How to use this tool

  1. Enter appliance power, operating hours, price per kwh.
  2. Select Calculate to view the result.
  3. Check the method and assumptions below before using the result.

The method, explained

Cost = watts/1000 × hours × price per kWh.

A WORKED EXAMPLE

Using appliance power = 1000 W, operating hours = 3 hours, price per kwh = 0.2 money/kWh, the result is 0.6 currency. Change these example inputs to match your task; use the method above to check each step.

What to keep in mind
