Question 1

What is book profit?

Accepted Answer

Book profit is what a book's royalties bring in, minus what it cost to make and sell: one-off costs like editing and the cover, and monthly costs like ads.

Question 2

How do you calculate book profit?

Accepted Answer

Book profit is your royalty per copy times the copies sold, minus your one-off costs and your monthly costs.

The book profit calculator works out the royalty per copy from each store's rules.

Question 3

Is printing a cost in the book profit calculator?

Accepted Answer

No, printing isn't a separate cost in the book profit calculator.

KDP takes the printing cost from each print royalty, so it's already in the royalty per copy.

Question 4

Do I need to buy an ISBN?

Accepted Answer

You don't need to buy an ISBN for KDP print books: KDP gives a free one, which works only on KDP. eBooks don't need an ISBN on KDP.

Question 5

What if my book never breaks even?

Accepted Answer

If your monthly ad spend is more than your monthly royalties, the book never breaks even at that pace, and the book profit calculator says so.

Lower the ads or raise the sales to find the point where it does.
