Understanding your kdp ebook delivery fee calculation is essential for accurately forecasting net royalties on Amazon Kindle Direct Publishing. Amazon charges a digital file delivery fee—typically $0.15 per megabyte in the United States—only on ebooks enrolled in the 70% royalty option, deducting this cost directly from your list price before applying the royalty percentage. Authors who publish image-heavy manuscripts or fail to compress digital files can see significant margin erosion, making file size optimization a core publishing step.

According to Amazon KDP documentation, delivery fees are charged on the digital file size after conversion and apply exclusively to transactions under the 70% royalty option. The table below outlines standard delivery fee rates across major currencies, payout schedules, and eligibility requirements as of 2026.

How to Perform a KDP Ebook Delivery Fee Calculation
Calculating your exact net earnings per ebook sale requires running your final converted file size through Amazon’s delivery formula. Follow these steps to determine your exact payout per unit.
Step 1: Check Converted File Size in KDP Rights & Pricing
Upload your manuscript (EPUB or DOCX file) to the KDP Dashboard. Amazon converts the file into its proprietary format, which alters the final size. Navigate to the “Kindle eBook Pricing” page to view the exact converted file size rounded to two decimal places.
Step 2: Apply the Regional Megabyte Rate
Multiply the converted file size in MB by the per-megabyte delivery rate for the specific regional store where the sale occurs. For instance, a 3.2 MB converted file sold in the US market yields a delivery charge of 3.2 × $0.15 = $0.48.
Step 3: Subtract Delivery Fee from List Price and Calculate Royalty
Subtract the calculated delivery fee from your ebook’s list price to find the net royalty base. Multiply that net amount by 0.70. For a $4.99 ebook with a $0.48 delivery fee: ($4.99 – $0.48) × 0.70 = $3.16 net royalty per copy sold. To understand how print editions compare, consult our guide on KDP paperback printing cost calculation.
Step 4: Evaluate 35% vs 70% Royalty Options for Large Files
If your file size is very large (for example, 15 MB image-heavy textbooks or cookbooks), the delivery fee ($2.25) heavily reduces profits on low list prices. A $3.99 list price under 70% yields ($3.99 – $2.25) × 0.70 = $1.22. However, under the 35% tier with zero delivery fee, $3.99 × 0.35 = $1.40. In such cases, choosing 35% yields higher net revenue.

Payout Rules, Minimums, Delays, and Independent Contractor Taxes
KDP issues payouts approximately 60 days following the end of the calendar month in which sales occur. For example, royalties earned in January are paid at the end of March. Payments are disbursed via Direct Deposit (EFT), wire transfer, or check. Direct deposit has no minimum payout threshold in major marketplaces, whereas wire transfers and physical checks may carry a $100 minimum balance requirement before funds release.
For tax purposes, Amazon KDP reports earnings to US-based authors on Form 1099-MISC or Form 1099-NEC if net earnings exceed $60 in a calendar year. Self-published authors are treated as independent contractors and are responsible for paying federal, state, and self-employment taxes (Schedule C and Schedule SE). Tax obligations and income reporting requirements vary significantly in the UK, Canada, and Australia; authors in these jurisdictions should consult a certified tax professional regarding local reporting rules.

Red Flags, File Bloat Mistakes, and Account Risks
Unintended file bloat is one of the most common mistakes self-published authors make on KDP. Here are critical traps that erode royalties or trigger account flags:
- Uploading Uncompressed High-Res PNG Images: Inserting raw 300 DPI PNG graphics directly into Word manuscripts can inflate ebook sizes to 30 MB or higher. Always resize images to 1000–1200 pixels on the longest edge and compress them to JPEG format before embedding.
- Miscalculating File Size Before Upload: Your original DOCX or EPUB file size is not what Amazon charges for. Amazon converts your file, adding metadata and proprietary code that often expands the final size. Always rely on the size displayed on the KDP Pricing page.
- Price-Matching Penalties: Setting your ebook list price at $2.99 while pricing it cheaper or free on competitor platforms causes Amazon to automatically price-match your book. If the matched price drops below $2.99, Amazon shifts your royalty tier to 35%, eliminating 70% earnings entirely.
- Public Domain Content Restrictions: Attempting to claim 70% royalties on public domain or non-exclusive content violates KDP terms. Public domain books are restricted to the 35% option regardless of list price or file size.
Frequently Asked Questions
Does Amazon charge a delivery fee on KDP paperback or hardcover books?
No. Digital delivery fees apply exclusively to ebooks enrolled in the 70% royalty tier. Physical print books (paperback and hardcover) incur fixed and per-page print costs rather than megabyte-based delivery fees.
How can I check the delivery fee before publishing my ebook?
Once you upload your manuscript content in Step 2 of the KDP setup, proceed to Step 3 (“Kindle eBook Pricing”). KDP displays the exact converted file size and automatically calculates the delivery fee for each currency marketplace based on your entered list price.
What is the delivery fee rate for KDP ebooks in Canada and Australia?
As documented in Amazon KDP’s pricing terms, the delivery fee is $0.15 CAD per megabyte in the Canadian store and $0.21 AUD per megabyte in the Australian store for titles enrolled in the 70% royalty plan.
Is there a maximum delivery fee cap per ebook?
Amazon does not explicitly cap delivery fees per MB, but the delivery fee cannot exceed the total list price. However, if high file sizes make royalties unprofitable, authors can switch to the 35% royalty option, which waives delivery fees entirely.
Verdict: Who Should Optimize File Sizes and Next Steps
Understanding delivery fee math is vital for fiction authors, non-fiction writers with embedded diagrams, and digital publishers distributing work on Amazon. Text-focused novels (under 1 MB) incur minimal delivery fees ($0.10–$0.15) and benefit maximally from the 70% tier. Creators publishing photo books, illustrated children’s books, or heavy graphic manuals should perform strict image compression before uploading, or evaluate the 35% royalty option if file size exceeds 10 MB.
Your immediate next step is to log into your KDP account, navigate to your title’s “Kindle eBook Pricing” tab, review the converted MB file size, and verify that your list price yields optimal net profit margins across all regional marketplaces.
