How we worked it out

  1. Energy per hour: 50 W ÷ 1,000 = 0.05 kWh
  2. Cost per hour: 0.05 kWh × $0.175 = $0.009
  3. Cost per day: × 4 hours = $0.035
  4. Month and year: × 30 days = $1.05, × 365 days = $12.78

About soundbar running costs

Soundbar power depends on volume, wireless features and standby mode. Peak audio output is not the same as average power consumption.

Typical sizes: 25 W, 50 W, 100 W, 150 W.

How to spend less: Disable always-on features you do not use and check standby settings.

What this estimate assumes

  • The appliance draws its full stated wattage the whole time it is on. Real units with a thermostat cycle off and cost less.
  • Wattage is the typical label value, not a measured value. Check the label on your own appliance.
  • The rate is an approximate residential average. Your bill may include fixed fees, tiers or time-of-use pricing. Edit the rate above.
  • A month is 30 days and a year is 365 days.
