I would really like to see the option to set royalties higher than 50 percent.
Some of the products I create are priced so low in the marketplace that even at the full 50 percent royalty, there is no way to make them viable. After the Marketing Fee and other deductions, the actual earnings end up being much lower than what the calculator suggests.
That gap makes it really difficult to price things in a way that reflects the time and work involved. Designing is just one part of it. There is also uploading, fixing issues, and promoting, and many of us are bringing in our own traffic.
If we had the ability to go above 50 percent, it would simply give us more control to adjust pricing where it is needed. It would not force higher prices across the board, just give flexibility on products that are currently undervalued.
Right now, there are items where even the maximum royalty is not enough to make them worth continuing.
