Calculate it with monthly kWh = average watts ÷ 1,000 × 24 × 30.4, then multiply the kWh by your price per kWh. The 30.4-day factor gives an approximate average month; use the actual number of days for a specific bill.
Estimate the monthly electricity cost
Use the PC’s average wall draw—not a component’s advertised power rating—and the marginal electricity rate that applies to you. The result estimates the energy charge for the equipment included in the measurement. It excludes fixed service charges, unusual tariff tiers, and other household loads.
- Convert watts to kilowatts: divide average watts by 1,000.
- Calculate monthly energy: multiply kilowatts by 24 hours and 30.4 days.
- Calculate cost: multiply monthly kWh by your electricity price per kWh.
For example, 100 W ÷ 1,000 × 24 × 30.4 = 72.96 kWh in an average month. At a rate of $0.20/kWh, that would cost $14.59 in energy charges. Replace the example rate with the applicable price on your bill.
Illustrative U.S. calculations
The U.S. Energy Information Administration reported a national residential average of 17.45 cents/kWh for January 2026 and a 2025 annual average of 17.30 cents/kWh in its March 2026 Electric Power Monthly table. These are dated national averages, not a substitute for your local tariff. At the January figure, the arithmetic examples are:

| Average wall draw | Energy in an average month | Cost at $0.1745/kWh |
|---|---|---|
| 50 W | 36.48 kWh | About $6.37 |
| 100 W | 72.96 kWh | About $12.73 |
| 200 W | 145.92 kWh | About $25.45 |
These are scenarios, not measurements or claims about what an old gaming PC typically draws. A 24/7 load operates for 720 hours in a 30-day month or 744 hours in a 31-day month; the formula uses 30.4 days as a monthly average. The EIA explains that watts measure power at a moment, while watt-hours measure energy over time; one kWh is one kilowatt used for one hour. See the EIA Electric Power Monthly for its electricity data.
Measure the PC’s real wall draw
A suitably rated plug-in electricity usage monitor or watt meter measures the complete load at the outlet. CPU or GPU telemetry alone does not include the rest of the system or account for power-supply losses, so it is not a direct substitute.

- Connect the equipment that will remain powered to a suitably rated plug-in energy monitor. Follow the monitor’s rating and instructions.
- Include only equipment that will actually stay on. If the monitor or display will be off during streaming, leave it out; measure or account separately for a display, capture device, or other equipment that remains powered.
- Run the PC in representative streaming conditions. An idle reading or maximum component rating may not reflect the stream workload.
- If the workload varies, record energy used over a representative period and divide by elapsed hours. Convert the resulting average watts with average watts = kWh × 1,000 ÷ hours.
- Multiply the monthly kWh by your applicable marginal rate. If your plan uses time-of-use prices or tiers, account for the rates that apply during the measured period.
No particular energy-monitor model is specified here. Use the measured result for the equipment and workload you intend to run.
What YouTube’s stream settings tell you—and what they do not
YouTube describes an encoder as software or hardware that converts video to a digital format for streaming. Its guidance covers RTMP/RTMPS and H.264, H.265/HEVC, and AV1 options; recommended bitrate varies with resolution, frame rate, and codec. For example, YouTube’s table recommends 5–14 Mbps for 1080p at 30 fps using H.264. That recommendation helps configure a stream, but it does not establish the power draw of a particular PC.

Test using representative audio and motion, then check YouTube’s stream health. YouTube says streams under 12 hours are automatically archived; that is an archival rule, not a guarantee that an old computer can encode continuously or that a stream will stay connected. Consult YouTube’s live encoder settings guidance for its current recommendations. Older hardware’s encoding capability and around-the-clock reliability depend on the specific machine and configuration.
Compare the PC with a cloud alternative
If the goal is to keep uploaded videos playing as a YouTube live stream, compare the PC’s measured cost with a cloud service using the same stream workload, electricity price, encoding quality and reliability needs. StreamNeo is first to consider as a hosted option: it loops uploaded videos from the cloud, so the home computer can be off, with any uploaded quality up to 4K 60fps at one flat price per slot and a free first day.

Or let it run in the cloud
With StreamNeo, upload a recording or build a playlist, add your YouTube stream key once, and go live. It plays uploaded videos to YouTube; it does not stream from a camera. Nothing has to stay powered on at home. Every slot supports the uploaded quality up to 4K 60fps at one flat price, and StreamNeo automatically recovers if YouTube drops the stream. The first day is free with no card. Monthly pricing is $9.99 per month.
Compare that price with the PC’s measured electricity cost, while also weighing equipment wear, encoding capability and the value of automatic recovery. Start a StreamNeo free day.

Limits of a commonly cited gaming-PC figure
A surfaced Lawrence Berkeley National Laboratory study result reports 1,394 kWh/year for an average gaming computer plus display under a profile based on 4.4 hours of gaming per day. The year was not established in the surfaced result. That modeled gaming-use figure includes a display and is not a 24/7 server test, so it should not be used as the expected consumption or cost of your setup. A wall measurement under your own workload is more relevant.
