This free book ROI calculator shows what a book is worth to your business.

It counts the royalties, and the readers who take your offer and become clients. Every rate is yours, so the answer is about your business, not a promise.

Here's what book ROI is, where your numbers come from, and how to raise it.

What is book ROI?

Book ROI is the return on what a book cost you: everything it brings in, minus the cost, divided by the cost.

For a business owner, most of that return often comes from clients, not royalties.

How the book ROI calculator works

It follows each reader through the book:

  1. Copies sold, times your royalty per copy
  2. Readers who take your offer: a checklist, a call, your list
  3. Of those, the ones who become clients
  4. Clients, times what a client is worth

The total, minus what the book cost, divided by the cost, is your ROI.

Where to get your numbers

Use your own numbers. The rates differ so much by offer and audience that anyone else's would mislead you.

  • Copies. Your sales reports, or a launch goal.
  • Readers who take your offer. Sign-ups from the link in your book, over copies sold.
  • Clients. How many of those leads bought, from your CRM.
  • Client value. What a client pays you over time.

Give the link in your book its own tag, so you can count it. The UTM builder makes one in a minute.

How to raise your book's ROI

The offer in the book matters more than its price.

  • Give something to take. A checklist or a template, linked where the reader needs it.
  • Link it more than once. In the chapters where it helps, not only at the end.
  • Make the next step clear. Say what happens after they sign up.

I do this with my own AI OS book: everyone who joins its list reads the first chapter before it goes on sale.
