The author provides a minimalist formula: (This month's bill - Bill 3 months ago) / (This month's users - Users 3 months ago) = marginal cost/user.

The core approach: the free version allows 12 location-based meetings per month, with overages billed based on actual usage months rather than subscriptions.
