How Much Does It Cost to Run a Towel Warmer?
A towel warmer is a gentle 100-watt radiator — the luxury costs a couple dollars a month if you run it a few hours a day. At the US-average rate of 16.5¢/kWh, running a towel warmer costs about $2.01/month ($24.06/year) at typical use. Adjust the watts, hours, and your rate below for your exact number.

Cost = power (kW) × hours × days × your rate. Defaults are typical values — enter your appliance's actual watts (often on a label) and your real rate for a precise figure.
How much electricity does a towel warmer use?
At 100 W for 4 hours a day, a towel warmer uses about 0.4 kWh per day — roughly 12 kWh per month and 146 kWh per year. That's about 1% of the 863 kWh the average US home uses in a month. Energy use is the same everywhere — only the price per kWh changes your bill.

Measure what a towel warmer really costs you
The estimate above uses typical wattage and hours. This load is usually hardwired or on a 240 V circuit, so a plug-in meter won't fit it; a whole-home monitor's sensors clip onto the circuit's wires inside the panel and log its real kilowatt-hours. That means working in a live panel — hire an electrician if that isn't you.
