The Same Claude Code Work Costs Up to 40x More on Enterprise Per-Token Billing Than on a Subscription Seat — and 82% of That Is Cache

Jacek Migdal's August 11, 2026 breakdown compares Claude Max at $100/month and Team at $200/month against per-token rates of $5/$25 per million for Opus 5 and $10/$50 for Fable 5, with cache reads at 0.1x input and cache writes at 1.25–2x. A SemiAnalysis test of a $200/month 20x-multiplier user found roughly $8,000 in API-equivalent cost — the 40x figure — alongside earlier measurements of 12x (Simon Willison), 15x, and 21x gaps. The load-bearing detail for anyone budgeting agent work: 82% of the API-equivalent cost was cache-related, because every API call re-reads the whole conversation.
