How much money can you make on Substack?

Short answer: most Substack writers earn little or nothing, a solid middle tier earns a meaningful side income, and a tiny fraction earns a full living or more. The platform's economics are simple and transparent. The hard part is getting enough readers to pay.

Substack's pitch is appealing: write, gather subscribers, charge for premium content, keep the lion's share. And the fee structure really is writer-friendly compared to most platforms. But friendly fees on zero revenue are still zero, and the distribution of earnings on Substack is brutally top-heavy.

Let us look at the actual numbers, the actual math, and what it realistically takes.

How Substack pays writers

The model is straightforward. You publish free content to build an audience, then offer paid subscriptions for premium posts. Substack takes 10% of your subscription revenue. Stripe, which processes the payments, takes its standard cut: around 2.9% plus $0.30 per transaction, plus a small recurring billing fee on subscription renewals.

In practice, expect to keep roughly 83% to 87% of what readers pay, with annual plans keeping slightly more than monthly ones because the fixed per-transaction fee hits once instead of twelve times. There are no upfront costs and no fees until someone pays you, which makes starting free and risk-free.

That is genuinely good as platform deals go. The catch is not the fees. It is everything before the fees.

The shape of earnings: most earn little

Substack has said that more than 100,000 publishers earn money through subscriptions, and announced 5 million paid subscriptions in early 2025. Divide one by the other and the average is about 50 paid subscriptions per earning publication. Averages mislead, because a handful of giant newsletters pull the number up, but the direction is clear: the typical earning writer has dozens of paying readers, not thousands.

Independent analyses have consistently found that the vast majority of subscription revenue concentrates at the top. A small percentage of creators captures most of the money, while most writers with paid tiers enabled earn modest amounts. Dozens of paid subscribers at typical prices means hundreds of dollars a year, not thousands a month.

This is not a flaw in Substack. It is the shape of every creator platform. But beginners should know the shape before they imagine themselves in the thin tail.

The conversion math

Here is the equation that determines your income: free subscribers times conversion rate times price, minus fees. Each variable is harder than it looks.

Free subscriber growth is the first mountain. Getting to a few thousand free readers takes months of consistent publishing, promotion, and often an existing presence elsewhere. Most newsletters stall in the hundreds.

Conversion from free to paid is the second mountain. Substack's historical guidance suggested 5% to 10%, but independent analyses of paid newsletters put typical conversion far lower, often in the low single digits, with the median around 1% or less for many publications. Top performers reach higher, but planning your finances on top-performer numbers is how disappointment happens.

Price is the third variable. Most paid newsletters charge somewhere in the single digits to low teens per month, or the equivalent annually. Higher prices convert fewer readers. Lower prices need more of them. There is no free move.

Run the math on a realistic case: 3,000 free subscribers, 2% converting at $8 a month. That is 60 paying readers, $480 a month gross, roughly $400 after fees. Respectable as a side income. A long way from a living.

What the top actually earns

At the far end, the numbers are real and large. Substack's leadership has confirmed dozens of publications earning over a million dollars a year, and the top names in categories like finance, politics, and technology earn far beyond that. The top ten authors collectively earn tens of millions annually.

These writers share traits worth noting. Most arrived with an existing audience or reputation. They publish in categories where readers have money and strong opinions: investing, business, politics, technology. They publish consistently, often for years before the income became serious. And they treat the newsletter as a business, with marketing, pricing strategy, and audience development, not just writing.

The lesson is not that you cannot join them. It is that the path runs through years of audience building, usually in a lucrative niche, with professional-level consistency. Anyone promising faster is selling something.

The churn treadmill

One underappreciated reality: paid subscriptions churn. Analyses suggest typical newsletters lose roughly half their paid subscribers each year to cancellations and expired cards. That means a writer earning from 500 paying readers must add about 250 new ones annually just to stand still.

This treadmill effect is why Substack income feels precarious even when the numbers look good. Growth is not just about reaching a target. It is about outrunning constant attrition. Writers who stop promoting and publishing consistently watch their income decay, sometimes faster than they expect.

The practical implication: your marketing never ends. The newsletter is the product, but audience acquisition is the job. Writers who love writing but hate promotion often struggle here, because on Substack the two are inseparable.

Paths that actually work

The writers who build real income tend to follow recognizable patterns. The expert play: deep knowledge in a valuable niche, free content that proves the expertise, paid tier for the actionable layer. Finance and business newsletters dominate the top earners for a reason: their readers can justify the cost as an investment.

The personality play: a distinctive voice on culture, politics, or current events that readers feel loyal to. This converts on identity and community rather than utility. It is harder to replicate but powerful when it works.

The bundle play: the newsletter as one piece of a larger business — courses, consulting, community, books. Here Substack revenue is secondary, and the newsletter functions as marketing that pays for itself. Many successful writers earn more from what the audience buys than from the subscriptions themselves.

What does not work reliably: writing about everything, publishing sporadically, charging before you have an audience, or assuming good writing alone converts. The market rewards focus, consistency, and a clear reason to pay.

The free content that feeds the paid tier

The engine of Substack income is free content, which surprises beginners who think the paid posts are the product. Free posts are what get shared, recommended, and discovered. Every paying reader was first a free reader who found enough value to open their wallet.

This creates a strategic question: how much do you give away? Give away too little and nobody discovers you. Give away too much and nobody needs to pay. Successful writers solve this with a clear split: free content that is genuinely useful and shareable, paid content that goes deeper, more actionable, or more personal.

Common splits that work: free weekly analysis with paid deep-dives, free essays with a paid community or Q&A, free news roundups with paid original reporting. The pattern is that free content demonstrates your thinking and paid content delivers the parts readers cannot get elsewhere.

One more subtle point: your best marketing asset is other writers' recommendations. Substack's recommendation network lets publications suggest each other, and a recommendation from a larger newsletter can add hundreds of subscribers overnight. Being generous with recommendations, engaging genuinely with other writers, and writing the kind of free content others want to share are all part of the job.

Setting honest expectations

If you are starting from zero, a realistic first-year goal is building a free audience and learning what resonates, with paid revenue as a bonus rather than the plan. Writers who enable paid tiers too early often find that a paywall on a small audience just slows growth.

A realistic second act: with a few thousand engaged free readers and a clear premium offering, a few hundred dollars a month is achievable. That is genuine money, and for many writers it is the validation that keeps them going.

A full-time living from Substack alone is achievable but rare, and it typically requires tens of thousands of free readers, strong conversion, and years of work. Treat it as a possible outcome of a long game, not the expected result of starting.

Substack is one of the fairest deals in the creator economy: no gatekeepers, writer-friendly fees, and you own your email list. But fairness is not the same as easiness. The money is real, the top is lucrative, and the middle is a perfectly respectable side income. Just go in knowing which part of the distribution you are likely to land in, and build from there with clear eyes. Write consistently, serve a specific reader, and let the paid tier be the natural next step for your most engaged fans rather than a gamble on strangers.
