Fiction and nonfiction book sales are like horses and zebras. They look kind of alike, and their related in their DNA, but they ain’t nothin’ alike.
I don’t bother trying to sell my nonfiction. It should be an enticement to something bigger. Let’s say you self-publish a nonfic ebook and make $15 every time you sell a copy. You sell 1,000 and you’ll get $15k. BTW, unless you’re a name, you’re not going to sell 1,000 copies at a price that will net you $15 each.
