How much does it cost to run an electric blanket?

The cost to run an electric blanket depends on the cost of electricity per kilowatt-hour, the heat setting used on the blanket and the amount of time the blanket is used. Given all these factors, an electric blanket costs anywhere from 4 to 30 cents per night, as of 2014.

While most electric blankets can use up to 200 watts on high, most people only use 40 to 50 watts of energy because they don't turn their blankets all the way up. Electric mattress pads use slightly less energy than electric blankets and cost as little to run as 2 or 3 cents per night, as of 2014.
