Vacuum Cleaner Energy Cost Calculator

Work out vacuum cleaner energy cost instantly with clear inputs, formula shown and shareable results.

About Vacuum Cleaner Energy Cost Calculator

Vacuum cleaners run for short periods, so annual cost is small: 750 W for fifty minutes a week is about 32 kWh and nine pounds a year. EU regulation capped motor input at 900 W in 2017, and cleaning performance did not suffer because airflow design matters more than raw power.

Formula

Vacuum cost

annual kWh = rating (kW) x minutes per week / 60 x weeks; cost = kWh x tariff

Worked example

With the default values below, Vacuum Cleaner Energy Cost Calculator returns Annual running cost of $9.10. Change any input above and every figure here is recalculated in your browser.

Assumptions and limits

The result is derived only from the 4 inputs listed above. Anything not among them is not part of the calculation.
In particular, this calculator does not take inflation, tax or fees or charges into account.
Figures are rounded for display to 4 decimal places, so totals built from several rounded parts can differ slightly from the unrounded arithmetic.

How these calculators are built and tested is described on the Methodology page. If a figure looks wrong, please report it.

Frequently Asked Questions

Did the wattage cap reduce cleaning performance?

No. Suction at the head depends on airflow and sealing, not motor input. Well-designed 700 W machines outperform old 2,000 W ones.

Are cordless vacuums cheaper to run?

Slightly, because they draw less power, but battery replacement every few years usually outweighs the electricity saved.
