Substack Fee Calculator | 서브스택 수수료 계산기

Estimate how much Substack actually keeps after platform fees, payment processing, recurring billing drag, and refunds. Then reverse the model to see how many paid subscribers you need to reach your target monthly net income.

Assumption posture: this is a planning model, not accounting or legal advice. Fee defaults are editable because published Substack help snippets have varied on the recurring billing fee. Keep your assumptions current before making a pricing decision.
