How many watts does an electric blanket use?
An electric blanket uses 100–200 W (about 150 W on average). Running 8 hours/day, that is about 1.20 kWh a day and 36.0 kWh a month — roughly $6.60 a month at the U.S. average rate of 18.34 ¢/kWh.
This is the electric blanket electricity usage reference: watts, amps on a 120 V circuit, the kWh math, and links to what that usage costs in each state.
Watts, amps, and kWh for an electric blanket
| Measure | Value |
|---|---|
| Rated wattage range | 100–200 W |
| Average draw used in our math | 150 W |
| Amps at 120 V | 0.8–1.7 A (1.3 A at the average draw) |
| kWh per hour | 0.15 kWh |
| kWh per day at 8 hours/day | 1.20 kWh |
| kWh per month | 36.0 kWh |
| Cost per month at the U.S. average (18.34 ¢/kWh) | $6.60 |
The math is kWh = watts × hours ÷ 1000 and amps = watts ÷ volts. A standard 120 V household circuit on a 15 A breaker carries about 1,800 W. For the dollars in your state, open cost to run an electric blanket in Texas and switch states from there.

Frequently asked questions
How many watts does an electric blanket use?
An electric blanket uses 100–200 W (about 150 W on average). Our usage and cost math uses 150 watts running 8 hours/day.
How many amps does an electric blanket draw?
On a 120 V circuit, 100–200 W works out to about 0.8–1.7 A; at the 150 W we use in the math that is 1.3 A.
How much electricity does an electric blanket use per month?
About 36.0 kWh a month at 8 hours/day. Lighter use (4 hours/day) comes to roughly 18.0 kWh and heavier use (12 hours/day) roughly 54.0 kWh.
How much does it cost to run an electric blanket?
About $6.60 a month at the U.S. average rate of 18.34 ¢/kWh — from roughly $4.72 in Nevada to $18.98 in Hawaii at the same usage. The state cost-to-run pages price it at every state's rate.
