What decision does this help answer?
Could an agent loop exceed the spend limit before a human notices?
Calculation and methodology
Calculate a per-iteration upper cost from input/output tokens and explicit per-million token rates, then add paid tool charges. Multiply by allowed iterations, concurrent runs and daily job counts for a worst-case monthly envelope. Compare to a selected spend guard and recommend hard caps rather than relying on a prompt to stop.
Limitations and responsible interpretation
Worst-case assumptions intentionally overstate some workflows and understate unpredictable external provider charges. Real token usage, retry behavior and queueing must be observed. Enforce caps in infrastructure and payment limits rather than in model text alone.
