Calculateur gratuit
de redevances pour les livres brochés KDP

This KDP royalty calculator answers one pricing question: for a supported US paperback, how much estimated royalty remains from one direct Amazon sale after printing cost? Use the tax exclusive list price entered in KDP. The retailer's displayed discount, customer shipping charge or your desired take home income is not the input to this formula.

Scope matters before arithmetic. This version is limited to Amazon.com, USD, 6 × 9 inch paperback, black ink, white or cream paper, and Amazon direct sales. A different marketplace, trim, distribution channel or printing option needs a different calculation. The cream maximum is 776 production pages; the white maximum is 828. An odd manuscript page count rounds upward to the next even production count.

Costs use unrounded values internally. For 334 pages, printing cost is $1 + 334 × $0.012 = $5.008. The interface displays $5.01, but subtracts $5.008 when calculating royalty. It rounds the print cost display and royalty display separately, using half away from zero for ties. Reusing the displayed cost can change a result by one cent.

The 110 page boundary needs special care: the published help table overlaps there. This model follows the $2.32 official calculator readback recorded October 13, 2026, rather than silently treating both help rows as consistent. Compare that boundary with the current official calculator. A calculated negative royalty is also useful information: it flags a price below modeled printing break-even, not a promise that KDP will accept that price.

Begin with the final interior PDF and count every file page, including unnumbered sections. Enter that manuscript count, then inspect the normalized production count. A 333 page manuscript becomes 334 production pages, so using 333 in a separate spreadsheet would not reproduce this tool. Choose white or cream according to the interior printing option, not the appearance of your cover artwork.

Next, confirm that your title is a 6 × 9 inch black ink paperback for Amazon.com direct sales. This tool does not offer a market selector that converts currencies or estimates other printing tiers. If the book is outside the stated scope, use KDP's calculator with the complete settings. Do not keep an unsupported estimate merely because the entered price looks plausible.

Enter the tax exclusive USD list price with at most two decimal places. The input range is $0.01 to $250.00; that validation range does not mean every price is publishable for every title. Read the printing cost, selected rate, estimated royalty and break-even together. A warning below break-even means the model's print cost exceeds the percentage of list price available to cover it.

For a controlled comparison, keep pages and paper fixed while changing only the price. Compare $9.98 with $9.99 explicitly because the rate changes at that boundary. Then try a price appropriate to the intended audience and product. Arithmetic can show the difference in royalty per copy; it cannot tell you whether customers will buy at the higher price or whether a competing edition changes demand.

Before saving the publishing price, match the current official calculator and the Rights & Pricing screen. Record the date, production pages, list price and source of the estimate beside your budget. A share link reproduces a setup for a collaborator; its query inputs accompany the web request and may appear in server logs. Calculation runs locally in the browser. Do not put account information, orders or unpublished financial notes into a shared URL.

The following values are formula examples for the supported US settings, not actual earnings or a quote for another market. Each count is an even production count. Raw printing cost is shown with three decimal places so the 334 page rounding example remains reproducible. The two royalty columns are rounded independently to cents after subtracting that raw cost.

The last row is within the white paper page limit but above the cream limit. Negative values demonstrate the formula at an inadequate price; they are not available selling offers. The 110 page row follows this tool's disclosed calculator readback and should be checked against the current KDP setup because the help table overlaps. Neither restriction disappears when a value is copied into a spreadsheet.

A one cent price increase across the threshold changes both price and rate. It is therefore wrong to describe the difference as one cent of extra royalty or to apply 60 percent to every candidate price. Use the table to check a pricing worksheet, then calculate your own production count rather than selecting the nearest example. For a different distribution channel or trim, replace the underlying model using official settings instead of adjusting these numbers by an assumed percentage.

A 300 page paperback book at the rate boundary

Assume 300 production pages, black ink on white paper and the supported trim. Print cost is $1 + 300 × $0.012 = $4.60. At $9.98, the 50 percent share is $4.99, leaving $0.39. At $9.99, the 60 percent share is $5.994, leaving $1.394, displayed as $1.39. The displayed difference is $1.00 per copy. This comparison holds the book constant; it is not a forecast of total income. At $9.20, the 50 percent share exactly covers $4.60, giving the modeled break-even price.

A longer book that crosses into the higher band

Assume 400 production pages with the same settings. Cost is $1 + 400 × $0.012 = $5.80. Dividing by 0.50 gives $11.60, outside the 50 percent price band, so that is not the applicable break-even candidate. Dividing by 0.60 gives $9.666666…, below the start of the 60 percent band. The first qualifying cent price is therefore $9.99, with $5.994 − $5.80 = $0.194, displayed as $0.19. Both band conditions matter; a single division does not solve this piecewise rule.

An odd manuscript and independent rounding

Assume 333 manuscript pages and a $9.99 price. Normalize to 334, then calculate $5.008 printing cost. Royalty is $5.994 − $5.008 = $0.986, displayed as $0.99. Subtracting the displayed $5.01 cost instead would give $0.984 and round to $0.98. The one cent mismatch comes from premature rounding rather than a different royalty rate. Retain the production count and raw cost when auditing a spreadsheet. These examples describe model arithmetic; no sale, advertising campaign or payment is assumed in any of the three cases.

Do not subtract the printing cost twice. The royalty shown here already includes that deduction; removing it again from estimated royalties understates the amount. Conversely, do not call the royalty total profit. Advertising, professional services, taxes and other business expenses are outside this calculation. Add those to a separate budget using your own actual records rather than an invented standard cost.

Keep the marketplace visible whenever discussing a number with a collaborator. A USD result for Amazon.com does not become a UK estimate by exchanging dollars for pounds. Also distinguish a paperback royalty estimate from ebook pricing and Merch on Demand estimates, which use different rules. A familiar brand name does not make the formulas interchangeable.

When a result differs from KDP, compare the book settings, production pages, channel and unrounded arithmetic before changing prices. Pay particular attention to the disclosed 110 page ambiguity. Use actual reporting after publication to evaluate business outcomes. The estimate supplies a per copy scenario, not evidence of demand, an earnings guarantee or a reason to assume the maximum supported price is a sensible selling price.
