How Much Does It Cost to Run a Cable or Fiber Modem in Minnesota? (2026)
A modem runs all day at 5 to 15 watts. Combined with a separate router the pair uses around 15 to 25 watts continuously, roughly 150 to 200 kWh a year.
A typical cable or fiber modem (8 W) costs $0.001 per hour, or about $1.04 per month at 24 hours a day in Minnesota. Cheap to run
| Wattage | Per hour | Per day | Per month | Per year |
|---|---|---|---|---|
| Low (5 W) | $0.001 | $0.022 | $0.65 | $7.88 |
| Typical (8 W) | $0.001 | $0.035 | $1.04 | $12.61 |
| High (15 W) | $0.003 | $0.065 | $1.94 | $23.65 |
Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 24 h/day ≈ 70 kWh per year.
One day of a cable or fiber modem (0.19 kWh) is the same electricity as
- 3.8hours of a fridge
- 4.3hours of a laptop
- 19hours of Wi-Fi
- 21hours of an LED bulb
In Minnesota, with electricity at $0.18 per kWh (source: EIA Table 5.6.A, 2026-06), a typical cable or fiber modem costs $0.001 per hour and about $12.61 per year at 24 hours a day. That is about 0% less than the national average for the US ($1.04 per month), because electricity in Minnesota costs $0.18 per kWh against $0.18 nationally. Each $1.00 of electricity buys roughly 694.4 hours of use.
How to lower the cost of running a cable or fiber modem
- Replace a separate modem and router with a combined gateway to halve the draw.
- Do not turn it off at night. Reconnection delays are rarely worth the small saving.
- Retire old network gear. Older units often use double the power of current ones.
