    Formula, assumptions and sources

    Cost per task = (input per call + output per call) × calls × attempts × modifiers + rework (minutes/60 × €/h × 1.08 USD/EUR).

    Modifiers: batch × 0.5, US residency × 1.1, router × 1.055. Input per call factors cache at 0.1.

    Prices are vendor list prices as of 21 July 2026, without discounts. Among the presets, only the 3,700 tokens for a support conversation is empirically documented (source: Anthropic documentation). All other presets are plausible example values, not measurements.
