Refrigerator Electricity Cost Calculator
See how many units your fridge uses and what it costs — per day, month and year — for your size and star rating.
📊 Your Fridge Running Cost
💡 Cut this bill — a 5-star inverter fridge
A fridge runs 24×7, so efficiency matters most here. A 5-star inverter refrigerator can use 30–40% less power than an old model — commonly ₹1,500–3,000 saved per year.

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.
Worked Example — 5-star 300 litre fridge
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.
Refrigerator Running Cost Reference
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 |
| Side-by-side (500 L+) | 780 u · ₹520/mo | 650 u · ₹433/mo | 540 u · ₹360/mo |
* u = units (kWh) per year. Approximate; use the calculator above with your label value.
How Many Units Does a Fridge Consume per Day and per Month?
The same BEE annual figures, broken down into units (kWh) per day and units per month, with the monthly bill at ₹8/unit. A 250 litre double-door fridge uses about 0.77 units/day if it is 5-star and about 1.18 units/day if it is 3-star. A 5-star fridge consumes roughly 12–45 units per month depending on size.
| Fridge size | 3-Star | 4-Star | 5-Star |
|---|---|---|---|
| Single-door 150–250 L (e.g. 190 L) | 0.63 / day 19 / month ₹153 / mo | 0.51 / day 15 / month ₹123 / mo | 0.41 / day 12 / month ₹100 / mo |
| Double-door 250–350 L (e.g. 250 / 300 L) | 1.18 / day 36 / month ₹287 / mo | 0.96 / day 29 / month ₹233 / mo | 0.77 / day 23 / month ₹187 / mo |
| Double-door 350–500 L (e.g. 400 L) | 1.53 / day 47 / month ₹373 / mo | 1.26 / day 38 / month ₹307 / mo | 1.04 / day 32 / month ₹253 / mo |
| Side-by-side 500 L+ | 2.14 / day 65 / month ₹520 / mo | 1.78 / day 54 / month ₹433 / mo | 1.48 / day 45 / month ₹360 / mo |
* Units/day = annual units ÷ 365; units/month = annual units ÷ 12; ₹/month at ₹8 per unit. Change the tariff in the calculator above for your state.
