What topics pay the most?
These categories get the most paying subscribers. Choosing what to write about has never been more strategic.
Choosing what to write about has never been more strategic if you want to turn writing into a stable income stream. Paid newsletters have seen a steep rise in popularity in the past few years, and since the launch of monetization on Fika, writers have another platform to build their audience and make a living from their writing. But that also depends on finding the highest converting topics and figuring out what readers are happy to pay for.
Before we deep dive into the highest earning topics on one of the biggest newsletter platforms, we need to understand that this data is quite hard to come by. The numbers in this article are based on the little data available online, as well as existing leaderboards-based analysis of Substack categories from a variety of Reddit posts.
Although the numbers are estimates, not official Substack metrics, they are still useful for determining what pays—the why will be the focus of this article, which you need to understand to start earning on Fika.
For writers joining Fika, a fast-growing platform for your independent publications, these patterns can shorten the path to sustainable income by helping you decide what to offer your readers and why they might pay.
1. Some of the highest paying blog niches revolve around passion
According to the information available online, some categories stand out for their estimated paid engagement even with smaller audiences. This means that despite not having as many readers overall, a high number of those still become paying subscribers.
The categories in this list are:
Music
Faith & Spirituality
Sports
Comics
Literature
Why someone pays to read publications in these niches
Readers who pay to read in this niche most often do it for these reasons:
A sense of belonging: Readers feel part of a small, meaningful circle around a voice or worldview they care about.
Finding community: Company and companionship online connected in music taste, spirituality, fandom, or a love for reading a specific author's works.
Real relationships: Being more closely connected with a creator they admire.
A paid subscription in this niche offers readers something more than just articles. A few things that paying can give subscribers may be:
Closer access to the creator
Q&As
Discussion
Calls
Behind-the-scenes content
More context than free articles give
Longer essays or those that go one step deeper
Detailed commentary
Spiritual reflections tied to their day to day
Personalized astrology readings
To support the writer, not just consume content.
Tips for writers on Fika in these niches
If your writing covers any of those topics, consider the added value you can bring to readers who want to buy a paid subscription to your publication.
Continue publishing free posts to show people who you are. Free tiers give people a chance to get to know you. Paid posts are your opportunity to invite people closer to your work, whether that is a spiritual experience you want to share, a close reading session, or a detailed breakdown of a sports match that true fans will care about and want to discuss in detail.
Because Fika:
Delivers every issue straight to their inboxes,
Lets you set free vs. paid per post,
Removes technical setup
You can design an experience for readers in your niche: a time and place where your followers always feel seen.
2. Other high paying blog categories have lower conversion, but more people who pay
Some topics are very broad and have the potential to attract huge audiences. Because these topics are broad, you have the opportunity to either cover everything or go really up close and write about one segment of the topic from a specific point of view.
This means on one hand you face tough competition, but have the potential to attract people from all sorts of backgrounds. Or you can approach the topic from your own perspective and write about a topic people are generally interested in, while making your voice what sets you apart from others covering the same topic.
Both approaches are valid and they both factor into why people pay to read newsletters in this niche.
Why someone pays for these newsletters
Here, readers usually pay for clarity, time saved, and confidence:
U.S. Politics: to have one voice they trust to filter news for them that would otherwise be overwhelming. You save them from doomscrolling and help them feel informed without breaking screentime records.
Tech: to keep up with news that they feel is especially helpful for them. You help readers stay ahead of trends and understand the basics, so they can apply it to their work or investments.
Culture: People want a voice that filters and explains goings-on in the world around them. Part information, part entertainment.
Food & Drink: This can be anything from searching for the answer to “what should I cook tonight?” to “what should I eat” in general. It is more than a question of taste, however, because as the saying goes, “you are what you eat.”
Podcasts: Where people go when they can’t read (in the car or in the shower) or don’t want to (eyes strained from too much reading) read. They pay for bonus episodes, ad-free listening, or access to community discussion around what they listen to.
A few things to offer paying subscribers:
A curated, filtered source of information: give readers fewer, better sources so they can save time by not having to track everything themselves.
Context & Relevancy: Tell your “what this means for them this week,” especially if the info you share is business- or investment-related.
Access to more: bonus episodes, Q&As, reports, or early access.
Writer tips for publications on Fika
If you’re in politics, tech, business, or a “culture” niche on Fika, design your paid tier to promise readers better decisions and less mental load.
Think about the following: “one weekly brief so you don’t need to follow 20 sources,” “practical AI updates for non-technical teams,” or “weekly menu planning done for you.”
Think in formats: paid weekly briefings, dashboards, templates, or summaries readers can act on.
Fika gives you levers to work with here:
Use automatic translation to reach a larger audience (e.g., explaining a policy in your country and translating it to English for an international audience).
Use evergreen content on your blog to attract visitors with articles on certain topics (“Top 10 Museums to Visit in Paris”), then use your newsletter to send weekly recommendations.
Use analytics to identify what readers are most interested in (i.e. what has the highest open rate), then think of how you can create more of that.
3. Some publication categories sit in the middle
These categories have strong engagement and still have an above-average number of paid subscribers. They are niches where success is often driven by expert knowledge and interpretation.
Why someone pays for these newsletters
Readers who subscribe to these niches usually pay for:
Insights they can act on: What to do differently with their money, how to approach their health, or who or what to vote for and why.
Guidance: Ways of thinking that help them understand uncertain situations.
Shortcuts: Instead of reading dozens of sources, they trust you to digest and explain the topic.
What paid often buys in these blogs:
Deeper analysis with clear takeaways.
Regular short briefings, or dashboards they can rely on.
Bonus materials and direct access:
Q&As
Portfolio reviews
Case studies
How Fika can help you:
On Fika, design a paid tier that feels like a connection to you and your expertise, not just extra content:
Structure your free posts to cover headlines and overviews, and your paid posts to focus on more detailed breakdowns and decisions. Make those topics an ongoing series.
Because Fika handles delivering posts, translations, and technical setup, you can invest time in research and explanation. These are the things that actually justify subscriptions in these niches.
4. Blog niches where community drives monetization
Categories related to lifestyle and creative fields also show interesting patterns according to online data. These niches may not reach politics- or finance-level revenue, but they often have strong emotional loyalty and help you build community around your business while potentially creating another income stream.
Why people subscribe to these newsletters in these niches
Readers of these topics typically pay for:
Taste and curation
Shared experience
Inspiration and ideas put into practice: ideas they can actually apply to their wardrobe, home, trips, or creative field.
Paid subscriptions for these blogs often include:
Detailed guides:
capsule wardrobes and sewing templates
itineraries
studio processes
A peek inside the creative process:
mood boards
work-in-progress and drafts
behind-the-scenes
Community spaces
Fika is a good fit for you:
Use automatic translation to reach a larger audience. Travel and design are inherently international and interest more than just tourists and fashion outsiders. Invite a larger group of people to your publication by publishing in more than one language. Readers will see the post in their preferred language.
5. Use data to create a successful paid subscription strategy for your publication
Although these percentages and averages are rough estimates from a single Substack-focused analysis, combined with a common sense approach they show what a broader search on the web and creators we know report:
People subscribe for many reasons, but a sense of belonging and community are a big part of it.
You don’t need thousands of paying subscribers to build a stable income source. Focus on providing value, and your readers will find and support you.
Your voice and presence matter as much as, or in some cases more than, the topic you write in.
On Fika, you have three big advantages building your audience:
Ownership: algorithms don’t rule who you reach with your publication.
Simplicity: no technical setup, plugins, or themes; just writing, sending, and a readership that grows with you.
Translation: although the paid newsletter boom is underway, not many platforms focus on reaching an international audience. You can attract many people to your publication by offering it in more than your own language.
6. Choosing your newsletter niche and building your offer on Fika
When you decide what to write about, of course it is important to choose something you are passionate about. Strategy comes in when you decide how you write about your chosen topic. For this, it is important to know your audience as much as it is to know yourself. However, when setting up paid tiers, it is also important to take that a step further and understand what people want and what they are willing to pay for.
Ask yourself these questions to create a paid strategy that works.
What is my niche?
Who reads my posts?
What do people in this space pay for?
What will paid subscribers get that they cannot get from my free work or free internet content?
Is that difference clear in how I describe my tiers on Fika?
Fika’s analytics tools will help you understand your audience and answer these questions, but connecting with your audience to get a feel for who they are is also important.
Fika gives your writing a home to build exactly the kind of publication you want—one you own, and one your readers will follow and support over time. Start publishing today and build your community.
