How much does an idle m6i.large cost on AWS?
An m6i.large billed on-demand and left running around the clock costs about $70/mo at its cheapest listed region (us-east-1). Scheduling it off outside business hours cuts that to roughly $21/mo — a $49/mo saving.

About the m6i family
M6i is the sixth-generation Intel Ice Lake refresh of the general-purpose line, with higher per-core performance and more consistent latency than M5 at a similar price point. Teams upgrade existing M5 fleets to M6i for staging and QA environments to get closer parity with newer production hardware. The upgrade rarely comes with a corresponding schedule review, so the same idle nights-and-weekends pattern just moves to slightly more expensive hardware.
Regional pricing varies: m6i.large runs $0.0960/hr in us-east-1, the cheapest region priced here, versus $0.1530/hr in sa-east-1, the priciest — a 37% spread across regions for the identical instance type.
The next size up in the same family, m6i.xlarge (4 vCPU / 16 GB RAM), costs about $140/mo running 24/7 at its cheapest region — roughly 100% more than m6i.large's ~$70/mo — for 2x the vCPU.
Common questions
How much does an idle m6i.large cost per month?
At the cheapest listed region (us-east-1), an m6i.large costs $0.0960/hr, or about $70/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 $49/mo (70%) versus running 24/7. A lighter schedule — on around the clock on weekdays, off on weekends — still saves about $20/mo (29%).
Is m6i worth it over m5 for dev and staging?
If you are provisioning fresh, yes — newer Ice Lake cores at a comparable price. Upgrading an existing, quiet m5 environment purely for speed rarely pays back, since dev boxes spend most of their week idle anyway. Match production hardware where parity matters — performance testing — and schedule everything else off.

Stop paying for idle AWS 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 Linux 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.
