SaaS stack TCO & overlap
Choose the capabilities your team needs. The model searches a frozen Notion, Slack and Zapier reference set and returns the lowest modeled monthly stack that covers them.
Independent tool: calculations run locally in your browser; tracked commercial links remain separately disclosed when present.
What this model actually does
It evaluates at most one plan from each vendor family and requires the selected combination to cover every checked capability. Per-member plans scale with the team size; Zapier reference prices are modeled as published starting monthly plan prices.
Notion Plus US$10/member/month and Business US$20 on the displayed yearly USD view; Slack Pro US$7.25/active user/month annually and Business+ US$15; Zapier Professional from US$19.99/month annually and Team from US$69/month.
What it does not prove
The lowest modeled cost is not automatically the best product choice. Workflow depth, migration cost, data portability, support quality, tax, currency conversion, promotions, usage tiers and unmodeled capabilities can change the real decision.
Verify current vendor pricing and packaging before acting. This frozen snapshot exists so the calculation can be reproduced and audited.
