The two published routes
Gumroad's pricing page lists direct/profile transactions at 10% plus $0.50 and transactions from new customers through Discover at 30%, checked October 8, 2026. For a $10 order, that stated charge is $1.50 on the direct route and $3 on Discover. The difference is $1.50. These are comparisons of the published rates, not a claim that every applicable cost is included.
Do not call the fee difference free traffic
The higher marketplace charge should be considered alongside how the customer arrived. A shopper who would have followed your link anyway is different from an additional shopper you would never have reached. Eligibility for a discovery surface, visibility and actual purchases are separate questions. Neither listing a product nor paying a larger fee guarantees buyers.
Compare your own acquisition costs
Suppose you spend $30 on an experiment and obtain ten additional completed direct orders. Acquisition cost is $3 per order, before the platform charge. At a $10 price, the example direct platform charge plus that acquisition cost would be $4.50 per order. This is arithmetic with assumed results, not an argument for buying ads. Organic promotion also costs time, even if it has no cash ad spend.
A useful crossover calculation
For the stated rates, Discover minus direct is 0.20 × price − $0.50. At $10 that is $1.50; at $20 it is $3.50. A positive result is the extra stated marketplace charge before other differences. The two rates meet at $2.50 in this limited calculation. This mathematical threshold does not establish equivalent services or a platform recommendation.
Measure the route, not just the revenue
Record attributable completed orders, refunds, fees and any acquisition spend. Keep existing customers separate from newly acquired ones where possible. Compare net results over a normal period, not only your best launch day. The cheaper route per order may produce fewer orders, while the route with more revenue may keep less cash.
