How Much Unit of Electricity Consumed by Refrigerator Per Day – Shocking Truth vs Smart Savings

If you have ever wondered How Much Unit of Electricity Consumed by Refrigerator Per Day, the answer may surprise you. A refrigerator in any Indian house is always running 24 hours a day, keeping our milk fresh, vegetables crisp, and water cool.

But it is also an increasing factor in electricity bills- usually, between 1 and 2 units of electricity per day from a small single-door fridge and 3-4 units for a large double-door one. Let us understand the breakdown of the power consumption of your fridge.

Most Indian modern refrigerators. This image is AI-generated.

Most Indian modern refrigerators use roughly 1.37 kWh – 1.92 kWh of electricity per day, depending on their size, star rating, and application.

Refrigerator TypeWattage RangeDaily Usage (kWh)Units Per Day
Single Door (150–250L)Between 100 and 250 wattsAbout 0.8 – 1.5 kWh1 – 1.5 units
Double Door (250–350L)Between 300 and 800 wattsAbout 1.5 – 3 kWh1.5 – 3 units
Side-by-Side (500L+)500 – 800 wattsAbout 2 – 5 kWh2 – 5 units

Quick formula: (Wattage × Hours Used Per Day) ÷ 1000 = Daily Kilowatt-hour (kWh) energy consumption
Example: A 250-watt refrigerator running 24 hours → (250 × 24) ÷ 1000 = 6 kWh monthly ≈ 180 kWh/year

Factors That Affect Your Refrigerator’s Power Usage

Even two refrigerators having the same size may have different electricity consumption depending upon:

  • Star rating: The higher the BEE star rating, the less electricity is consumed.
  • Age of the fridge: Older models can account for between 15% and 27% of the household’s total electricity consumption.
  • Fridge Door Habits: Using the fridge cupboards too often means that the compressor has to work harder.
  • Ambient Temperature: During the hot Indian summer, refrigerators have to work much longer to maintain the cooling.

How to Reduce Refrigerator Electricity Consumption

According to my own experience (we replaced our old 15-year-old fridge last year), these tips have made a noticeable change in our electricity prices.

  • Choose Energy-Efficient Models – Go for a refrigerator with at least a 4-star or 5-star rating.
  • Put It in a Cool Place – At any rate, direct sunlight or gas stoves are not advisable.
  • Keep It Filled Up to 70–80% – An empty refrigerator will lose cooling faster, and when overfull, airflow will be blocked.
  • Check Door Seals – If they’re loose, then they consume more energy.
  • Keep Your Fridge Defrosted-For non-frost-free models.
