How it works
The flow should be simple enough to use quickly and structured enough to produce a useful publishing decision.
Step 1
Set the publishing model
Choose ebook, paperback, or both so the estimate reflects the formats you actually plan to sell.
Step 2
Add price and production costs
Use realistic editing, cover, formatting, and other costs instead of treating the launch as free.
Step 3
Adjust sales assumptions
Move the monthly sales and KU numbers until the projection looks plausible for your niche and backlist size.
Step 4
Review the earning path
Use the outputs to see break-even timing, monthly upside, and whether the publishing plan is financially coherent.

Use the income view alongside cost planning so pricing, investment, and launch expectations stay connected instead of drifting apart.
