What is AI Cost Attribution?
AI Cost Attribution is the practice of tracking and assigning the full cost of AI features to specific products, features, customers, or business units.
AI Cost Attribution is the practice of tracking and assigning the full cost of AI features to specific products, features, customers, or business units. Unlike traditional software (near-zero marginal cost), AI features have significant variable costs that must be attributed accurately for economic decision-making.
Costs to attribute: LLM API fees, embedding generation, vector database queries, retrieval pipeline compute, post-processing, monitoring, error handling and retry costs, prompt engineering time, model fine-tuning, and human-in-the-loop review.
Without proper cost attribution, organizations cannot calculate AI unit economics, identify margin-negative features, or make informed build-vs-buy decisions.
Why It Matters
Most AI product failures are economic, not technical. Without cost attribution, teams build impressive AI features without knowing that each user interaction costs more than the revenue it generates.
How to Measure
Tag every AI API call with feature ID, customer ID, and model version. Aggregate costs by feature, customer, and time period. Compare to feature-level revenue.
Frequently Asked Questions
How do you implement AI cost attribution?
Use API middleware that tags every inference request with metadata (feature, customer, model). Aggregate in a cost dashboard. The AUEB calculator at richardewing.io/tools/aueb helps model these economics.
