Substack writer numbers doubled to 100,000 earning money, but most make under $500 annually

Nearly 100,000 publications earn money on Substack as of April 2026, up from 50,000 in May 2025, marking a 100% increase in monetising creators in under a year. But behind the expansion sits a harder economic picture: the median creator earns around $4,000 annually, and nearly 50% of creators with paid subscriptions earned less than $500 in 2025.

The growth figures look like validation. Writers collectively earned $450 million in gross revenue through the platform in 2025, and Substack now has 50 million active subscriptions, with 5 million of those paid. But the distribution of that revenue follows a predictable power law: the top 10% captures 62% of all payments.

For social media professionals considering newsletters as a revenue stream, the opportunity is real but the path is narrow, and the numbers below the headline require closer attention than the platform's growth story suggests.

The real median sits at $4,000 per year, not $26,000

If you divide $450 million among the 17,000+ writers earning money, the average comes out to about $26,000 per year, but averages lie when the distribution is this skewed. The median is closer to $4,000 annually.

Among the broader international creator base, median annual creator earnings are around $4,000. Writers in the top quartile surpass $16,000 annually. That means three quarters of earning creators are making less than $16,000, and half are below $4,000.

The gap between the platform's total revenue and what the typical creator takes home isn't a quirk. It's structural. More than 50 publications earn at least $1 million per year, and the top 10 Substack publications earn over $25 million annually. Meanwhile, nearly 50% of creators with paid subscriptions earned less than $500 in 2025, and the top 10% captures 62% of all payments.

Churn hits 50% annually, requiring constant replacement

The single biggest operational reality most creators underestimate is subscriber retention. Annual churn averages approximately 50%. This means a creator with 600 paid subscribers loses around 25 every month and must constantly replace them just to keep income stable.

For new subscriptions to paid newsletters, on average, churn levels are around 50% a year. That means their income would fluctuate quite a bit, making earning that much tougher for writers.

To earn $50,000 annually at $8 per month, a creator needs roughly 900 active paid subscribers. For an annual income of $50,000 at an $8 monthly subscription price, a writer would need 900 paid subscribers. Beyond that, a writer must acquire 31 new subscribers every month just to maintain their income.

That replacement math changes the entire calculus of newsletter sustainability. Retention isn't a growth metric. It's a survival requirement. For social media marketers accustomed to platform churn, newsletter churn operates differently: each lost subscriber is recurring revenue walking out the door, and the subscriber you lose this month was generating $8 or $10 monthly before they left.

Most money goes to creators who arrived with existing audiences

The vast majority of newsletters earning over $500,000 per year belong to people with pre-existing audiences. Nearly all newsletters earning over $500,000 per year belong to people with pre-existing audiences.

The success stories driving Substack's brand are not representative of the path available to most. 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. Every one arrived with an established platform built elsewhere.

Roughly 30% of Substack writers come from journalism backgrounds, which helps explain why the platform's most visible successes are former reporters and columnists who brought loyal readerships with them. For creators starting from zero, the competitive environment is materially different.

A writer charging $10 per month needs roughly 100 paid subscribers to clear $900 monthly after fees, before tax. 1,000 paid subscribers at $10 per month generates $9,000 monthly after Substack's cut, around $108,000 annually before tax. That $108,000 figure is the floor most full-time Substack writers identify as sustainable, and 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.

What this means for social media professionals

The newsletter opportunity for social media marketers is real, but it follows established creator economy patterns: a small percentage earns well, the middle tier generates secondary income, and the majority earns almost nothing. That distribution isn't changing. If anything, it's tightening as more creators enter.

The strategic question isn't whether newsletters work. It's whether you're positioned to reach the thresholds where they work sustainably. Building to 500 or 1,000 paid subscribers is achievable but not automatic, and it requires consistent publishing cadence, niche specificity, and retention focus that most creators underestimate at launch.

A niche-specific Substack converts free subscribers to paid at 4% to 10%, versus 1% to 2% for broad-topic publications. Conversion rate and niche focus matter more than total subscriber count. A creator with 5,000 free subscribers converting at 6% generates 300 paid subscribers. At $10 monthly, that's $27,000 annually after Substack's 10% cut. Before churn.

For brands evaluating newsletter sponsorships, the same logic applies. A newsletter with 3,000 highly engaged subscribers in a specific niche is more persuasive to a brand than 30,000 social followers with diffuse interests. 77% of newsletters indicated interest in sponsorships and advertising partnerships in 2025, up from 72% the prior year. That figure reflects the direction of creator monetisation as a whole: brand deals and newsletter sponsorships are converging.

The platform is still growing, and around 30,000 of those monetising publications are outside the United States, showing international expansion. But the core economics haven't shifted: the median stays low, churn stays high, and the path to sustainable income remains narrow.

If you launch a newsletter in 2026, expect to spend 18 to 24 months building before you clear $1,000 monthly. Expect to lose half your paid subscribers every year. And expect the top earners to keep taking the majority of platform revenue while you're still replacing the 25 subscribers who churned last month.
