Same electricity rate for both|(1000 ÷ 1000 × 4) − (750 ÷ 1000 × 4)| × 30 days × $0.1831 = $5.49/month

Annual difference uses the unrounded monthly difference × 12. Displayed amounts may differ by a cent due to rounding. Purchase costs and comfort are not compared.

Compare the same job.

A lower wattage does not automatically mean lower energy use. If appliance B takes twice as long, account for the extra time. This calculator compares electricity, not performance, comfort, purchase price, or lifetime costs.

Difference = |kWh of A − kWh of B| × $/kWh

Choose the right comparison

For refrigerators and freezers, select yearly kWh and enter each model’s EnergyGuide figure. For dryers, washers, and dishwashers, select energy per cycle and compare the same load. For other devices, use average operating watts and actual hours.
