A dedicated PC’s budget has two parts: the one-off cost of the computer and display, and the recurring cost of running them. For electricity, use the average power drawn at the wall during representative playback, multiply by the hours you expect to run, and apply your local price per kilowatt-hour.
A PC can play YouTube continuously for long periods, but it is not a guarantee of unattended all-month playback. YouTube documents a “Continue watching?” prompt on the web after 60 minutes of uninterrupted viewing with Autoplay enabled, so budget for the attention that may be needed as well as the hardware and power.
Separate the purchase from the monthly bill
Start by putting every cost into one of two columns: one-off setup costs and recurring costs. The PC and display belong in the first column unless you are financing or renting them. Electricity belongs in the second. Internet and subscriptions belong there only when this setup adds a charge or you choose an optional paid feature.
This separation prevents a common budgeting mistake: treating the purchase price as the whole cost, or treating every possible service charge as inevitable. If you already own a suitable monitor and have an internet plan with enough capacity, neither is a new purchase for this project. If the computer needs replacing, or the setup requires a new plan, those are real additional lines.
Write down the intended use before comparing equipment: which video or playlist will play, the resolution you need, whether the display must stay on, and whether someone can respond if playback pauses. A devotional channel showing a static image with audio may have different display needs from a local news loop whose text must remain visible. Neither example implies a particular power draw; that depends on the actual equipment and settings.
The purchase budget is easiest to compare when it is not mixed with operating cost. Keep any accessories you genuinely need—such as a keyboard for setup or a surge protector—visible as separate one-off lines rather than assuming they come with the PC. Do not add speculative upgrades before you know that the intended playback fails without them.
Budget for the PC and display
For the upfront line, price a desktop PC that can play your intended YouTube content in a current browser, plus a display only if you need one. YouTube recommends a current browser and operating system for computer viewing; it does not establish that one named PC model is suitable for every possible video or unattended workload. Choose for the task you intend to run, not an imagined requirement for maximum performance.
A practical comparison can record the same information for each candidate: purchase price, whether a display is included, the resolution it can play in your browser, and its measured wall draw under representative playback. If you cannot test a candidate before buying, mark power use as unknown. Do not infer its continuous cost from the power supply’s maximum rating: that rating is not the same as the power the whole setup draws while playing a video.
A monitor may be an existing asset, a new purchase, or unnecessary if you can operate the PC headlessly after setup. Include its cost only if you need to buy one. For electricity, however, include its draw if it will remain switched on; a PC-only measurement cannot account for a continuously running display.
You can read about how to prepare content and playback choices in this guide to building a 4K YouTube Live playlist that repeats in order. A playlist design does not remove the need to consider what the player does when a video ends, or how YouTube’s own playback prompts behave. If your priority is a practical trial before making the channel public, the YouTube lofi stream test checklist is a useful companion.
For a PC that is already on hand, its purchase cost is sunk for this decision, but its electricity is not. You can still compare its measured draw with the cost of replacing it or using a different approach. That comparison should use actual candidate prices and measurements, not a blanket claim that newer or smaller machines always cost less to run.
Estimate monthly electricity from wall power
Use this calculation for the computer, then repeat it for a display or other equipment that will also remain on:
Monthly energy (kWh) = average wall draw (watts) ÷ 1,000 × hours per month.
Monthly electricity cost = monthly energy (kWh) × your electricity price per kWh.
For a 30-day month running continuously, the time input is 720 hours. That is an arithmetic assumption, not a prediction that the computer will in fact play without interruption. If you will switch equipment off for part of the day, replace 720 with the hours you actually expect it to be powered on.
Measure the complete setup at the wall while it is playing the intended content and resolution. Use a representative period rather than a moment during boot or an unusually demanding task. If you have separate readings for PC and display, calculate each and add their kWh. If you only have a PC reading, say so in your budget and do not present it as the combined total.
The following examples use assumed average draws, not test results for a particular computer. They apply the 2025 U.S. residential annual average of 17.30 cents per kWh reported by the U.S. Energy Information Administration (EIA). The figures exclude a display, taxes or fixed bill charges, internet, purchase cost, replacement parts and subscriptions.
| Assumed average wall draw | Energy over 30 days at 24 hours/day | Cost at 17.30¢/kWh |
|---|---|---|
| 50 W | 36 kWh | $6.23 |
| 100 W | 72 kWh | $12.46 |
| 200 W | 144 kWh | $24.91 |
These are illustrations of the formula, not promises about what your machine will consume. A display left on adds its own energy; a different measured draw or local tariff changes the estimate. The EIA reports that the 2025 average retail price for all utility customer types ranged from 8.20 cents per kWh in North Dakota to 35.72 cents in Hawaii. That state comparison is not a household-specific rate. Use the price on your bill or applicable tariff for a useful estimate. See the EIA’s explanation of electricity prices and factors affecting them and its electricity price tables for the published data.
If your bill has a time-of-use tariff, use the applicable rate for the hours you expect to run the equipment rather than assuming one flat rate. Likewise, fixed bill charges that would be present with or without the PC do not necessarily represent the incremental cost of this setup. The estimate here is for energy use; your bill may contain other items.
A simple plug-in power meter can help establish the wall draw, if one is available and suitable for the equipment. Do not confuse a single brief reading with a guaranteed monthly average. Playback settings, connected equipment and normal changes in activity can affect the reading. Record what was connected and what was playing so that your estimate can be repeated after you change the setup.
Decide whether internet or a subscription adds cost
Include internet in the recurring budget only if the dedicated PC requires a new plan, a paid upgrade, or causes you to cross a data cap that results in a charge. If it uses an existing connection with sufficient capacity and no extra fee, record that the existing plan is being used rather than assigning an invented monthly cost to the stream.
Resolution affects the connection you should plan for. YouTube’s published sustained-speed recommendations are 5 Mbps for 1080p and 20 Mbps for 4K UHD. These are YouTube recommendations, not a promise of uninterrupted playback, and your household may have other devices sharing the connection. Check the connection where the PC will sit and at the times it will be used. You can consult YouTube’s recommended internet speed information alongside your provider’s plan and any data-use terms.
Do not treat bandwidth and monthly data allowance as the same thing. A plan may have sufficient speed but a data cap, or no additional charge for this use. If your provider charges for excess use, check its current terms and whether the PC’s video playback changes your usage enough to matter. The answer depends on resolution, viewing hours, connection terms and other use; this article cannot infer a charge without those details.
A subscription is optional. You might decide to pay for YouTube Premium if you want ad-free playback, but do not add it automatically to the cost of a dedicated PC. YouTube says individual Premium, Premium Lite or Music Premium accounts can stream video or audio on one device at a time; household-plan terms differ. Check the current official terms for your region before relying on a plan for multiple devices. No regional price is assumed here.
Keep the subscription question separate from the playback-continuity question. A paid account is not a reason to assume a computer will advance unattended indefinitely. If ad-free viewing is important, confirm which account and plan fit your use, then price that line from the current YouTube page for your country.
Understand Autoplay’s limits for unattended viewing
Autoplay does not necessarily repeat the same video. YouTube Help says, “When Autoplay is on, another related video will be played automatically after a video ends.” If your aim is a fixed sequence, use a playlist or another intended playback arrangement, and check what happens at its end. Do not budget on the assumption that the same clip repeats forever simply because Autoplay is enabled.
There is a more direct limitation for unattended web playback: YouTube documents that a “Video paused. Continue watching?” prompt may appear after 60 minutes of uninterrupted viewing on the web when Autoplay is enabled. YouTube explains that the prompt is intended “to protect your watch history and help make sure you don't use internet data if you're not actually watching YouTube.” If nobody responds, the next video may not begin. A dedicated PC does not by itself remove that interruption.
That is why the title’s “all month” should be treated as a planning goal, not a guarantee. If a person can check the channel and respond to a prompt, include that attention in the operating plan. If nobody is available, do not assume a standard browser session will advance videos unattended for a whole month. YouTube’s Autoplay Help page and Continue watching? Help page describe the relevant behaviour; check them again before relying on a particular setup.
A browser and operating system that are kept current, with excess tabs closed, are sensible playback basics. YouTube’s troubleshooting guidance also suggests trying Chrome or another supported device if playback fails. These steps may help resolve ordinary issues, but they are not evidence that any particular PC has been tested for month-long reliability. For a more general look at operational risk, see how to test a 24/7 setup before committing.
There are two different types of interruption to plan for. One is expected behaviour such as the viewing prompt; another is a playback, browser, power or internet problem. A purchase budget should not hide the need for someone to notice and respond to either. If your actual goal is to keep a YouTube live broadcast running from a file while your own computer is switched off, StreamNeo removes the need to leave this dedicated PC playing the video locally; you still need to consider whether that approach fits your channel and check current YouTube requirements.
Build your own monthly budget
Make the calculation in a small worksheet and keep assumptions visible. A useful layout has one-time costs at the top and recurring lines below. Enter local currency and actual quoted prices rather than borrowing the illustrative U.S. electricity figures if you live elsewhere.
| Budget line | What to enter | When it belongs in the total |
|---|---|---|
| PC | Actual purchase price | If buying or replacing the computer for this setup |
| Display | Actual purchase price, if needed | If you do not already have a suitable display |
| Other setup items | Necessary accessories or cabling | Only if required and not already owned |
| PC electricity | Measured average wall watts, hours, local price | Every month the PC runs; calculate from the formula above |
| Display electricity | Display’s measured or separately estimated draw | If the display remains powered on |
| Internet change | Actual added plan or usage charge | Only if the setup creates an additional cost |
| Subscription | Current regional price for a plan you choose | Only if you want and use that subscription |
| Attention and maintenance | Who checks prompts, updates and recovery | A planning note, not an invented monetary fee |
For the electricity lines, preserve the inputs: average watts, monthly hours, and price per kWh. That lets you replace an estimate with a wall measurement later without rebuilding the whole budget. If you want a monthly equivalent for the upfront equipment, you can divide the purchase cost by the number of months you choose to use for planning, but label that as your own accounting choice rather than a monthly bill. It does not change when the retailer charges you.
Then make a second version for the actual operating schedule. If the PC runs only during staffed hours, calculate those hours rather than 720. If it runs all day but the monitor can be switched off after setup, remove the display’s operating energy only if that is how you will really use it. A budget is useful when the assumptions describe the real arrangement, not the least expensive hypothetical one.
You can compare a dedicated computer with other operating approaches by asking the same questions: what must be purchased, what is the measured energy use, what connection is needed, and who must intervene when playback stops? The guide to starting a 24/7 LoFi radio station on YouTube covers a broader channel setup; it does not replace the PC-specific arithmetic here. For channel operation choices, keep the budget tied to the actual content and whether a human can monitor it.

FAQ
How much electricity will a PC use in a month?
It depends on the average power drawn by the complete equipment you leave on. Multiply average wall watts by the hours used, divide by 1,000 to get kWh, then multiply by your local electricity price per kWh. For a 30-day month at continuous operation, the hours assumption is 720; measure the display separately if it will also stay on.
Can YouTube Autoplay loop one video all month?
No such guarantee should be assumed. With Autoplay enabled, YouTube says another related video can play after a video ends, rather than promising the same video will repeat. On the web, a “Continue watching?” prompt may appear after 60 minutes of uninterrupted viewing, so an unattended session can stop advancing until someone responds.
Do I need to add internet and YouTube Premium to the budget?
Only add an internet cost if this setup requires a new plan or creates a charge under your existing plan, such as crossing a data cap. A YouTube subscription is optional, for example if you want ad-free viewing; check current regional terms and prices before including it.
What connection speed should I plan for?
YouTube recommends sustained speeds of 5 Mbps for 1080p and 20 Mbps for 4K UHD. Those recommendations are not an uptime promise, and other devices may share the connection. Check your actual connection at the intended location and compare it with your provider’s plan.
