How many watts does a Wi-Fi Router / Modem use?

A Wi-Fi Router / Modem draws a steady 20 watts with no meaningful startup surge, since it has no motor to spin up.

Running it 24 hours/day costs roughly $2.45/month at the U.S. average residential rate (~$0.17/kWh, early 2026, per the EIA) — real rates vary a lot by state and utility. Use your own rate in the House calculator →
