow multiple was 2.7, and the median business sold for $349,250 on median cash flow of $155,921. BizBuySell's "cash flow" works much like SDE, so it's a fair yardstick for a profitable online business with an owner doing real work in it.

The gap between "distressed" and "typical" in Empire Flippers' data is worth noticing. Distressed businesses are listed at roughly half the multiple of typical ones, and selling under pressure, because of a deadline, a partner dispute or a falling business, pushes you toward that end. On a business clearing $100,000 a year, that's the difference between about $230,000 and $110,000.

Putting a number on the example

Back to the cast-iron store, with $160,000 of adjusted SDE.

At Empire Flippers' typical listing multiple of 2.3x, the business itself is worth about $368,000. If it qualified as premium, with steady growth, clean books and little owner time, 2.6x would put it at $416,000.

Ecommerce has one more piece. Stock on hand is usually paid for separately, at cost or wholesale value, on top of the multiple. Empire Flippers has described its formula this way for years. If the store is holding $38,000 of seasoning oil and scrubbers at cost, the total comes to roughly $406,000 at the typical multiple, or $454,000 at the premium one.

Valuation of the example store: $406,000 at a 2.3x multiple or $454,000 at 2.6x, including $38,000 of inventory

A seller who'd multiplied the original $196,000 of SDE by 3 would have been expecting $588,000 plus stock. That figure isn't impossible, but it assumes the owner's 25 hours a week are free and that the business deserves a top-tier multiple, and a buyer will challenge both.

What moves the multiple

The multiple is the buyer's view of risk. Lower risk and stronger growth push it up; anything that makes next year's profit less certain pulls it down. These are the factors buyers weigh most often.

Factor Higher multiple Lower multiple
History Three or more years of clean records Under 12 months of profit data
Trend Revenue and profit rising over the last year Flat, falling, or one strong quarter propping up the average
Owner time A few hours a week, with documented processes The owner runs operations, ads and support personally
Traffic sources Several channels, including email and direct Nearly all traffic from one Google ranking or one ad platform
Platform risk Own store, own customer list Most revenue through one Amazon account or one app store
Customer concentration No customer above a few percent of revenue One client or wholesale account is 30% or more
Margins Healthy margin after ad spend, stable for a year Profit that depends on ad costs staying low
Recurring revenue (SaaS, memberships) Low churn, annual plans High monthly churn, mostly monthly plans
Supplier position Contracts that transfer, a backup supplier A single supplier and an informal arrangement
Size Seven figures and above, which attracts more buyers Small deals that only individual buyers will look at

Dependence on one platform

Content sites that rank well in Google are exposed to core updates. Amazon sellers live with account health and policy changes. Apps depend on Apple and Google's store rules. None of that rules out a sale, but a buyer will look at the last two or three years to see how the business handled the last shock. A site that lost 40% of its traffic in one update and hasn't recovered will be priced on today's numbers with a discount on top.

Ad-funded growth

Plenty of healthy stores spend around 20% of revenue on Meta and Amazon ads, and the cookware store is one of them, at $128,000 on $640,000. A buyer will pull a year of ad account history and set it next to the monthly margins. In this case, cost per purchase on Meta jumped in the fourth quarter, margin slipped by two points, and it had recovered by February. A buyer would read that as a store that can absorb rising ad costs, and price it accordingly.

Recurring revenue

For software and membership businesses, buyers look at churn before almost anything else. A SaaS product losing 2% of customers a month keeps most of its revenue through a year. One losing 8% a month is replacing most of its customer base annually, and it'll be priced like it. Smaller SaaS deals are often discussed as a multiple of annual recurring revenue as well as profit, so expect both numbers to come up.

How deal structure changes the number

Here are two offers for the cast-iron store. Both say $400,000 at the top of the letter.

Offer A Offer B
Cash at closing $400,000 $250,000
Seller financing None $100,000, paid over two years
Earnout None $50,000 if revenue holds for 12 months
Money you're sure of on day one $400,000 $250,000

Acquire.com's 2025 annual report on small SaaS deals found that buyers were adding more conditions: holdbacks in 14% of the deals it analyzed, seller financing in 13%, and other conditions across 41%. Expect similar terms in other online business sales, where buyers face the same traffic and platform risks.

Compare offers on how much you receive at closing, how much depends on things you no longer control, and what happens if the buyer struggles after taking over. A slightly lower all-cash offer is often worth more than a higher one with a large earnout. Sellers outside the US should also check how earnouts are taxed before agreeing to one. Our guide to selling an online business from outside the US covers the 30% US tax that can apply to performance-based payments.

Mistakes that cost sellers money

A common one is pausing ad spend for a couple of months before listing so profit looks higher. It shows up straight away in the monthly figures, and the buyer then starts doubting everything else in the spreadsheet too.

Personal spending is another. Running your phone, car and family trips through the business is fine for SDE, but only if there's a record of each one. "About $8,000 a year of personal stuff" won't get added back.

Some sellers lead with their best six months. Buyers ask for twelve regardless, and once they see the weaker half they tend to assume there's more you haven't shown them.

Borrowing a multiple from a different kind of business causes long, pointless negotiations. A SaaS revenue multiple applied to an affiliate site, for instance, sets an expectation far above what buyers will pay.

And the expensive one: waiting until profit has already started to fall. In Empire Flippers' numbers, distressed businesses are listed at about half the multiple of typical ones.

Five valuation mistakes that lower the price of an online business

Valuing specific types of business

The method above works for most online businesses, but some models have their own details.

What buyers check first for YouTube channels, ecommerce stores, content sites and SaaS businesses

YouTube channels follow the same method, with extra weight on whether one person is the face of the channel and on YouTube's content policies. We go through that in how much a YouTube channel is worth.

With Amazon and Shopify stores, expect questions about supplier terms, ad efficiency and stock levels, and remember the inventory is priced separately.

A content or affiliate site gets judged mostly on its traffic history. Buyers will pull up its search visibility through each Google core update of the last two years and check how much income depends on a single affiliate program.

For SaaS and membership products, churn comes first, then how much of the code, hosting and support the founder still handles personally.

Whatever the model, a buyer will check every number before closing. Our online business due diligence checklist goes through what they ask for.

FAQ

What multiple will my online business sell for?

Most profitable online businesses with a year or more of clean records sell for about 2 to 3 times annual profit, which is 24x to 36x monthly. Empire Flippers' typical listings average 2.3x annually. Businesses that are shrinking, very new or heavily owner-run go lower, and large, growing businesses with little owner involvement go higher.

Should I use SDE or net profit?

Use whichever figure the buyer or broker you're talking to uses, and say which one you mean. For a small business you run yourself, SDE is standard. Just remember that a buyer will deduct the cost of replacing your time.

Is my owner's salary deducted from the valuation?

Usually it's added back to calculate SDE. But if the business needs your hours to run, a buyer will subtract what it would cost to hire someone to do that work, so the salary doesn't vanish completely.

Do I get paid for my inventory separately?

For ecommerce businesses, usually yes. Stock on hand is normally valued at cost and added to the price, so count it carefully before you list.

How many months of data do buyers want?

Twelve months is the norm, and the 12-month average is what most multiples are applied to. Six months can work for a young business, but expect a lower multiple. Two or three years of history helps a lot, especially if the business came through a Google update or an ad-cost spike in that time.

Does revenue matter, or only profit?

Profit sets the price for most online businesses. Revenue matters mainly for SaaS, where buyers often look at annual recurring revenue, and as context for margins. A store with $2 million in revenue and $60,000 in profit is a thin-margin business, and it'll be valued on the $60,000.
