Kubernetes Resource Calculator

Calculate Kubernetes CPU and memory requests, limits, container totals, pod totals, and workload resource usage from YAML directly in your browser.

Paste a Kubernetes Pod, Deployment, StatefulSet, DaemonSet, Job, or CronJob YAML file to calculate CPU and memory requests and limits.

Calculating Kubernetes CPU and Memory Requests

Kubernetes resource requests and limits are easy to miss when a YAML file has many containers, sidecars, replicas, and workloads. A small resource value can look harmless in one container but become much larger after replicas are counted.

This Kubernetes Resource Calculator reads CPU and memory requests and limits from Kubernetes YAML and calculates totals by container and workload. It is useful before deployments, cluster sizing checks, namespace reviews, and cost or capacity discussions.

Checking Resource Totals From YAML

  1. Paste a Kubernetes workload YAML file into the input box.
  2. Choose whether replica counts should be included.
  3. Select CPU and memory display units.
  4. Review total requests, limits, workloads, and containers.
  5. Copy the summary, JSON, or table output for notes or review.

Common Kubernetes Resource Calculator Use Cases

  • Estimating CPU and memory usage before deploying a workload.
  • Checking total requests and limits after replica counts.
  • Reviewing sidecar containers that add hidden resource usage.
  • Finding containers with missing requests or limits.
  • Preparing capacity notes for staging or production clusters.
  • Comparing resource values during Kubernetes YAML reviews.

Example Kubernetes Resources

resources:
  requests:
    cpu: "250m"
    memory: "256Mi"
  limits:
    cpu: "500m"
    memory: "512Mi"

Requests, Limits, and Real Cluster Capacity

Requests are used by Kubernetes scheduling to reserve capacity. Limits control the maximum resources a container can use. Both matter, but they answer different questions.

This calculator is a browser-side estimate from the YAML you paste. Always review the final values with your actual cluster settings, namespaces, autoscaling rules, and deployment process.

Frequently Asked Questions

What does a Kubernetes Resource Calculator do?

It reads Kubernetes YAML and calculates CPU and memory requests and limits across containers and workloads.

Does this include replica counts?

Yes. Replica counts are included by default for workloads like Deployments and StatefulSets. You can turn that off if you want per-pod values only.

Can this parse CPU values like 250m?

Yes. CPU values such as 250m, 0.5, and 1 are converted into millicores or cores for output.

Can this parse memory values like Mi and Gi?

Yes. Memory values such as Mi, Gi, Ki, M, and G are converted into Mi or Gi for output.

Is my Kubernetes YAML uploaded anywhere?

No. Calculation happens directly in your browser, and your YAML is not uploaded to a server.
