Refrigerator stars and annual energy figures answer two different questions. The star rating indicates how efficient a model is compared with similar refrigerators, while the kWh/year figure estimates how much electricity that model will use under a standard test. For an apples-to-apples purchase, match capacity and features first, then prefer the model with lower annual kWh. Multiply that figure by your electricity tariff to estimate running cost; your actual bill can differ.
What the refrigerator star rating measures
It is a comparison, not a fixed amount of electricity
On the Australia–New Zealand Energy Rating Label, stars express efficiency relative to comparable products. Australia uses a one- to 10-star scale. The Australian Government describes the rating as how much energy a product uses compared with similar products, rather than as a universal quantity of electricity saved. See the Australian Government explanation of the Energy Rating Label.

A high-star refrigerator is therefore not automatically guaranteed to use fewer total kilowatt-hours than every lower-star refrigerator. The comparison is designed for models with broadly similar capacity and relevant features, such as ice-making equipment and door configuration. A large, highly rated refrigerator can still consume more electricity in total than a smaller refrigerator with fewer stars.
Why capacity and features must match
Refrigerator size, freezer arrangement, number of doors, ice makers and other features affect the energy needed to cool the cabinet. The star score accounts for these characteristics when products are compared within the applicable class. If you compare a 600-litre French-door model with a 300-litre top-freezer model solely by star count, you are mixing different product classes and may draw the wrong conclusion.

Use stars to choose the more efficient option among refrigerators that can meet the same household need. Use the annual kWh number to quantify the expected energy use of each specific model.
What “annual energy consumption” and kWh/year mean
kWh is energy, not power
The label’s annual-consumption figure is expressed in kilowatt-hours per year (kWh/year). A kilowatt-hour is a quantity of energy: using 1,000 watts for one hour consumes 1 kWh. The label is not saying that the refrigerator continuously draws the printed number of watts. Compressors cycle on and off, fans and heaters operate at different times, and the test combines those periods into an annual estimate.
Australian and New Zealand guidance says the refrigerator/freezer calculation assumes operation 24 hours a day and uses standardised test conditions. New Zealand’s EECA explains that the label combines a star rating with annual kWh based on assumed usage and standardised tests in its Energy Rating Label guidance.
Converting kWh into an estimated cost
Use the electricity price on your bill, including the relevant per-kWh energy charge:
Estimated annual running cost = labelled kWh/year × your electricity tariff per kWh
For example, a refrigerator labelled at 420 kWh/year would cost an estimated 126 currency units per year at a tariff of 0.30 per kWh (420 × 0.30). That is an illustration of the calculation, not a typical tariff or a guaranteed bill. Tariffs vary by country, retailer, plan, time of use and taxes, so substitute your own rate.

Compare purchase price and estimated running cost separately. The label supplies an energy estimate; it does not calculate lifetime ownership cost, maintenance, food losses or the value of replacing a working appliance.

Standard tests make models comparable, but a kitchen is not a laboratory. Actual use changes with room temperature, thermostat settings, how often doors are opened, how much warm food is loaded, ventilation around the cabinet, the condition of door seals and whether automatic ice-making is active. A household that keeps a refrigerator in a hot garage may use more electricity than the label estimate, while a lightly used unit in a cool, well-ventilated room may use less.
How to compare refrigerator labels step by step
- Identify the jurisdiction and label. Confirm the country in which the appliance is sold and the scheme printed on the label. A star count, letter class or comparison bar does not have one global definition.
- Set the required capacity. Decide the usable refrigerator and freezer space your household actually needs. Avoid paying to cool unused volume.
- List essential features. Note whether you need an ice maker, through-door dispenser, convertible compartment, extra doors or a particular configuration. Compare models with similar features.
- Use stars within that like-for-like group. In the Australia–New Zealand system, the higher-star model is the more efficient relative choice within the comparable class.
- Read the annual kWh figure. Choose the lower number when capacity, features and test basis are comparable. This is the value used for the cost calculation.
- Apply your tariff. Multiply each model’s kWh/year by your household rate. Keep the result labelled as an estimate and compare it with the purchase-price difference.
- Check the test version when dates differ. Older stock may have been measured under a previous method. Do not treat ratings printed under different test bases as perfectly interchangeable.
What the main label systems mean in different places
The Australia–New Zealand stars are not a worldwide standard. The same refrigerator can have different-looking information, or be tested under a different procedure, in another market.
| Market or programme | What the consumer sees | How to interpret it |
|---|---|---|
| Australia | One- to 10-star Energy Rating Label plus annual kWh | Stars compare efficiency with similar products; annual kWh estimates yearly electricity use under the Australian test method. Start with capacity and features before comparing. |
| New Zealand | Trans-Tasman Energy Rating Label with stars and annual kWh | EECA says the label is developed through the trans-Tasman E3 programme and uses assumed usage and standardised tests. Use the tariff from your own bill. |
| Canada | EnerGuide annual kWh and a comparison indicator | The indicator places a model against the most- and least-efficient products in its class. Natural Resources Canada notes that Canada and the United States generally use similar methods, but the range can differ because the models in each country differ. See the EnerGuide label guide. |
| United States | ENERGY STAR certification is voluntary; it is not a one-to-10 star-count label | For the refrigerator size category described on the current criteria page, a qualifying product must use at least 10% less measured energy than the federal minimum standard. Check the applicable category and current criteria at ENERGY STAR’s refrigerator criteria. |
Do not convert an ENERGY STAR badge into an Australian-style star score, and do not assume that a Canadian comparison indicator uses the same class boundaries as an Australian label.
Why Australian labels can look different on older and newer fridges
Australia changed refrigerator and freezer measurements as it moved to an international test standard. The government notice says the revised method changed measured volumes and comparative energy consumption and was expected to be closer to ordinary home use. It also allowed some already-compliant models to keep displaying the old label for the remainder of their registration period. The details are in the Household Refrigerator and Freezer Energy Rating Label Changes notice.

How to read the label while shopping
| Label item | Question to ask | How it affects a decision |
|---|---|---|
| Star rating | Is this being compared with refrigerators of similar capacity and features? | Use it as a relative-efficiency signal within that group, not as a promise of a particular bill. |
| Annual kWh | What test method, market and label version produced this number? | Use the number for the running-cost estimate after confirming it is comparable. |
| Capacity | How much refrigerator and freezer space is provided? | A larger cabinet can use more total energy even when its star rating is equal or higher. |
| Configuration and features | Does it include an ice maker, dispenser or other energy-affecting equipment? | Compare like with like; otherwise the star comparison can be misleading. |
| Your tariff | What per-kWh price appears on my current bill? | Multiply by annual kWh to estimate your own annual energy cost. |
Australia’s consumer guidance and product-specific refrigerator information are available from the fridges and freezers section. The national energy rating label and calculator page also explains how label information supports household decisions.
Worked comparisons
Two similar refrigerators
Suppose two 400-litre top-freezer models have the same door arrangement and no ice dispenser. Model A has five stars and 360 kWh/year; Model B has four stars and 430 kWh/year. Because the capacity and features are comparable, Model A is the more efficient choice and has the lower estimated running cost at any identical tariff. At 0.30 per kWh, the estimates would be 108 and 129 currency units per year respectively, a 21-unit annual difference. The tariff and currency in this illustration are hypothetical.
A small model versus a large model
A 300-litre refrigerator with four stars may show 300 kWh/year, while a 600-litre refrigerator with the same four stars may show 520 kWh/year. Equal stars do not mean equal total consumption: the rating compares each model with similar products in its own size and feature class. If the household needs only 300 litres, the smaller model may use less electricity overall; if it needs 600 litres, choosing an undersized appliance can lead to inefficient overcrowding and frequent door opening.

Consider the extra purchase price alongside the annual energy difference. If one refrigerator costs 200 currency units more but saves 50 currency units per year at your tariff, the simple energy-only payback is four years. That calculation excludes financing, repairs, tariff changes and discounting, so it is a decision aid rather than a promise that the premium will be recovered.

Treating stars as a global ranking
Mistake: assuming five stars in one country equals five stars elsewhere. Fix: name the jurisdiction and scheme before interpreting the symbol.
Equating kWh/year with watts
Mistake: reading “400 kWh/year” as a 400-watt continuous load. Fix: remember that kWh/year is accumulated energy from cycling components over the test year.

Promising a precise bill reduction
Mistake: multiplying the label figure by a generic internet tariff and presenting the result as a household bill. Fix: use the reader’s current per-kWh rate and call the output an estimate.
Mixing test versions
Mistake: comparing an old Australian label with a new one as though only the design changed. Fix: check the label date or registration and note that measured volumes and comparative consumption changed with the revised standard.
Confusing certification with a star count
Mistake: treating ENERGY STAR as another numeric star scale. Fix: read it as a voluntary US certification against criteria for the relevant product category.
A practical buying checklist
- Confirm the country and label programme.
- Measure the available space, including door clearance and ventilation gaps.
- Choose the smallest capacity that comfortably meets household needs.
- Match ice-making, dispenser and door features before comparing efficiency.
- Record each model’s star count and annual kWh from the same label system.
- Check whether older and newer models use different test methods.
- Multiply annual kWh by the tariff on your electricity bill.
- Compare the estimated running cost separately from purchase price, warranty and repair considerations.
The most defensible conclusion is simple: stars help you compare efficiency within a like-for-like class, while annual kWh lets you estimate electricity use and cost. Capacity, features, jurisdiction, test method and your tariff determine whether that comparison reflects your household.
