How we calculate

Amazon KDP Royalties

Amazon pays 35% royalty on most print/ebook combinations at market prices. High-volume sellers can qualify for 70% on ebooks priced $2.99–$9.99.

Consulting Rate Premium

Studies of independent consultants show published authors charge 20–40% more for equivalent work. We use a conservative 25% applied to your selected hours.

Speaking Fee Increase

Published authors report a 50–100% increase in speaking fees within 12 months of publication. We model 50% conservatively, applied to your current events cadence.
