What does a newsletter platform cost in year one? "Which platform is cheapest?" has a wrong answer and a real answer. The wrong answer is "Substack, it's free." The real answer depends on your subscriber count and whether your newsletter earns money, because the one platform with no monthly fee takes a percentage of every dollar you make.
Here's the full math for year one.
What we compared
- Kit — free plan up to 10,000 subscribers; paid tiers billed yearly
- beehiiv — Launch free plan up to 2,500 subscribers; Scale from $49/month
- Substack — free at any list size; keeps 10% of paid subscription revenue (plus standard payment processing)
Prices come from each platform's official pricing page, scraped September 9, 2026. Kit and beehiiv both scale their prices with subscriber count, so the numbers below use the 1,000-subscriber tier as the reference point.
The three costs nobody separates
- Platform fee. What you pay the tool.
- Revenue share. What the platform takes from your earnings.
- The cap cliff. When your free plan forces an upgrade.
Most comparisons stop at #1. For newsletters the interesting money is in #2 and #3.
Scenario 1: 1,000 subscribers, no revenue yet
| Platform | Year-one platform cost | Notes |
|---|---|---|
| Kit | $0 | Free plan covers you to 10,000 subs |
| beehiiv | $0 | Launch plan covers you to 2,500 subs |
| Substack | $0 | No platform fee at any size |
Everyone's free. The difference shows up in the cap cliff: on beehiiv you hit the paywall at 2,500 subscribers, on Kit at 10,000, on Substack never. Growth-rate math: at 250 new subscribers a month, beehiiv's free plan lasts 10 months, Kit's lasts 40.
Scenario 2: 1,000 subscribers, paying $100/month in platform costs
Say you upgrade anyway for features (automations, removing branding, paid tiers).
| Platform | Year-one cost |
|---|---|
| Kit (Creator, billed yearly) | ≈ $390 |
| beehiiv (Scale) | ≈ $588 |
| Substack | $0 |
beehiiv costs the most here. What $588 buys: the ad network, Boosts, referral engine, and analytics that directly produce sponsorship revenue. If sponsorships are your model, that's a tool purchase, not a fee. If they're not, it's dead weight, and Kit at $390 or Substack at $0 wins your scenario.
Scenario 3: 1,000 subscribers, $100/month of PAID subscription revenue
Now the revenue share enters.
| Platform | Platform cost | Revenue share | Year-one all-in |
|---|---|---|---|
| Substack | $0 | 10% × $1,200 = $120 | $120 |
| Kit | $390 | $0 | $390 |
| beehiiv | $588 | $0 | $588 |
Substack wins the all-in number — barely — while your list is small. But notice the crossover: Substack's cost is a fixed percentage of your revenue, so it scales with success. At $1,000/month of paid revenue:
| Platform | Year-one all-in |
|---|---|
| Kit | ≈ $390 (paid tier) |
| beehiiv | ≈ $588 |
| Substack | $1,200 (10% of $12,000) |
The crossover points: Substack's 10% cut passes Kit's ≈$390/year fee at about $325/month of paid revenue, and beehiiv's ≈$588 at about $490/month. Past those lines Substack stops being the cheap option. Its $0 sticker is really a 10% commission on your entire publication, forever. Kit and beehiiv take no percentage; their costs are capped.
Scenario 4: the sponsorship case
If sponsors pay you $500/month, the platform cost flips meaning:
- beehiiv: $588/year buys ad network access, Boosts, and sponsor-ready analytics. Cost is roughly 10% of sponsorship revenue, with tools that generate more of it.
- Kit: $390/year, sponsorships via your own outreach and integrations.
- Substack: $0 and no sponsorship tooling; brands do exist there but you build every process yourself.
This is why "which is cheapest" is the wrong first question. Match the platform to the revenue model, then compare costs.
The one-line summary
- Zero revenue, building a list: Kit (longest free runway: 10,000 subs).
- Sponsorship business: beehiiv (the fee is the toolkit).
- Small paid publication: Substack (until about $325/month of paid revenue vs Kit, or $490 vs beehiiv — past those points the 10% costs more than the alternatives' fees).
- Selling courses/products: Kit (commerce is native; the others aren't built for it).
