Community Hosting Economics: Base Subscriptions, Transaction Friction, and Scaled Net Margins

When building a recurring paid membership community (MRR), selecting the underlying software infrastructure is a critical business driver. Beyond headline subscription prices (e.g., $99/mo for Skool vs. $199/mo for Kajabi or Circle), hidden transaction percentage fees and redundant third-party email tools dictate true creator take-home profit. Accurately modeling total software overhead and cost per member ensures maximum bottom-line profitability as your community scales.

1. Foundational Community Hosting Equations

  • Gross Monthly MRR: Paying Members × Monthly Subscription Price
  • Platform Transaction Surcharge: Gross Revenue × Platform Fee %
  • Merchant Gateway Fees: (Gross Revenue × Stripe 2.9%) + (Members × $0.30)
  • Net Creator Monthly Profit: Gross MRR − Platform Base Sub − Platform Cuts − Payment Fees − Admin Overhead

2. Actionable Guidelines for Community Founders and Operators

Maximize community profit by migrating to 0% platform transaction fee suites (like Kajabi) once clearing $3,000/mo in MRR, consolidating standalone email marketing and funnel subscriptions into your primary LMS, and focusing on member retention to drive effective software costs per member below $2.00/month.

Frequently Asked Questions (FAQ)

Which community platform is most cost-effective: Skool, Circle, Mighty Networks, or Kajabi?▼

It depends directly on monthly recurring revenue (MRR): At low revenue (< $1,500/mo), Skool Pro ($99/mo) provides low entry costs. Once community revenue scales past $3,000 to $5,000/mo, Kajabi Growth ($199/mo) becomes commercially superior because it charges 0% platform transaction fees while replacing separate email marketing and funnel tools.

What hidden transaction fees do community platforms charge?▼

Beyond base subscriptions, platforms charge varying transaction cuts: Skool takes a 2.9% all-inclusive fee, Circle charges 1% to 2% plus standard Stripe processing (2.9% + $0.30), and Mighty Networks levies a 1% to 2% fee. Kajabi charges 0% platform transaction fees when using Kajabi Payments.

What differentiates All-in-One suites (Kajabi) from dedicated community tools (Circle, Skool)?▼

Dedicated community hubs (Skool, Circle) focus on discussion feeds, leaderboard gamification, and member directories, but require separate email marketing tools (ConvertKit/ActiveCampaign) and landing page builders. Kajabi bundles courses, funnels, email automation, podcasts, and community spaces on a single invoice.

How do you calculate Software Cost per Member?▼

Cost per member equals: `(Monthly Platform Subscription + Platform Cuts + Merchant Processing Fees) / Total Paying Members`. At 300 members on Kajabi Growth, software overhead averages under $2.00 per member/month.

Do platforms like Circle and Mighty Networks offer custom mobile apps?▼

Yes, all major platforms provide native iOS and Android apps. For fully custom white-labeled mobile apps published under your own creator brand name, Circle Plus and Mighty Pro offer enterprise tiers starting at several hundred dollars per month.

What is an optimal net profit margin for a paid membership community?▼

Healthy paid communities target net profit margins between 75% and 90% of gross MRR. Margins dipping below 60% indicate excessive software bloat, redundant third-party subscriptions, or inefficient payment fee structures.
