Estimate your revenue
Before Substack's payment processing fees. Annual revenue is amortized to a monthly equivalent for the "from annual plans" figure so it can be added to monthly-plan revenue.
How the blended revenue estimate is calculated
Your paid subscribers are split between monthly and annual plans based on the percentage you enter. Monthly-plan revenue is straightforward (subscribers x price), while annual-plan revenue is divided by 12 to get a monthly-equivalent figure, so both can be added together into one combined monthly total - then multiplied by 12 for the yearly figure.
This is before Substack's payment processing fees, which reduce the amount that actually reaches you. It's also a snapshot based on today's subscriber counts, not a projection of future growth - pair it with the Growth Calculator if you want to see revenue change over time.
Questions
Does this account for Substack's fees?
No - the estimate is before Substack's payment processing fees, which reduce the amount that actually reaches you. Treat this as gross revenue, not take-home.
How does it handle a mix of monthly and annual subscribers?
You enter what percentage of paid subscribers are on the annual plan. Annual revenue is divided by 12 to get a monthly-equivalent figure so it can be added to monthly-plan revenue into one combined total.
Is this my actual current revenue or a projection?
It's a snapshot based on the subscriber counts and prices you enter right now - not a forecast. Use the Growth Calculator alongside it if you want to see how revenue might change as subscribers grow.
What's a reasonable free-to-paid conversion rate to expect?
There's no reliable public benchmark - it varies by niche, price, and audience trust. The Paid Conversion Calculator can show your own current rate to track over time instead of comparing to an unverifiable number.
