Hi @DaniyaImam16That is a good question. The short answer is no. You do not need to pay anything to Udemy in advance or after to publish, market, and host your courses on the platform. However, there is a revenue split between Udemy and you for each sale. The revenue can vary between sales. You can earn 97%, 50%, or 25% of the sale, here you can have detailed information of the revenue share. In other words, Udemy will earn only if you earn.
