Electric blanket usage typically costs about $2-$10 per month, depending on wattage, hours used, and the local electricity rate. A standard 100-watt blanket used eight hours nightly at 16 cents per kilowatt-hour costs roughly $3.84 per month; larger or higher-powered models can cost more.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Electricity per hour | $0.004 | $0.016 | $0.040 | Based on 25, 100, or 250 watts at $0.16/kWh |
| Monthly use | $0.50 | $3.84 | $19.20 | Eight hours nightly for 30 days |
| Annual use | $6 | $46 | $230 | Same daily schedule for 12 months |
What an electric blanket costs to run each month
Most electric blankets draw about 50-200 watts once warmed, though some larger or dual-control models can use more. At a national planning rate of 16 cents per kWh, that works out to about $0.008-$0.032 per hour, or $1.92-$7.68 monthly when used eight hours a night for 30 days. A 250-watt setting would cost about $12 monthly on that schedule.
For a typical 100-watt blanket, budget about $4 monthly for nightly eight-hour use. This estimate assumes the blanket averages its stated wattage throughout the session; thermostats often cycle on and off, so actual consumption may be lower. Assumptions: 30 nights, eight hours per night, electricity at $0.16/kWh.
How blanket wattage and electricity rates shape the bill
Electricity use is calculated by multiplying kilowatts by hours, then by the utility rate. For example, 100 watts equals 0.1 kilowatt; used for eight hours, it consumes 0.8 kWh and costs $0.13 at 16 cents per kWh. The daily figure multiplied by the number of nights gives a practical monthly estimate.
Every additional 100 watts used for eight hours adds about 13 cents per night at $0.16/kWh. Check the blanket’s label for wattage and the electric bill for the actual energy charge. Some bills include separate delivery charges, so the all-in rate can exceed the advertised supply rate.
Which parts of the electric blanket quote add to cost
For electricity use, the main expense is energy rather than labor or installation. Purchase price is separate from running cost, but a blanket’s size, controls, and heating zones affect both its upfront price and potential draw. The table estimates operating expense only and uses a consistent $0.16/kWh rate.
| Usage case | Energy used | Daily electricity | Monthly electricity | Annual electricity |
|---|---|---|---|---|
| 50 watts, 8 hours nightly | 0.4 kWh/night | $0.06 | $1.92 | $23.36 |
| 100 watts, 8 hours nightly | 0.8 kWh/night | $0.13 | $3.84 | $46.72 |
| 200 watts, 8 hours nightly | 1.6 kWh/night | $0.26 | $7.68 | $93.44 |
At the same rate and schedule, doubling wattage doubles the estimated electricity expense. These figures do not include the blanket’s purchase price, which commonly ranges from about $30-$150 depending on size and controls.
What changes the price for a 50- to 200-watt blanket
Wattage is the largest equipment-specific variable. A small throw may use around 50-100 watts, while a full or queen blanket can draw roughly 100-200 watts; dual-control bedding may have separate zones with a combined rating above 200 watts. Use the total rated draw when estimating a two-sided model.
Hours matter just as much: four hours nightly costs half as much as eight hours at the same setting. Thermostats cycle rather than continuously heating, and preheating on high before switching to low can reduce average draw. Using a blanket for four hours instead of eight cuts its energy estimate by 50%. Local rates also shift the result: at $0.10/kWh a 100-watt blanket used eight hours costs $2.40 monthly; at $0.30/kWh it costs $7.20.
How an electric blanket compares with heating a bedroom
A blanket warms the bed’s immediate area, while a space heater or central system heats more air and surfaces. A 1,500-watt space heater running eight hours daily at $0.16/kWh costs about $1.92 per day, or $57.60 for 30 days, before thermostat cycling. A 100-watt blanket on the same schedule costs about $0.13 daily.
Targeted bed warming can use far less electricity than heating a room overnight. Actual savings depend on whether the household can lower its thermostat safely and comfortably, as well as the home’s insulation and heating system. A blanket is not a substitute for maintaining safe indoor temperatures for people, pets, or plumbing.
What three common nightly schedules cost
These examples use a 100-watt blanket and a $0.16/kWh rate. They illustrate how hours of operation, not just the appliance rating, determine the bill.
| Schedule | Use per night | Monthly estimate | Annual estimate |
|---|---|---|---|
| Preheat only | 1 hour | $0.48 | $5.84 |
| Part of the night | 4 hours | $1.92 | $23.36 |
| Full night | 8 hours | $3.84 | $46.72 |
A one-hour preheat schedule costs about one-eighth as much as continuous eight-hour use. If the blanket has an automatic shutoff, the timer can help keep the selected schedule consistent.
How to lower electric blanket running costs
Choose the lowest comfortable heat setting and use a timer or automatic shutoff rather than leaving the blanket on all night. Preheating the bed for 30-60 minutes can provide warmth at a fraction of the cost of a full-night schedule. For dual controls, turn off the unused side when one person does not need heat.
Compare the wattage label before buying similarly sized models, but do not assume the lowest rating alone guarantees the lowest bill if it must run longer to feel comfortable. Follow manufacturer instructions for safe use, inspect cords and controls, and avoid folding or covering the blanket in ways the manual prohibits. Reducing operating time is usually the simplest direct way to reduce the electricity charge.
