How much does a Cable Box cost to run?

Based on typical usage

A Cable Box typically draws about 30 watts when active, averaging around $0.00 per hour at $0.15 per kWh.

At typical use (65% active runtime over 24 hours), that's about $2.11 per month and $25.62 per year.

Hourly average $0.00
Daily $0.07
Monthly $2.11
Yearly $25.62

Based on

  • 30 watts
  • 65% active runtime over 24 hours
  • $0.15 per kWh

What affects cost most

  • Average active runtime over a full 24-hour day
  • Electricity rate in dollars per kWh
  • Standby behavior, connected peripherals, and firmware settings

How it works: Daily cost uses wattage, average active runtime over 24 hours, and electricity rate. Monthly uses daily × 30; yearly uses daily × 365.

Use the calculator below to estimate cost based on your own wattage, usage time, and electricity rate.

  • Heavy Use 85% active runtime over 24 hours
    $2.75/month

Get a better estimate and keep costs down

Defaults give you a starting point, but always-on equipment can look very different once you adjust active runtime and the real power draw in your setup.

What changes cost most

  • Average active runtime over a full 24-hour day
  • Electricity rate in dollars per kWh
  • Standby behavior, connected peripherals, and firmware settings

How to get a better estimate and lower cost

  • Replace the default electricity rate with the actual rate from your latest power bill.
  • Adjust the active runtime percentage to match how often the device is actually heating, cooling, or cycling.
  • Enable deep sleep settings if your provider supports them.
  • Disable always-on recording features you do not use.
  • Turn off secondary boxes in rarely used rooms.
  • Use one primary viewing device where practical.
