Substack made it easy to start a paid newsletter. But as your audience grows, the costs add up: 10% of subscription revenue to Substack, plus Stripe's processing fees. On $5,000/month in subscriptions, you're paying $500 to Substack alone—every month.
More importantly, you don't own your platform. Substack controls your publication URL, your recommendation algorithm placement, and can change terms at any time. Several prominent writers have already been affected by content moderation decisions.
This guide compares newsletter platforms and explains how self-hosted Ghost lets you own everything while keeping the features that matter.

The Revenue Math
Let's calculate the real cost of each platform at different revenue levels:
| Monthly Revenue | Substack Cost | Beehiiv Scale | Ghost (DanubeData) |
|---|---|---|---|
| $0 (free newsletter) | $0 | $0 | €7.99 |
| $500/mo | $50 | $49 | €7.99 |
| $2,000/mo | $200 | $49-99 | €7.99 |
| $5,000/mo | $500 | $99 | €7.99 |
| $10,000/mo | $1,000 | $99 | €7.99 |
Ghost costs are hosting only. Stripe's 2.9% + $0.30 per transaction applies to all platforms including Substack.
At $5,000/month in subscription revenue, Substack takes $500/month ($6,000/year). Ghost on DanubeData costs €7.99/month (€95.88/year). That's a $5,904 annual difference.

When to Stay on Substack
Substack isn't always the wrong choice. Consider staying if:
- You're just starting out: Substack's free tier and built-in discovery network help new writers find readers
- Discovery matters more than revenue: Substack's recommendation system can drive subscriber growth
- You don't want to manage anything: Zero setup, zero configuration—just write
- Revenue is low: 10% of $50/month is only $5—negligible
When to Switch to Ghost
- You're earning $500+/month: The revenue share becomes significant
- You want your own brand: Your domain, your design, your platform
- SEO matters: Content on your domain builds your search presence, not Substack's
- GDPR compliance: You need EU data residency for your subscriber data
- Platform risk concerns you: Open source means no deplatforming risk
- You want more than a newsletter: Ghost is a full publishing platform
