A CFO asks for a 'unit economics dashboard'. What does 'unit economics' mean in cloud cost reporting?
Unit economics connects infrastructure cost to business metrics: 'we spend $0.003 per active user per month' or 'our cost per processed order is $0.12'. This translates cloud spend into business language that non-technical stakeholders can use for decisions.

A FinOps report states 'cost per active user increased from $0.45 to $0.67'. Why is this metric more useful than total cloud spend?
Cost per active user is a normalised efficiency metric. Total cloud spend can grow as users grow (expected). But if cost per user also grows, it means the product is becoming less efficient — a warning sign regardless of overall revenue.

When a report shows the 'cost vs. revenue ratio is 18%', what does this communicate?
The cost-to-revenue ratio (also called infrastructure as a percentage of revenue) is a key SaaS efficiency metric. Industry benchmarks vary, but investors and CFOs use this to assess whether infrastructure costs are scaling efficiently with revenue growth.

What is 'engineering cost allocation by service' in FinOps reporting?
Cost allocation tags cloud resources to teams, services, or features so engineering teams can see exactly what their service costs. This drives accountability — teams that see 'our service costs $8,000/month' are motivated to optimise.

A budget report says 'we overspent the cloud budget by 23% this month'. How should this be communicated in a FinOps review?
FinOps budget overrun communication should include: the amount and percentage over budget, the root cause (e.g. 'unplanned traffic spike from marketing campaign'), whether it's a one-time event or recurring, and concrete steps to avoid recurrence — not just the number.
