LLM cost tracking for CFOs.
A finance guide · July 26, 2026
Tracking LLM costs is not about adding another dashboard. It is about giving finance and product a shared source of truth so they can decide together what is worth spending on.
1. Tag everything from day one
The foundation of tracking is attribution. Every request should carry at least: team, project, feature, model, provider, and environment. Without tags, the provider invoice is a black box. With tags, you can slice spend by product line, customer segment, or experiment.
2. Build the right dashboard
A useful LLM cost dashboard answers four questions at a glance:
- What are we spending? — total and by period.
- Who is driving it? — team, feature, and model breakdown.
- Is it getting more or less efficient? — cost per task over time.
- Where are the outliers? — spikes, anomalies, and new endpoints.
3. Track the metrics that matter
Volume metrics such as tokens and requests are useful, but outcome metrics are better. Cost per resolved ticket, cost per accepted code suggestion, and cost per completed workflow tell you whether the spend is productive.
4. Reconcile to the invoice
Internal dashboards drift. Reconcile them to the provider invoice monthly. Pay special attention to cache-read tokens, retries, and fallback calls, which dashboards often under-count.
5. Review weekly, forecast monthly
Weekly reviews catch spikes and experiments early. Monthly forecasts keep the board informed. The best teams combine both: weekly operational reviews for action, monthly summaries for planning.
