Typical electricity cost

How much does a Mini Fridge cost to run?

Based on typical usage

A Mini Fridge typically draws about 90 watts when its cooling cycle is active, averaging around $0.00 per hour at $0.15 per kWh.

At typical use (35% active runtime over 24 hours), that's about $3.40 per month and $41.39 per year.

Hourly average $0.00
Daily $0.11
Monthly $3.40
Yearly $41.39

Based on

  • 90 watts
  • 35% active runtime over 24 hours
  • Typical temperature setting
  • $0.15 per kWh

What affects cost most

  • Average active runtime over a full 24-hour day
  • Electricity rate in dollars per kWh
  • Temperature setting, door openings, and room temperature

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 50% active runtime over 24 hours and Colder setting
    $5.44/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
  • Temperature setting, door openings, and room temperature

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.
  • Match the temperature setting to your real target, especially for heating and cooling equipment.
  • Keep the coils and vents clear for airflow.
  • Avoid placing the unit in hot garages or direct sun.
  • Set the temperature only as cold as needed.
