Developer Gotcha: Stopped Storage Billing

When you click Stop Instance on Amazon Web Services (AWS EC2 AI), your GPU compute charge stops, but the 200GB disk volume continues billing 24/7 ($20.00/mo) until you terminate the volume. Always backup checkpoints to HuggingFace or S3 before terminating.

Estimated Total Monthly BillSpot Rate

$78.74 / month

Hourly run-rate: $0.32/hr compute + $0.0274/hr disk

Active GPU (183 hrs):$58.74

Persistent Disk (200GB 24/7):$20.00

You save ~$167/mo (68%) vs AWS EC2

Equivalent cloud capacity on AWS would cost approx. $245/mo for 6h daily runtime.

The Stopped Storage Fee Gotcha on Amazon Web Services (AWS EC2 AI)

When you stop an instance on Amazon Web Services (AWS EC2 AI), your hourly GPU compute charge drops to $0.00/hr immediately. However, any persistent disk volume (where your ComfyUI models, LoRAs, or Conda environments live) remains reserved on physical NVMe drives and continues accruing storage billing 24 hours a day, 7 days a week ($0.08 - $0.125/GB/month (EBS gp3)).
