How to use
- 1Enter your current followers, monthly growth rate and target.
- 2Optionally enter social spend and revenue attributed to social for ROI.
How it's calculated

Frequently asked questions
What's a realistic growth rate?
Established accounts often grow 1–3% a month; fast-growing new accounts can reach 5–10%+ for a while before slowing.
Does growth really compound?
Partly — bigger accounts reach more people — but growth usually slows over time, so long projections are optimistic.
How do I measure revenue from social?
Use UTM links and your analytics platform's attribution to see sales that started from social clicks.
