Gaming cost examples
| Scenario | Average load | Daily play | Monthly cost | Yearly cost |
|---|---|---|---|---|
| Casual gaming | 320 W | 2 h | $3.46 | $42.05 |
| Evening gaming | 450 W | 4 h | $9.72 | $118.26 |
| Heavy gaming | 575 W | 8 h | $24.84 | $302.22 |
Method and assumptions
Gaming PC electricity cost uses the same core formula as the GPU and PC calculators: average watts divided by 1000, multiplied by hours played and electricity price per kWh. For a full desktop, adjust the wattage upward to include CPU, motherboard, storage, cooling, display, and USB device draw.
