Share of a Claude plan's weekly capacity

One “long chat thread (30 turns on a 50k-token context)” as a share of each Claude plan's weekly capacity, computed by calc.js (task cost ÷ weekly capacity).

PlanWeekly capacityLowLikelyHigh

Ranges were drafted at an Opus-class list price of about $5 per M input and $25 per M output tokens (Sonnet about 0.6x, Haiku about 0.2x). Re-checked 20 Oct 2026: Claude Opus 5.5 lists at $4 / $20 per M (claude.com/pricing), about 20% lower, so the high ends are conservative for Opus 5.5. On GitHub Copilot plans the calculator rescales every row to the chosen model's per-token rate published by GitHub (see methodology).
