The sticker price is the beginning of the bill, not the end
Every community platform leads with a monthly number, and that number is almost never what you’ll actually pay. Total cost of ownership, the real, all-in figure once you add fees, add-ons, tier upgrades, and operational overhead, can be double or triple the headline. If you compare platforms on sticker price alone, you’ll choose wrong. Here’s a clear-eyed breakdown of what actually drives the true cost in 2026, and how the categories differ across the main platform types.
Cost driver 1: Transaction fees
For any community that charges members, the fee on member payments is often the single biggest hidden cost. Circle takes 1–2% by tier; Mighty Networks charges 0.5–2% and never reaches zero even on its top plan; Skool runs 2.9–10%. At $10,000/month in member revenue, a 2% fee is $2,400 a year, on top of your subscription, scaling up as you grow. This is the cost most comparisons ignore and the one that hurts most as you succeed.
Cost driver 2: Add-ons and tier upgrades
The features you actually need are frequently not on the plan you first sign up for. Branded mobile apps are a recurring example, a $149/month add-on on LearnWorlds, $199/month on Thinkific. White-labeling, automation, email, multiple communities, and API access are routinely gated to higher tiers. Kajabi reserves branded apps and API for its $399/month Pro plan; Circle gates white-label and automation to its $199 Business tier. Budget for the plan you’ll actually need, not the one you’ll start on.
Cost driver 3: The “free” platform’s operational cost
Open-source and self-hosted options look free and aren’t. Moodle is the clearest case: the software license is $0, but self-hosting runs $80–$500+/month in infrastructure, $2,000–$25,000+ in one-time setup, ongoing maintenance, and, the big one, staff time, often a quarter to a full dedicated administrator. Discourse is similar: free to self-host, but you’re paying for a server and the technical expertise to run a Ruby on Rails application. “Free” usually means “you supply the labor.”
Cost driver 4: The multiplier for multiple communities
This one is invisible until it isn’t. If you run more than one community on a single-community platform, every cost above multiplies, by the number of communities. Five communities on Skool is five $99/month subscriptions; five on Circle is five Business plans plus five sets of fees and add-ons. The platform that’s cheap for one becomes the most expensive option for five, purely because it wasn’t built to share infrastructure across communities.
How to calculate your real TCO
Build the actual number before you choose. Take the plan you’ll genuinely need (not the entry tier), add transaction fees at your target revenue, add the add-ons your model requires, add any operational or staffing cost for self-hosted options, and multiply by the number of communities you’ll run. That figure, not the sticker price, is your real comparison.
When you run that math, the picture often shifts. A platform built around a flat platform model rather than per-transaction fees, and one that’s multi-tenant rather than per-community, can come out dramatically lower at scale even if its headline price looks similar. Mobieus, built multi-tenant and on a platform model, is structured to avoid two of the biggest TCO multipliers, per-transaction skimming and per-community cost stacking; confirm its current pricing directly at mobieus.io and run it through the same TCO calculation. Whatever you choose, do the full math first, because the cheapest sticker price is regularly the most expensive platform.
Note: pricing, fees, and add-on costs change frequently; verify current figures with each vendor before deciding.
