How ebook royalties are estimated
For 35%, royalty = 0.35 × (list price − applicable tax). For 70%, royalty = 0.70 × (list price − applicable tax − delivery cost). Enter the tax amount that applies to this sale; a zero default is a no-tax scenario, not an automatic tax determination.
Worked US example: a $4.99 ebook, 1 MB converted file and $0 applicable tax gives a $0.15 delivery cost. 0.70 × ($4.99 − $0.15) = $3.388, displayed as $3.39 per sale. At 100 sales, the unrounded estimate totals $338.80. This assumes all 70% conditions are met.
How paperback royalties are estimated
Royalty = marketplace rate × KDP list price − printing cost. The US rate is 50% below $9.99 and 60% at or above $9.99. UK uses £7.99, euro marketplaces €9.99, Canada and Australia 13.99 in local currency, and Japan ¥1,000. Amazon.in paperback distribution is unsupported.
Worked example: a US 250-page black-ink, regular-trim paperback has an official printing-cost example of $1.00 + 250 × $0.012 = $4.00. At a $15 list price, royalty is $9.00 − $4.00 = $5.00. Do not reuse that printing cost for a different trim, color, paper or marketplace; enter your own official cost.
Why we ask for your printing cost
Amazon’s printing tables vary by marketplace, trim size, ink and page count, with fixed-cost exceptions for shorter books. A single global per-page average can mislead authors. This calculator deliberately asks for the official cost instead of silently guessing it.
Estimated monthly sales are your scenario, not our demand forecast. Compare several prices, but consider readers, comparable books, returns and advertising costs before deciding what to charge.
