How the math works

Kindle eBooks

Amazon pays 70% of list price for books priced $2.99–$9.99, minus a delivery fee of $0.15 per MB. Outside that window (like $0.99 or $12.99) you get 35% with no delivery fee.

royalty × list − (15¢ × MB) 70% tier
royalty × list 35% tier

Paperback & hardcover

Amazon pays 60% of list on its own store, minus the printing cost: $0.85 + $0.012 per page for a standard black-ink paperback (June 2023 US rates). Expanded distribution pays 40%.

60% × list − printing cost

Break-even

Your upfront costs (editing, cover, ads) divided by royalty per unit, rounded up. That's the number of copies before you've paid yourself back.

break-even units = upfront ÷ royalty

Worst case

Month-in, month-out revenue on your pessimistic unit guess. Plan your marketing on the worst column, celebrate on the best.

worst-case = pessimistic units × royalty
