Estimate laundry running costs from electricity and water used per wash and your own tariffs. Optional dryer electricity is included for each planned load. The calculator shows per-load, weekly and 52-week totals in your selected currency, excluding fixed fees, detergent, maintenance and appliance purchase costs.
Use consumption and prices from the same scenario
Enter measured consumption or identify the exact programme’s published figures and conditions. Energy labels describe specific test conditions rather than every programme. The starting values are editable examples. Keep electricity and water prices in the selected currency; changing the currency label does not exchange the entered amounts.
Use litres with a tariff per 1,000 litres, or US gallons with the corresponding gallon tariff. Re-enter values after changing water units. If you enter combined wash-and-dry energy, do not add the dryer use a second time. Gas drying and externally heated water require costs outside the electricity-only dryer entry.

The cost-per-wash formula
Electricity cost is kWh multiplied by price per kWh. Water cost is water used divided by 1,000, multiplied by its tariff per 1,000 units. Add the optional dryer electricity cost.
An illustrative wash using 0.8 kWh at 0.30 and 50 litres at 2.00 per 1,000 litres costs 0.24 + 0.10 = 0.34. Five such washes per week cost 1.70 weekly and 88.40 over 52 weeks. These example figures are not appliance measurements or current utility prices.
Common questions
Does the annual result predict my full utility bill?
No. It estimates the entered metered laundry consumption over 52 weeks. Fixed charges and other household use are excluded.
What if I dry only some loads?
The entered dryer consumption is applied to every planned wash. Compare separate scenarios for machine-dried and other loads.
Where should I get tariff values?
Use your own billing information and applicable variable charges. The site does not supply live regional tariffs.
