This guide explains how the Amazon Book Calculator works, the formulas used, practical examples, important publishing factors, and frequently asked questions to help authors make better financial decisions.
What Is an Amazon Book Calculator?
An Amazon Book Calculator is an online financial tool designed to estimate the income and profitability of selling books through Amazon.
When authors sell books on Amazon, the money earned is not equal to the listed selling price. Several costs affect the final earnings, including:
- Amazon royalty percentage
- Printing expenses
- Number of copies sold
- Book pricing strategy
- Distribution costs
The calculator simplifies these calculations by showing estimated earnings after applying the royalty percentage and subtracting printing costs.
For example, if your book sells for $15 and your royalty percentage is 40%, your royalty before printing costs would be calculated from that percentage. After subtracting the printing expense, the calculator shows your estimated profit per copy.

Royalty Per Book = Book Selling Price × (Royalty Percentage ÷ 100)
Example:
Book Price = $20
Royalty = 40%
Calculation:
20 × (40 ÷ 100)
= 20 × 0.40
= $8 royalty per book
2. Profit Per Book Formula
Profit Per Book = Royalty Per Book − Printing Cost
Example:
Royalty Per Book = $8
Printing Cost = $3
Calculation:
8 − 3
= $5 profit per book
3. Total Revenue Formula
Total Revenue = Selling Price × Number of Books Sold
Example:
Book Price = $20
Copies Sold = 500
Calculation:
20 × 500
= $10,000 total revenue
4. Total Printing Cost Formula
Total Printing Cost = Printing Cost Per Book × Number of Books Sold
Example:
Printing Cost = $3
Copies Sold = 500
Calculation:
3 × 500
= $1,500 printing cost
5. Total Profit Formula

Example:
Profit Per Book = $5
Copies Sold = 500
Calculation:
5 × 500
