A Wi-Fi 6 router like the AVM FRITZ!Box 4050 averages 5 to 7 W, according to the maker. This page uses the middle of that range, 6 W. Running all year, that's 52.6 kWh, which costs $9.46 at $0.18/kWh, or $0.79 a month.

The table below prices 6 W at three dollar rates and three euro rates.

How this is calculated

AVM's FRITZ!Box 4050 specifications list an average power consumption of 5 to 7 W for this Wi-Fi 6 (802.11ax) router. At the low end that's $7.88 a year at $0.18/kWh, and at the high end it's $11.04. AVM doesn't say how it measured the average, so this page takes the middle of the range.

A router is a device that never sleeps, so the hours are 24 and the average goes in at 100% utilization. A modem, a fiber ONT, mesh nodes and switches are separate devices with their own draw, and each needs its own measurement. Other router models differ, so use the maker's figure for yours if it lists one.

Verdict

A router costs about $9 a year to leave on at $0.18/kWh, and about €16 at €0.30/kWh. Most homes keep it on, because every other device loses its connection when it's off.

Switching it off for 8 hours every night would save about $3.15 a year at $0.18/kWh. Backups, cameras and smart home devices that work overnight would stop with it.
