KDP Paperback/Hardcover Royalty & Sales Calculator

Calculate your scenario

Formulas and assumptions

Printing cost and royalty rate come from KDP's published tables for your book type, trim size, interior, page count, and marketplace. The sales estimate comes from your Best Sellers Rank; advertising cost comes from your conversion rate, CPC, and the share of sales you assume are organic versus ad-driven.

• Royalty rate is 60%, or 50% below the marketplace's royalty-rate price threshold.
• Your royalty (per book) = (list price, minus VAT where applicable) × royalty rate − printing cost.
• Break-even ACoS = royalty per book ÷ list price.
• Est. monthly sales uses a BSR-to-daily-sales curve, multiplied by 30 and by a marketplace sales multiplier relative to Amazon.com.
• Clicks per sale = 100 ÷ conversion rate. Cost per sale = clicks per sale × CPC.
• Net monthly profit/loss = estimated monthly royalty − estimated monthly ad cost (ad cost applies only to the ad-attributed share of sales).

This is a scenario calculator, not a sales forecast or a tax calculation. The BSR-based sales estimate is a rough curve fit, not a guarantee of actual sales, and does not account for seasonality, category, or promotions. Returns, withholding, and other marketplace deductions are not modeled beyond the printing cost and royalty rate tables.

Printing-cost tables and the BSR sales curve are ported from the owner's standalone KDP calculator; the Amazon.se royalty threshold was corrected to 110 SEK (KDP's current published value) and VAT is now extracted from the tax-inclusive list price rather than subtracted as a flat percentage of it. Use the launch guide to plan cash reserves and testing allowances.

Where to find your royalty

This calculator estimates printing cost and royalty from KDP's published rate tables for the book type, trim size, interior, page count, and marketplace you select. KDP's paperback royalty guidance explains how the applicable rate and printing costs are determined; check it for the current official figures if you need to confirm an edge case.

Best Sellers Rank changes constantly and the sales estimate is a rough curve fit, not a reported number from Amazon. Use it for relative scenario planning, not as a guaranteed sales figure.

For interpretation, read ACoS versus royalties and profit and what to check when clicks do not convert. Adigy automates routine advertising optimization around your goals; these calculations help you choose goals that fit the book's economics.
