Kobo Book Sales Trends: 50% Growth on PublishDrive in 2025 — Here's What Independent Authors and Publishers Should Know

If you're an independent author wondering whether Kobo deserves a place in your publishing strategy, the 2025 data on Kobo self-publishing trends answers that question decisively. Kobo book sales through PublishDrive grew 50% in sales value year over year — and the subscription channel, Kobo Plus, surged 158%. For self-published authors going wide, Kobo now ranks as the fourth-largest revenue channel on PublishDrive, behind only Amazon, Apple Books, and Google Play Books. These aren't marginal gains; they represent a meaningful, sustained shift in where independent publishing revenue is flowing. If you're evaluating wide distribution strategies or exploring how to self-publish on Kobo, this report explains what the numbers mean, which markets and genres are driving growth, and exactly how to increase Kobo sales and maximize your royalties in 2025.

Kobo Writing Life vs. PublishDrive: Why Kobo Self-Publishing Trends in 2025 Matter for Independent Authors Tracking Ebook Revenue

Kobo self-publishing trends in 2025 signal a major shift for independent publishers going wide. Kobo book sales — spanning both Kobo retail and Kobo Plus — are now the fourth-largest revenue channel on PublishDrive. Kobo book sales value posted 50% year-over-year growth in ebooks. What makes this particularly significant is that the growth is broad-based: it spans multiple genres, territories, and both the retail and subscription channels simultaneously. For independent authors tracking where ebook revenue is accelerating, this is one of the clearest signals in the 2025 data.

Whether you're researching how to sell books on Kobo, looking for the best ebook aggregators for Kobo, exploring Kobo self-publishing tips, or tracking where ebook revenue is growing fastest in 2025 — this data has direct implications for your publishing strategy. Beyond the headline numbers, the breakdown by market, genre, and channel reveals exactly where the opportunities are concentrated. Here's what the numbers actually mean, and what to do with them.

Self-Publishing Wide Distribution: What the PublishDrive Data Reveals About Kobo Sales Growth in 2025

PublishDrive's Market Intelligence Report 2026 aggregates transactional data across our global distribution network. Within this dataset, Kobo's 2025 performance stands out as one of the strongest growth signals across any single retail channel. What makes these numbers particularly compelling is the divergence between value and volume growth — a pattern that repeats across both the retail and subscription segments and suggests that independent authors are not just selling more books on Kobo, but earning more per book sold.

Here are the headline numbers:

Combined, Kobo and Kobo Plus rank as the fourth-largest revenue channel on PublishDrive in 2025, behind Amazon, Apple Books, and Google Play Books. That positions Kobo as a top-tier revenue source — not a niche or secondary channel. To understand how to capitalize on this ranking within a full multi-channel strategy, see our overview of PublishDrive platform features.

What these numbers do not indicate:

• Kobo's total revenue growth
• The ebook industry's overall growth
• Books distributed via Kobo Writing Life or competing aggregators

Kobo Writing Life vs. PublishDrive: How 2025 Kobo Self-Publishing Trends Compare to Broader Market Performance

To contextualize the PublishDrive-specific data, here's what Kobo's parent company, Rakuten Group, has publicly reported. The key signals across four consecutive quarterly disclosures are summarized below. Taken together, the corporate-level signals reinforce the directional momentum visible within PublishDrive's dataset — and help confirm that the Kobo self-publishing trends observed here are part of a broader, platform-level growth story rather than a statistical anomaly within one distribution network.

Rakuten Kobo — Corporate Performance Signals (Publicly Reported)

What Rakuten's filings confirm at a high level:

• Kobo's parent company reported consistent revenue growth across all four quarters reviewed.
• Growth was driven by both new color e-reader hardware launched in 2024 and expanding content and subscription sales.
• Rakuten confirmed the ebook market is continuously expanding and that Kobo's registered user base is steadily growing.
• Kobo was specifically cited as a key driver of international revenue and profit growth in multiple earnings calls.

Quarter-by-Quarter Highlights from Rakuten's Disclosures

• FY2024 (full year): Rakuten's International business unit, which includes Kobo, achieved revenue of USD 2,037 million, up 8.5% YoY, driven by strong earnings from Rakuten Kobo and Rakuten Viber.
• Q1 FY2025: Rakuten Kobo led International growth thanks to strong sales of color e-readers launched in Q2 last year.
• Q3 FY2025: The e-book market continues to expand. Rakuten Kobo has grown steadily on strong content and hardware sales. Rakuten cited Kobo as a driver of international revenue and profit growth, powered by strong performance in Rakuten Kobo's device and content sales.

Important Caveat on Comparing Rakuten and PublishDrive Data

Rakuten's disclosures do not isolate specific ebook growth percentages for Kobo. The qualitative signals are consistent across reports, but direct numerical comparisons to PublishDrive's dataset are not possible based on available public data. What the corporate disclosures do confirm is that Kobo's underlying business — hardware, subscribers, and content revenue — is growing across multiple dimensions simultaneously.

PublishDrive's transactional data is directionally aligned with these broader signals. What PublishDrive's platform data adds is granularity — the kind of channel-level detail that informs concrete publishing decisions:

• Which formats are performing
• Which countries are growing fastest
• Which genres are trending
• How the subscription channel performs relative to retail

Rakuten also confirmed in its Q3 FY2025 earnings call that the e-book market is continuously expanding. Within this expanding market, Kobo's total registered users have been steadily increasing. They specifically flagged that the color devices launched in April last year have been a long-running hit, driving growth in content sales and the number of subscribers.

⚠️ Comparison Caveat

The +50% and +158% figures should not be read as Kobo-wide growth rates. They reflect a specific cohort — publishers distributing wide through PublishDrive. Catalog dynamics (new title enrollments, format expansion, Kobo Plus opt-ins) may inflate the growth signal relative to Kobo's total business.

How to Increase Kobo Sales: Understanding the Two Revenue Streams Shaping 2025 Kobo Self-Publishing Trends

Self-publishing on Kobo operates across two distinct revenue streams: à la carte retail sales and Kobo Plus subscription. Each has a different growth profile, and understanding both is critical for any independent author learning how to increase Kobo sales and promote books on Kobo effectively.

Kobo Retail Performance: How +50% Value Growth Signals Better Monetization Per Book

Kobo Retail (+50% value, +21% volume):

The retail channel posted strong gains — and the gap between value and volume growth is especially worth noting. Rather than simply selling more books at lower prices, PublishDrive publishers appear to be generating higher revenue per transaction. This pattern suggests that pricing discipline and catalog maturity are contributing as much as raw volume growth to the overall revenue story. Specifically:

• Value growth significantly outpaced volume growth.
• Suggests improving monetization — likely higher average prices or stronger ebook pricing discipline.
• Reflects PublishDrive publishers' catalog behavior on Kobo — not Kobo's overall retail monetization dynamics.

Kobo Plus Subscription Performance: Why +158% Growth Is the Defining Kobo Self-Publishing Trend of 2025

Kobo Plus Subscription (+158% value, +98% volume):

The subscription channel tells an even more compelling story. Both dimensions surged — and as with retail, value outpaced volume, pointing to deeper reader engagement and stronger per-read returns as the catalog matures. For independent authors evaluating how to increase Kobo sales without requiring exclusivity, Kobo Plus represents the single most actionable lever in the current data:

• Both dimensions surged for PublishDrive publishers.
• Value still led volume, indicating more revenue per read as catalog engagement deepens.
• Reflects PublishDrive publishers' Kobo Plus performance only — not Kobo Plus's total revenue.

What PublishDrive Publishers Actually Earn on Kobo: Royalty Benchmarks for Self-Publishers

Zooming in on the royalty side of the equation, the per-unit averages across PublishDrive's 2025 distribution network provide a useful baseline for independent authors calibrating their revenue expectations. These figures reflect mean payouts across all genres, territories, and price points — so individual results will vary significantly, but the benchmarks offer a concrete starting point for evaluating whether Kobo belongs in your publishing strategy.

An important note on the Kobo Plus figure: the $2.20 average is a network-level mean across PublishDrive's publisher cohort and is not a guaranteed flat rate. Kobo Plus payouts are drawn from a variable revenue pool and are calculated based on minutes read — meaning faster readers generate lower payouts per "read" and slower readers generate higher ones. Kobo also reports reading activity in 300-minute increments, which affects how completed "reads" appear in your dashboard compared to Amazon's KENP per-page model. Standard industry estimates for a 300-page equivalent novel on Kobo Plus typically range from $0.95 to $1.50 depending on reading speed. Use the $2.20 figure as a directional benchmark, not a per-title projection.

These averages reflect all PublishDrive publishers, all genres, and all Kobo territories. Use them as baseline calibration — not individual title projections. A premium non-fiction title at $19.99 will generate a much higher per-sale royalty than a $2.99 genre fiction title. That variability is precisely why tracking performance by channel, genre, and territory — rather than relying on platform-wide averages — is essential for any serious effort to increase Kobo sales over time.

The $5.00 average audiobook royalty on Kobo Plus is a particularly notable data point. It's more than double the ebook subscription royalty — reflecting higher production costs and pricing structures that flow through to per-listen returns. For authors who have already produced audiobooks, enrolling them in Kobo Plus represents one of the most straightforward ways to increase royalties without additional production investment.

Geographic Breakdown: Which Markets Are Driving Self-Publishing Wide Distribution Growth and How to Increase Kobo Sales by Territory in 2025

Kobo's geographic footprint within PublishDrive's data is heavily concentrated in Canada, Northern Europe, and select Asia-Pacific territories. For independent authors researching how to distribute ebooks globally, these markets represent significant untapped opportunity — especially for those exploring how to promote books on Kobo in non-US markets. 

One of the most important insights from the geographic data is that every single tracked Kobo market grew year over year in 2025. This is not a story of a single breakout territory masking weakness elsewhere — it's broad-based expansion. Top 3 by absolute sales value (PublishDrive): Canada, the Netherlands, and the United States. This does not necessarily mirror Kobo's own top-revenue markets. With that context established, here's how the growth picture looks across all 15 tracked territories.

Year-Over-Year Growth by Country (PublishDrive Kobo Data)

Singapore's +348% growth closely aligns with Kobo Plus's launch in Singapore in March 2025. New subscribers discovered PublishDrive-distributed content in a newly available territory — a pattern that highlights the value of being enrolled in Kobo Plus before a new market opens. Growth across Southeast Asia more broadly is currently being driven by digital literacy initiatives and specific device partnerships in Singapore and Malaysia, making these markets increasingly actionable for authors who publish in English or in regional languages. Authors who were already in the Kobo Plus catalog were positioned to capture first-mover advantage in Singapore without any additional effort on their part.

The US at +157% reflects strong growth for PublishDrive publishers on Kobo US specifically — not a claim that Kobo US grew 157% overall. This likely reflects catalog expansion by PublishDrive publishers, Kobo Plus growth within the US, and reader base growth on the Kobo platform. It does not necessarily mean US readers are broadly migrating from Kindle to Kobo.

🇨🇦 Canada: PublishDrive's Largest Kobo Market by Revenue and a Key Kobo Self-Publishing Trend

Canada leads PublishDrive's Kobo revenue by absolute value. Rakuten Kobo is headquartered in Toronto, with strong retail partnerships and a large e-reader installed base. At +46% growth, even this mature, high-volume Kobo territory continues to expand. For independent authors, Canada represents one of the most compelling arguments for learning how to promote books on Kobo — it's a market where Kobo consistently outperforms other platforms, and where both retail and subscription channels are delivering meaningful returns.

The genre-level data for Canada adds further precision to that opportunity. The following tables show which categories are gaining the most ground among PublishDrive titles, across both retail and subscription channels.

Top Genres for PublishDrive Titles on Kobo Canada (Retail)

Top Genres for PublishDrive Titles on Kobo Plus Canada

Note: These rankings reflect PublishDrive titles specifically — not Kobo Canada's overall bestseller list.

🇳🇱 The Netherlands: PublishDrive's Second-Largest Kobo Market and a Model for Kobo Plus Growth

The Netherlands is Kobo's original subscription market (Kobo Plus launched there in February 2017 in partnership with bol.com). At +63% growth, it's outpacing Canada's growth rate despite being a more mature Kobo Plus market — which speaks to the depth of reader engagement rather than just new subscriber acquisition. Independent authors distributing through the best ebook aggregators for Kobo will find the Netherlands particularly receptive to English-language genre fiction. As with Canada, the genre breakdown reveals where that growth is concentrated most sharply.

Genre Dynamics: How Category Trends Are Shaping Kobo Self-Publishing Trends on Retail vs. Subscription

Within the PublishDrive catalog, genre dynamics diverge significantly between retail and subscription channels. The tables below rank genres by absolute sales value for PublishDrive titles — not Kobo's platform-wide bestsellers. For authors evaluating ebook pricing by genre, these signals are especially actionable. Understanding which genres perform best is a foundational step in learning how to promote books on Kobo successfully and how to increase Kobo sales in specific categories. Note especially the divergence between retail and subscription rankings — the channel you optimize for can significantly affect which genres you prioritize, and in some cases, the growth differentials between channels are striking enough to warrant a deliberate channel-first content strategy.

Top Genres — PublishDrive Titles on Kobo Retail (by Sales Value)

Top Genres — PublishDrive Titles on Kobo Plus Subscription (by Sales Value)

Turning to the subscription channel, the genre rankings shift meaningfully. Romance remains dominant, but several categories — including Self-Help and Comics & Graphic Novels — post dramatically higher growth rates on Kobo Plus than on retail, pointing to subscription-first reader behavior in those categories. This divergence is one of the most actionable signals in the entire dataset for authors who want to understand how to increase Kobo sales by channel rather than platform-wide.

Kobo Writing Life vs. PublishDrive: The Strategic Case for Self-Publishing Wide Distribution in 2025

If you're an independent author weighing Amazon vs. Kobo distribution strategies, the structural differences below are critical — especially if you want to know how to increase Kobo sales while maintaining wide distribution. Understanding the best ebook aggregators for Kobo distribution is equally important: using the right aggregator lets you manage Kobo Plus enrollment, territory pricing, and multi-channel analytics from a single dashboard. The choice between wide distribution and KDP Select exclusivity is one of the most consequential decisions in independent publishing, and the 2025 Kobo data adds new weight to the argument for going wide. Our wide distribution strategies guide walks through how to maximize reach without sacrificing revenue on any single platform. For a full overview of how PublishDrive handles this workflow, see our PublishDrive platform features page.

Kobo Plus is non-exclusive. Unlike Amazon's Kindle Unlimited program, which requires ebook exclusivity to Amazon via KDP Select, Kobo Plus does not require exclusivity. Authors and publishers can opt in to Kobo Plus while maintaining full distribution across all of the following channels simultaneously:

• Amazon retail
• Apple Books
• Google Play
• Barnes & Noble
• OverDrive
• Hoopla
• Storytel
• Tolino
• Dozens of other channels

Kobo Plus offers competitive per-read economics — with important caveats. The $2.20 figure is a network average across PublishDrive's publisher cohort and is not a guaranteed flat rate. Kobo Plus pays from a variable revenue pool based on minutes read, and because Kobo reports in 300-minute increments, the number of "reads" appearing in your dashboard can look different from what you might expect based on Amazon's per-KENP-page model. Standard industry estimates for a 300-page equivalent novel on Kobo Plus typically range from $0.95 to $1.50 depending on reading speed. For comparison, Kindle Unlimited pays approximately $0.0040–$0.0045 per KENP page, yielding approximately $1.20–$1.35 for a standard 300-page novel and approximately $0.90 for a 200-page work. Kindle Unlimited also operates at a much larger subscriber scale, particularly in the US, which is a meaningful consideration for authors whose audience skews American. For the same book read in each ecosystem, per-read payouts are platform-comparable for longer works — but the subscription audience size difference remains an important factor in any strategic decision. 

Kobo's geographic footprint complements Amazon's. Kobo has meaningful market share in Canada, the Netherlands, France, Belgium, and increasingly Southeast Asia — particularly Singapore and Malaysia, where growth is being driven by digital literacy initiatives and specific device partnerships. These are markets where Amazon has historically been weaker. 

These conclusions apply to independent authors and publishers evaluating wide-distribution strategy. They are less relevant for publishers who have chosen — for strategic reasons around Kindle Unlimited engagement, marketing simplicity, or catalog considerations — to remain Amazon-exclusive.

How to Increase Kobo Sales: Actionable Kobo Self-Publishing Tips for Independent Authors

Whether you're a first-time author or an experienced publisher looking to expand your ebook distribution strategy, here's how to get started selling books on Kobo — with or without PublishDrive. The steps below cover both how to sell on Kobo and how to promote books on Kobo once your titles are live. The most common mistake authors make is treating Kobo as an afterthought — uploading once and never revisiting pricing, Kobo Plus enrollment, or territory targeting. The data suggests the authors generating the strongest results are doing the opposite: actively managing Kobo as a primary channel. 

Option 1: Kobo Writing Life — Distribute Directly for a Hands-On Approach

For authors who prefer a hands-on approach and direct relationship with the platform, Kobo Writing Life is the straightforward route:

• Go to Kobo Writing Life and create a free account.
• Upload your EPUB file, add metadata, set your price, and select your territories.
• Opt in to Kobo Plus during the setup process — no exclusivity required.
• Best for: Authors who want a direct relationship with Kobo and are comfortable managing each retailer separately.

Option 2: Kobo Writing Life vs. PublishDrive — Use One of the Best Ebook Aggregators for Self-Publishing Wide Distribution

For authors going wide across multiple channels, an aggregator removes the need to manage each platform individually. This is especially valuable for authors with large catalogs or those publishing in multiple genres across different territories. With PublishDrive, a single upload covers Kobo and hundreds of additional channels:

• Upload once and reach Kobo, Kobo Plus, and 400+ other retail, subscription, and library channels simultaneously.
• Manage per-territory pricing, Kobo Plus enrollment, and sales analytics from a single dashboard on the PublishDrive platform.
• Best for: Independent authors and publishers going wide who want to minimize platform management overhead. Using one of the best ebook aggregators for Kobo means your entire catalog can be enrolled in Kobo Plus without managing the channel directly.

Key Steps to Increase Kobo Royalties — Regardless of Distribution Route

Whichever distribution route you choose, the following steps apply equally and represent the most reliable levers for improving Kobo revenue over time. These are not theoretical optimizations — each one maps directly to the data patterns observed in PublishDrive's 2025 Kobo dataset:

1. Format your ebook correctly. Kobo accepts EPUB. Use a clean, validated file. See our EPUB formatting guide for best practices.
2. Set competitive pricing. Review our ebook pricing guide to benchmark against what's working on Kobo in your category.
3. Opt in to Kobo Plus. The subscription channel is growing faster than retail on a percentage basis. Enrollment is free and non-exclusive. Note that Kobo Plus payouts are calculated from a variable revenue pool based on minutes read (reported in 300-minute increments), so per-read earnings will vary depending on how quickly your readers finish your book.
4. Target Kobo's strongest markets. Canada, the Netherlands, the US, and Singapore are high-growth markets for PublishDrive publishers. In Southeast Asia, growth is currently driven by digital literacy initiatives and specific device partnerships in Singapore and Malaysia — making these markets particularly actionable for authors targeting those geographies. Set territory-specific prices where relevant.
5. Monitor performance by channel. Track retail vs. Kobo Plus separately to understand which is driving results for your specific titles.
6. Promote books on Kobo through price promotions. Use Kobo Writing Life's promotional tools or coordinate promotions across channels via your aggregator. Timed discounts and free days in key Kobo markets — especially Canada, the Netherlands, and Singapore — can significantly accelerate discoverability.

How to Distribute to Kobo and Kobo Plus via PublishDrive: A Step-by-Step Overview for Self-Publishers

Getting your books onto Kobo and Kobo Plus through PublishDrive is straightforward. Using PublishDrive as one of the best ebook aggregators for Kobo means you can manage enrollment, pricing, and analytics for Kobo alongside 400+ other channels — all from the same dashboard. This workflow is particularly well-suited to independent authors who want to act on Kobo self-publishing trends without building a separate operational process for each platform. 

1. Upload your ebook. EPUB format, with properly formatted metadata, cover image, and ebook pricing. PublishDrive's platform includes an EPUB converter that accepts DOCX input if needed.
2. Select Kobo as a distribution channel. PublishDrive delivers to both Kobo's à la carte store and Kobo Plus.
3. Opt in to Kobo Plus. During distribution setup, select the Kobo Plus enrollment option. Non-exclusive: your book remains available everywhere else simultaneously. Keep in mind that Kobo Plus payouts are drawn from a variable revenue pool and calculated based on minutes read, reported in 300-minute increments — so the "reads" you see in your dashboard reflect that reporting standard rather than a simple page-count model.
4. Set pricing for Kobo territories. PublishDrive supports per-territory pricing for Canadian dollars, euros, and other currencies. 
5. Monitor and optimize. PublishDrive's dashboard shows Kobo retail and Kobo Plus performance separately, so you can track which channel drives results for each title.
