There is no single monthly electricity cost for running a PC with a children’s stream 24/7 in India. Work it out from the PC’s average AC wall draw, then apply the tariff and slab rules on your household bill.
For a clear arithmetic illustration, a steady 50 W draw uses about 36 kWh in a 30-day month, while 100 W uses about 72 kWh. Both are hypothetical scenarios, not measurements or claims about typical PC consumption; a power-supply rating is not the PC’s average draw.
Start with the draw at the wall
The number you need is the power actually drawn from the mains while the stream is running. A plug-in energy monitor can show watts at a moment in time and, on some models, accumulated kWh over a period. Use a meter suitable for the outlet and load, and follow its instructions. A momentary reading may miss changes during playback, so an accumulated reading over a representative session is more useful.
Measure the setup in the state you intend to leave it overnight: the same video or playlist, playback method, encoding arrangement, and background tasks. A PC can draw differently when it is idle, playing video, encoding, or handling other work. If the stream uses a display, include it in the measurement only if you want its contribution included in the bill estimate. Apply the same rule to speakers, external drives, or other equipment.
ENERGY STAR’s computer guidance distinguishes operating states such as idle, sleep, and off, and its testing material concerns power from an AC source. That distinction matters here: a PC merely switched on is not necessarily drawing the same power as one actively processing a stream. See ENERGY STAR’s computer information for context on computer power and operating states.
Avoid treating the wattage printed on a power supply as the reading. That rating describes the supply’s capacity under specified conditions, not the continuous amount the PC takes from the wall. A supply rated for a certain maximum does not mean the machine consumes that many watts throughout the day. The monitor, peripherals, workload and efficiency also affect what the wall meter sees.
An old ENERGY STAR stakeholder test annex and historical specification include desktop examples, but they are not a measurement of your current machine running your particular stream. They should not be used to label 50 W or any other figure as a universal or typical draw. Your own wall-side reading is the relevant input; where you cannot measure, use several clearly labelled scenarios rather than presenting a guess as fact.
Turn watts and runtime into monthly units
Electricity bills commonly express energy in kWh, or units. Convert average watts to kilowatts by dividing by 1,000, then multiply by the hours the equipment runs. For a continuous stream over a 30-day illustration, that is 24 hours per day multiplied by 30 days, or 720 hours.
The calculation is:
Monthly kWh = average wall watts ÷ 1,000 × 24 × 30.
This formula assumes a steady average draw and a 30-day month. If a meter gives you accumulated kWh directly for a measured period, that reading can avoid the need to estimate an average watt value. For a period shorter or longer than a month, scale by the actual number of days, or compare equivalent periods rather than assuming every billing month has the same duration.
A useful check on the arithmetic is that every 30 W of continuous average draw corresponds to 0.72 kWh a day, or 21.6 kWh across 30 days. That relationship is just unit conversion, not a prediction about a particular PC. It can help you spot a misplaced decimal when using a meter reading or spreadsheet.
For example, enter the measured average wall watts into the formula and keep the result in kWh until you have checked how your household is billed. Do not multiply watts directly by a rupee-per-unit tariff: watts measure power, while the bill charges for energy used over time. Also check whether the bill’s units represent kWh, and whether the period being compared is a complete billing cycle.
For a recorded-video channel, the content loop is only one part of the running setup. You may find it useful to compare the electricity question with the separate operating choices in how to run a 24/7 YouTube stream with prerecorded videos on Google Cloud Run, while keeping this calculation focused on the equipment and tariff you actually use.
Apply the tariff that your household actually pays
There is no national household unit rate that can be plugged into every Indian electricity estimate. Rates and billing rules depend on the state or territory, distribution company, domestic tariff category, consumption slab, and any applicable subsidy or adjustment. The Ministry of Power states that tariffs are determined by the appropriate Electricity Regulatory Commissions under the Electricity Act, 2003. You can read its official explanation of tariff determination.
Look at a recent bill for the DISCOM, tariff category, units consumed, and the energy-charge lines. Then check the current official tariff schedule for that provider and category. The rate applying to an added unit can depend on how much the home already uses: if adding the PC’s energy moves the household into a higher slab, part of that additional use may be charged at a higher marginal rate. A single rate multiplied by every extra unit may therefore be a poor estimate.
The practical calculation is to compare the energy charge with and without the PC’s added kWh, using the applicable slab rules. If the bill or tariff schedule is unclear, ask the DISCOM how the category, slabs and subsidy apply to your connection. Do not assume the tariff of a neighbouring state, a commercial connection, or a published example applies to your domestic bill.
As one explicitly limited example, the Department of Electricity, Lakshadweep lists FY 2026–27 normal domestic energy charges of ₹3.55 per kWh for the first 100 units, ₹5.30 for 101–200, ₹7.70 for 201–300, ₹10.05 for 301–400, and ₹13.05 above 400, plus a fixed charge of ₹25 per kW per month, as listed on its site in October 2026. This is one official schedule, not a national rate. Its tariff page is where to check the schedule and its applicability.
Two transparent scenarios, not PC benchmarks
The following figures assume a constant draw for all 720 hours of a 30-day month. The rupee ranges show only the energy charge calculated by multiplying the scenario’s monthly kWh by the lowest and highest Lakshadweep rates above. They do not model a particular household’s slab crossing, fixed charge, subsidy, duty, or other bill components. The rates are Lakshadweep’s FY 2026–27 normal domestic rates, as listed on its site in October 2026.
| Hypothetical average AC wall draw | Monthly energy at 720 hours | Energy-charge illustration at ₹3.55–₹13.05/kWh |
|---|---|---|
| 50 W | 36 kWh | About ₹128–₹470 |
| 100 W | 72 kWh | About ₹256–₹940 |
The 50 W row is the calculation 0.05 kW × 720 hours; the 100 W row is 0.1 kW × 720 hours. Neither row says that a PC running a children’s stream typically draws that amount. They are useful because they show how the same simple method changes when the assumed average draw doubles. Replace the assumed watts with your measurement and the sample rate with the relevant marginal rate for your home.
The ranges are deliberately broad because applying only the lowest or only the highest slab rate to every unit is a simplified illustration, not a full bill simulation. A household’s incremental charge may cross slabs, while some charges may be fixed or calculated differently. If the household is already close to a slab boundary, the additional kWh can affect which rates apply. Use the bill’s actual tariff rules for a more defensible result.
This is why one rupee estimate cannot represent every Indian household. Two homes with the same PC reading can pay different added amounts because their tariff categories, consumption, subsidies and bill components differ. Even within one home, the PC’s measured draw can change if the workload, attached display or operating state changes.
Include fixed charges and household adjustments carefully
The energy charge is not necessarily the whole bill. Bills can also contain fixed or demand-related charges, duties, fuel adjustments, and subsidies or other adjustments, depending on the tariff. Some of these do not increase in direct proportion to the PC’s added kWh. Avoid taking the whole bill total, dividing by total units, and assuming that average rupees per unit will precisely price one extra device: fixed amounts and slab structures can distort that average.
For a household estimate, first determine the incremental energy charge under the schedule, then consider which other line items are variable and applicable to your connection. If a duty is calculated on energy charges, it may rise with those charges; if a fixed monthly charge is based on sanctioned load, the PC’s use may not change it. The bill and official schedule, rather than a generic online estimate, are the right references.
Subsidies can make a material difference to the effective amount payable, and their eligibility or calculation may depend on consumption or connection details. Do not assume a subsidy applies simply because it is available in a state or for another category. The Central Electricity Authority’s financial studies and tariff resources are useful background, but your DISCOM’s current schedule and your own bill determine the household calculation.
If you want a comparison between two setups, measure them under the same stream and playback conditions, and decide consistently whether to include the display and peripherals. Compare the measured kWh difference, then apply your own tariff rules to that difference. This isolates the hardware change without pretending that another household’s bill provides a transferable price.
Consider changes without assuming savings
Reducing unnecessary load may reduce electricity use, but the result depends on what the setup is doing and how long it runs in each state. Turning off a monitor that is not needed, removing unused peripherals, or using a lower-power playback device may change the total draw. There is no reliable rupee saving to claim without measuring the change and applying the household’s tariff.
If the PC is encoding video locally, compare the wall draw with the actual playback arrangement you need. Moving a task elsewhere does not automatically reduce the household’s total energy use; it may simply shift where the energy is consumed. For a 24/7 channel, the decision may also involve control, maintenance, reliability and the cost of equipment, not just electricity. Keep those questions separate rather than treating lower watts as the only objective.
A cloud-based broadcast can remove the need to leave your own computer running for the stream, which is useful if that specific overnight PC load is the pain you are trying to remove; StreamNeo turns an uploaded video into a YouTube-only 24/7 broadcast without keeping your computer on. It does not establish your remaining household energy use or eliminate the need to check your content, channel and tariff decisions. If your stream depends on a locally operated workflow or other applications, retaining a PC may make more sense.
You can also review the operational trade-offs in how to live stream recorded videos on YouTube 24/7 using a Raspberry Pi. The point is not that one device will always cost less, but that measured wall draw under the intended workload gives you a comparable input. A device’s advertised capability or component rating does not substitute for a reading at the wall.
Recalculate from readings and bills
A useful estimate can be made in a few careful steps. First, record average watts or accumulated kWh with the stream running in its normal state. Make a note of whether the meter includes the display and other devices. If the reading varies, use a representative period that covers ordinary playback rather than choosing a brief low point.
Second, convert the reading to the same period you want to compare. If the meter shows average watts, use watts ÷ 1,000 × 24 × number of days. If it reports kWh over a measured interval, scale that kWh by the ratio of the target period to the test period, while recognising that scaling assumes the test period represents normal use. A 30-day calculation is a convenient comparison, not a claim about the exact length of your billing cycle.
Third, note the units and tariff category on your bill, and check the current official schedule for your DISCOM. Estimate the added energy charge using the slab that applies to the household’s total consumption, not just the PC’s separate kWh. Include only relevant variable charges and subsidy effects that you can verify. If you cannot tell how the slabs interact, present the energy use in kWh and ask the provider for clarification rather than forcing a precise rupee answer.
You can then update the estimate when the stream setup changes or the household moves into a different billing pattern. Save the wall reading and the bill period together, so a later comparison uses equivalent conditions. This is more informative than reusing an old cost estimate after changing the playback device, monitor, stream workload or tariff.

FAQ
Does a PC’s power-supply rating tell me its monthly electricity use?
No. The rating describes the power supply’s capacity, not the PC’s average AC draw from the wall while streaming. Measure the complete setup during representative playback, then convert that wall-side reading to kWh.
How many units would 50 W use in a 30-day month?
If 50 W were a constant average wall draw for 720 hours, it would use 36 kWh. That is a hypothetical calculation, not a typical-PC claim or a measurement of your setup.
Can I use the Lakshadweep rate for my home elsewhere in India?
Only if that tariff actually applies to your connection. State or territory, DISCOM, category, slab, subsidies and other bill items vary, so check your own current bill and official tariff schedule.
Should I count the monitor in the estimate?
Count it if you want the combined bill impact of the equipment left running. Measure it as part of the setup, or measure it separately and add its energy use; keep the same inclusion rule when comparing alternatives.
