How Much Does It Cost to Run a Heated Pet Bed?
A heated pet bed sips about 40 watts, and most only warm up under the animal's weight. At the US-average rate of 16.5¢/kWh, running a heated pet bed costs about $2.41/month ($28.87/year) at typical use. Adjust the watts, hours, and your rate below for your exact number.

Cost = power (kW) × hours × days × your rate. Defaults are typical values — enter your appliance's actual watts (often on a label) and your real rate for a precise figure.
How much electricity does a heated pet bed use?
At 40 W for 12 hours a day, a heated pet bed uses about 0.5 kWh per day — roughly 15 kWh per month and 175 kWh per year. That's about 2% of the 863 kWh the average US home uses in a month. Energy use is the same everywhere — only the price per kWh changes your bill.

Measure what a heated pet bed really costs you
The estimate above uses typical wattage and hours. A plug-in energy meter logs the kilowatt-hours this appliance actually uses — leave it in for a week, multiply by your rate, and the estimate becomes a measurement. A whole-home monitor does the same for every circuit at once, but its sensors install inside the panel.
