How Much Does It Cost to Run a Smart Speaker in India? (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 ₹0.018 per hour, or about ₹12.96 per month at 24 hours a day in India. Cheap to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (2 W) | ₹0.012 | ₹0.29 | ₹8.64 | ₹105.12 |
| Typical (3 W) | ₹0.018 | ₹0.43 | ₹12.96 | ₹157.68 |
| High (6 W) | ₹0.036 | ₹0.86 | ₹25.92 | ₹315.36 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 24 h/day ≈ 26 kWh per year.
In India, with electricity at ₹6.00 per kWh (source: Typical urban domestic slab rate; national average ≈ ₹5.5/unit FY2025-26, 2026-04), a typical smart speaker costs ₹0.018 per hour and about ₹157.68 per year at 24 hours a day. Each ₹1.00 of electricity buys roughly 55.6 hours of use.
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 (₹105.12) per year if it is never unplugged.
