Resource Cost Estimator

Overview

You pass a resource list and a price table you already trust; we multiply quantities, replicas, and hours with BigDecimal arithmetic and return line-item totals as decimal strings (never JSON numbers). Kubernetes quantities such as 512Mi or 500m use the same parser as devops.validate_kubernetes_yaml. We do not look up cloud prices or convert currencies. Do not use this when you need live pricing APIs or discount modelling.

Cost math done in floating point silently loses cents, and mixed currencies are worse. We keep every step in decimal strings you can audit, and every price comes from the table you send rather than any pricing feed of ours.

When to use it

Scope

Non-goals

• Does not look up cloud prices

Recommended use cases

• What-if cost from a known internal price sheet
• Agreeing Kubernetes quantity meanings with devops.validate_kubernetes_yaml

Avoid for

• Live cloud pricing or FX conversion
• Invoice reconciliation against a cloud provider bill
