About network switch running costs
A network switch often runs continuously, making its low wattage worth multiplying by all 24 hours. PoE models can draw much more when powering devices.
Typical sizes: 10 W, 20 W, 40 W, 100 W.
How to spend less: Check the switch’s actual power draw, especially if it supplies power over Ethernet.
What this estimate assumes
- The appliance draws its full stated wattage the whole time it is on. Real units with a thermostat cycle off and cost less.
- Wattage is the typical label value, not a measured value. Check the label on your own appliance.
- The rate is an approximate residential average in Illinois. Your bill may include fixed fees, tiers or time-of-use pricing. Edit the rate above.
- A month is 30 days and a year is 365 days.
