Hi @PurpleFogSound. Thanks for your question. As mentioned before, earnings will certainly differ based on individual authors, and a subscription model is a completely different product from a one-off purchase, so it is worthwhile understanding the dynamics of how it all works.
It’s designed as a new source of revenue that authors weren’t getting before, so these additional earnings are what help to generate an increase in overall earnings. I would encourage you to to look at Elements and think about the metrics that matter for a subscription (total monthly downloads, monthly earnings, average monthly earnings per item, etc.) and also reach out to other authors about their experiences. Video authors on Elements for example, have seen their earnings increase with Elements and you can read more about these experiences on the forums thread here.
