SaaS stack waste finder

Short answer

Quick triage: enter your tool count, annual spend, and rough % of features actually used. Returns wasted spend, savings from a 20% trim, and the next audit's payback.

When this calculator helps

  • Annual board-deck slide showing the cost of SaaS sprawl.
  • Building the case for a FinOps role or vendor management hire.
  • Setting the audit target before the actual deep-dive begins.

When to look elsewhere

  • Stacks under 10 tools, the audit overhead exceeds the savings.
  • When you have already-instrumented utilization data per tool (use that instead of a guess).

Frequently asked questions

How accurate is the 'estimated waste' number?

Directional only. Real audits typically find 60-80% of the modeled waste once you account for must-keep low-utilization tools (security, compliance, vendor-mandated).

What's a typical SaaS stack waste rate?

Industry benchmarks put it at 30-50% across mid-market stacks. Companies past 100 tools usually clock 50%+ waste.
