Start with the question
The Substack decisions this hub helps you make
Each tool answers a different business question. Begin with the decision in front of you, not with a random number.
Paid newsletter revenue depends on more than subscriber count. Monthly versus annual plans, the annual discount, Substack's 10% platform fee, Stripe processing, and free-to-paid conversion all change the result you can plan around.
Start with Revenue when you are forecasting a list, Pricing when you are solving for an income target, Fees when you need a clean platform cost breakdown, and Profit when writing, editing, software, and tax reserves belong in the business case.

What to use next on Substack
A practical route through the calculator families, based on the work sellers do before and after a sale.
Before setting a paid subscription price
Run Substack Pricing with the net monthly income you want, the paid subscriber count you can support, and the annual discount you plan to offer. It works backward from the income goal after platform and payment fees.
Use Substack Pricing
When forecasting a paid newsletter
Use Substack Revenue to compare free-to-paid conversion, monthly subscribers, annual subscribers, and the monthly equivalent of annual plans. Keep the forecast tied to the audience and retention assumptions you can defend.
Use Substack Revenue
When checking the cost of each paid reader
Use Substack Fees to separate the 10% platform charge from Stripe's percentage and fixed transaction cost. Try monthly and annual mixes to see how billing frequency changes the effective fee rate.
Use Substack Fees
When testing whether the newsletter pays
Run Substack Profit with content, editing, software, and tax-reserve inputs. The result connects subscriber revenue to the operating costs that determine whether publishing creates a healthy monthly profit.
