Calculator Inputs
This form uses a three-column layout on large screens, two columns on smaller screens, and one column on mobile devices.
Example Data Table
Use this sample table to compare different cluster shapes and spending profiles.
| Cluster | Nodes | vCPU/Node | RAM/Node (GB) | Egress (GB) | Monthly Total | Annual Total |
|---|---|---|---|---|---|---|
| Dev Sandbox | 2 | 2 | 8 | 150 | USD 328.40 | USD 3,940.80 |
| Staging Platform | 4 | 4 | 16 | 600 | USD 1,142.35 | USD 13,708.20 |
| Production HA | 8 | 8 | 32 | 2400 | USD 4,896.90 | USD 58,762.80 |
Formula Used
CPU Cost = Nodes × vCPU Per Node × CPU Hourly Rate × Billing Hours
Memory Cost = Nodes × RAM Per Node × RAM Hourly Rate × Billing Hours
GPU Cost = Nodes × GPU Per Node × GPU Hourly Rate × Billing Hours
Storage Cost = Nodes × Storage Per Node × Storage Monthly Rate
Network Cost = Monthly Egress GB × Egress Rate
Load Balancer Cost = Load Balancer Count × Load Balancer Monthly Rate
Base Infrastructure = CPU + Memory + GPU + Storage + Control Plane + Network + Load Balancers + Ops Tooling
Overhead Cost = Base Infrastructure × Overhead Percent
Discount Amount = (Base Infrastructure + Overhead Cost) × Discount Percent
Tax Amount = (Base Infrastructure + Overhead Cost − Discount Amount) × Tax Percent
Monthly Total = Base Infrastructure + Overhead Cost − Discount Amount + Tax Amount
Annual Total = Monthly Total × 12
Productive Spend = Monthly Total × Utilization Percent
Idle Spend = Monthly Total − Productive Spend

Frequently Asked Questions
1. What does this Kubernetes cost calculator estimate?
It estimates monthly and annual cluster spend using worker nodes, compute pricing, storage, traffic, platform overhead, discounts, tax, and operational tooling costs.
2. Does it include control plane charges?
Yes. You can enter a fixed monthly control plane charge, which is common for managed Kubernetes services that separate cluster management from worker node billing.
3. Why is utilization included?
Utilization helps estimate productive spend versus idle spend. It does not change raw infrastructure pricing unless you also model rightsizing through discount or reduced resource inputs.
4. Can I model GPU workloads?
Yes. Enter GPUs per node and the GPU hourly rate. The calculator adds GPU cost to the monthly infrastructure total automatically.
5. What is included in ops tooling?
Ops tooling combines monitoring, backup, support, and platform tools. Examples include observability services, backup software, managed support plans, and ingress or service mesh add-ons.
6. How should I choose billing hours?
A common monthly value is 730 hours. Use a different number when you model partial-month workloads, scheduled shutdowns, or custom billing assumptions.
7. Does the chart show discounts too?
Yes. The Plotly bar chart includes the discount as a negative value so you can see how savings offset gross monthly cost components.
8. Can this calculator help with rightsizing?
Yes. Change node counts, resource sizes, utilization, and discount assumptions to compare scenarios and identify waste before resizing workloads or changing purchase commitments.
