Hourly or Monthly Mac Rental: Find Your Break-Even

Monthly flat rates win past roughly a day of use; hourly only pays for rare sessions

If you need a Mac for CI, nightly builds, or anything approaching daily work, a monthly flat plan is almost always cheaper than hourly on-demand. Hourly wins only when usage is genuinely sparse — a single short session per month — and even then the 24-hour minimum allocation on AWS Mac hosts narrows the gap considerably. The math below is a single formula applied to three usage schedules, with current prices read from each vendor's own page.

How hourly Mac compute actually bills

The main public hourly source is AWS EC2 Mac dedicated hosts. AWS bills per second, with a 24-hour minimum allocation per host tied to the Apple macOS SLA (AWS EC2 Mac, EC2 Dedicated Hosts pricing). A 10-minute run and a 23-hour run on the same allocation cost the same.

On-demand rates (US East, N. Virginia, per host-hour) from the AWS static pricing feed dedicatedhost-ondemand.json, read 2026-11-10:

Each row is a whole dedicated host (all cores, all RAM). Storage and network transfer are extra. Savings Plans discounts exist but the exact dollar amount depends on term and commitment and must be modelled in the AWS calculator; 730 h is a normalised month, not what you will see on any actual invoice.

Monthly flat-rate plans with the vendor's own primary page beside each price:

Notes on these rows. CloudMac's 256 GB row is listed as "Reserve now"; the 512 GB and 1 TB rows are "Fully reserved, next allocation not scheduled" — ask before counting on them. MacStadium's pricing page shows monthly or annual terms and publishes a 99.99% uptime commitment with support and network included; multi-year terms are via sales. Figment's $95 entry is an M-series starting price, not an M4/16 GB equivalent; exact chip, RAM and disk are confirmed in the quote. The $29 Figment VM is a virtual Intel macOS environment on Linux/KVM — it runs compatible Intel Xcode (Xcode 26 or earlier, per Apple's porting guidance at developer.apple.com) and can cross-compile and sign supported targets; it is not an Apple silicon machine, has no GPU acceleration or audio, and access is via the browser console and the VM's own desktop terminal.

The break-even formula

Let H = hourly rate ($/hr), M = monthly flat rate ($), h = hours used per month.

Hourly cost  = H × h
Monthly cost = M

Break-even:  H × h = M
             h*    = M / H

If your actual h > h*, the flat monthly plan is cheaper. If h < h*, hourly might be cheaper — but only after you account for the 24 h minimum per allocation.

Break-even hours against AWS M4 ($1.23/hr) and M2 ($0.878/hr):

These are entry-price comparisons, not equal-hardware comparisons. AWS rows are whole dedicated hosts; Figment's $29 VM is a virtual Intel environment; CloudMac and MacStadium are dedicated M4/M2 minis. Use the formula with whichever pair of prices applies to your real workload.

Three usage schedules, worked out

All AWS figures use the M4 on-demand rate of $1.23/hr. "Billed hours" accounts for the 24-hour minimum that applies each time you allocate a host.

A few honest conclusions from the table:

• Sprint: The 24 h minimum erases most of the per-hour advantage. One short AWS M4 session costs nearly the same as a whole month of Figment's $29 VM; pick based on whether you need ARM/M4 hardware or whether the Intel VM is sufficient for the task.
• Part-time: 80 continuous hours on AWS M4 is within pennies of CloudMac's monthly rate. If you need ARM, the flat plan is simpler; CloudMac's $999 annual prepay drops the effective monthly to $83.25.
• Continuous: Flat monthly wins decisively. At 176 h/mo you are also well past the break-even for every row in the table above.

Operational checks before you switch

• Allocation events reset the 24 h clock. Releasing and re-allocating a Mac host on AWS triggers another minimum. Keeping one host allocated across sparse sessions is often cheaper than allocating per-session.
• Idle time still bills on AWS. A build job that fires at 02:00 and runs for ten minutes still bills from the allocation moment, not just the active minutes.
• Storage and egress are separate on AWS. Flat plans from Figment, CloudMac and MacStadium bundle local disk; check each provider's egress/transfer terms if you push large artefacts off-host.
• Hardware class matters. Xcode 27 and visionOS require Apple silicon; Xcode 26 and earlier run on Intel and can cross-compile arm64. If you need M-series, do not break-even against the $29 Intel VM.
• Taxes and fees. Each offer states its own tax and fee treatment on checkout; confirm there rather than assuming.

A short migration path

Monthly flat → hourly (shrinking commitment):

1. Let the current flat plan run to renewal; no partial-month refund is assumed.
2. Allocate an AWS Mac Dedicated Host in the target region and confirm the 24 h minimum works for your session length.
3. Register your CI runner from the host's own terminal (outbound to your CI service) and run one real pipeline end-to-end.
4. Keep one month of overlap bills before cancelling the flat plan, then compare against the formula above.

Hourly → monthly flat (growing commitment):

1. Pull three months of AWS bills and compute average hours per month.
2. If average h exceeds the relevant h* for the plan you want, request the configuration quote at /mac-hosting/start. Figment's physical M-series plans currently collect requests until supply is confirmed; the $29 VM is the one entry that does not need the quote step.
3. Move the CI runner registration to the new host; verify a full build cycle before releasing the AWS host.

Choose the Figment plan

For intermittent workloads the $29 virtual Intel macOS plan is the lowest monthly entry in this comparison — less than one 24-hour AWS M4 minimum. For ARM or heavier builds, request a configuration quote and we will match a specific M-series machine to the workload.
