How Much Does It Cost to Run a Smart Speaker in Oklahoma? (2026)
Smart speakers listen constantly and draw 2 to 4 watts idle, rising slightly when playing music. Each one adds around 20 to 30 kWh a year, which matters mainly if you have many.
A typical smart speaker (3 W) costs $0.000 per hour, or about $0.31 per month at 24 hours a day in Oklahoma. Cheap to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low 2 W | $0.000 | $0.007 | $0.21 | $2.51 |
| Typical 3 W | $0.000 | $0.010 | $0.31 | $3.77 |
| High 6 W | $0.001 | $0.021 | $0.62 | $7.53 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 24 h/day ≈ 26 kWh per year.

- 4.8phone charges
- 7.2hours of Wi-Fi
- 8.0hours of an LED bulb
In Oklahoma, with electricity at 14.3¢ per kWh (source: EIA Table 5.6.A, 2026-06), a typical smart speaker costs $0.000 per hour and about $3.77 per year at 24 hours a day. That is about 22% less than the national average for the US ($0.40 per month), because electricity in Oklahoma costs 14.3¢ per kWh against 18.3¢ nationally.

How to lower the cost of running a smart speaker
- Count them. Six speakers at 3 watts each cost more than a fridge over a year.
- Turn off the always-on display on models that have one.
- Unplug speakers in rooms you rarely use.
In standby it draws about 2 W, which adds roughly 18 kWh ($2.51) per year if it is never unplugged.
