I also ran a single instance k3s node on my personal $8/mo 3gb vps, and it took up around 400MB. Ran some workloads, a postgres operator. Ingreds via traefik on the node. I think my overhead was like $1.20/mo. Did I have fancy HA? No. But it was an easy way to manage workloads & learn skills. Works fine.

You're paying 4x as much for your self-managed cluster as I am for a vendor managed cluster. I have a single-node digital ocean cluster without a load balancer.

Maybe I'm ignorant, but why would you pay $1200/year for the compute/storage/ram equivalent of a 5 year old iPhone?
Overhead is as follows (/month):
1 x load balancer: $20
3 x master servers: 4GB RAM, 2 CPU, 15 GB SSD: 3 * $20 = $60
also on every worker server around 15% of RAM is dedicated to kubernetes pods (kubelet). So slightly higher price for RAM and CPU.
So basically overhead is like $100/month. Or $50/month with one master server which is not very reliable but acceptable for small workloads. If your project runs on $5/months VPS, Kubernetes is pure overhead. If you're paying $500/month, Kubernetes is something to consider.
