Refrigerator Electricity Cost Calculator
Reviewed by WattCostLab Editorial Team · Methodology and source assumptions are documented below.
Estimate what your refrigerator costs to run per month and per year using the appliance's annual kWh rating or your measured energy use.
Preset values are illustrative only. For a purchase decision, use the model's EnergyGuide/energy label or measured annual consumption.
September 2026 refrigerator efficiency update
Checked September 13, 2026. ENERGY STAR's current refrigerator database lists model-specific annual energy use, which is a better comparison input than nameplate watts. ENERGY STAR also notes that, on average, an old refrigerator uses about 35% more energy than an ENERGY STAR model.
- ENERGY STAR: certified and Most Efficient refrigerators
- U.S. EIA: current residential electricity-price data
The calculator now includes a replacement comparison so you can test the operating-cost difference between your existing refrigerator and a more efficient model.
Best input: annual kWh
For refrigerators, annual kWh is generally more useful than multiplying nameplate watts by 24 hours because the compressor cycles rather than running continuously. If an EnergyGuide label or measured annual consumption is available, use that value.
What changes refrigerator consumption?
- Appliance size and design.
- Age and condition.
- Room temperature.
- Door-opening frequency.
- Temperature settings.
- Dirty condenser coils or poor ventilation around the unit.
- Ice maker and other features.
Compare replacement scenarios
To compare an older refrigerator with a new one, calculate annual operating cost for both annual-kWh ratings. The annual dollar difference provides a simple operating-savings estimate.

Refrigerator energy cost: a worked buying example
The most useful number for comparing refrigerators is the annual energy use in kWh/year. The energy class is a helpful shortcut, but two refrigerators can have different capacities and features, so the label's annual kWh figure gives a better basis for estimating your bill.
Example: Class A refrigerator vs Class C refrigerator
Assume two similarly sized refrigerators on the current A–G scale. These figures are illustrative: Model A uses 110 kWh/year and costs €850 to buy, while Model C uses 170 kWh/year and costs €700. At €0.20/kWh, Model C uses 60 kWh/year more.
| Comparison | Class A example | Class C example |
|---|---|---|
| Annual energy | 110 kWh | 170 kWh |
| Electricity at €0.20/kWh | €22/year | €34/year |
| Purchase price | €850 | €700 |
| 10-year electricity | €220 | €340 |
Extra consumption: 170 − 110 = 60 kWh/year. Over 10 years that is 600 kWh. At €0.20/kWh, the less-efficient example costs €120 more to run.
Does the efficient refrigerator pay back?
The Class A example costs €150 more upfront but saves €12/year in electricity. Simple payback is €150 ÷ €12 = 12.5 years. Efficiency therefore matters, but purchase price, expected life, capacity and features should also be considered.
How electricity price changes the result
| Electricity price | Extra cost for 60 kWh/year | Extra cost over 10 years |
|---|---|---|
| €0.15/kWh | €9 | €90 |
| €0.20/kWh | €12 | €120 |
| €0.30/kWh | €18 | €180 |
| €0.40/kWh | €24 | €240 |
Energy class or kWh/year?
When shopping, compare models of similar usable volume and use the stated kWh/year whenever possible. Older EU labels used A+, A++ and A+++; these should not be treated as direct equivalents of the current A–G classes. For an older appliance, use its actual annual kWh figure rather than comparing letters alone.
What can increase refrigerator consumption?
- Larger refrigerator/freezer volume and ice-making features.
- High room temperature or poor ventilation around the appliance.
- Frequent door opening or damaged door seals.
- Very cold thermostat settings.
- Age, compressor condition and frost buildup.
Try your own comparison: enter the appliance's kWh/year or measured power in the calculator above, then use your local electricity rate to estimate the real annual cost.
Use annual kWh—not compressor nameplate watts
Reviewed September 14, 2026. Refrigerators cycle on and off, so annual kWh from an energy label or a representative measurement is a stronger input than assuming rated watts run continuously. When comparing replacement models, use similar usable volume and features before comparing operating cost.

Translate annual kWh into local cost
Once annual refrigerator energy use is known, the electricity tariff determines operating cost. U.S. users can benchmark the rate with Electricity Prices by State, using EIA electricity-price data.
