Doctor Jupiter — Revenue
Researched profile. The figures here are modelled by us from public information, published with the sources they were drawn from. How we research.
Revenue
Christmas is most of the year. Each December sells more than the one before, and the January after it falls to between a sixth and a ninth of it, then build slowly through a birthday-present year to October. About a third of every month is kept, after Amazon’s two fees, the cost to make the kits, an assumed tariff, freight and modelled advertising — and Amazon’s pick-and-pack fee takes more of a sale than making the kit does.
The series counts every listing on the storefront and three bundles off it that carried a badge in past months, each at its own month-end price. A badge is a floor: the half of the catalogue without one counts as zero.

“Sold / mo” is Amazon’s own badge, a band, hence n+. Revenue is that band times each listing’s price at the month’s end, so every row is a floor. Of the 92 listings, 40 carried a badge; the 18 largest are itemised and the other 22, mostly gift sets and small kits, are one remainder. The rest count as zero.
Revenue is a floor and profit is a ceiling. The cost to make under the profit is Alibaba listing prices, three of the four resting on a single listing, and the tariff assumes the kits are made in China, which their listings do not say.
