An eight-hour PC session has no single electricity cost: it depends on the setup’s average power at the wall and the marginal energy rate that applies to your household. Work out the energy in kWh first, then multiply by that local rate to estimate the session’s energy charge—not your exact bill.
For example, a setup drawing an illustrative average of 300 W for eight hours uses 2.4 kWh. At the Central Electricity Authority’s published domestic average billing-rate reference of ₹6.34/kWh, that arithmetic comes to about ₹15.22; your own rate, slab, subsidy and bill adjustments may produce a different figure.
Why an eight-hour cost varies
The duration is only one part of the calculation. A gaming PC does not necessarily draw the same power throughout a session: the game, graphics settings, frame rate, processor and graphics card workload, encoding, and other activity all affect the draw. A demanding game scene may use more power than a menu or a lighter workload. There is no universal wattage that describes every PC used for a YouTube gaming VOD stream.
The equipment boundary matters, too. A reading for the tower alone does not include a monitor, speakers, router, capture device or other accessories unless they are connected through the meter. A laptop’s power use can also change when you add an external display or dock. Decide which equipment you want to count before comparing estimates or sessions.
A VOD stream can mean that you are broadcasting a previously recorded gaming video, or recording gameplay now to publish later. In either case, this estimate concerns electricity used by the equipment running during the eight-hour window. It does not calculate upload data, YouTube processing, or the energy used to create the video before that session.
If you are comparing approaches, keep the duration and included equipment the same. Comparing a tower-only reading with a laptop-and-monitor reading does not tell you which whole setup used less energy. The OBS playlist source setup for continuous YouTube streaming is relevant if a prerecorded video is being played continuously, but this cost calculation still depends on the equipment drawing power at your end.
Measure average power at the wall
The most useful input is the setup’s average wall power during the session, not the power-supply rating printed on the PC’s components. A suitable plug-in electricity meter that records accumulated energy in kWh can measure the equipment connected to it. If you want the whole desk setup, connect the equipment you mean to count through the meter, while staying within its rated capacity and using it as directed.
Run a representative session: use the game, stream or recording software, settings, and peripherals you normally use. Record the meter’s kWh reading at the beginning and end. The difference is the energy used over the measurement period. If you instead have a meter that shows only instantaneous watts, a reading taken at one moment may miss the changes during gameplay, encoding and idle periods.
The U.S. Department of Energy’s guidance on measuring power use over time explains the principle: where consumption fluctuates, measure energy over a period and divide by that period to find average power. For a full eight-hour session, average watts can be calculated as measured kWh × 1,000 ÷ 8. A meter that already records the session’s kWh lets you skip the watts conversion and go directly to the rate calculation.
For a useful comparison, measure the same set of equipment and a similar workload on each occasion. A gaming session with the monitor off is not comparable with one where the monitor and speakers are included. If you want to know the PC’s contribution alone, place only the PC on the meter; if you want to budget for the streaming desk, include the devices that will actually stay on.
Calculate energy for eight hours
The conversion is straightforward:
Energy used (kWh) = average wall power (watts) × 8 hours ÷ 1,000
The division by 1,000 converts watt-hours into kilowatt-hours. A kilowatt-hour is the unit normally used to bill household electricity. It is sometimes called one “unit” on an Indian electricity bill, so 2.4 kWh is 2.4 units of energy.
For example, if the average wall draw is 300 W, then 300 × 8 ÷ 1,000 = 2.4 kWh. The 300 W is an input assumption in this example, not a claim about a typical gaming PC. Substitute your own measured average wattage, or use the session’s meter-recorded kWh directly.
For a different duration, replace eight with the number of hours measured. To estimate a weekly total, first find the energy for one representative session, then multiply by the number of sessions you actually run. Keep the result in kWh; apply the relevant energy rate only after establishing your consumption. That order makes it easier to spot whether a difference comes from power use or from the tariff used in the estimate.
Apply your marginal energy rate
Once you have session energy, use the rate that applies to the additional units consumed by your household. The basic calculation is:
Energy charge (₹) = session energy (kWh) × applicable marginal energy rate (₹/kWh)
The word “marginal” matters. A household tariff can be structured by consumption slabs, and the next unit may be charged differently from earlier units. Check the current tariff for your state or union territory, DISCOM and domestic consumer category, then consider where those additional units fall in the household’s billing period. If your tariff is telescopic, the estimate may involve more than one slab rather than a single rate for every unit.
Your latest bill can help identify the category and DISCOM, but it may show average charges rather than a rate suitable for this calculation. Where the bill does not make the applicable next-unit rate clear, consult the DISCOM’s current tariff schedule or bill calculator. Do not use a rate from another state simply because it appears in an example.
The Chhattisgarh State Electricity Regulatory Commission’s FY 2026–27 tariff schedule illustrates why local schedules matter. As listed in that schedule, domestic energy charges include ₹4.50/kWh for the 101–200 unit slab and ₹8.80/kWh above 600 units. Those are Chhattisgarh examples, not rates for all Indian households; check the current official schedule for your own connection.
Three illustrative eight-hour cases
The table keeps the assumptions visible. The draw figures are illustrative average wall-power inputs for the PC and any peripherals you choose to include; they are not measured results for a particular gaming PC. The energy figures follow the eight-hour formula, and the rupee figures use the CEA reference rate discussed below.
| Illustrative average wall draw | Energy in eight hours | Energy charge at ₹6.34/kWh |
|---|---|---|
| 100 W | 0.8 kWh | ₹5.07 |
| 300 W | 2.4 kWh | ₹15.22 |
| 500 W | 4.0 kWh | ₹25.36 |
These are arithmetic examples, not quotes for a PC or predictions of a household bill. They do not establish that a gaming PC will draw 100 W, 300 W or 500 W on average. The machine and workload could differ, and the included equipment could change the measured draw. Replace the assumed watts and the reference tariff to make the calculation relevant to your situation.
To use the 300 W row with a local marginal rate of your own, keep the 2.4 kWh figure and multiply it by that rate. For instance, if the applicable rate you have verified is R rupees per kWh, the session’s energy charge is 2.4 × R rupees. This leaves the rate as a variable rather than silently treating a national reference or another state’s slab as your own.
If you have measured the setup over the full eight hours, use the meter’s kWh result instead of selecting a row. That one reading accounts for the actual combination of idle time, gameplay and streaming or recording in your session, although another session with a different workload may use a different amount.
What the CEA reference rate means
The Central Electricity Authority’s 2025 publication, Electricity Tariff & Duty and Average Rates of Electricity Supply in India, includes a Domestic average billing-rate entry of ₹6.34/kWh. It is useful here as a clearly identified reference for the sample arithmetic, not as a tariff assigned to every household. CEA’s tariff publication organises information by state or union territory, DISCOM and consumer category, which is a better starting point when identifying the context of a listed rate.
An average billing-rate reference is not the same as the next unit’s marginal energy charge on your bill. It cannot tell you by itself which slab applies, whether a subsidy changes your payable amount, or what other charges and adjustments appear on your account. That is why ₹15.22 in the 300 W example is the product of 2.4 kWh and ₹6.34/kWh, not an exact bill estimate for a named household.
Use the CEA figure when you want to reproduce the examples in this article. Use your own current DISCOM tariff when you want a better household estimate. The two calculations answer different questions: one makes examples comparable; the other tries to reflect the price attached to the additional energy at your location and consumption level.
Energy charge is not the whole bill
The multiplication above estimates the energy charge associated with the session’s kWh at the selected rate. A household electricity bill can include fixed charges, duties, adjustments, taxes or other components under its applicable tariff and billing rules. Some of these can affect the total bill, but they are not necessarily caused by one additional eight-hour session. Do not add the whole fixed charge to this session as if the PC created it.
Subsidies can also affect the amount a household pays, subject to the local rules and the consumer’s eligibility. Slab thresholds and billing-period consumption may change which energy rate applies to additional units. Your bill’s total divided by total units may be a useful rough average, but it should not be mistaken for the marginal rate if the tariff is slab-based or the bill includes non-energy items.
For budgeting, keep two figures separate: the estimated energy charge from the formula, and the eventual household bill total. If you are checking why the bill changed, compare billing periods with similar durations and equipment use, then review the tariff and any bill adjustments. A single session estimate can explain its likely energy contribution; it cannot account for every reason two monthly bills differ.
The same distinction helps when deciding whether a change is worthwhile. If a monitor or accessory stays on during the session, measuring it with the PC can show its contribution to the setup’s kWh. If your bill includes a fixed charge regardless of that session, turning off the PC may reduce the energy component without removing that fixed amount. The actual bill treatment depends on the current tariff and your account.
Choose a practical setup for repeated streams
If the channel runs only for a planned eight-hour session, measuring one representative session may be enough for a working estimate. If it runs regularly, record the setup’s kWh across a few sessions with the same equipment and similar use. That gives you a practical baseline without claiming that every gaming workload is identical. Keep notes on whether the monitor, router, speakers and capture equipment were included, so the comparison remains meaningful.
If electricity use is a concern, first confirm what is actually running. A PC rendering gameplay, encoding a stream and driving a display may draw differently from a PC simply playing an already recorded video. You can measure both approaches rather than assume that one is always lower. For a prerecorded loop, the guide to running a 24/7 Indian music YouTube stream from MP4 files offers a related playback context, while the electricity calculation still comes from your own measured equipment and local rate.
The length of the video loop is a separate issue from power draw. If you need a repeatable recording or want to retain a copy, the article on recording a YouTube livestream covers that task; it does not supply a wattage assumption for your setup. Keep the cost estimate grounded in a wall measurement rather than in a software feature, component label or an unverified “typical” PC figure.
For a channel that needs to keep broadcasting while your home computer is switched off, StreamNeo removes the specific burden of leaving that PC running for the broadcast: upload the video and use your YouTube stream key to run it as a continuous YouTube stream. That changes which equipment needs to stay on at your end; it does not establish a guaranteed electricity saving or change how your household tariff is calculated.

FAQ
How many units does a PC use in eight hours?
It depends on the average wall draw and on which peripherals are included. At an illustrative 300 W average, eight hours uses 2.4 kWh, or 2.4 units; use a meter reading for your own setup rather than treating that assumption as universal.
How do I calculate the electricity cost for my PC?
Multiply average wall watts by eight hours and divide by 1,000 to get kWh. Then multiply the kWh by the marginal energy rate that applies to your household; the result estimates the energy charge, not necessarily the full bill.
Is ₹6.34 per unit the rate for every home in India?
No. It is the CEA publication’s Domestic average billing-rate reference used for the examples, not a universal household tariff. Your state or union territory, DISCOM, category, consumption slab and subsidy can affect the applicable rate and payable amount.
Will the cost include my monitor and router?
Only if they are included in the power measurement or assumed average draw. Put the equipment you want to count through a suitable energy meter during a representative session, and use the resulting kWh with your local marginal rate.
