How to estimate wi-fi router correctly
The 12 W and 24 h/day values are an editable example, not a claim about every model. This appliance is best treated as continuous or recurring use.
What to verify
Routers run continuously, so even a small wattage repeats 8,760 hours a year. Include a modem or mesh node separately.
Formula
Power (W) ÷ 1,000 × active hours × electricity rate. This example uses 0.288 kWh/day, 8.6 kWh/30 days and 105.1 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.
