The short answer: Jungle Scout's 2025 survey puts the average small/medium Amazon seller at $140,052 in annual sales and a 21% margin, about $29,412 a year in profit, closer to a side income. Owners of established, sellable stores doing $500K, $1M in revenue typically produce $75,000, $250,000 in SDE, since well-run e-commerce businesses convert roughly 15%, 25% of revenue into owner earnings. That SDE, not inventory, not top-line revenue, is what sets price, at roughly 3.33× SDE.
What e-commerce owners actually earn
"Owner pay" in a small e-commerce business is really two numbers stacked together: any salary or draw the owner takes, plus the profit the store throws off after that draw, ad spend, cost of goods, and fulfillment fees. Buyers and brokers combine them into seller's discretionary earnings (SDE), the total economic benefit to one owner-operator before financing. It's the number that matters when you're buying, because your loan payment comes out of it, and it's the number online brokers actually multiply to set price.
Jungle Scout's State of the Amazon Seller 2025 survey, nearly 1,500 sellers across 20+ countries, found small and medium Amazon sellers average $11,671 in monthly sales ($140,052/year) at a 21% profit margin, or about $2,451 a month ($29,412/year) in profit. A majority of sellers run margins above 10%, but only about a third clear 20%. That figure captures the whole population of Amazon sellers, including small, part-time, and early-stage stores, it's a useful margin benchmark, but it understates what an established, acquirable business earns, since most sellers at that revenue level aren't running a business anyone could buy and finance.
Owner earnings by revenue band
| Annual revenue | SDE @ 15% | SDE @ 25% | Profile |
|---|---|---|---|
| $250,000 | $37,500 | $62,500 | Solo Amazon FBA seller, 1 to 2 SKU lines |
| $500,000 | $75,000 | $125,000 | Established Shopify DTC brand, owner-run |
| $1,000,000 | $150,000 | $250,000 | Multi-channel brand, light staff/VA support |
| $2,500,000 | $375,000 | $625,000 | Multi-SKU brand, 3PL + small team |
These are illustrative bands using a 15%, 25% owner-margin range, which brackets Jungle Scout's ~21% average across all sellers. Actual SDE depends heavily on channel mix, ad spend as a percent of revenue, and product margin. Amazon-heavy stores tend to sit lower in the range once referral fees, FBA fees, and PPC spend are netted out; DTC brands with a strong email list and repeat-purchase rate can push toward the top.
The best-priced stores make money without a maxed-out ad account, the ad spend is a lever, not the whole engine.
Building SDE: the add-backs
When you underwrite a target, you rebuild SDE from the P&L and tax return. Legitimate add-backs in an e-commerce business typically include:
- Owner's salary / draw, added back, then a market replacement wage considered for someone to run ops, source suppliers, and manage ad accounts.
- Personal expenses run through the business, travel to trade shows or supplier visits, a vehicle, or family members on payroll who don't work.
- One-time costs, a Shopify re-platform, a rebrand, a one-off legal fee, or a product-launch cost that won't recur.
- Interest, depreciation, and non-cash items, removed to show operating cash flow, separate from how the current owner financed inventory or equipment.
Don't add back "one-time" ad spend spikes as savings
Some sellers cut ad spend right before a sale to inflate trailing profit. If ad spend as a percent of revenue dropped sharply in the months before listing, normalize it back to the historical average before you trust the SDE.
How earnings become a purchase price
Price follows SDE, plus inventory added on top. At the ~3.33× SDE anchor for e-commerce, the earnings bands above map to value like this:
| SDE | Business value @ 3.33× | ~10% SBA down |
|---|---|---|
| $75,000 | $249,750 | $24,975 |
| $150,000 | $499,500 | $49,950 |
| $300,000 | $999,000 | $99,900 |
Remember: this table is the business value only. Inventory on hand at closing is priced separately at landed cost and added to reach the total purchase price, see the full worked math on the cost-to-buy page.

Frequently asked questions
It varies enormously with size. Jungle Scout's State of the Amazon Seller 2025 report found small and medium Amazon sellers average about $140,052 in annual sales at a 21% profit margin, or roughly $29,412 a year in profit, a side-income level. Owners of established, sellable Shopify or Amazon brands doing $500,000 to $1,000,000 in revenue typically produce seller's discretionary earnings of roughly $75,000 to $250,000, since well-run stores commonly convert 15% to 25% of revenue into SDE.
Established, owner-operated e-commerce stores typically run a 15% to 25% owner margin measured as seller's discretionary earnings divided by revenue, above the roughly 21% average margin Jungle Scout found across all surveyed Amazon sellers. Margins compress with heavy ad spend and thin product margins, and expand with strong organic/repeat traffic and a healthy email list.
No. SDE reflects the operating profit of the business, but inventory on hand at closing is valued separately at landed cost and added to the purchase price on top of the SDE multiple. A buyer should never treat inventory value as part of the earnings stream being capitalized.
Price is usually SDE times a multiple of about 3.33x for a small, owner-operated store. A business with $150,000 of SDE would be worth roughly $499,500 at 3.33x, before adding inventory at cost. Multi-channel businesses with low customer concentration and a real email list push toward the top of the range.
