Formula
Base tokens = transactions × tokens per transaction + shared context
Budget = base tokens × (1 + retry rate ÷ 100) × (1 + headroom ÷ 100)
What the result means
This budget estimates model-token demand for a fraud-screening batch. Rechecks and headroom are explicit so operations teams can see why the budget exceeds the nominal transaction payload.
