Run the numbers: cost per completed task

Every value below is yours to set — the defaults are only illustrations. This is the math to pressure-test any vendor's pricing against question 5.
Your numbers
Human cost per task
Human cost per month
Agent effective cost / completed task*
Agent cost per month
estimated monthly difference
*Effective cost = vendor price + the platform fee spread over your volume + the human minutes spent reworking failed tasks. If a vendor cannot walk you through this math for your volume, that is the question-5 red flag. No benchmarks are baked in; the output is only as honest as your inputs.
