  "canonical_url": "https://www.unitcostai.com/tools/codex-vs-claude-code-cost",
  "formula": "usage_priced_monthly_spend_usd = monthly_active_developers * api_equivalent_cost_per_active_developer_month; plan_only_monthly_spend_usd = billed_seats * monthly_seat_price_usd; plan_plus_overflow_monthly_spend_usd = billed_seats * monthly_seat_price_usd + monthly_active_developers * overflow_units_per_active_developer_month * overflow_unit_price_usd",
  "assumptions": [
    "Usage-priced baseline is optional; when enabled, usage-priced mode has no fixed seat assumption and uses your own API-equivalent baseline",
    "Plan-plus-overflow only uses explicit user-entered overflow units and overage unit prices",
    "Soft limits and included allowances stay qualitative unless deterministic overage schedules are published"
  ],
  "example": "If 8 active developers put Codex seat spend at $320/mo and Claude seat spend at $400/mo, Codex leads in plan-only mode; enabling a usage baseline then shows how either lane compares to current usage.",
