How many watts does a Box Fan use?

A Box Fan draws a steady 100 watts with no meaningful startup surge, since it has no motor to spin up.

Running it 8 hours/day costs roughly $4.08/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 →
