About this calculator

One session, one answer. A four-hour evening, an overnight render, a weekend tournament — this costs a specific stretch of time rather than a monthly habit.

Enter the power and the duration for the energy. Add your electricity rate and it puts a price on it too.

How to use this calculator

  1. Measure the machine's draw during the kind of session you are costing.
  2. Enter how long it runs, in hours or minutes.
  3. Add your rate for the cost, or leave it blank for the energy alone.

The formula

Energy = Power x Time / 1000     (kilowatt-hours)
Cost   = Energy x Rate per unit

One "unit" on an Indian bill is one kilowatt-hour.

Worked example

A 450 W machine for four hours at ₹8 a unit:

Energy = 450 x 4 / 1000 = 1.8 kWh
Cost   = 1.8 x 8         = 14.40

Fourteen rupees an evening — which is about ₹5,250 a year if it is every evening.

Notes and limits

  • Power varies through a session. A menu screen, a loading bar and a demanding scene are not the same draw, so a single figure is an average at best.
  • The monitor, speakers and anything else on the desk are separate unless they were on the same meter.
  • For a regular habit rather than one session, the gaming PC electricity cost calculator works in hours a day.
  • The heat a machine makes is real: in a small room with air conditioning, part of the cost appears on the cooling side.

What this calculation assumes

  • The power figure is assumed to hold for the whole session, which is an average at best.
  • Only the machine you measured is counted.

Frequently asked questions

How much electricity does one gaming session use?

Multiply the power draw by the hours and divide by 1,000 for kilowatt-hours. A 450 W machine for four hours uses 1.8 kWh, which at ₹8 a unit is ₹14.40.

Do I have to enter an electricity rate?

No. Leave it blank and the page gives the energy in watt-hours and units. The rate only turns that into money.

Is this the same as my bill?

It is the energy cost at the rate you entered. An Indian bill also carries a fixed charge, slab rates and duties, so the marginal cost of an extra unit may differ from your average rate.
