A laptop running a 24/7 YouTube stream may use less electricity than its charger rating suggests, but the only dependable starting point is its average power draw at the wall. If that average is 20–60 W, continuous use over a 30-day month works out to 14.4–43.2 kWh.
Using the Chandigarh domestic energy-charge rates listed in a Central Electricity Authority compilation as an illustration, those amounts would produce roughly ₹40–₹233 in energy charges. That is not a national monthly bill or a complete bill prediction: your tariff, slab, fixed charges, duties, adjustments and subsidies may all change the result.
Why the charger wattage is not the measurement
The number printed on a laptop charger describes the maximum output the charger is designed to provide under its rating conditions. It does not say that the laptop continuously draws that amount while playing a prerecorded video and sending it to YouTube.
A charger marked 65 W, for example, may have enough capacity for the laptop to run, charge its battery and handle a demanding workload. During ordinary playback, the computer may draw less. At another point, screen brightness, processor activity, charging behaviour, connected devices, network activity or background updates may raise the draw.
The relevant measurement is the electricity taken from the wall by the complete setup. That means the laptop, charger and any directly related equipment included in the test. Measuring only the charger label would confuse a capacity figure with consumption.
This distinction matters particularly for an always-on channel. A short observation while opening a browser may not represent a full day of playback. Nor should you turn a battery-life claim into a wall-power estimate. Microsoft explains that battery performance varies with settings, usage and other conditions in its Surface battery testing guidance.
If you have not measured the machine yet, use several clearly labelled assumptions rather than presenting one wattage as a fact. The examples later in this article use 20 W, 40 W and 60 W only as transparent calculation inputs. They are not published averages for laptops streaming YouTube in India.
Measure average power at the wall
A plug-in electricity usage meter or a compatible energy-monitoring smart plug can show how much power the setup draws at the socket. The useful figure is the average watts over representative playback, not the highest momentary reading.
Connect the laptop and charger through the meter, then run the same type of stream you expect to operate continuously. Use the normal display brightness, audio arrangement, network connection and playback method. If the laptop will normally stay plugged in, measure it while plugged in. If you will attach a monitor, speaker, cooling pad or other equipment that is part of the streaming setup, decide whether those devices belong in the same measurement and keep that choice consistent.
A brief reading can be misleading. Let the machine play for a representative period that includes ordinary fluctuations, then record either the meter’s average watts or its accumulated kWh. The longer and more realistic the observation, the less likely it is that a temporary update, battery charge cycle or unusual background task will dominate the result.
You can also take separate readings for different operating conditions. For example, measure with the screen on at its normal brightness, then measure with the screen configured to remain off if that is suitable for your setup. Do not assume the lower reading is automatically appropriate if the machine needs to stay awake, display status information or support another local task.
Windows settings can affect energy use. Microsoft identifies power mode, energy saver, brightness and screen or sleep settings as relevant controls in its guidance on power settings in Windows 11. These settings do not provide a universal streaming wattage, but they help explain why two laptops can produce different readings.
If the meter reports kWh directly, you can use that figure for the measured period and scale it carefully to the billing period. If it reports only watts, use the average reading in the formulas below. Keep a note of what was included, because a laptop-only number and a laptop-plus-monitor number answer different questions.
Calculate the energy for 24/7 use
A 30-day month contains 720 hours. Once you have an average wall draw, the arithmetic is straightforward:
- Daily energy (kWh) = average wall draw (W) × 24 ÷ 1,000
- 30-day energy (kWh) = average wall draw (W) × 720 ÷ 1,000
- Energy-charge estimate = kWh × applicable marginal energy rate (₹/kWh)
The conversion from watts to kilowatt-hours is important. A watt is a rate of power at a particular moment. A kilowatt-hour, often called a unit of electricity, measures energy accumulated over time.
There is a useful shortcut for this particular period: each 1 W of average draw corresponds to 0.72 kWh over 720 hours. A measured average of 35 W would therefore be 25.2 kWh for a 30-day month before any tariff calculation. That is an arithmetic relationship, not a claim about how much a particular laptop uses.
Here are three assumptions to show the method:
| Assumed average wall draw | Energy per day | Energy per 30 days | Energy charge at ₹2.75/kWh | Energy charge at ₹5.40/kWh |
|---|---|---|---|---|
| 20 W | 0.48 kWh | 14.4 kWh | about ₹40 | about ₹78 |
| 40 W | 0.96 kWh | 28.8 kWh | about ₹79 | about ₹156 |
| 60 W | 1.44 kWh | 43.2 kWh | about ₹119 | about ₹233 |
For example, at 40 W, the daily calculation is 40 × 24 ÷ 1,000, which gives 0.96 kWh. Over 30 days, 40 × 720 ÷ 1,000 gives 28.8 kWh. The final column depends on which applicable marginal rate you are using; it is not a complete household bill.
The same method works for fewer hours. If the laptop runs for 12 hours a day, use 12 rather than 24 and multiply by the number of days in the billing period. If your billing period is not 30 days, use its actual number of days. For a longer-running channel, however, a 30-day comparison is often easier to understand.
Apply the illustrative Chandigarh energy charges
The rates in the table come from the Chandigarh domestic schedule shown in the Central Electricity Authority’s Electricity Tariff & Duty and Average rates of electricity supply in India compilation, published in 2025. The schedule is shown as effective from 1 August 2024 and lists energy charges of ₹2.75 per kWh for 0–150 kWh per month, ₹4.80 per kWh for 151–400 kWh, and ₹5.40 per kWh above 400 kWh.
You can inspect the underlying CEA tariff compilation rather than treating the table as a universal Indian rate. The schedule is a particular domestic-tariff illustration, and its bands relate to monthly consumption. A household’s total consumption and tariff structure determine which parts of the schedule matter.
Applying ₹2.75 per kWh to 14.4 kWh gives ₹39.60, rounded to about ₹40. Applying ₹5.40 per kWh to the same 14.4 kWh gives ₹77.76, rounded to about ₹78. The 40 W and 60 W rows are calculated in the same way.
These figures are deliberately narrow. They describe the energy-charge component produced by the assumed additional consumption under the selected illustrative rates. They do not say that running any laptop in India costs ₹40–₹233 per month, and they do not predict the total amount printed on a Chandigarh household bill.
There is another practical complication: the extra laptop energy may fall within a household’s existing consumption band, or it may contribute to moving total consumption into a different band, depending on the applicable billing rules. You should not choose a rate simply because it makes the estimate look lower. Use the tariff structure that applies to the consumer category and billing period.
For current policy context, the Ministry of Power’s framework for balancing electricity financial sustainability and affordability also illustrates why affordability measures and tariff treatment cannot be reduced to one nationwide number. The relevant retail rules remain a matter for the local utility, regulator and consumer category.
Understand what the estimate excludes
An energy-charge calculation multiplies added kWh by a rate. A real electricity bill can contain other components, and those components may not rise in direct proportion to the laptop’s measured energy use.
The estimate may exclude or simplify:
- fixed or monthly charges;
- electricity duty and other taxes or levies;
- fuel, power-purchase or other adjustments where applicable;
- subsidies or relief for an eligible consumer category;
- slab or band rules based on the household’s total consumption;
- meter, service or other charges shown by the local utility;
- electricity used by the router, monitor, speakers, lights or other equipment not included in the wall measurement.
Some of these items are attached to the connection rather than to each additional unit. Others can depend on the bill period or the household’s total consumption. That is why a calculated energy charge and the increase in the final bill are not always identical.
The word “marginal” is useful here. It asks what charge applies to the additional unit at the relevant point in your billing structure. It does not necessarily mean that every unit on the bill is recalculated at the highest rate. Your utility’s current schedule and bill format are the authority for that distinction.
If you are comparing a laptop with a cloud-based option, compare the right quantities. A laptop measurement may include the computer and charger but exclude your existing router. Another arrangement may change what equipment remains running at home. Electricity cost is only one operating consideration; reliability, control, content preparation and how you recover from interruptions matter as well.
For a channel that must continue while you are away, StreamNeo removes the need to leave your own laptop running: you upload the video, add the YouTube stream key, and the broadcast continues from the cloud with automatic monitoring and restart if it drops. You should still check your content rights, YouTube requirements and the service’s current terms before relying on any setup.
Use your own tariff and bill details
Start with the electricity bill for the connection that powers the streaming laptop. Note the state or union territory, DISCOM, consumer category, billing dates, total kWh and the line items used to calculate the amount. If the bill does not make the applicable rate clear, consult the utility’s current tariff schedule or the relevant state electricity regulator.
Do not borrow a rate from a friend in another city simply because both households use domestic connections. Retail tariffs and support arrangements can differ by location, consumer category and consumption level. The Central Electricity Authority compilation is useful for examining schedules, but it does not turn one schedule into an India-wide price.
Then measure the setup at the wall. If your result is 38 W on average, the 30-day energy calculation is:
38 × 720 ÷ 1,000 = 27.36 kWh
Next, apply the marginal energy rate that fits your own bill structure. If you use more than one possible rate because the slab position is unclear, show both and label them. Do not hide uncertainty by presenting a single precise rupee amount.
If you have no meter, calculate a range from several assumptions, such as the 20 W, 40 W and 60 W examples above. State that these are assumptions. The range is more honest than treating a charger’s maximum output as the laptop’s average consumption.
Keep the estimate tied to the exact use case. A 24/7 devotional video with a stable playback loop may behave differently from a channel that continually renders scenes, changes overlays or performs live processing on the laptop. A local news loop may also involve different browser tabs, storage activity or display requirements. Measure what you intend to run, not a simplified test that leaves out the important work.
Check the result against your usage
After one billing period, compare the measured estimate with the change in your household’s actual consumption, while remembering that other appliances may have changed too. Air-conditioning, water heating, cooking, seasonal weather and occupancy can overwhelm a small laptop-related change. The comparison is therefore a check, not a controlled experiment.
A useful record contains four items: the average wall watts, the number of hours used, the resulting kWh and the tariff line applied. If the laptop is stopped overnight, record the actual schedule instead of using 720 hours. If the machine is restarted after updates or a power interruption, note the downtime because it changes energy use and channel availability separately.
You can also compare the measured wall draw before and after sensible changes. Lowering brightness, adjusting sleep behaviour appropriately and reducing unnecessary background activity may alter consumption, but verify the result at the meter. A setting that saves energy while allowing the stream to continue is different from a setting that makes the computer sleep and interrupts the broadcast.
If you use OBS or another local workflow, continuity is a separate concern from electricity. A guide on preventing OBS from stopping a YouTube 24/7 stream can help you examine the software side, while preventing gaps when switching videos addresses transitions between files. For a prerecorded library, turning existing YouTube uploads into a 24/7 live channel may also be relevant before you decide which equipment should remain powered.
The practical decision is not always “find the lowest number”. A slightly higher measured draw may be acceptable if it supports a stable workflow you can maintain. Conversely, if the laptop must remain awake, connected and supervised, the electricity estimate is only one part of the cost of operating the channel from home.

FAQ
How much electricity does it cost to run a laptop 24/7 in India?
There is no single India-wide answer because the result depends on measured wall draw and the applicable tariff. At 20–60 W, a laptop would use 14.4–43.2 kWh in a 30-day month, but the rupee amount must be calculated from your own utility’s current structure.
How many units does a laptop use in a month if it runs all day?
For a 30-day month, multiply average watts by 720 and divide by 1,000. A 20 W assumption gives 14.4 kWh, while a 60 W assumption gives 43.2 kWh; these are calculation scenarios, not typical-laptop measurements.
Can I use the wattage printed on the charger?
No. Charger wattage is a capacity rating, not a measurement of the laptop’s average draw during YouTube playback. Measure the laptop and charger together at the wall, or present several labelled assumptions if you cannot measure them.
Will streaming YouTube all day make my electricity bill high?
The laptop’s added energy may be modest, but the final bill depends on your household’s total consumption, tariff band and other line items. Check the bill or current DISCOM schedule, and distinguish the additional energy charge from the complete bill amount.
