Earnings disclaimer

Last updated November 2, 2026

Numbermill is a tool for making workbooks. Buying it does not mean you will sell any books or earn any money.

We make no claims about how much you may earn. What you earn depends on your own work, the books you choose to make, your listings, your prices, marketplace rules and fees, competition and demand, none of which we control.

The “What you earn on Amazon” panel in the app shows Amazon KDP's published printing cost and royalty per copy for a list price you type. It is a calculation for one copy sold, not a forecast of sales. Amazon can change its tables at any time; check them on KDP before you set your prices.

Nothing on these pages is financial, legal or tax advice. Results other people have had are not typical and are not a promise of your results.
