A NUC-style mini PC’s monthly electricity cost depends on its average wall draw, how many hours it stays powered, and your electricity price. Multiply average watts by powered hours per day and days, divide by 1,000, then multiply by your price per kWh: at the U.S. 2025 residential average of 17.30¢/kWh, a hypothetical 10 W running continuously for 30 days costs about $1.24; 20 W costs about $2.49.
Those are arithmetic examples, not measurements of a NUC or observed YouTube-streaming costs. No representative NUC wall-power result for a creator’s live-streaming workflow is established here, so measure your own configured computer during a typical session and use your local rate for a useful personal estimate.
Why there is no single monthly cost
The phrase “a NUC-style mini PC” describes a compact computer, not one fixed electrical load. Model, configuration, operating mode and workload can all affect how much power the computer draws. A stream that plays a pre-rendered file may put different demands on the system from a scene with live graphics, audio processing or other applications running. Even the same computer can have different average draw at different times.
The cost also depends on the boundary you want to count. A meter placed between the wall and the mini PC measures the computer and its power adapter together. It does not include a display, router, audio equipment or other devices plugged into separate outlets. If you leave a monitor on beside the PC, its use is a separate addition unless your measurement includes it.
Finally, electricity prices differ by location, tariff and household. A U.S. national average can make an example easy to check, but it is not a price to use automatically in India or anywhere else. Your bill’s applicable per-unit rate is a better input; if your bill has different time bands or charges, decide which part of the bill is relevant to the extra electricity use and make that assumption explicit.
This is a question about the electricity used by the streaming computer, not the cost of internet service, YouTube, the original video production or a computer purchase. Keeping those categories separate makes it easier to compare a local PC setup with a different way of keeping a channel live.
Measure average wall draw
For a personal estimate, measure the computer at the wall while it is doing the work you intend to run. A plug-in power meter can report watts or energy use, depending on the model. Follow the meter’s instructions, connect the mini PC through it, and let the session reflect your real stream: the same video or scene, encoding choices, software, peripherals and background tasks you expect to use overnight.
A single glance at the meter is not necessarily representative. The computer may briefly draw more while starting software, loading media or handling a task, and less during quiet periods. If the meter can track energy over a representative period, use its record and divide energy by the elapsed hours to find an average power draw. Otherwise, take readings across different parts of a normal session and treat the resulting estimate as approximate. Do not present a short observation as a universal result for a model.
Keep a note of what is connected and included. If the mini PC alone is measured, call it the PC-only estimate. If you measure a power strip carrying the PC and other gear, say which devices were connected. Include a display only if you deliberately include it in the measurement or measure it separately and add its consumption. This boundary matters when you compare alternatives: compare like with like.
The relevant number is average wall watts, not the maximum rating printed on a power adapter. That rating describes the adapter’s capacity, not what the computer continuously consumes. Likewise, a processor’s thermal design power is not a reading of the whole computer’s wall use during your stream.
You can also test the system in the state that matters. For a channel intended to run all day, measure while it is streaming and powered as it would be overnight, not while the PC is idle on the desktop. A separate idle measurement may help explain the difference, but it cannot stand in for the workload figure.
If the computer is also used for browsing or editing during some hours, decide whether to include those hours. For a channel cost estimate, use a representative streaming session and count the hours it is powered for that purpose. If the PC remains on for additional time, include that too when calculating the whole electricity use attributable to leaving it on.
Calculate monthly kWh
Once you have average watts and powered time, first calculate the energy used in kilowatt-hours (kWh):
Monthly kWh = average watts × powered hours per day × days ÷ 1,000.
Watts are divided by 1,000 because one kilowatt is 1,000 watts. The calculation assumes the measured average holds for the powered hours you enter. If the computer is powered continuously, use 24 hours per day. If it runs only during a scheduled window, use those hours instead.
For a month with a different number of days, enter the actual number you want to estimate. A 30-day month is convenient for comparisons, but it is an assumption rather than a special property of the formula. For a longer planning period, use the total powered hours in that period rather than forcing the calculation into a 30-day month.
Here is the reusable version, with electricity price applied in the next step:
Monthly cost = average watts × powered hours per day × days ÷ 1,000 × electricity price per kWh.
Use the same period for both time inputs: hours per day multiplied by days gives total powered hours. If your PC averages 10 W for 12 hours a day over 30 days, for example, the first calculation is 10 × 12 × 30 ÷ 1,000, or 3.6 kWh. That is a formula illustration only; it does not assert that a particular mini PC will average 10 W while streaming.
A simple spreadsheet can make the estimate reusable. Put average watts, powered hours per day, days and price per kWh in separate cells, then apply the formula. Keep units visible in the column labels. That makes it less likely that you will enter a monthly kWh figure where the formula expects a price per kWh, or confuse watts with kilowatt-hours.
Apply your electricity rate
Multiply the calculated kWh by the electricity price per kWh. If the bill quotes cents, convert cents to dollars before multiplying, or keep the calculation in cents and divide by 100 at the end. For instance, 17.30¢ is $0.173 per kWh.
Use the rate that best represents the extra electricity consumed. Household bills can contain charges beyond the energy rate, and tariffs may vary. If you are unsure which figure on a bill to use, check the tariff or ask the electricity supplier how the marginal energy charge is shown. The purpose is to estimate electricity attributable to the PC, not to imply that every fixed bill charge changes when the PC is switched on.
At the stated U.S. benchmark, a convenient shortcut for a continuously powered PC is about 12.4¢ per average watt per 30-day month. Multiply measured average watts by roughly 12.4 cents. The shortcut follows from 24 hours per day, 30 days and 17.30¢/kWh. It is only for that rate and period; for a local price or a shorter daily schedule, use the full formula.
The U.S. Energy Information Administration reports a 2025 annual average residential price of 17.30¢/kWh, using Electric Power Monthly Table 5.3 and February 2026 preliminary data. You can check the EIA Table 5.3 data and its explanation of electricity prices. This national benchmark is for a transparent example; it is not a substitute for your own rate, and it does not apply to every reader.
Two illustrative wattage examples
The following calculations show how to use the formula. They do not report tested NUC draw, typical mini PC draw, or the result of a YouTube-streaming measurement. Each assumes the stated average watts persist for all 24 hours of a 30-day period and uses the U.S. 2025 residential average price of 17.30¢/kWh.
| Assumed average wall draw | Powered time | Monthly energy | Cost at 17.30¢/kWh |
|---|---|---|---|
| 10 W | 24 hours/day for 30 days | 7.2 kWh | about $1.24 |
| 20 W | 24 hours/day for 30 days | 14.4 kWh | about $2.49 |
For 10 W, the energy calculation is 10 × 24 × 30 ÷ 1,000 = 7.2 kWh. Multiplying by $0.173 per kWh gives $1.2456, which rounds to about $1.24 using the underlying calculation. For 20 W, the same steps give 14.4 kWh and $2.4912, or about $2.49. The examples are deliberately conditional: if your measured average is different, substitute it rather than treating either wattage as a recommendation or expectation.
The price difference scales with both draw and time. At a fixed electricity rate, doubling average watts doubles the calculated energy and cost. At a fixed wattage, running for half as many hours also halves the calculated energy and cost. A different local rate changes the money result without changing the kWh result.
For a personal estimate, make a second pass with your own inputs. If your PC averages 16 W at the wall during your representative stream, stays powered 20 hours per day, and your rate is 10¢/kWh, the formula uses those exact inputs: 16 × 20 × 30 ÷ 1,000 = 9.6 kWh; 9.6 × $0.10 = $0.96. This is another hypothetical arithmetic example, not a claim about a measured computer or an electricity price that applies to your home.
Account for powered hours and other equipment
“Streaming around the clock” does not necessarily mean every part of the setup is powered for the same hours. A PC might be scheduled off for maintenance, while a router stays on; a display may be switched off after setup; a backup device may only run occasionally. Calculate each device separately if you want a whole-setup estimate, then add the costs for the same time period.
For example, measure the PC on its own, record its daily powered hours, and calculate its kWh. Then measure a display separately if you want to include it. Do not add the display’s rated wattage to the PC’s measured average and call the result measured; either meter the combined arrangement or calculate the devices separately with clearly stated assumptions.
Power settings can affect use, but settings are model-dependent. Intel says NUC BIOS power-management options vary by model and describes pre-configured Balanced, Low-Power and Max-Performance states. Its NUC power-management guidance is useful for understanding available settings, not for predicting a particular live stream’s wall draw. Check your own model documentation before changing settings, then measure again if the change matters to your estimate.
An ENERGY STAR record for Intel NUC12WSH lists a model TEC of 27.6 kWh, long idle at 2.6 W, short idle at 5.2 W, sleep at 2.6 W and off at 1.1 W. The ENERGY STAR product record gives those certification or state values for that model. They are not a measurement of live YouTube streaming, and the annual TEC should not be converted into a streaming-cost claim. Certification and idle specifications can describe defined conditions; your workload still needs its own wall measurement.
If your channel plays a prepared video file, the PC workload may be different from a setup that renders scenes or runs other applications. The stream’s resolution, encoding method, streaming software and background tasks can matter. Watching YouTube on a computer is another workload again, and a watching figure should not be carried over as a broadcast figure.
Long-running reliability is a separate question from electricity cost. A PC that sleeps or restarts may interrupt a stream, regardless of its energy estimate; the practical settings are covered in how to prevent a Windows PC from going to sleep during a 24/7 YouTube live stream. If the aim is to keep a file-based channel live without leaving your own computer switched on, StreamNeo removes that specific burden by turning an uploaded video into a YouTube live stream that continues from the cloud; it does not change how you calculate a local PC’s electricity use.
Other setup details affect what you measure more than the formula. For a Windows-based loop, the guide to streaming from a laptop on BSNL broadband helps frame the computer and connection as separate parts of the setup. If your programme alternates promotional videos, fixing black gaps between store promo videos in an OBS YouTube live loop addresses playback continuity rather than power draw. Keep those operational questions distinct from the measured wattage and the bill rate.
Use the EIA benchmark carefully
A national average is useful because it makes the arithmetic reproducible. It is not a quote for your household. The EIA’s 2025 annual residential average is 17.30¢/kWh; the agency also reports a 2025 state range of 8.20¢ to 35.72¢/kWh in average retail prices across customer types. That state range includes all customer types, so it should not be labelled a residential-only range.
For a personal calculation, use your bill or tariff information rather than selecting a state figure or importing the U.S. average. If you live in India or another country, use the applicable local rate and currency. Where a bill uses slabs or time-of-use prices, a single rate may be only an approximation; note the assumption, or calculate separately for the periods when the PC is powered.
The benchmark also says nothing about how many watts your particular PC will draw. The rate sets the price of each kWh; measurement and powered hours determine how many kWh you buy. Keeping those inputs separate prevents a low national average from being mistaken for a low-power test, or a certification figure from being mistaken for a live-stream result.
A sound comparison between two setups therefore needs the same workload, the same measurement boundary, the hours powered in a month and the same local marginal rate. If one result includes the monitor and another does not, they are not directly comparable. If one is an idle reading and the other is measured during streaming, they answer different questions.
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
Is 10 W a typical NUC streaming draw?
No representative NUC wall draw for a YouTube creator’s live-streaming workflow is established by the sources used here. The 10 W figure is an input to an arithmetic example, not a measured or typical result. Measure your configured PC during a representative session.
Can I use the ENERGY STAR idle number to estimate a live stream?
Not as though it were a streaming measurement. The ENERGY STAR record lists defined model and idle-state values, while live streaming can involve different software and activity. Use the record for its stated conditions and measure the workload you want to price.
Does the U.S. 2025 rate apply to my electricity bill?
It is a benchmark for the examples, not a rate for every reader. Use the applicable per-kWh price from your own bill or tariff, in your local currency. If your price changes by time or usage band, a single rate may only be an approximation.
What should I include in a whole-setup estimate?
Decide whether you want the mini PC alone or the PC and peripherals together. Measure devices separately or meter the combined setup, and include the powered hours for each. Add their calculated costs only when the period and rate assumptions match.
