Is Substack free? Yes, Substack is completely free for readers to read public articles and for writers to write, host, and email newsletters to subscribers. The platform does not charge monthly plan fees or put caps on subscriber list size, taking a 10% cut only when a writer turns on paid subscriptions.
What Free Access Means for Readers vs Newsletter Writers
Understanding whether Substack costs money depends on whether you are using the platform as a consumer or as an independent publisher. For readers, creating a Substack account, subscribing to newsletters, and receiving post deliveries via email or the mobile app is completely free. Readers only pay if they choose to subscribe to a writer’s paid tier, which unlocks premium posts, full archives, private podcast feeds, or subscriber-only comment threads.
For content creators, Substack operates on a freemium publishing model that differs significantly from traditional software service providers. Unlike legacy email software that charges tiered monthly management fees as your subscriber count grows, Substack provides core publishing tools without upfront charges. Writers can register a publication, publish web articles, and deliver broadcast emails to unlimited subscribers without ever entering a credit card.
Readers can explore discoverable content using the web directory or mobile applications. Through features detailed in our overview on How the Substack App Drives Reader Growth and Revenue, readers can follow publications, post comments, and receive push notifications without paying platform usage fees.
Zero-Cost Writer Features and Storage Boundaries on Substack

How Substack Charges Fees When You Launch Paid Subscriptions
Substack’s business model aligns directly with paid creator revenue. The platform remains free until a creator decides to enable paid memberships. When a reader purchases a subscription, two distinct fees are deducted from the gross transaction before net funds reach the writer’s bank account.
First, Substack retains a flat 10% platform fee on all paid reader transactions. Second, standard credit card processing fees are assessed by Stripe, the payment processor integrated into Substack. In the United States, Stripe’s merchant processing fee is typically 2.9% plus $0.30 per successful transaction. Processing rates vary slightly by geographic region (for instance, lower card fees generally apply in the UK and European Union, while standard card rates apply in Canada and Australia).
To evaluate how these fees affect creator earnings, consider a standard $5.00 monthly subscription purchased by a reader in the US:
- Gross Subscription Price: $5.00
- Substack Fee (10%): -$0.50
- Stripe Fee (2.9% + $0.30): -$0.45
- Net Creator Payout: $4.05 (81% net retention)
On larger transaction sizes, net retention rates increase because the fixed $0.30 transaction fee represents a smaller percentage of the total charge. For example, on a $50.00 annual subscription:
- Gross Subscription Price: $50.00
- Substack Fee (10%): -$5.00
- Stripe Fee (2.9% + $0.30): -$1.75
- Net Creator Payout: $43.25 (86.5% net retention)

Tax regulations apply to earnings generated through paid subscriptions. In the US, Substack and Stripe issue Form 1099-K tax documents to eligible independent contractors based on federal reportable threshold rules. Similar tax reporting obligations exist for creators in the UK, Canada, and Australia; creators should consult a qualified tax professional regarding self-employment reporting.
Reader Paywalls, Free Previews, and Subscription Options
Writers control which specific posts are free to the public and which posts require a paid membership. When creating a post in the Substack dashboard, authors select the intended target audience: Everyone (Free), Paid Subscribers Only, or Founding Members.
To convert free readers into paying supporters, creators can use paywall breaks inside individual articles. This allows a writer to show the first few paragraphs of an article for free before asking readers to subscribe to read the rest. Writers can also set up free trials or send promotional discount codes through the dashboard settings.
Key monetization options available on Substack include:
- Monthly Subscriptions: Recurring payments set by the creator, subject to platform minimum pricing rules.
- Annual Subscriptions: Discounted yearly rates designed to lock in longer reader retention.
- Founding Member Tier: An elevated support tier that allows passionate readers to contribute higher customized dollar amounts per year.
- Group Subscriptions: Discounted bulk accounts for corporate teams, educational institutions, or groups of readers.
Substack Free Plan Questions Answered by Writers

No. Substack takes 0% of your earnings if your publication is free. Platform fees only apply when paid transactions occur through your Stripe payout account.
