The star rating in a fridge is a government/industry label that shows how energy‑efficient the refrigerator is and how much electricity it will use over a year.

What is star rating in fridge?

In most countries, fridges get 1–5 (sometimes up to 6) stars on an energy label. Each extra star means the fridge uses less electricity to do the same cooling.

  • 1-star: basic efficiency, higher power consumption.
  • 3-star: moderate to good efficiency, decent savings over time.
  • 5-star (or more in some regions): very efficient, lowest energy use and best long-term savings on your bill.

The label usually also shows annual energy use in kilowatt-hours (kWh), which tells you roughly how much electricity it will consume in a year.

Why does it matter?

  • Saves money: Higher-star fridges cost more upfront but can cut your electricity bill every year.
  • Better for the environment: Lower energy use means a smaller carbon footprint.
  • Runs 24×7: Because fridges are always on, even a small efficiency jump (like 3-star to 5-star) adds up over several years.

A simple rule of thumb: if you can afford it and plan to keep the fridge for many years, go for the highest star rating that fits your budget.

Extra: Star symbols inside the freezer

Some older labels or freezer compartments also use “*” symbols to show how cold that section can go (for frozen food storage):

  • * (1 star): around −6 °C, short-term storage only.
  • ** (2 star): around −12 °C, medium-term storage.
  • *** (3 star): around −18 °C, safe for long-term frozen storage.
  • **** (4 star): below −18 °C, suitable for freezing fresh food and long storage.

This is different from the energy star rating on the outside label, but you may see both on some fridges.
