Amazon EKS makes it easy to run Kubernetes without managing the control plane, but pricing isn’t always straightforward. Between EC2, Fargate, storage, data transfer, and add-on services, your monthly bill can vary widely depending on how you deploy and scale your workloads.

This guide breaks down how EKS pricing works—component by component—so you can understand where costs come from and how to plan accordingly. Whether you’re building a dev cluster or scaling production workloads, you’ll get a clear view of what to expect and how to avoid surprises.

EKS Pricing Components

EKS pricing is made up of several components. Some are fixed, like the control plane fee, while others depend on how your workloads run—like node type, storage, and network traffic.

Here’s a breakdown:

Component Price Notes
Control Plane $0.10 per hour per cluster ~$72/month per cluster
EC2 Nodes Varies by instance type and pricing model On-demand, Reserved, Spot
Fargate Pods $0.04048 per vCPU-sec + $0.004445 per GB-sec Charged per running pod
EBS Storage $0.10 per GB-month Snapshot storage billed separately
Load Balancer $0.0225/hr + $0.008 per LCU-hr For ALB/NLB used by services or Ingress
Data Transfer $0.01–$0.09 per GB outbound Intra-AZ is free; cross-AZ and internet cost extra

Deployment Models and How They Affect Pricing

EKS is flexible in where and how it runs—but that flexibility comes with very different cost implications.

Here are the four main models, and how they impact what you pay for.

Model Where It Runs What You Pay For When to Use
EKS on EC2 Your managed EC2 nodes EC2 + EKS control plane + storage + network Best when you want control and lower long-term costs
EKS on Fargate AWS-managed Fargate vCPU & memory per pod-second + EKS control plane Great for bursty workloads, short-lived jobs
EKS on Outposts On-prem AWS hardware Outposts infra (custom) + EKS control plane + network Hybrid or regulatory environments
EKS Anywhere On your own infra No EKS infra cost; optional support contract Self-managed K8s with EKS tooling

Cost Behavior by Model

  • EC2: You choose the instance types, pricing model (on-demand, spot, reserved), and node count. High control, higher management.
  • Fargate: You don’t manage nodes, but costs scale linearly with pod usage. Easy to overpay for idle or underused resources.
  • Outposts: Enterprise hybrid model with custom pricing, not typically cost-efficient for small teams.
  • Anywhere: No AWS charges, but you manage everything and lose cloud-native elasticity unless combined with autoscalers.

EKS Pricing Examples

Understanding pricing components is one thing—seeing how they add up in practice is another. Below are real-world examples to illustrate how EKS costs can vary based on workload type, node selection, and deployment model.

Example 1: Small Dev Cluster on EC2

Let’s assume:

  • 1 control plane
  • 2 × t3.medium EC2 instances (2 vCPU, 4 GB RAM)
  • 100 GB gp2 EBS
  • 1 ALB
Component Usage Monthly Cost
Control Plane 730 hours $72.00
EC2 Nodes 2 × t3.medium ~$100
EBS Storage 100 GB $10.00
ALB 1 load balancer ~$16
Total ~$198/month

This is a baseline development setup with no autoscaling, no Spot pricing, and minimal network traffic.

Example 2: Burstable Job on Fargate

Let’s say you have a batch job that runs once per day, using:

  • 2 vCPU and 4 GB memory
  • 30 minutes/day

Fargate billing (rounded):

  • vCPU: 2 vCPU × 1800 sec × $0.04048 = $0.1457/day
  • Memory: 4 GB × 1800 sec × $0.004445 = $0.0319/day
  • Total: $0.18/day = $5.40/month

Fargate shines here—you only pay for the compute time your job actually runs. For sporadic workloads, it’s far more cost-effective than always-on EC2 instances.

EC2 vs Fargate: Cost Snapshot

Scenario EC2 Fargate
Always-on workload More efficient at scale More expensive over time
Bursty or short-lived Wasteful unless auto-scaled Pay only for runtime
Management overhead You manage nodes AWS handles node lifecycle
Cost flexibility Reserved/Spot savings possible No reservations, fixed pricing

How to Estimate EKS Costs Accurately

Before launching a new cluster, it’s worth modeling your expected spend—especially since EKS pricing spans multiple services (EC2, storage, networking, etc.).

What You Need to Account For

To build an accurate estimate, factor in:

  • Number and type of worker nodes (or Fargate usage)
  • Storage volumes (per workload, including replicas)
  • Load balancers and network traffic patterns
  • Logging, monitoring, and any add-on AWS services
  • Region-specific pricing differences
Tool What It Does Well Limitations
AWS Pricing Calculator Official, supports EC2 + EKS + EBS Manual, time-consuming
DevZero Provides spend + utilization dashboards Works with live clusters
Spreadsheets Quick, flexible for rough forecasts Easy to miss hidden costs

Pro tip

Don’t just look at monthly totals—use Kubernetes cost monitoring to track per-pod or per-team costs and catch inefficiencies early. Idle EC2 nodes, oversized requests, or underutilized volumes are some of the most common budget leaks in EKS.

To stay on top of these patterns, many teams use Kubernetes cost optimization tools that provide granular visibility and automate resource tuning based on real usage—helping prevent waste before it impacts your bill.

Frequently Asked Questions

Is Amazon EKS free?

No. You pay $0.10/hour for each EKS cluster you create. That’s roughly $72/month, even if no pods are running.

What’s the cheapest way to run EKS?

Use a single EKS cluster with Spot EC2 nodes, limit persistent storage, and avoid unnecessary load balancers. You can also schedule workloads to shut down during off-hours.

How is Fargate pricing different from EC2?

Fargate bills per second based on vCPU and memory per pod. EC2 bills per instance, regardless of how much of it you actually use.

Is there a free tier for EKS?

Not for the control plane. But if you use the AWS Free Tier, you can test workloads on small EC2 instances or low-cost Fargate tasks—though it won’t cover full EKS operation.

Does EKS pricing vary by region?

Yes. EC2, Fargate, EBS, and data transfer prices can vary significantly between regions. Always verify rates in the AWS pricing calculator.

Conclusion

EKS pricing isn’t complicated—but it is fragmented. Your total cost depends on how you deploy, scale, and configure your infrastructure across multiple AWS services.

The key is to:

  • Know what you’re being charged for (control plane, compute, storage, networking)
  • Choose the right deployment model (EC2 vs Fargate vs Anywhere)
  • Estimate costs early and monitor them continuously

When you’re running production workloads or managing infrastructure across multiple teams, every overprovisioned pod or idle node chips away at your budget. If you’re looking to reduce cloud waste and run your EKS clusters more efficiently, check out our full EKS Cost Optimization Guide.
