An M1 Mac mini’s electricity cost for a 24/7 YouTube stream depends on the power draw of the whole setup while it is actually streaming and on the rate on your electricity bill. Apple’s published idle and CPU-maximum figures give useful reference points, but neither is a measurement of your encoder workload.
For a fair comparison with a VPS, include the home setup’s measured wall draw and electricity rate, then include both compute and outbound transfer in the VPS estimate. There is no universal cheaper option: the result changes with the workload, bitrate, local tariff, VPS terms and equipment you already own.
Why there is no universal cost winner
A home Mac and a virtual private server (VPS) are billed in different ways. With the Mac, the recurring cost you can estimate directly is electricity; you may also have an internet plan, equipment and replacement costs. With a VPS, the bill may include a compute plan and separate charges or limits for outbound data. A headline compute price is not the full streaming cost if the plan restricts transfer or charges for it.
There is also a difference between marginal cost and total cost. If you already own the Mac and it would otherwise be switched off, the electricity used during the stream is a new expense, while the purchase price is sunk. If you are buying a machine specifically for a channel, the purchase cost and likely service life belong in your decision too. The same distinction applies to a VPS: compare the service bill you would actually pay, not a hypothetical rate that excludes required capacity or transfer.
The channel’s workload matters. A static devotional image with audio, a lofi loop, a local news playlist and a scene with motion or overlays may ask different things of an encoder. Whether the Mac is merely passing through already-compressed video, encoding a live output, or also recording locally changes what it is doing. A low idle reading cannot stand in for all those cases.
The comparison also needs the same delivery target. If one estimate is for a modest bitrate and another assumes a higher one, the VPS transfer and home network requirements are not equivalent. Compare the same stream duration and output bitrate first; then separately note costs that differ, such as recording or network equipment. For more on choosing between a local setup and hosted approaches, see this guide to cloud alternatives for always-on YouTube channels.
Measure the desktop during the actual workload
The most useful number for your electricity calculation is the average power measured at the wall while the complete setup is doing its normal job. Use a plug-in electricity meter rated for your mains supply and the connected load. Connect the Mac and the equipment you want included, start the actual encoder and stream, and allow the setup to settle before recording the reading. A brief glance at a momentary watt display may miss changes in encoding activity or connected devices.
Decide first what “whole setup” means. A Mac-only measurement excludes a display left on, powered speakers, an external drive, a capture device, a USB hub and network equipment. If your router would be on regardless of the channel, you may reasonably leave it out of the incremental cost; if you are comparing the complete systems, count it consistently. Write down what the meter includes so that a later comparison does not mix a Mac-only figure with a full-room figure.
Measure under the conditions you plan to maintain: your normal playlist, output settings, overlays, audio path, recording choice and display state. If the workload changes during the day, take readings across representative periods rather than assuming one instant is typical. For example, a channel might show a nearly static image overnight and play a more complex sequence at other times. Use a time-weighted average if you can establish how long each state lasts.
Keep the stream itself in view during the test. YouTube’s encoder setup guidance describes entering the server URL and stream key in encoder software. A local meter tells you electrical draw, not whether the upload is stable or the broadcast is reaching YouTube. Check the live output and the encoder’s status while measuring, and keep the channel’s intended bitrate and resolution consistent with the planned run.
A useful companion is a simple log: date, meter reading, included devices, stream settings, whether local recording was on, and the electricity rate you intend to use. That makes the result reproducible if you later change a scene or add a display. It also prevents you from treating a reading from a different setup as if it were your own.
Use idle power only as a baseline
Apple’s power-consumption table gives 6.8 W idle and 39 W CPU maximum for a tested M1 Mac mini configuration with 16 GB of unified memory and a 2 TB SSD. These published figures are reference points, not a direct test of a 24/7 broadcast, and a different configuration or attached equipment can alter your result. Apple separately lists 150 W maximum continuous power for the M1 Mac mini; that is a product rating, not a typical streaming draw. The Apple power-consumption information and M1 Mac mini technical specifications provide the underlying context.
At 6.8 W, 8,760 hours in a 365-day year works out to about 59.6 kWh. At 39 W, the same period works out to about 341.6 kWh. These are calculations from Apple’s reference values, not a promise that your setup will fall in that range. They help show the scale of the question and why it is worth measuring rather than assuming the Mac’s idle figure applies throughout an active stream.
Idle power is only the baseline because the computer is no longer idle once it is running an encoder, processing media and sending a continuous output. Conversely, the 39 W CPU maximum for Apple’s tested configuration is not necessarily what your channel will use: it refers to a published CPU test condition, not a defined YouTube stream. Treat both as bookends for context, then substitute a measured average where possible.
The distinction matters especially when the desktop does more than stream. Recording a local copy, rendering overlays, driving a monitor or running unrelated work can increase the whole-system reading. If you are also troubleshooting simultaneous recording and streaming, this article on dropped frames when OBS records and streams at once addresses the workload question from the reliability side. Its topic is not a power estimate, so still use your meter for cost.
Calculate home electricity cost
The arithmetic is straightforward once you have an average wall reading and your billed rate. Multiply watts by operating hours, divide by 1,000 to convert watt-hours to kilowatt-hours, then multiply by the all-in price per kWh. For continuous operation over a 365-day year, the hours are 24 × 365, or 8,760.
Annual kWh = average watts × 8,760 ÷ 1,000.
Annual electricity cost = annual kWh × billed cost per kWh.
For illustration only, at an assumed $0.15 per kWh, Apple’s 6.8 W idle reference converts to about 59.6 kWh per year and approximately $8.94 per year, or $0.75 per month. The 39 W CPU-maximum reference converts to about 341.6 kWh and approximately $51.25 per year, or $4.27 per month. The assumed rate is not a tariff recommendation or a universal price; replace it with the rate on your own bill.
If your bill uses different rates by time of day, calculate energy in each period using the applicable rate, then add the results. A single average rate is a practical simplification only when it represents the hours the stream runs. Check whether taxes and supply charges are included in the per-unit figure you use; fixed charges that do not change when the Mac runs should not be attributed wholly to the stream.
For an actual meter showing energy over a representative period, use its kWh reading directly. Divide that energy by the measured hours to get an average if you want to extrapolate, or multiply the observed period’s kWh by the number of comparable periods in your operating schedule. If the stream changes substantially between periods, measure those periods separately and add them. Do not convert a brief peak watt reading into a full-year estimate.
Include VPS compute and outbound transfer
A VPS estimate needs two separate checks: whether the compute plan can run your chosen streaming workflow, and what it costs or permits to send the stream’s data out. Provider listings may bundle transfer, set a monthly allowance, charge for usage above an allowance, or distinguish transfer by location or plan. Those terms change and cannot be inferred from a compute headline. Read the provider’s own current plan and billing documentation before comparing it with a measured electricity bill.
Bitrate connects the VPS calculation to the home comparison. A stream sent at a higher bitrate carries more data over the same period. The exact billed quantity depends on the provider’s counting method and any protocol overhead or additional outputs, so use its stated terms and calculator, if offered. If you send primary and backup streams, or run additional outputs, account for them rather than treating one channel’s bitrate as the entire transfer bill.
A plain way to compare is to make a small worksheet. Record the Mac’s whole-setup average watts, planned operating hours and local unit rate. For the VPS, record the relevant compute charge, included outbound allowance, expected outbound usage at the matching bitrate and any overage or required add-on. Keep billing periods aligned: a monthly VPS plan should be compared with a corresponding month of home electricity, not with a one-off day of testing.
There is no cloud price calculation here because no current, like-for-like VPS plan and transfer terms have been established for this article. That omission is preferable to presenting a compute-only price as a complete answer. A VPS may suit you if the monthly service terms are clear and you do not want to keep a desktop and home connection involved; a Mac may suit you if you already own it, can measure modest workload draw, and value local control. Neither observation decides the bill for your case.
If your main objective is to avoid leaving a computer at home running the broadcast, a managed workflow can remove that particular task: StreamNeo lets you upload a file, provide your YouTube stream key and have the stream continue without your computer switched on. That addresses the computer-at-home burden, not every comparison variable; you still need to check your file, channel readiness and the operating arrangement that fits your needs.
Compare the same bitrate and operating period
An apples-to-apples comparison starts with an identical output: same channel, resolution, bitrate, stream hours and whether the source is a loop or a more demanding programme. Then distinguish energy use from transfer. The Mac consumes electricity while encoding and operating the connected gear; a VPS sends outbound data under its provider’s transfer rules. Neither figure alone says whether the connection or service is reliable enough for your channel.
| Item | M1 Mac mini at home | VPS | What to make comparable |
|---|---|---|---|
| Compute or processing | Measure the Mac and included equipment during the stream | Check that the chosen plan can run the actual workflow | Same encoder task and output settings |
| Energy or transfer | Apply your billed electricity rate to measured kWh | Check included outbound data, usage counting and overage terms | Same bitrate and broadcast duration |
| Other recurring inputs | Consider home internet and any always-on peripherals you include | Consider required storage, transfer additions or supporting services | Count only what the setup needs, and label exclusions |
| Practical dependency | Home power, computer and internet connection | Provider availability, plan limits and account configuration | Compare continuity requirements separately from price |
YouTube’s streaming tips recommend upload bandwidth headroom above the total bitrate. The research guidance gives a 20% headroom recommendation, but your own connection still needs testing under real conditions. An Ethernet socket on the Mac does not establish your internet service’s upload speed or reliability. Budgeting electricity or VPS transfer cannot fix a weak upstream connection.
Also decide whether the stream needs to be archived. YouTube says streams under 12 hours are automatically archived, so do not assume an uninterrupted 24-hour run will be retained as one complete video. If keeping the entire programme matters, plan separate recordings or another archive approach and include any resulting storage or recording workload consistently in both scenarios.
First-time live streaming can take up to 24 hours to become enabled, and YouTube’s get-started guidance says a channel needs verification and no live-streaming restrictions in the preceding 90 days. Requirements can change, so check the current YouTube eligibility guidance before scheduling a launch. These are readiness checks, not costs, but a comparison that assumes a broadcast can start immediately may not fit your timeline.
Check what each estimate includes
A reliable estimate is explicit about boundaries. For the Mac, say whether the figure covers only the mini or the meter reading for the complete setup. Include a display only if it will stay on; include a drive, speakers or network gear only if they are part of the chosen comparison. Where the router would be on anyway, its whole power draw may overstate the added cost of the stream. You can show both an incremental estimate and a whole-setup estimate if that distinction helps.
Equipment purchase and replacement are separate from electricity. A Mac you already own has a different decision from one you would purchase for a channel, just as a spare monitor is not a new expense if it would remain powered regardless. If you are planning a new setup, list purchase costs separately rather than silently adding them to one side while leaving them off the other. Do not treat an electricity estimate as the complete cost of ownership.
For the VPS, include the compute plan actually required, its region or configuration if that affects terms, outbound transfer included, the expected transfer volume and any fee for usage beyond the allowance. Note whether storage, backup, support, or another service is necessary for your chosen workflow. If a provider’s site lists prices or limits, attribute and date them when you write them down; terms can change. This article does not state a vendor price because a relevant current plan has not been established.
Reliability has practical costs that are hard to capture in one number. A home desktop depends on power, internet and the machine staying available; a VPS shifts the dependence to the provider and your configuration. You may need a backup connection or a restart plan in either case. The guide to keeping a 24/7 stream live after Windows restarts is Windows-specific, but it illustrates why recovery planning belongs beside a simple monthly bill comparison.
Before you choose, write down the estimate’s period, included equipment, measured or assumed wattage, electricity tariff, stream bitrate, transfer allowance and excluded items. Mark assumptions plainly. If one number is measured and another comes from a plan page, say so; do not give them a false appearance of equal precision. The best estimate is the one whose inputs you can check and revise when the channel changes.
Before committing, compare the operating options on the pricing page. When the file and channel are ready, start free — 24-hour trial, no card.
FAQ
How much electricity does an M1 Mac mini use running all day?
Apple publishes 6.8 W idle and 39 W CPU maximum for a tested M1 Mac mini configuration, which calculate to about 59.6–341.6 kWh across 8,760 hours. Neither number directly measures your streaming setup; use a plug-in meter during the real workload and count connected equipment deliberately.
What does it cost to run the Mac mini 24/7?
Multiply the measured average watts by your operating hours, divide by 1,000, then multiply by your billed price per kWh. The $0.15/kWh example in this article is illustrative only; your bill, time-of-use periods and whole-setup draw determine your own cost.
Is a VPS cheaper than a Mac mini for a continuous stream?
There is no universal winner from the information available here. Compare measured home electricity and equipment with the VPS compute plan plus its outbound transfer terms at the same bitrate and operating period; a compute-only price is incomplete.
Will YouTube archive a continuous 24-hour stream?
YouTube says streams under 12 hours are automatically archived, so do not assume one uninterrupted 24-hour broadcast will be saved as one complete video. If retention matters, plan separate recordings or another archiving approach and check current YouTube guidance.
