Hi, Diandra! Welcome to the Cooler.
There are a number of ways to answer your question, so perhaps you could tell us what SORT of publishing you had in mind. See, there are different kinds, sort of like grocery shopping. You can:
a) go with one of the major companies like Random House, Dell, Tor or Avon (for example) where the royalties will be around 8-10% of the list price, and you'll receive an advance against future royalties; or
b) go with a small press/university press (depending on your book's genre/category) if the book really isn't of national interest but would sell really well in a geographic location or to fans of a hobby or interest. They pay a little higher commission because they often have a lower print run and less marketing of the book. Think in the 10-15% of list price range; or
c) go with an electronic publisher (you'll have to choose carefully. Some are really good, others not so much.) They often pay on NET price, rather than list price, though. So while you might see royalties on their website upwards of 25%, it's determine after expenses are paid by the publisher (something the larger companies don't do); or
d) finally, you can go with a self-publishing company or create your own company. While it's not a good way to make a LIVING as a writer, it can be useful to get just one book on the market. There are any number of companies that do this, but you'll pay THEM for the privilege of publishing, rather than them paying YOU. It should work the other way around, and you'll find yourself doing a lot of marketing of the book, rather than writing the next one. But if it's the only one, it's not a terrible thing. Most of the self-publishing companies use digital presses, and you'll see the term "print on demand" or "POD" used a lot. You'll also hear the terms "subsidy press" and "vanity press" in the same sentence. Subsidy means you're paying the publisher directly out of your pocket, rather than the sales of the book paying them.
Which one do you have in mind? Then we can direct you further.
