Washing-machine electricity cost calculator
Estimate washing-machine electricity cost per month and year from cycle duration, power, load frequency, and your tariff.
Transparent method
The calculation
Monthly cost = average active kW × cycle hours × weekly cycles × 52 ÷ 12 × tariffA washing cycle contains heating, motor, pump, and idle stages. Use a meter or the programme's stated kWh per cycle when available; otherwise model average active power conservatively.

Run three scenarios.
01
Cold washUse lower average active power when water heating is avoided.
02
Eco programmeLonger duration can still use less energy.
03
Hot intensive cycleTest higher active power and a longer heating stage.
Use the result well
What can change the answer?
- Rated heater power is not the cycle's average power.
- Water heating usually dominates electricity use.
- Drying, if built in, should be modelled separately.
