How this estimate works
A refrigerator cycles throughout the day, so annual kWh is more reliable than multiplying nameplate watts by 24 hours.
- Use your equipment data. Check a label, specification sheet, controller, or energy meter.
- Enter your utility rate. A recent bill is more useful than a national average.
- Test different schedules. Change one input at a time to compare scenarios.
Ways to reduce or refine the cost
1
Use the EnergyGuide annual kWh.
2
Keep door seals clean and replace damaged gaskets.
3
Leave recommended ventilation space.
Transparent methodology
Results use the values you enter and standard energy formulas. They are planning estimates, not bills or guarantees.
Frequently asked questions
How much electricity does a refrigerator use?+
It varies by size, age, features, climate, and condition. Use the model EnergyGuide label.
Does an old refrigerator cost more to run?+
It may. Compare annual kWh rather than age alone.
Should I include a garage refrigerator?+
Yes. Set the number of units to two or calculate each separately.
How to verify this estimate
Best input
Prefer EnergyGuide annual kWh or a multi-day meter reading.
Reality check
Measure long enough to include normal door openings and a defrost cycle.
Important limitation
Room temperature, seals, loading, settings, and ice makers can move use away from the label estimate.
