The full sample for this category, most-rated first. Rating count is a floor on units sold, not a sales figure — only some buyers rate, and that share differs by category. Use it to rank listings against each other, never to estimate revenue.

Method
What this sample is. These are the 44 listings Gumroad ranked first in Education > Science when the category was crawled on 5 August 2026, up to three pages deep. It is not a count of everything in the category, and nothing here supports a claim about category size — 191 of the 261 categories came back at the same 44-listing crawl cap. What it does support is comparison: every category was sampled the same way, from the same ranking, on the same day. Prices are converted to USD at ECB reference rates for 2026-08-06.
The data behind this page
This page is generated from a free, openly licensed dataset of 8,322 distinct
Gumroad products across 261 of Gumroad's own categories, with the seller
recorded for every one —
data/gumroad-taxonomy.csv,
the collector and
the normaliser are all
public. CC BY 4.0, no signup, no email wall.

- What to charge on Gumroad Why this category's median is a starting point rather than an answer: across the whole market price and demand turn out to be close to unrelated.
- What to sell Which categories show demand and which are mostly unsold inventory, ranked by the same rated-share figure quoted at the top of this page.
- All 261 categories, ranked The same figures for every category Gumroad publishes, in one table.
What is not free is the analysis: which categories are openings versus crowded rooms, where price and demand come apart, and what the background rate of unsold listings means if you are choosing what to build next. You are paying for the interpretation, not for the rows. The rows are free, above and in the repository. If the data is all you wanted, take it and skip this.
