Work it out for your home

Units a month

Units = watts ÷ 1,000 × hours × 30 days. Typical rating. BEE does not publish a usage figure for this appliance, so check the watts on its rating plate and change them in the calculator.

What it adds to your bill, state by state

For Desktop with monitor (150 W), 8 hours a day (36 units a month), on each state’s current tariff with the government schemes that apply to every home. Per month; two-monthly and quarterly bills are shown as a monthly average. Duty and fuel surcharge are not included.

Why the cost differs so much

Your electricity is charged in slabs. An appliance adds its units at the top of what you already use, where each unit costs the most, and in some states it can push the whole bill into a dearer table or past the limit of a free-units scheme. That is why the same appliance costs very different amounts in different states, and in different homes in the same state.
