How to estimate microwave correctly
The 1200 W and 0.25 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
Input power can be higher than the advertised cooking output. Use the rating plate on the back for electricity cost.
Formula
Power (W) ÷ 1,000 × active hours × electricity rate. This example uses 0.3 kWh/day, 9 kWh/30 days and 109.5 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.
