How much does an idle m7i.4xlarge cost on AWS?
An m7i.4xlarge billed on-demand and left running around the clock costs about $589/mo at its cheapest listed region (us-east-1). Scheduling it off outside business hours cuts that to roughly $175/mo — a $413/mo saving.

|---|---|---|
| Running 24/7 | $589/mo | baseline |

Assumes a 730-hour month at on-demand list price. Actual savings depend on when the instance is actually used.
About the m7i family
M7i is the latest-generation Intel Sapphire Rapids general-purpose instance, with DDR5 memory and improved networking over M6i/M5. It's increasingly the default pick for new staging and integration environments that want current-generation performance without going compute- or memory-optimized. Being newest also means it's the least likely to have inherited an old shutdown schedule, so these environments frequently start life running 24/7 by default.
Regional pricing varies: m7i.4xlarge runs $0.8064/hr in us-east-1, the cheapest region priced here, versus $1.2852/hr in sa-east-1, the priciest — a 37% spread across regions for the identical instance type.
Common questions
How much does an idle m7i.4xlarge cost per month?
At the cheapest listed region (us-east-1), an m7i.4xlarge costs $0.8064/hr, or about $589/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 $413/mo (70%) versus running 24/7. A lighter schedule — on around the clock on weekdays, off on weekends — still saves about $168/mo (29%).
Do dev environments need the newest generation like m7i?
The honest argument is parity with production rather than raw need: performance-test rigs should match prod hardware, and m7i increasingly is prod hardware. For everything else, an older generation on a tight schedule is cheaper than the newest one running around the clock.

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.
