Electricity Consumption Calculator

Understanding your electricity consumption — which appliances use the most, and what your daily usage adds up to — is the foundation of every energy-saving plan. This Electricity Consumption Calculator estimates one of those consumption figures from your usage pattern.

The calculation totals appliance energy use in kilowatt-hours, which maps directly to the units on your electricity bill and its cost at your tariff.

Most households discover the same pattern: a handful of appliances — air conditioners, heaters, geysers, water pumps — account for the majority of the bill. Quantifying each one's share is the first step to cutting it.

Use this with the appliance-cost tool: calculate each appliance's consumption, then its cost, and rank them. The ranking shows exactly where behaviour changes deliver the largest savings.
