Beehiiv vs. Substack: Which Platform Offers the Lowest Fees?

As the newsletter economy continues to grow, creators are increasingly focused on the bottom line. The choice between top platforms like Beehiiv, Substack, and Mirror often comes down to their commission structures, which can significantly impact a writer's long-term take-home pay. While Substack remains a dominant force, its 10% cut on paid subscriptions is being challenged by newer competitors offering flat-fee models or lower percentage-based fees.

For independent creators, these platforms offer vastly different financial trade-offs. Beehiiv operates on a tiered subscription model for the creators themselves, allowing those with large audiences to keep a higher percentage of their revenue compared to traditional commission models. Meanwhile, Mirror leans into a decentralized approach, often appealing to web3 enthusiasts who want to avoid traditional gatekeepers altogether.

Looking toward 2026, the shift is clearly toward giving creators more control. Some reports indicate that by leveraging specific platform combinations, writers can now retain up to 97% of their total earnings. This movement puts pressure on legacy platforms to reconsider their fee structures or provide more robust growth tools to justify their higher costs.

As the market matures, watch for how these platforms handle the rising cost of payment processing and whether they lean further into advertising networks to subsidize low-commission models. For now, writers should audit their subscriber count and revenue projections before committing to a ecosystem. This comparison of creator earnings was first detailed by Quasa.
