- Enter a realistic value for Current members and complete the remaining required fields.
- Check that Monthly new members uses the period and unit shown beside the input.
- Review the headline estimate together with the detailed figures; no single output should be interpreted in isolation.
- Change one assumption at a time to understand which variable has the greatest effect.

Net Growth = New Members − Churned Members. Growth Rate = Net Growth ÷ Current Members × 100. Active Rate = Active Members ÷ Current Members × 100. Churn Rate = Churned Members ÷ Current Members × 100.
The calculator applies this relationship consistently to the values entered above.
What the result means
The headline figure summarizes the modeled community growth outcome under the current assumptions. The supporting rows separate important components so you can check whether the result is operationally or financially plausible.
Treat this as a planning estimate. Actual community growth outcomes can differ because of timing, fees, taxes, rounding, eligibility rules, market conditions, or data quality that the simplified model does not capture.
Begin with the prefilled scenario: Current members = 5000; Monthly new members = 600; Monthly churned members = 150; Active members = 1800. Record the result, then change Current members while holding the other inputs constant.
The difference between the two outputs shows the sensitivity of community growth to that assumption. Repeat with Monthly new members for a second comparison.
What does the Community Growth Calculator show?
It converts the entered Current members, Monthly new members, Monthly churned members, Active members assumptions into an indicative community growth result and a supporting breakdown.
How should I choose a value for Current members?
Use a current, documented figure when available. For forecasts, test a conservative case alongside your expected value rather than relying on a single assumption.
Why does Monthly new members materially change the estimate?
Monthly new members is part of the model's scale or rate relationship. Even a modest adjustment can compound or flow through several displayed figures.
Can I use the result as a final decision?
No. Use it to screen scenarios and identify trade-offs, then confirm material sales, marketing & audience decisions with source records and qualified advice where appropriate.
