Enter your electric rate, then add the things you run. Costs update as you type — per day, week, month, and year.

The Hour column is what a device costs while it's actually running (watts × qty × rate); hourly totals assume everything running at once. The tier picker chooses between small, typical, and large models of a device — for the real number, check the label or nameplate on yours. For always-on things like a fridge, the compressor cycles — presets here use average draw, not peak. A month is counted as 30.44 days.
