How the calculation works
Net sale revenue = copies sold × price × (1 − marketplace fee %)
Example
Selling 2,000 copies at $9.99 with a 30% fee produces about $13,986 before taxes and other costs.
Why this result matters
Gross sales can overstate the amount available to fund development. This model separates the marketplace share before other business expenses.
Tips for a more useful estimate
- Use the fee for the actual storefront and tier.
- Model discounts separately.
- Account for refunds, taxes, and regional pricing outside this estimate.
