Workday Ledger · 2026-05-23 consultance.ai

Three Hundred *Thousand.*

That's the median annual Workday HCM bill for a 500-employee company once you stack seats, Illuminate AI, partner deploy hours, custom report dev, and the bolt-on HR SaaS nobody talks about. This calculator shows what survives when Claude replaces the layer Workday charges most for.

A trade-off ledger, not a sales pitch. Punch in your numbers. The tape recalculates live.
