Electricity use guide
Estimate kWh and variable cost with your tariff.
Measure and prepare
- Check the units shown for each input. Measure the actual inside dimensions or net area required by this tool.
- Use manufacturer coverage, dose, pack size or your measured flow where applicable. Do not treat example inputs as product recommendations.
- Check the assumptions below, update the starting values and review whole-unit purchase rounding where applicable.
Method and limits
Electrical input watts ÷ 1000 × daily hours × days × effective operating percentage. Multiply kWh by your entered price. Thermal air-conditioning capacity is not electrical input. Fixed charges are excluded.
Worked example
With the editable starting values: 60 kWh in the period. 12 € variable cost · 2 kWh per day · 0.2 €/kWh. Excludes fixed charges.
- Electrical input power (W): 1000
- Daily hours of use: 2
- Days in period: 30
- Effective time at that power (%): 100
- Final variable price (€/kWh): 0.2
