Community Platform ROI Calculator
Calculate whether a paid community platform (Circle, Skool, Mighty Networks) generates enough revenue to justify the monthly cost based on your membership pricing and expected growth.

Adjust the assumptions
Creator community on Circle with 50 members. A creator running a $29/month community on Circle ($89/month plan) with 50 paying members and a 7% monthly churn rate.
Why this calculator matters
Community platforms charge $39-119+ per month regardless of how many members you have. At small member counts, the platform fee can eat most of your revenue.
This calculator shows your break-even member count and profit at different scales so you can choose the right platform for your current stage.
Context and practical use
Use this when choosing between community platforms or deciding whether to launch a paid community.
The model focuses on direct membership revenue. If your community also drives course sales, sponsorships, or other revenue, the real ROI is higher than what this calculator shows.
Formula and assumptions
- 1. Monthly membership revenue = paying members x monthly membership price x (1 - churn rate)
- 2. Monthly platform cost = platform subscription + (per-member fees if applicable)
- 3. Monthly profit = membership revenue - platform cost
- 4. Break-even members = platform cost / (membership price x (1 - churn rate))
How this is calculated
Members x price x one minus churn gives gross revenue for the month. That is a deliberately cautious reading: it prices the month as though this month's cancellations have already happened. Transaction fees come off that figure, the flat platform fee comes off next, and what remains is monthly profit. Break-even members divides the platform fee by what a single retained member nets after fees.
Churn is applied as a flat monthly haircut rather than compounded across a cohort, so a twelve-month projection built from this will read high. It ignores annual plans, free trials, founding-member pricing and members who stay but downgrade. It also ignores indirect value entirely: the course sales, referrals and testimonials a good community produces appear nowhere in the revenue line.
A worked example
Paid community at 120 members
A $39 monthly membership on a flat-fee platform, with 6% of members cancelling each month.
- 1. Gross: 120 members x $39 x (1 - 0.06) = $4,399
- 2. Less 2.9% in transaction fees: $4,271
- 3. Less a $99 platform fee: $4,172 monthly profit
- 4. Break-even: $99 / ($39 x 0.94 x 0.971) = 3 members
Result
$4,172 of monthly profit, with break-even reached at three members.
The platform fee stopped mattering around member four, so the number to manage is the 6% churn: at that rate the whole roster turns over in under eighteen months.
Inputs this model expects
The inputs stay practical so the calculator is usable early, before the assumptions are firm. If an input label is unfamiliar, the glossary defines it.
| Input | What it means | Default |
|---|---|---|
| Paying members | Number of active paying members in your community. | 50 |
| Monthly membership price | What you charge each member per month. | 29 $ |
| Monthly churn rate (%) | Percentage of members who cancel each month. 5-10% is typical for communities. | 7 % |
| Platform cost (monthly) | Monthly subscription for your community platform. | 89 $ |
| Transaction fee (%) | Payment processing and platform transaction fees. | 3 % |
Where to go from the number
Circle
Flat monthly pricing, which is exactly the shape of cost this model assumes in the platform fee field.
Skool
Worth comparing when your member count is low enough that the fixed fee is still a visible share of revenue.
Community platforms
Fee models differ between flat, per-member and revenue-share, and each one changes the break-even figure above.
Paid membership pricing worksheet
Use it before the price input, because the membership price moves this result more than the platform choice does.
Frequently asked questions
What is community platform ROI?
What a paid community earns after the platform subscription and payment processing fees, given your member count, your price and your churn rate. Platform fees are flat, so the answer swings mostly on member count.
How is churn different from retention?
They are the same figure read from opposite ends: 6% monthly churn is 94% monthly retention. Churn is the more useful framing for pricing, because it tells you how many members you have to replace before you grow at all.
What churn rate is healthy for a community?
Five to eight percent a month is ordinary for a creator community, under five percent is strong, and above ten percent means people are not getting what they joined for. Fix that before you spend anything on growth.
Why is my break-even member count so low?
Because the platform fee is the only fixed cost in the model and your own time is not in it. Add your monthly hours times your rate to the platform cost field and the break-even number becomes a good deal more honest.
