Based on your inputs — conservative estimates used throughout
Estimates are illustrative and based on industry averages. Actual results vary. Published authors typically see speaking fees increase 2–5x and client conversion improve 30–60% post-publication.
• Speaking revenue = fee × engagements × 1.3 (book-effect multiplier based on industry surveys)
• Client revenue = new clients × deal value × 0.85 (conservative conversion rate)
• Book royalties = sales × avg. royalty ($4.50 self-pub, $2.80 traditional)
• Platform value = audience size × genre CPL × 5-year growth factor
