Writing, teaching and digital products
You make it once and sell it many times, or you sell your words by the job. Here are the real royalties, wages and platform fees.

Platforms publish their fees. What they cannot tell you is how many copies you will sell. Make the sum with your own price, then be honest about how you will find buyers.

The catch
- Publishing is not selling. No platform promises you buyers.
- Udemy’s and Substack’s own pages could not be read when we checked, so their numbers rest on independent sources that agree.
- Platform fees are only part of the cost. Your time to make the product comes first.
- Check whether a low plan’s transaction fee costs more than a higher plan with none.
