Measure the actual setup at the wall, convert its average watts to kilowatt-hours (kWh), then use the tariff that applies to your household. As an arithmetic example—not a typical-PC estimate—a steady 100 W draw for 30 days uses 72 kWh.
How to estimate the electricity use
For a steady average draw, use:
Energy (kWh) = average watts × hours used ÷ 1,000.
For 24/7 use over 30 days, that simplifies to average watts × 0.72. For example, 100 W × 24 hours × 30 days ÷ 1,000 = 72 kWh. This is a transparent calculation, not a claim that a typical Windows PC playing YouTube draws 100 W. For a period other than 30 days, use the actual number of hours.
Measure the whole setup at the wall
A plug-in electricity usage monitor can measure the average draw of the equipment connected through it. Reproduce the setup you intend to run: the Windows PC, browser or app, YouTube playback settings, and any display or network equipment you want included. Measure over a representative period rather than relying on a momentary reading.

- Include a monitor if it will remain on. A PC-only reading will not account for its power use.
- Include other devices, such as networking equipment, only if they are plugged through the meter; otherwise they are outside the measured total.
- Do not use the power supply’s rated maximum as the computer’s continuous consumption. It is not a measurement of average wall draw.
The result applies to the hardware, settings, and measurement period tested. Playback resolution and whether video continues overnight define the workload, but the available evidence does not establish a fixed wattage change for those choices.
Why published wattage figures are only context
A historical OECD/International Energy Agency table in Gadgets and Gigawatts: Policies for Energy Efficient Electronics (2009, figure 123) estimated 65 W for a desktop PC plus 32 W for a monitor in “Idle” mode, and 85 W for the PC plus 35 W for the monitor in “Active” mode. These dated estimates are neither measurements of YouTube playback nor predictions for a particular modern Windows PC. They do, however, illustrate why a display can matter when estimating the whole setup.

- Various Monitoring Parameters: The power meter plug can monitor the power (W), energy (kWh), volts, amps, hertz, power factor, cost, minimum and maximum power (W), cumulative days and time of your appliances. By switching 7 display modes, you can easily know the various parameters while the appliance is working. The home energy monitor can also calculate and display how much power your appliance uses and how much electricity bill it cost in cumulative time
- Upgraded LCD Display: With large screen size 2.36 inch x 1.85 inch, clearer monitor backlit, our electrical usage monitor can display the data clearer and more visible no matter day or night. 180°full wide viewing angles is great for reading and recording the data in any angles. No need to stand on the front of the display and bend over to read the numbers
- Adjustable Backlight Time: Our upgraded watt meter has 5 options of backlight time. The default backlight time duration is 10 minutes(bL-0). If you want to change the backlight time, you can press and hold "UP" and "DOWN" button at the same time to enter backlight time setting, then press "UP" and "DOWN" to select the backlight time (bL-0 =10 minutes, bL-1=1 hour, bL-2=4 hours, bL-3=8 hours, bL-4=always on), finally press the "COST" to save the backlight time settings
- Overload protection: When the power of the appliance exceeds the overload power, the LCD will display “OVERLOAD” to warn the user. All the buttons will quit working and can only be workable when you lower or remove the load power. The default overload power is 3680W and is adjustable from 0 to 3680W. In general, you need to set the overload power to 1800W before using. Just press the "function" button for more than 3 seconds to enter the setting
- Data Memory Function: The wattage meter will record your power consumption data when you remove it from socket, or remove appliances from the electricity monitor. You can directly see the last data when you use it next time. This function can also automatically save the data when there is a sudden power failure
No current primary controlled measurement for a representative Windows PC playing YouTube is established here. For a useful estimate of your own equipment, a wall measurement is more relevant than applying an old reference figure.
Turn kWh into an India-specific bill estimate
Multiply the estimated kWh by the applicable energy rate on your electricity bill or your utility’s current tariff schedule. There is no supportable single India-wide monthly rupee amount: retail rates depend on the state, distribution utility, consumer category, slab, and current tariff. The Press Information Bureau, Government of India, states that “Electricity tariffs in India are determined by the Appropriate Electricity Regulatory Commissions under the Electricity Act, 2003.”

A utility calculator is useful only for its own service area and tariff basis. For example, WBSEDCL’s Energy Cost Estimator calculates energy cost from watts and says it uses the latest tariff order passed by WBERC; it is not a national tariff calculator. Your total household bill may also include fixed charges, duties, subsidies, or slab effects, so multiplying all usage by one simple rate may not match the bill impact.
Windows settings: playback versus sleep
Windows 11 provides power-mode options and screen and sleep timeouts. Microsoft’s power settings guidance explains that a screen timeout turns off the screen after inactivity, while a sleep timeout puts the device to sleep. A PC that must continue playing video cannot sleep during that playback period. If you only need audio, turning off the display may reduce display use, but the amount saved is not established; measure it on your setup.

Microsoft also notes that some supported apps can use lower resolution to save network bandwidth in its video playback settings guidance. That does not establish an electricity saving for YouTube on a Windows PC, so treat lower resolution as a bandwidth choice rather than a guaranteed power reduction.

Keep playback running, or keep a YouTube live stream running?
Playing a YouTube video continuously on your Windows PC is different from operating a live-stream encoder or server. If your goal is instead to keep a pre-recorded video live on a YouTube channel, StreamNeo is a separate cloud option: upload a recording or build a playlist, add your YouTube stream key, and go live. It runs without a home computer staying on, streams uploaded video to YouTube, and automatically recovers if YouTube drops the stream. StreamNeo charges one flat price per slot for any uploaded quality up to 4K 60fps; the first day is free with no card. See StreamNeo for details.
