Chargeback & Cost Allocation

K8Cost provides detailed cost attribution by team, namespace, label, and service -- giving platform teams and FinOps practitioners the data they need for internal chargeback and showback reporting.

What It Does​

The chargeback system allocates cluster costs down to individual workloads based on resource consumption. It answers the question every platform team gets asked: "How much is each team actually spending on infrastructure?"

K8Cost calculates costs using your cloud provider's actual pricing (or custom rates for on-premise), then attributes them based on resource requests and actual usage.

Allocation Methods​

  • Namespace-based -- The simplest model. Each namespace represents a team or service, and costs are allocated based on aggregate resource consumption within the namespace.
  • Label-based -- Use Kubernetes labels (e.g., team=payments, env=production, cost-center=engineering) to group workloads across namespaces for more flexible allocation.
  • Shared cost pools -- Infrastructure costs that do not belong to a single team (monitoring, ingress controllers, system namespaces) can be distributed proportionally or evenly across consuming teams.

Key Capabilities​

  • Real-time cost breakdown by namespace, label selector, or custom grouping
  • Shared cost distribution -- Define shared cost pools for cluster-wide services and allocate them using proportional, even, or weighted splits
  • Export to CSV/JSON -- Download cost data for import into your finance or FinOps tools
  • Historical comparison -- Compare cost allocation across time periods to track team-level spending trends
  • Multi-cluster aggregation -- View chargeback data across all clusters or drill down to individual clusters

Common Use Cases​

  • Engineering team showback -- Show each team how much their services cost without creating formal billing relationships
  • Business unit chargeback -- Allocate infrastructure costs to business units for P&L reporting
  • Environment cost tracking -- Compare spend across production, staging, and development environments
  • Project-based attribution -- Use labels to track costs for specific projects or initiatives across multiple namespaces
