If you use Substack, should you stay on it? You might want to leave because of its Nazi problem, and that’s a good reason to do so. However for this post I’d like to focus on why you might you might want to leave for financial reasons.

To see what I mean about financial reasons, take a look at this chart above. I found it via this post on Bluesky: “Here’s some napkin math for how expensive Substack is compared to its competitors, assuming that roughly 7% of all subscribers will pay for their subscriptions, and that subscriptions cost $5/month. — Molly White (@molly.wiki) April 11, 2025 at 10:47 AM”. According to the chart, once you get above 18 paid subscribers, it gets worse and worse to be on Substack vs some of the other platforms there. And if you have 350 paid subscribers, all of the alternative platforms are cheaper.

I commented that I thought 7% was the highend, since I’ve seen a numerous substacks with 3% pay/free, but she replied she got the 7% from substack. Fair enough. I did come across this chart that showed the percentage varies, depending on the substack topic. Regardless of what percentage of your followers are paying one, once you start getting a significant number of paying subscribers, you should consider moving.

If you still need convincing that switching seems like a good move, read this.
