A continuous 20 W load uses 0.48 kWh each day, 14.4 kWh in 30 days, and 175.2 kWh in 365 days. To estimate its electricity cost, multiply the relevant kWh figure by the applicable energy rate on your own bill; these figures are not a national price estimate.
The 20 W figure is an assumption for the calculation, not a claim about what a particular mini PC draws while streaming. Indian household tariffs vary by state, distribution utility, consumer category, slab and subsidy, so use your own tariff and, if possible, replace the assumption with a measurement at the wall.
What the 20 W assumption means
A watt is a measure of power at a moment in time. For this estimate, 20 W means the computer and its power supply together are assumed to draw an average of 20 watts continuously while the stream runs. The calculation does not establish that any particular model, configuration or streaming workload uses that much.
A mini PC’s draw can change with its processor, video encoding, peripherals, power supply and workload. A screen, router, audio equipment or separate storage device may add to the electricity used by the full streaming setup. Conversely, equipment not needed during an unattended broadcast can be switched off and left out of the estimate.
Keep the boundary consistent. If you are asking only what the computer adds to the bill, measure or estimate the computer and its power supply. If you want the whole room’s streaming cost, include every device that must stay on. The answer changes with that choice.
This is an electricity-use calculation, not a YouTube requirement or a device recommendation. For the wider question of whether a prerecorded file can be run continuously, see the practical options in how to schedule a prerecorded playlist to loop on YouTube Live. That decision is separate from the watts your equipment draws.
Calculate daily kWh
Electricity bills commonly express energy in kilowatt-hours, or kWh. One kWh is the energy used by a 1,000 W load running for one hour. To convert a continuous load from watts into kWh, multiply watts by hours and divide by 1,000:
average watts × hours ÷ 1,000 = kWh
For the assumed load, the daily arithmetic is:
20 W × 24 hours ÷ 1,000 = 0.48 kWh per day
The 24 hours represent a full day with the assumed load running throughout. This is a derived calculation, not a measured result. If the computer is powered down for part of a day, use its actual running hours. If its average draw is not 20 W, substitute your measured or otherwise well-supported average.
For example, the formula lets you compare two possible arrangements without relying on the label attached to a computer. Put each arrangement’s average wall watts and operating hours into the same equation, then compare the resulting kWh for the same period. Keep the included devices and operating hours consistent so the comparison is useful.
Calculate 30-day and annual kWh
Starting with 0.48 kWh per day, the exact period calculations are:
- 30-day period: 0.48 kWh × 30 days = 14.4 kWh.
- 365-day year: 0.48 kWh × 365 days = 175.2 kWh.
The 30-day result is a convenient comparison period, not necessarily the number of days in your billing cycle. For a bill covering a different number of days, multiply 0.48 kWh by that number, or calculate directly from your measured watts and actual hours. A leap year has an extra day; for a 366-day period at the same assumed load, the calculation would be 0.48 × 366 rather than the 365-day figure.
The arithmetic scales linearly. If actual average draw is higher or lower than 20 W, the kWh changes in the same proportion when operating hours stay fixed. It is often clearer to correct the watts first than to make a rough adjustment to the cost at the end.
| Period | Calculation at assumed 20 W | Energy used |
|---|---|---|
| One day | 20 × 24 ÷ 1,000 | 0.48 kWh |
| 30 days | 0.48 × 30 | 14.4 kWh |
| 365 days | 0.48 × 365 | 175.2 kWh |
Use the monthly figure when considering the next bill and the annual figure when comparing the ongoing energy use of a setup. Neither figure includes a tariff, a fixed charge or any other bill component.
Apply your applicable electricity tariff
For a first estimate of the energy-charge component, multiply the kWh used by the energy rate that applies to your household’s additional consumption. At a flat rate, the operation is simple: 14.4 kWh × your rate per kWh gives the 30-day energy-charge estimate. Use the tariff and billing period that actually match your connection rather than treating a rate found for another state or consumer as yours.
If your bill uses consumption slabs, the extra 14.4 kWh may fall partly or wholly into a particular slab. Your marginal rate for those units may therefore differ from the average rate you get by dividing the full bill by total kWh. Check the current tariff schedule for your category and the consumption level that applies. Also check whether the amount you are using is an energy charge per unit rather than a figure that bundles other bill items.
A local illustration shows why location matters. The Department of Electricity of the Union Territory of Lakshadweep lists, for FY 2026–27, LTDS-II domestic energy rates of ₹3.55/kWh for 0–100 units, ₹5.30 for 101–200, ₹7.70 for 201–300, ₹10.05 for 301–400, and ₹13.05 above 400 units. At the first listed energy rate, 14.4 kWh × ₹3.55/kWh = ₹51.12 in energy charges for the 30-day example. This is Lakshadweep arithmetic, not an estimate for India as a whole or a prediction of a household’s complete bill.
At the other listed Lakshadweep energy rates, the same 14.4 kWh multiplication gives ₹76.32 at ₹5.30, ₹110.88 at ₹7.70, ₹144.72 at ₹10.05, and ₹187.92 at ₹13.05. These are illustrative energy-charge calculations only. The schedule also lists a fixed charge of ₹25 per kW per month or part thereof, and a real bill can have fixed charges, other local components and subsidy treatment. Do not add or interpret those items without checking the bill and applicable schedule.
The practical method is to find the current schedule for your utility and domestic category, identify the relevant slab or marginal rate, and multiply by the added kWh. Then compare that energy-only result with the matching period on your bill, noting fixed charges and adjustments separately. If unsure which rate applies, ask your distribution utility rather than assuming an online example is a national benchmark.
Why Indian household rates vary
India does not have one household electricity unit price that can responsibly be inserted into this calculation. The Ministry of Power says retail tariffs are determined by the appropriate State Electricity Regulatory Commissions, and state governments may provide subsidies to consumer classes, including domestic consumers. The applicable result can therefore depend on where the connection is, which utility serves it, the consumer category and the household’s consumption.
A state tariff schedule may set different rates at different consumption levels. A subsidy can also affect what a domestic consumer pays. Fixed charges and other bill components mean that multiplying kWh by a listed energy rate is not necessarily the same as calculating the total bill. The calculation here deliberately isolates the incremental energy use of the assumed streaming load.
The official Ministry of Power statement published by the Press Information Bureau is a useful starting point for the tariff framework. For the numbers in the local illustration, consult the Lakshadweep Department of Electricity tariff schedule and confirm the current schedule and category that apply to you. An example from one territory is useful for showing the arithmetic, but not for inferring the rate in another place.
When comparing two homes or two operating options, compare like with like: average measured watts, hours, tariff category, relevant slab, subsidy treatment and the same billing period. Comparing one person’s energy-only estimate with another person’s complete bill can make a small load appear misleadingly cheap or expensive.
Replace the assumption with measured watts
The most useful improvement is measuring the equipment under the conditions in which you intend to run it. A plug-in electricity usage monitor that reports watts or kWh can help show what a connected device uses. ENERGY STAR’s home energy management criteria describe plug-load monitors and home energy monitors capable of reporting power or energy consumption. That source describes a category of monitoring capability; it is not a recommendation for a particular model or a claim about local availability.
If you use a monitor, connect the computer and its power supply as you would for the stream, then observe consumption during representative operation rather than relying only on a startup reading or a product label. A stream’s file, encoding choices and connected equipment can affect the load. If the monitor provides accumulated kWh over a period, that can be a useful cross-check on an average-watts estimate, provided you record the period and what was plugged in.
Use the measured average in the same formula: average watts × hours ÷ 1,000 = kWh. For a full day, multiply average watts by 24 and divide by 1,000; for a 30-day estimate, multiply the daily figure by 30. If the measurement includes a monitor or other device that will not remain on, remove it from the setup before measuring or account for it separately.
You do not need to buy a monitor just to get a rough estimate. If you can only find a power rating, treat it as a reference rather than a verified streaming draw and label the result as an estimate. The point is not to chase a perfectly precise number; it is to know whether your calculation represents the computer alone or the actual always-on arrangement.
Check the full streaming setup
Electricity is one part of an always-on channel’s operating choice. A computer-based workflow gives you control over the files and encoding, but it also means the computer and any necessary peripherals need to remain available. Check which items genuinely need power overnight: perhaps the mini PC and network equipment, rather than a display, keyboard lighting or speakers. Measure the arrangement you will actually leave on.
The stream also depends on suitable video and a stable workflow. If a playlist contains files with differing dimensions, the guide to batch resizing videos to 1920×1080 for a YouTube playlist stream can help you prepare a consistent set of sources. For a computer running OBS, the OBS settings for a 24/7 ocean waves stream offer a separate reference for configuring a continuous broadcast. Neither topic changes the arithmetic for kWh, but both affect what the practical setup includes and how you assess it.
A final comparison should include measured average wall draw, expected hours, the local marginal tariff and the effort involved in keeping the broadcast running. If leaving a computer on is the particular pain point, StreamNeo removes the need to keep your own computer on by turning an uploaded video into a 24/7 YouTube live stream. Decide based on the workflow you need, and keep electricity calculations for equipment you actually operate separate from other service costs.

FAQ
How much electricity does a 20 W load use in a day?
At a continuous assumed draw of 20 W, the calculation is 20 × 24 ÷ 1,000, or 0.48 kWh per day. It is an arithmetic estimate, not a test result for a particular mini PC.
What is the 30-day and annual electricity use?
The assumed load uses 14.4 kWh over 30 days and 175.2 kWh over 365 days. For a different operating period, multiply the daily 0.48 kWh by the number of days.
How do I calculate the cost in my state?
Use the tariff schedule for your own utility, consumer category and consumption slab, then multiply the relevant energy rate by the added kWh. Treat that as an energy-charge estimate and check fixed charges, subsidies and other bill items separately.
Does every mini PC draw 20 W while streaming?
No. Twenty watts is the assumption used for this calculation, not a claim about a specific computer or workload. Measure the actual setup if you need a better estimate, then substitute its average watts in the formula.
