How much does an idle c2-standard-4 cost on Google Cloud?
A c2-standard-4 billed on-demand and left running around the clock costs about $152/mo at its cheapest listed region (us-central1). Scheduling it off outside business hours cuts that to roughly $45/mo — a $107/mo saving.

About the c2 family
C2 is GCP's compute-optimized Intel Cascade Lake family, built for the highest sustained per-core performance — HPC, high-performance gaming servers, ad serving, and media transcoding. Test and staging rigs for these workloads need that same CPU ceiling during a run, then go completely idle between runs or overnight. Because C2 hourly rates are high, an idle C2 box is one of the more expensive ways to leave a dev environment running unattended.
Regional pricing varies: c2-standard-4 runs $0.2088/hr in us-central1, the cheapest region priced here, versus $0.2690/hr in europe-west2, the priciest — a 22% spread across regions for the identical instance type.
The next size up in the same family, c2-standard-8 (8 vCPU / 32 GB RAM), costs about $305/mo running 24/7 at its cheapest region — roughly 100% more than c2-standard-4's ~$152/mo — for 2x the vCPU.
Common questions
How much does an idle c2-standard-4 cost per month?
At the cheapest listed region (us-central1), a c2-standard-4 costs $0.2088/hr, or about $152/mo if it runs 24/7. That's the on-demand list price — an idle instance costs exactly the same as a busy one, since cloud billing doesn't know the difference.
How much can I save by scheduling it off outside work hours?
Restricting it to business hours only (10×5) saves about $107/mo (70%) versus running 24/7. A lighter schedule — on around the clock on weekdays, off on weekends — still saves about $44/mo (29%).
What makes idle c2 instances especially costly?
c2 pairs the highest sustained per-core performance in GCP with a correspondingly high hourly rate, and its typical workloads — benchmarks, simulations, transcoding — are bursty by nature. That combination makes the gap between "used hard for two hours" and "provisioned all week" wider than on any general-purpose family.

Stop paying for idle Google Cloud servers
Idlefy runs a free audit of your fleet, then flips dev servers to stopped-by-default: lease one when you need it, and
when the lease ends it shuts itself off — stop, not terminate, persistent disks intact. Timers are set by your team, never
guessed, and Idlefy only manages instances tagged idlefy=enabled — on AWS that boundary is enforced by the IAM policy itself.
Prices are on-demand list price for standard instances and exclude storage, network, data transfer, and any negotiated or volume discounts. Actual bills vary by usage and account-level pricing. Prices as of 2026-07-20. Spot figures are indicative — AWS values are derived from AWS's published typical savings vs on-demand for the region; GCP values are the listed Spot price. Spot capacity can be reclaimed by the provider. Stopping preserves EBS and persistent-disk volumes; data on local instance-store or local-SSD drives does not survive a stop.
