How it works
Compare the cost that changes with your revenue
Substack is free to publish but takes 10% of paid subscription revenue. Flat-fee platforms generally charge according to plan and audience size. As paid revenue grows, the fixed monthly cost may become the less expensive model.
Pricing can change. Verify each provider’s official pricing page before making a decision.
