How to estimate dishwasher correctly
The 1800 W and 1.5 h/day values are an editable example, not a claim about every model. This appliance is best treated as per-cycle use.
What to verify
Eco programmes often run longer but heat less water. Compare kWh per cycle from the label, not programme duration alone.
Formula
Power (W) ÷ 1,000 × active hours × electricity rate. This example uses 2.7 kWh/day, 81 kWh/30 days and 985.5 kWh/year.
Accuracy limit
The calculator prices the values you enter. It cannot know thermostat cycles, power modes, losses, appliance condition or the exact tariff on your bill; verify those inputs for a decision.
