Gaming PC Electricity Cost Calculator

What a gaming PC adds to the bill, from the power it draws while you are actually playing.

Your figures

The figure that matters is what the machine draws under load, not at idle. A plug-in energy meter read during a game is the honest way to get it.

Use fewer for something you only run at weekends.

Rupees per unit (kWh), from your own bill. Tariffs differ by state, by connection and by how much you use, so this is the figure the result is most sensitive to.

About this calculator

A gaming machine under load can draw five times what it draws at idle. That is why costing one on a general "PC wattage" figure is meaningless, and why this page asks for the number you measured while playing.

How to use this calculator

  1. Put a plug-in energy meter between the wall and the machine and read it while a demanding game is running.
  2. Enter that figure, the hours you play a day and the days a month.
  3. Enter your electricity rate from your own bill.

Include the monitor in the measurement if it is on the same meter, and say so to yourself when comparing with a machine-only figure.

The formula

Energy a day  = Power / 1000 x Hours a day
Cost a month  = Energy a day x Days a month x Rate per unit
SymbolMeaningUnit
Power Draw while gaming W
Hours Gaming hours a day h
Rate Your tariff per unit ₹/kWh

Worked example

A machine drawing 450 W while playing, three hours a day, 30 days, at ₹8 a unit:

Energy a day = 450 / 1000 x 3 = 1.35 kWh
Cost a month = 1.35 x 30 x 8   = 324

Just under ₹3,900 a year of gaming.

Notes and limits

  • This costs the hours you play. The machine's idle and browsing hours are a separate figure, and the PC electricity cost calculator will take them.
  • Frame rate limits and a monitor's refresh ceiling both cut power noticeably: a card rendering 300 frames a second on a 60 Hz display is burning electricity for nothing.
  • A gaming machine is also a heater. In an Indian summer with air conditioning, some of the cost appears on the cooling side of the bill as well.
  • The power supply's rating is not the machine's draw and will overstate this several times over.

What this calculation assumes

  • The power figure is one you entered and is assumed to hold for the whole session.
  • Only gaming hours are counted. Idle and other use are not in this figure.
  • This is energy cost at the rate you entered, not a bill.

Frequently asked questions

How much does gaming cost in electricity?

Multiply what the machine draws while playing by the hours and your tariff. A 450 W machine for three hours a day at ₹8 a unit is about ₹324 a month. The wattage is the figure that decides it, and it has to be measured rather than assumed.

How do I measure my gaming PC's power draw?

A plug-in energy meter between the wall and the machine, read while a demanding game is running. Software estimates for the processor and graphics card are useful but miss the rest of the system and the supply's own losses.

Does capping the frame rate save electricity?

Measurably, yes. A graphics card rendering far more frames than the display can show draws close to its maximum for no visible benefit. Capping to the refresh rate often drops the card's power substantially.
