How much does it cost to run a soundbar?
We've pre-filled a typical soundbar below. Set your electricity rate and adjust the hours to match how you use yours — the cost updates instantly.
A soundbar is one of the cheapest things in your entertainment setup to run — and it's not close. Most soundbars pull somewhere between 15 and 80 watts while actively playing, with the number climbing as you push the volume and the built-in amp works harder to drive the speakers. Even at the high end of that range, a soundbar draws less power than a single bright light bulb, so the electricity it uses while you're actually watching or listening is close to a rounding error on your bill.
Where a soundbar quietly adds up is standby. Most models sit plugged in around the clock listening for a signal from your TV or remote, drawing a trickle of power 24/7 even when nothing's playing — and unlike a lamp you switch off, nobody unplugs a soundbar between movies. If you want to know where your money actually goes, it's less about turning the volume down and more about whether the thing you rarely use is still drawing power on a shelf all day and night.
What drives the cost of running a soundbar
- Volume and content: louder playback and bass-heavy audio push the amplifier harder, moving draw toward the top of the 15-80W range
- Model and size: a compact 2.0 soundbar sits near 15-30W, while a bar with a wireless subwoofer or multiple satellite speakers draws more
- Standby time: most soundbars stay powered on and listening for a signal even when silent, adding small but constant background cost the wattage-while-playing number doesn't capture
How to cut it
- Skip the max-volume habit for background listening — loud passages and bass-heavy content make the amplifier work harder and draw more power than quiet dialogue or moderate levels
- Turn it off (not just muted) when you leave the room for a while, since muting typically doesn't drop power draw to standby levels
- Use a smart plug or the TV's ARC/CEC auto-power feature so the soundbar doesn't sit in standby for hours after you've stopped watching
- If you rarely use it, unplug it between sessions — standby draw on some models runs 24/7 for basically no benefit
Common questions
How much does it cost to run a soundbar per month?
At a typical 30W and about 4 hours a day, a soundbar costs roughly $0.61 a month at $0.17/kWh. Set your own rate and hours above for an exact figure.

Does a soundbar use much power in standby mode?
Some. Most soundbars stay in standby whenever they're plugged in, ready to wake on a signal from your TV or remote, and that trickle draw runs 24/7 — not just during the hours you're listening. It's usually just 1-6 watts, but because it never turns off, it can add up to more of the soundbar's yearly cost than the actual watching time does.
Does a soundbar with a wireless subwoofer cost more to run than a single bar?
Yes, a bit. The subwoofer has its own amplifier and power draw, plus its own standby draw when idle, so a bar-plus-sub system typically lands toward the higher end of the wattage range rather than the low end — closer to a small AV receiver than a simple 2.0 bar.
