FAQ
What does this tool tell you?
The Total Cost of Ownership Calculator models the real cost of SaaS contracts including hidden costs like onboarding, training, integration, and underutilization.
What affects the result most?
Year 1 total = vendor cost + internal labor (admin) + one-time fees. Seat waste % = (paid seats - active users) / paid seats. Verdict: Overpaying (>= 2 risk flags) | Tight | Reasonable | Lean.
How should I use the result?
The calculation is deterministic — the same inputs always produce the same output — so the most useful workflow is to vary one input at a time and see which factor moves the result most. That tells you where to focus your attention before committing to a decision.
