Direct heat keeps wattage low
An electric blanket warms a person or bed directly instead of heating an entire room. That is why its wattage is usually much lower than a space heater.

$0.14 per day
This uses 100 watts, 8 hours per day, and an electricity rate of $0.17 per kWh.
Electric blankets use low wattage compared with room heaters because they warm a small area directly.
Typical electric blanket wattage
Many electric blanket units fall around 100 watts, with a rough range of 60 to 200 watts. Check the product label, user manual, or manufacturer specifications for the most accurate number.
| Estimate | Watts | Hours per day | Daily cost | Monthly cost |
|---|---|---|---|---|
| Low estimate | 60W | 4 | $0.04 | $1.22 |
| Typical use | 100W | 8 | $0.14 | $4.08 |
| High estimate | 200W | 12 | $0.41 | $12.24 |
How the estimate works
Convert watts to kilowatts, multiply by the number of hours used, then multiply by your electricity rate.
Cost = Watts / 1000 x Hours Used x Electricity RateFor this electric blanket example: 100 / 1000 x 8 x 0.17 = $0.14 per day.
Electric Blanket cost factors
These details make this estimate more useful for real-world use.
Settings and runtime still matter
Higher heat settings use more power, and overnight use adds hours. Preheating the bed and lowering the setting after you are comfortable can keep the total cost small.
How to lower the cost
Preheat the bed, then lower the setting for overnight comfort.
The easiest way to improve the estimate is to replace the default values with your actual wattage, average runtime, and local electricity rate.
