Cost Estimation & ROI
Estimate cost per task: input tokens + output tokens × price, plus embeddings, vector storage, hosting and monitoring. Multiply by expected volume per month.
Estimate value: time saved × hourly cost, error reduction, faster response or new revenue. ROI compares this value with build and run costs.
Present ranges and assumptions clearly, and plan a pilot that measures real numbers before full rollout.
Key points
- Cost = tokens × price × volume + infra
- Value = time saved, errors avoided, revenue
- State assumptions as ranges
- Prove ROI with a measured pilot
