How we worked it out

  1. Energy per hour: 100 W ÷ 1,000 = 0.1 kWh, × 50% of the time at full power = 0.05 kWh
  2. Cost per hour: 0.05 kWh × $0.18 = $0.009
  3. Cost per day: × 6 hours = $0.054
  4. Month and year: × 30 days = $1.62, × 365 days = $19.71

About heated mattress pad running costs

Heated mattress pads warm a bed directly, so their energy use is usually much lower than heating the whole bedroom. Thermostats cycle the element.

Typical sizes: 60 W, 100 W, 120 W, 180 W.

How to spend less: Pre-warm the bed and use a low setting with the built-in timer.
