Four calculators I built for my own work, because the numbers vendors quote are rarely the numbers that matter. They run entirely in your browser — nothing is sent anywhere, nothing is stored, no signup.
KDP Royalty Calculator
What you actually keep per book, after printing and delivery fees. eBook and paperback.
Affiliate Commission Calculator
Turn a price and commission rate into revenue per 1,000 visitors, so you can compare offers honestly.
Faceless Channel Earnings Estimator
Ad revenue by niche and view count, and how many views $5,000 a month actually needs.
Software Launch Cost Calculator
What a launch product costs once the upsells are added, versus the advertised price.
Why these exist
Each one answers a question that gets answered badly everywhere else. “How much will I earn per book?” gets a percentage instead of a number. “Which affiliate offer is better?” gets compared on commission rate instead of revenue per visitor. “How much does this launch cost?” gets the front-end price instead of the real total.
