How Much Does It Cost to Run a Mini Fridge in Canada? (2026)

Mini fridges are surprisingly inefficient for their size. Many use half as much electricity as a full-size fridge while holding a tenth of the food, because small compressors and thin insulation work hard in warm rooms.

A typical mini fridge (80 W) costs C$0.011 per hour, or about C$2.69 per month at 8 hours a day in Canada (average). Average running cost

WattagePer hourPer dayPer monthPer year
Low (50 W)C$0.007C$0.056C$1.68C$20.44
Typical (80 W)C$0.011C$0.090C$2.69C$32.70
High (120 W)C$0.017C$0.13C$4.03C$49.06

Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 8 h/day ≈ 234 kWh per year.

In Canada, with electricity at C$0.14 per kWh (source: Canada Energy Regulator 2026 market snapshot, 2026-06), a typical mini fridge costs C$0.011 per hour and about C$32.70 per year at 8 hours a day. Each C$1.00 of electricity buys roughly 89.3 hours of use.
