ELECTRICITY CALCULATOR
Wi-Fi router power cost comparison
Compare the electricity cost of two wi-fi router options using average input power and your own tariff.
How this calculation works
Average input watts ÷ 1,000 × hours per day × days gives kWh for each option. Multiply each by the price per kWh and subtract B from A. A negative difference means B costs more. Use measured average wall power: duty cycles and operating conditions vary. Fixed charges, taxes and tariff changes are excluded.
