Calculate your cost
Start with the example below, then replace the wattage, daily runtime, and rate with the numbers for your soundbar.
This setup uses about 4 kWh in a 30-day month.
Please enter valid values within the ranges shown.
| Schedule | Hours/day | Cost/month |
|---|---|---|
| Half runtime | 2 | $0.40 |
| Page example | 4 | $0.79 |
| Longer runtime | 6 | $1.19 |
Same 35-watt input and 18.83¢/kWh rate; only runtime changes.
Formula for the page example
0.04 kW × 4 hr × $0.1883 = $0.03 per day
Convert watts to kilowatts, multiply by the active hours used each day, then multiply by the electricity price in dollars per kWh. Multiply the daily result by 30 for the monthly estimate shown above.
How to read this estimate
Audio equipment generally uses minimal electricity compared to the screens they accompany.
Use this as a baseline until you can check the label or measure the soundbar directly. Model, settings, condition, climate, and household routine can all change the result.
