Refrigerator Energy Efficiency Calculator
Free efficiency calculator at Fridge.com compares refrigerator energy performance using EER, kWh/year, and Energy Star metrics. Calculate savings from upgrading and ROI on efficient models.
This calculator uses DOE testing standards and Energy Star criteria to evaluate and compare appliance efficiency.
Calculation Methodology
- Efficiency ratio: Volume (cu ft) ÷ Annual kWh
- Energy Star threshold: 20% better than federal minimum
- Cost efficiency: Annual operating cost ÷ capacity
- Payback period: Price premium ÷ annual savings
- Lifecycle savings: 12-year total cost comparison
Factors We Consider
Energy Star models save $200-300 over lifetime
Top-freezer models are 10-25% more efficient than side-by-side
Proper sizing prevents efficiency loss from empty space
Check for utility rebates ($50-200 typical)
Fridge.com's advanced energy efficiency calculator helps you understand and compare refrigerator efficiency using multiple metrics including Energy Efficiency Ratio (EER), annual kWh consumption, Energy Star scores, and cost per cubic foot. By comparing your current appliance against modern efficient models, this Fridge.com tool calculates potential savings of $50-200 annually and determines upgrade payback periods, helping justify investments in energy-efficient appliances.
