The platform’s success stories are real. The median is not what you think.
Substack has become the go-to symbol of the independent writer’s dream. Quit the newsroom, launch a newsletter, build a direct relationship with your readers, and get paid. The pitch is clean, the case studies are compelling, and the platform’s growth numbers — over 35 million paid subscriptions as of 2024 — lend it credibility. But the headline figures tend to obscure a more complicated picture. How much Substack writers actually make depends on factors the platform’s marketing rarely emphasises: audience size, niche, pricing, and the years of trust-building that typically precede any meaningful income.
The numbers at the top
Substack’s most visible earners are genuinely impressive. Heather Cox Richardson’s Letters from an American reportedly generates over $5 million annually. Matt Taibbi’s Racket News, Glenn Greenwald’s System Update, and Judd Legum’s Popular Information are estimated to earn seven figures each. The company’s own data suggests that its top ten writers collectively earn more than $25 million per year.
These figures are real, but they represent a vanishingly small percentage of the platform’s total publishers. Richardson, Taibbi, and Greenwald arrived on Substack with massive pre-existing audiences — built over decades in mainstream media. Their Substack income is less a product of the platform than a transfer of loyalty from one medium to another.
What the middle looks like
Substack takes a 10% cut of subscription revenue, which means a writer charging $10 per month needs roughly 100 paid subscribers to clear $900 monthly after fees — before tax. That’s a liveable supplement in some markets; it’s not a salary.
The platform does not publish median earnings data, but independent analyses and creator surveys paint a consistent picture. The majority of Substack writers with paid tiers earn under $1,000 per month. A meaningful cohort — those with between 500 and 2,000 paid subscribers — earn enough to treat it as serious secondary income. A much smaller group, typically those with 5,000 paid subscribers or more, earn enough to write full-time.
To put that in concrete terms: 1,000 paid subscribers at $10 per month generates $9,000 monthly after Substack’s cut — around $108,000 annually before tax. That’s the threshold most full-time Substack writers point to as the floor for sustainability. Getting there typically takes two to four years of consistent publishing.
What actually drives earnings
Niche matters more than most new Substack writers expect. Finance, politics, and culture newsletters consistently outperform general interest writing because readers in those categories have demonstrated willingness to pay for information they act on. A financial newsletter with 800 paid subscribers can out-earn a personal essay newsletter with 3,000 because the perceived value of the content — and the conversion rate from free to paid — is higher.
Pricing is the second lever. Many writers default to $5 or $7 per month out of nervousness, leaving significant revenue on the table. The most successful Substack operators tend to charge $10 to $15 monthly, or $100 annually, and offer founding memberships at $200 or more for readers who want to signal deeper support. Higher prices do not always mean fewer subscribers — in many niches they signal quality and attract more committed readers.
Free-to-paid conversion is the third factor. Most Substack newsletters convert between 3% and 10% of free subscribers into paying ones. A writer with 10,000 free subscribers converting at 5% has 500 paid readers — generating around $4,500 per month at $10. The same list converting at 8% generates $7,200. Building that conversion rate is less about tactics than about trust: consistent publishing, a clear editorial identity, and content that feels worth paying for.
Case studies: three different paths
Lenny Rachitsky spent years as a product manager at Airbnb before launching Lenny’s Newsletter in 2019. By targeting a specific professional audience — product managers and startup operators — and publishing consistently useful, experience-backed content, he built one of Substack’s most successful newsletters. He reached 500,000 subscribers and crossed seven figures in revenue within four years. His path illustrates how professional authority, combined with niche focus, accelerates the timeline significantly.
Anne Helen Petersen came from BuzzFeed with an established readership and a clear cultural beat — work, burnout, and American life. Her newsletter Culture Study converted a substantial portion of that existing audience quickly, reaching tens of thousands of paid subscribers. Her case demonstrates that platform migration, when done with an engaged existing audience, can compress years of list-building into months.
Edwin Dorsey launched The Bear Cave in February 2020 as a final-year economics student at Stanford, with no media platform and no existing audience. His newsletter focuses on corporate misconduct — short-selling analysis and investor fraud — a niche narrow enough to attract highly motivated readers willing to pay. He cold-emailed college investment clubs across the country and DM’d his entire Twitter following individually to build his initial list. Within months of launching a paid tier, he crossed $100,000 in annual revenue. By 2023 he was generating over $500,000 per year from around 1,300 paid subscribers at a premium price point of $440 annually. His case is the clearest proof that niche authority, not audience size, is the real driver of Substack income.
What Substack doesn’t tell you
The platform has a structural incentive to showcase its biggest earners. Those stories drive sign-ups, which drives platform revenue. What gets less attention is the volume of newsletters that launch, publish inconsistently for six months, and quietly stop. Substack itself has no reliable published data on abandonment rates, but the pattern is visible — browse any niche and you’ll find dozens of newsletters whose last post was eighteen months ago.
The writers who succeed share a few consistent traits: they publish on a schedule they can sustain, they have a specific enough focus that readers know exactly what they’re getting, and they treat the transition from free to paid as a business decision rather than an emotional one.
Substack works. But it works on a longer timeline, and for a narrower set of niches, than its most prominent success stories suggest.
Key takeaways
The top earners on Substack are outliers, not benchmarks — most arrived with existing audiences built elsewhere. Median earnings are modest, but 500 to 1,000 committed paid subscribers represents a viable secondary income for most writers. Niche focus, consistent publishing, and confident pricing drive conversion more reliably than audience size alone. Full-time Substack income is achievable, but realistically takes two to four years to build from scratch — and requires treating it as a business from day one.
