Hey dragon_emma245,
Fair question! The FAQ here has more details about the program itself, but I've quoted the specific information related to your question as well.
What is the revenue share?
Makers take home approximately 30% of the Moola from their Pack sales. That means for every 100 Moola someone spends on their content, they earn 30 cents USD.
The Sims is covering all costs and fees associated with publishing, including overhead costs such as platform fees, VAT taxes, server costs, and other transactional expenses, which may vary by platform.
In addition to covering the publishing fees, The Sims’ reinvests in the Maker community, supporting Makers, improving tools and resources available to them, funding human-led quality verification, as well as ensuring every Maker Pack is translated into all 18 supported languages.
Hope that helps clarify how this is broken down!
