How Much Does It Cost to Leave a Gaming PC On for a YouTube Loop?

Estimate your YouTube loop’s electricity cost with a wall-side power measurement, your actual runtime, and your local price per kWh.

There is no reliable one-size-fits-all price: the cost depends on your PC’s average power draw at the wall, how many hours it runs, and your electricity rate. Calculate it as (watts ÷ 1,000) × hours × price per kWh. Measure the setup rather than treating a gaming PC’s power-supply rating as its actual consumption.

Calculate the cost from your actual power draw

Watts measure power at a moment in time; kilowatt-hours (kWh) measure energy accumulated over time. Convert the measured watts to kilowatts, multiply by runtime, then multiply by your electricity price per kWh.

Period Calculation for continuous operation
One day (average watts ÷ 1,000) × 24 × your rate per kWh
Average month (average watts ÷ 1,000) × 730 × your rate per kWh; for a specific bill, use 24 × the actual days in that billing month
One 365-day year (average watts ÷ 1,000) × 8,760 × your rate per kWh

For overnight-only use, substitute the actual hours per night and number of nights. Do not use the 24/7 annual hours unless the system really runs continuously.

Measure the whole setup you want to cost

A plug-in electricity usage monitor can measure power at the wall. The average reading during the activity you care about is the useful input—not the maximum wattage printed on the power supply, nor a GPU-only reading if you want the entire computer’s consumption. A PC-only measurement excludes a separately powered monitor and other peripherals; measure or add those devices if you want the channel setup total. A practical cost guide likewise recommends wall-side measurement and distinguishes the complete setup from GPU-only consumption: iTechGuides’ gaming PC electricity-cost guide.

Measure under the relevant conditions: playing the loop, encoding or streaming if those are part of your method, and idle or sleep if the PC spends time in those states. Gaming, video playback, encoding, and idle operation need not draw the same power. No cited measurement establishes one universal wattage for a gaming PC continuously playing a YouTube loop.

Worked examples using a U.S. electricity benchmark

The U.S. Energy Information Administration reports a 2025 average residential electricity price of 17.30¢ per kWh; the figure is preliminary 2025 data published in 2026, not a rate for every household. EIA notes that “Electricity prices vary by locality based on the availability of power plants and fuels, local fuel costs, and pricing regulations.” Use your own bill’s applicable rate for a personal estimate. The EIA’s reported 2025 range of 8.20¢ per kWh in North Dakota to 35.72¢ in Hawaii covers customer types generally, not residential customers alone. See the EIA electricity data browser and its explanation of electricity prices.

Illustrative average draw Energy at 24/7 for a 365-day year Annual cost at 17.30¢/kWh
20 W 175.2 kWh About $30.25
40 W 350.4 kWh About $60.62
80 W 700.8 kWh About $121.24
100 W 876 kWh About $151.55

These are arithmetic examples, not measured or typical draws for a gaming PC running YouTube. The 20 W, 40 W, and 80 W figures are scenarios; the estimates use 8,760 hours and the stated EIA rate. Small differences from other published examples can result from rounding or annualization conventions. For a rough shortcut at this benchmark, each continuously drawn watt costs about $1.52 per year.

Why a published gaming-PC average may not fit

A 2019 Lawrence Berkeley National Laboratory modeled profile for an average gaming computer plus display estimated 1,394 kWh per year, based on 4.4 hours a day in gaming mode. It is dated modeled usage, includes a display, and does not represent one person’s equipment or a computer running a YouTube loop 24/7. It is context, not a substitute for measurement. The report is available from Lawrence Berkeley National Laboratory.

Reduce the cost estimate’s uncertainty

  • Measure average wall draw during the actual loop workload, rather than assuming a wattage from the PC’s gaming specifications.
  • Record the runtime you intend to use: overnight hours, daily hours, or a full 24-hour schedule.
  • Use the electricity rate that applies to your home and billing period; a national average is only a comparison point.
  • Decide whether the estimate includes just the PC or also a monitor and other separately powered equipment.
  • For a bill-period estimate, use the number of days in that billing period rather than assuming every month has 30 days.

Keep a YouTube loop running without leaving a PC on

For a do-it-yourself setup, keep the PC and any required streaming software running, with a stable internet connection and power settings that do not put the computer to sleep. Measure the full arrangement at the wall and apply the formula above; include any monitor or other equipment you leave powered. The electricity estimate will reflect the measured draw and your local rate, while the computer still needs to remain available for the stream.

Or let it run in the cloud

StreamNeo keeps an uploaded-video YouTube channel live from the cloud: upload a recording or build a playlist, add your YouTube stream key, and go live. Your home computer and connection do not have to stay on. It streams the uploaded video as made, up to 4K 60fps, at one price per slot regardless of quality, and can automatically recover if YouTube drops the stream. The first day is free with no card. Monthly pricing is $9.99 per month. Start the free day with StreamNeo.
