How Much Does It Cost to Run a Home Server or NAS in Canada? (2026)
A network-attached storage box runs 24 hours a day, so even a modest 40 watt draw adds up to 350 kWh a year. Repurposed desktop PCs used as servers can use three times that.
A typical home server or NAS (40 W) costs C$0.006 per hour, or about C$4.03 per month at 24 hours a day in Canada. Average running cost
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low 15 W | C$0.002 | C$0.050 | C$1.51 | C$18.40 |
| Typical 40 W | C$0.006 | C$0.13 | C$4.03 | C$49.06 |
| High 150 W | C$0.021 | C$0.50 | C$15.12 | C$183.96 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 24 h/day ≈ 350 kWh per year.
One day of a home server or NAS (0.96 kWh) is the same electricity as
- 5.3km in an electric car
- 9.6hours of TV
- 21hours of a laptop
- 107hours of an LED bulb
In Canada, with electricity at 14.0¢ per kWh (source: Canada Energy Regulator 2026 market snapshot, 2026-06), a typical home server or nas costs C$0.006 per hour and about C$49.06 per year at 24 hours a day. Each C$1.00 of electricity buys roughly 178.6 hours of use.
How to lower the cost of running a home server or NAS
- Enable disk spin-down for drives that are rarely accessed.
- Choose low-power hardware. A purpose-built NAS uses a fraction of an old desktop.
- Consolidate services onto one box rather than running several.
