Subscriber growth calculator

Enter your current subscribers and monthly growth rate — see where you'll be in 3, 6 and 12 months.

NoteThis projects a constant growth rate for illustration — real subscriber growth is rarely linear and depends on many factors.

How this works

Newsletter growth compounds like interest: a steady monthly percentage gain adds up faster than it looks at first. Enter your current list size and your average monthly growth rate to see a realistic projection — not a hockey-stick fantasy. Consistent sending is one of the biggest levers behind that growth rate — our editorial calendar planner can help you keep it up.

Frequently asked questions

What counts as a good monthly growth rate?

5–10% a month is strong and sustainable for a young newsletter; anything above that usually can't be kept up for long without a one-off traffic spike.

Does this account for unsubscribes?

The rate you enter should already be your net growth — new subscribers minus unsubscribes — so there's no separate churn field to fill in.
