How much does it cost to run a electric space blanket?
A typical electric space blanket draws about 75 watts. Used 6 hours a day, that works out to roughly $0.08 per day, $1.15 per month, and $13.77 per year on an average electricity rate of 17¢ per kWh. Personal heating blankets use modest power but add up with extended nightly use during winter months.

Based on 81 kWh per year. Adjust the price per kWh to match your latest electricity bill for an exact figure.
The number that matters most is your own electricity rate. Rates range from under 11¢ per kWh in some regions to over 30¢ in others, so the same electric space blanket can cost two or three times as much depending on where you live. Enter your exact rate in the calculator above to get a figure tailored to your bill.
Heating appliances like the electric space blanket are usually seasonal, so your real annual cost depends heavily on your climate and how many months you run it. The figures here assume average year-round use — if you only switch it on during the coldest part of the year, scale the monthly cost by the number of months you actually use it.
At 75 watts, the electric space blanket is a low-power device, so its cost per hour is small. The annual total only becomes meaningful if it runs for many hours a day — which is exactly why long-running low-wattage devices are easy to overlook on a bill.
Over a full year this electric space blanket uses about 81 kWh of electricity and is responsible for roughly 32.4 kg of CO₂ emissions on an average grid. Since it is used only part of the year, your real footprint scales with the season — the annual figure assumes a typical usage pattern.
To put the draw in everyday terms, one hour of running this electric space blanket uses about as much electricity as charging a smartphone 6 times. It is a rough comparison, but it makes an abstract wattage figure easier to picture.
If this electric space blanket is one you use daily, even small efficiency gains compound. Cutting its usage or wattage by 20% would save around $2.75 every year — money that an efficient replacement can recover over its lifetime.
