How Much Does a Kubernetes Cluster Cost Per Month
Kubernetes cluster costs are often misunderstood because the total monthly bill includes node compute, control plane fees (on managed services), persistent storage, load balancers, and egress traffic. A three-node cluster is the production minimum for high availability - single-node clusters are for development only.
Price ranges by tier
A minimal self-managed three-node Kubernetes cluster on budget cloud VPS starts at EUR 45-90 per month for the nodes themselves. You manage etcd, the API server, and all control plane components. Mid-range clusters with dedicated vCPUs, adequate RAM per node (8-16GB per worker), and NVMe storage typically cost EUR 150-400 per month. Enterprise clusters with high-memory nodes, dedicated hardware, and 24/7 managed support can exceed EUR 1,000 per month.
Managed Kubernetes changes the math. You pay a control plane fee on top of node costs. AWS EKS charges USD 0.10 per hour per cluster, adding roughly USD 73 per month before a single node runs. DigitalOcean Kubernetes includes the control plane for free but nodes are priced at a premium. For European deployments, providers like Hetzner and DCXV offer self-managed or lightly managed options with no control plane surcharge.
What drives the cost
The primary cost drivers are node count and size, persistent volume storage class and IOPS, load balancer count (each typically costs EUR 5-20 per month), egress traffic beyond the included allocation, and managed control plane fees. A production Kubernetes cluster typically needs at least 3 worker nodes for pod scheduling redundancy. Adding a dedicated node pool for system workloads adds further cost.
Ingress controllers, cert-manager, monitoring stacks (Prometheus, Grafana), and log aggregation all consume node resources. Sizing nodes too small leads to over-provisioning in node count, which raises costs. Sizing too large means paying for unused RAM and CPU capacity.

Hidden costs to watch for
Load balancers are the most frequently overlooked cost. Each Kubernetes LoadBalancer service creates a cloud load balancer billed separately. A cluster with five externally exposed services can add EUR 50-100 per month in load balancer fees alone. Persistent volumes are billed by provisioned size, not used size. Cluster autoscaler can trigger unexpected node provisioning during traffic spikes. Egress charges apply when pods communicate across availability zones or to external networks on some providers.
