Modeled, not billed. GPU is split by GPU pod-hours and CPU by notebook memory requested, so idle pre-warm time lands on the hubs that used those nodes. The always-on base (core-pool, disks, cluster fees) is shared by every hub and is not split here. Per user is this period's cost over the term's users, so it reads high early in a term.

Year over year#

CloudBank only. Term users are accounts whose last activity fell in that term, so someone active in both fall and spring counts in spring.

Net of credits, from the CloudBank billing export. Mar 2024 – Aug 2025 is not in the export, so those months show as –. The current month fills in as the export catches up.

The charts are modeled figures. Cost is measured node-hours × Cloud Billing Catalog list price, which is the only figure for the last 1–2 days. Billed figures from the billing export are under Modeled vs billed. Sustained-use discounts are not modeled (the real bill is lower); snapshot uploads, egress, logging and monitoring are not modeled (higher). Estimated components: gke-cluster-fee, load-balancers, oss-cluster, snapshots, storage.

Modeled vs billed#

Billed figures come from CloudBank's billing export, net of sustained-use and other credits. The export runs 1–2 days behind, so recent days show as pending and the model is the only figure for them.

Always-on base#

core-pool + oss-cluster + GKE cluster fees + persistent storage. This is the number to quote when asked what CloudBank costs to simply exist.

$72.05 / day   $2,162 / month

58% of total spend over the last 7 days.

What makes it up

Component$/day$/monthshare
core-pool nodes$32.43$97345%
Persistent disk (home dirs + other) modeled$26.54$79637%
oss-cluster (no Prometheus — modeled) modeled$6.76$2039%

Only the top line is measured node-hours. Everything below it is provisioned capacity or a flat fee — it costs the same at 3am on a Sunday. Not included: internet egress, Cloud Logging and Monitoring, and snapshot uploads. Their billed amounts are under Modeled vs billed.
