Electric Blanket Cost Per Night Used: Include Heat Settings and Actual Bedtime
Quick answer: Estimate an electric blanket or heated throw cost per night from measured watts at each heat setting, thermostat cycling, preheating time, electricity rates, and nights used instead of its maximum label.
Inputs that change the result
Measure wall watts during preheat and low, medium, and high settings. Record thermostat cycling, hours before sleep, hours actually used, dual controls, automatic shutoff, rate, and whether one or two sides are heated.
Formula and worked example
nightly blanket electricity cost = (preheat kWh + low/medium/high setting kWh) × delivered electricity rate. For dual-control bedding, measure each side and divide only shared costs when comparing one-person and two-person use. A blanket averages 80 W for 1 preheat hour and cycles at 35 W for 7 sleeping hours, using 0.325 kWh. At 0.20/kWh, direct energy is about 0.07 per night. A higher setting, a second control, or a longer preheat changes the result.
Compare real use cases
Compare warming the bed for an hour then switching low, running medium all night, and heating one side of a dual-control blanket. EIA supplies the unit and price framework; the thermostat pattern must come from your measured blanket and routine.

Limits and common mistakes
Fabric, room temperature, body heat, bedding layers, thermostat cycling, control electronics, auto-off, voltage, and preheating change wall energy. Follow the manufacturer safety instructions and do not infer safe use or health effects from a cost estimate.
Frequently asked questions
Is an electric blanket cheaper than heating the whole room?
It may use less measured electricity for a personal heat target, but the comparison is not universal. Measure the blanket and room-heating equipment, define the same comfort period, and keep safety and comfort constraints visible.
