SaaS AI Cost-of-Tenant Calculator Skill

Overview

A tier design that ignores per-tenant AI cost will produce a margin disaster. This skill installs the calculator: a tenant-level computation of monthly AI cost from first principles, with sensitivity, scenarios, and a worked African vertical-SaaS example. It is the operating tool behind saas-ai-unit-economics-and-cogs and the input to saas-ai-pricing-strategy.

The calculator answers four questions an AI-aware investor will ask within the first 30 minutes:

1. What does the median tenant cost you in AI per month?
2. What does the top-decile tenant cost you?
3. Where does the model break — what tier × usage profile turns negative-margin?
4. What levers protect margin without degrading the customer's experience?
