Across the 13 Amazon businesses we have researched, the median estimated profit is $37,201 a month on about $89,989 of monthly revenue. The range is enormous: from $5,580 a month to $8.15 million. These are not average sellers, though. They are sellers visible enough to research, and that matters for every number below.
We cannot give you the average seller, because we do not see the ones who stopped. What we can give is the spread among established, visible sellers, using the latest month in our data (September 2026, August for OTOTO):
Ten of the 13 earn under $100,000 a month in estimated profit. All figures are modelled estimates, not accounts.
| Monthly revenue | Businesses | Est. monthly profit |
|---|---|---|
| Under $60K | Wet Noses, Bizzikins, Restoration Games, Mount Cleverest, LIGHTEN LIFE, Highmark Collective | $5.6K to $20.1K |
| $60K to $250K | Spite House Games, KALOTOYS, Virora Mahjong, OTOTO | $37.2K to $91.8K |
| Over $250K | Kajun Loaded Tea, White Mountain Puzzles, MaryRuth's | $221.9K to $8.15M |
Margins in that table run from 24.1% to 54.2%. A bigger business is not automatically a more profitable one: KALOTOYS makes $156,692 a month but keeps 31.5%, because advertising takes about 16.5% of its revenue.

Monthly profit swings with the season. Spite House Games' revenue was $349,150 in December 2025 against $96,959 in August 2026. White Mountain Puzzles' Amazon US revenue was $1.53 million in December 2025 and $246,072 in May 2026. A single month is a poor guide to a year. OTOTO shows the opposite risk: its January to August 2026 sales ran 45% below the same months of 2025.
These profit figures are before tax, owner pay and overhead. They also depend on Amazon's cut, which is a large part of the story; see how much Amazon takes from sellers, and for startup cost see how much Amazon FBA costs to start.
WaitHowMuch publishes revenue and profit for real businesses. Unless a profile says otherwise, the figures are estimates built from public information — not the company's accounts. Every profile shows how its numbers were reached.
