How much electricity does a refrigerator use per day?

A typical 250–350 litre frost-free fridge uses about 0.8–1.2 units (kWh) per day, depending on its star rating. A 5-star model uses around 0.8 units/day; a 3-star around 1.2 units/day. Single-door direct-cool fridges use less, about 0.4–0.7 units/day.

How much does it cost to run a refrigerator per month?

At ₹8 per unit, a 3-star 250–350 litre fridge (about 430 units/year) costs roughly ₹287/month, while a 5-star model (about 280 units/year) costs about ₹187/month. Larger 350–500 litre fridges cost ₹250–375/month depending on star rating.

How many units does a refrigerator consume per year?

Indian fridges carry a BEE star label showing annual energy consumption in kWh/year. Typical values: single-door 150–250 units/year, 250–350 litre frost-free 280–430 units/year, and 350–500 litre 380–560 units/year. A higher star rating means fewer units for the same size.

Is a 5-star refrigerator worth the extra cost?

Usually yes. A 5-star fridge uses 25–35% less electricity than a 3-star of the same size. For a 300 litre model that is about ₹100/month or ₹1,200/year saved, so the higher purchase price typically pays back in 2–4 years — and the fridge runs for 10+ years.

How can I reduce my refrigerator's electricity bill?

Set the thermostat to medium (not coldest), keep the fridge 70–80% full but not overpacked, let hot food cool before storing, check the door gasket seals well, keep it away from the wall and direct sun, defrost regularly, and choose a 5-star inverter model when replacing.

See how many units your fridge uses and what it costs — per day, month and year — for your size and star rating.

🧊 Your fridge runs 24×7, all year. It is often the single biggest always-on load in the house. A 3-star vs 5-star choice on a new fridge can mean ₹1,000–1,500 difference every year for a decade.

How This Calculator Works

Every fridge sold in India carries a BEE star label with its annual energy consumption in kWh/year. That single number already accounts for the compressor cycling on and off all day.

We divide it by 365 for daily units and apply your tariff. For the most exact result, type the annual units printed on your fridge's label into the box.

How Refrigerator Electricity Consumption Is Calculated

A fridge's compressor switches on and off all day, so you can't simply multiply its wattage by 24 hours. Instead, India's BEE star label gives a tested annual consumption figure (kWh/year) that already includes this cycling. That is the most reliable basis for cost.

Units per Day = Annual Units (kWh/year) ÷ 365 Units per Month = Annual Units ÷ 12 Cost per Month (₹) = Units per Month × Tariff (₹/unit) Cost per Year (₹) = Annual Units × Tariff

Worked Example — 5-star 300 litre fridge

Annual consumption (BEE label): 280 units/year | Tariff ₹8/unit

Units per Day = 280 ÷ 365 = 0.77 units/day
Cost per Month = (280 ÷ 12) × ₹8 = ₹187/month
Cost per Year = 280 × ₹8 = ₹2,240/year
A 3-star equivalent (~430 units) would cost ₹287/month — ₹100/month more.

Approximate annual units and monthly cost at ₹8/unit. Actual values are on your fridge's BEE label.

Fridge	3-Star	4-Star	5-Star
Single-door (150–250 L)	230 u · ₹153/mo	185 u · ₹123/mo	150 u · ₹100/mo
Double-door (250–350 L)	430 u · ₹287/mo	350 u · ₹233/mo	280 u · ₹187/mo
Double-door (350–500 L)	560 u · ₹373/mo	460 u · ₹307/mo	380 u · ₹253/mo
