Formula Used in KDP Profit Calculation
This calculator uses standard publishing formulas used by Amazon KDP authors.
1. Royalty Earnings Formula
Royalty Earnings=100Book Price×Royalty Rate
This formula calculates how much Amazon pays you per sale before deducting costs.

Profit=Royalty Earnings−Printing Cost
This shows your actual earnings after subtracting production expenses.
3. Revenue Formula

Revenue represents total customer payment before deductions.
Example Calculation
Let’s understand with a real-world example:
Book Details:
- Book Price = $12.99
- Royalty Rate = 70%
- Printing Cost = $3.50
Step 1: Calculate Royalty
Royalty = 12.99 × 70 / 100
Royalty = $9.09
Step 2: Calculate Profit
Profit = 9.09 − 3.50
Profit = $5.59 per sale
Step 3: Revenue
Revenue = $12.99
Final Result:
- Royalty Earnings: $9.09
- Profit per Sale: $5.59
- Total Revenue: $12.99
