Processing method
Calculator results are estimates produced from the wattage, time, rate, or quantity values you enter. Tariffs, tiered billing, automatic device controls, and real-world conditions can differ, so compare the result with official bills or product labels.
Gaming and light-work wattage and hours are estimated separately, then monitor usage is added for the monthly total.

Frequently Asked Questions
Is PC power use the same as PSU wattage?
No. PSU wattage is capacity. Actual use depends on CPU and GPU load, components, and power-supply efficiency.
Why separate gaming and light-use hours?
CPU and GPU load is much higher while gaming than during browsing or documents, so splitting time gives a better estimate.
How can I measure actual PC power?
Use a plug-in power meter while gaming and during light work, then enter the measured wattage.
