🏆 Winner: beehiiv (for most growing newsletters)
beehiiv wins on fees once you're earning meaningfully from paid subscriptions, and it packs in real growth tooling — a referral/boosts network, an ad marketplace, and automations — that Substack simply doesn't offer. Substack still wins on day-one simplicity and zero monthly cost for small or all-free lists.
Choose beehiiv if you…
- Earn more than ~$490/month from paid subscriptions
- Want to monetize free subscribers too (ad marketplace)
- Want built-in referral/cross-promotion tools to grow faster
- Need workflow automations and deeper analytics
- Plan to build a full website, not just an email list
Choose Substack if you…
- Are just starting out with a small or free list
- Want the absolute simplest writing/publishing experience
- Prefer paying a percentage over a flat monthly fee while small
- Value Substack's built-in reader discovery network
- Don't need ads, automations, or a full website builder
Pricing & Fees: The Real Math
Both platforms are free to start writing. The difference is entirely in how they charge once you turn on paid subscriptions.
Substack charges no monthly fee, ever — instead it takes a flat 10% cut of your paid subscription revenue, on top of Stripe's standard payment processing (2.9% + $0.30 per transaction, plus a 0.7% recurring billing fee). All in, that's roughly 13-16% of your gross paid revenue.
beehiiv charges 0% platform commission on subscription revenue — you only pay Stripe's processing fee. But you do pay a flat monthly fee once you're past the free Launch plan (up to 2,500 subscribers): Scale starts around $49/month (or ~$43/month billed annually), scaling up with subscriber count.
The crossover point: below roughly $490/month in paid subscription revenue, Substack's 10% cut costs less in absolute dollars than beehiiv's flat fee. Above that, beehiiv's flat-fee model gets cheaper the more you earn, since the fee doesn't scale with revenue the way a percentage cut does.
| Model | beehiiv | Substack |
|---|---|---|
| Free plan | Up to 2,500 subscribers, unlimited sends | Unlimited subscribers & sends |
| Platform commission on paid subs | 0% | 10% |
| Monthly platform fee | From ~$43-49/mo (past free tier) | $0 |
| Payment processing | Stripe standard (2.9% + $0.30) | Stripe standard + 0.7% billing fee |
Growth & Monetization Tools
beehiiv is built specifically for growth: a referral/boosts network lets you cross-promote with other newsletters and pay per new subscriber, an ad marketplace lets you monetize free (non-paying) subscribers, and workflow automations handle welcome sequences and re-engagement without manual work. Analytics go well beyond open/click rate.
Substack keeps things simpler and writing-focused. It has a built-in recommendation network (other Substack writers can recommend your newsletter to their readers) which drives real organic discovery, but it doesn't offer an ad marketplace, boosts network, or automation builder — monetization is essentially limited to paid subscriptions and, more recently, a tipping feature.
For creators who want to grow and monetize aggressively, beehiiv's toolset is more complete. For creators focused purely on writing and who benefit from Substack's built-in reader network, Substack's simplicity is genuinely appealing.
Website & Publishing
Both platforms give you a full website (not just an email template), a podcast page option, and custom domain support. beehiiv's site builder has more customization depth for teams that want the newsletter to double as a media brand's homepage — you can build out a real homepage, category pages, and an author bio system rather than just a chronological archive. Substack's site is simpler and more opinionated, which some writers prefer for a distraction-free reading experience where the writing itself is the entire product.
Neither platform requires you to touch code to launch, but the ceiling differs: beehiiv scales toward "this could be a small media company's site," while Substack stays intentionally close to "this is a newsletter with a clean archive." Neither is wrong — it depends on whether you want the newsletter to be the product or the front door to a broader publication, and that choice is worth making deliberately rather than defaulting to whichever platform you happened to start on.
Data Ownership & Migration
Both platforms let you export your subscriber list at any time, so neither locks you in permanently. beehiiv additionally offers a dedicated migration tool and white-glove onboarding for creators moving over from Substack, Mailchimp, or ConvertKit, which reduces the friction of switching once you decide the fee math favors beehiiv. Substack's export is simpler — a CSV of subscribers and your post archive — but doesn't include the same guided migration support since Substack has less incentive to help you leave.
If you're evaluating a move from Substack to beehiiv specifically because your paid revenue has crossed the ~$490/month threshold discussed above, this migration tooling is worth factoring in: it typically takes an afternoon rather than days to move a list of a few thousand subscribers and preserve your existing archive.
Verdict
beehiiv wins for creators earning meaningfully from paid subscriptions, anyone wanting to monetize free subscribers via ads, and anyone who wants built-in growth automation rather than building it themselves.
Substack wins for writers just starting out, all-free newsletters that will never charge for subscriptions, and anyone who values Substack's built-in discovery network and minimalist writing experience over growth tooling.
Real-World Cost Examples
Numbers make this concrete. A newsletter with $300/month in paid subscription revenue would pay Substack roughly $30-48/month total in fees (10% cut plus Stripe processing), while beehiiv's flat plan starting around $43-49/month costs about the same or slightly more — a wash at this stage. A newsletter earning $800/month would pay Substack around $80-128/month, already more than beehiiv's flat fee, making beehiiv the cheaper option. At $3,000/month in paid revenue, Substack's cut climbs to roughly $300-480/month, while beehiiv's fee stays flat regardless of how much your subscription revenue grows — the gap only widens from there as a publication scales.
This is why the "$490/month crossover point" isn't just a rule of thumb — it's the rough breakeven where a flat monthly fee starts beating a percentage-based cut, and every dollar of paid revenue past that point is effectively free of platform commission on beehiiv but still taxed at 10% on Substack, month after month, for as long as the newsletter keeps growing.
A Practical Decision Framework
Rather than picking a platform based on brand reputation alone, run the actual numbers for your situation. If you're pre-revenue or earning under a few hundred dollars a month from paid subscriptions, the fee difference is small in absolute terms either way — pick based on which writing and publishing experience you prefer, since Substack's discovery network can meaningfully help a brand-new newsletter find its first readers.
If you already have a list of a few thousand subscribers and paid conversion is proven, model your actual monthly paid revenue against both fee structures before committing. A newsletter earning $2,000/month from paid subscribers would pay Substack roughly $200-320/month in fees (10% cut plus Stripe), versus beehiiv's flat $43-49/month plus Stripe's standalone processing fee — a difference of over $150/month that compounds significantly over a year.
The tie-breaker for many creators ends up being the growth tooling rather than the fee math alone: if you plan to actively grow through boosts/referrals or monetize your free-tier readers with ads, beehiiv's ecosystem does work that would otherwise require stitching together several separate tools on Substack — a referral program, a separate ad network, and a workflow automation tool, each with its own setup and learning curve.
