Calculate a YouTube gaming VOD rerun’s electricity cost from your PC’s average wall-side power, the hours it runs, and your local electricity rate: cost of energy = watts × hours ÷ 1,000 × ₹/kWh. For example, an assumed 300 W average draw over four hours uses 1.2 kWh; at an illustrative ₹5/kWh, that is ₹6 in energy charges. Neither 300 W nor ₹5/kWh is a typical or nationwide figure—use measured power and the tariff that applies to your household.
Calculate the electricity used and its energy charge
First work out energy in kilowatt-hours (kWh), then multiply by the applicable energy charge per kWh:
Energy (kWh) = average wall-side watts × replay hours ÷ 1,000
Approximate energy charge (₹) = energy (kWh) × applicable marginal energy charge (₹/kWh)

“Wall-side” means power drawn by the complete PC at the socket, not the power supply’s advertised capacity. The calculation estimates energy charges; it does not necessarily predict the exact change on your full bill.

Find the right electricity rate for your household
There is no single domestic electricity rate that applies to every household in India. The Central Electricity Authority’s tariff material analyzes orders from state electricity regulatory commissions, so the applicable schedule depends on your location and consumer category. Check your bill or the current official tariff for your utility, including the relevant consumption slab. CEA tariff-and-duty publications
Why a published rate may not match your bill
A dated Chandigarh example in the CEA’s 2025 publication lists domestic energy charges effective 1 August 2024: ₹2.75/kWh for 0–150 kWh per month, ₹4.80/kWh for 151–400 kWh, and ₹5.40/kWh above 400 kWh. These are location- and date-specific figures, not current rates for all of India; verify the schedule that applies to you. CEA tariff book 2025 (PDF)

Subsidies and bill components can also affect what a household pays. For example, KPDCL presents FY 2025–26 domestic metered rates alongside subsidized rates that vary by consumption band. That utility-specific example does not establish what another utility’s customers pay. KPDCL
For a West Bengal estimate, WBSEDCL’s official calculator takes appliance wattage and hours per day to estimate kWh and cost. It says its estimate excludes fixed charges and meter rent, so treat it as an energy-cost estimate rather than a complete bill forecast. WBSEDCL energy-cost estimator

Measure the PC’s actual draw during playback
No scenario-specific measurement establishes how much an unspecified Windows gaming PC draws while replaying a YouTube VOD. A PSU rating or a power figure from a different workload is not a measurement of this activity. Replaying a video is not the same workload as running a demanding game, but that observation does not supply a reliable wattage for your system.
- Use a plug-in electricity usage meter that fits your socket and is rated for the connected load. Check its compatibility and rating before use.
- Connect the complete PC setup you want to count. If you also want to include a monitor or other equipment, ensure the meter and its rating cover the connected devices.
- Play the VOD under the conditions you care about and record the meter’s energy reading over a known period. An average over the whole replay is more useful for this calculation than a brief power spike.
- Use the measured average watts and replay duration in the formula, or use the meter’s recorded kWh directly. Multiply the resulting energy by your applicable marginal energy charge.
If you cannot measure the draw, you can still estimate the cost by choosing an explicit wattage assumption. Label it as an assumption, and understand that the result changes in direct proportion to that input.

Understand what the estimate leaves out
Multiplying kWh by a rate estimates the energy-charge portion, not necessarily the full bill impact. Slab-based tariffs, fixed charges, meter rent, duties, fuel adjustments, subsidies, and other local rules can change the amount shown on a bill. WBSEDCL’s estimator explicitly excludes fixed charges and meter rent; consult your utility’s current tariff and bill for the applicable details.
