Practical Example
Example 1: Kindle eBook
- Price: $4.99
- Royalty: 70%
Calculation:
- $4.99 × 70% = $3.49 per sale (approx.)
If you sell 200 copies/month:
- 200 × $3.49 = $698 monthly income
Example 2: Paperback Book
- Price: $12.99
- Printing Cost: $4.00
Calculation:
- Royalty = (12.99 × 60%) − 4.00
- = 7.79 − 4.00
- = $3.79 profit per sale
If you sell 150 copies:
- 150 × $3.79 = $568.50 monthly income
