Annual Savings vs Electricity Rate

How to Calculate Energy Star Savings

Energy Star certified products meet strict energy efficiency guidelines set by the EPA.

Formula

Annual Savings = (Standard kWh - Energy Star kWh) * Rate

Lifetime Savings = Annual Savings * Lifespan

Typical Energy Star Savings

  • Refrigerator: 9-10% less energy
  • Clothes washer: 25% less energy
  • Dishwasher: 12% less energy
  • Air conditioner: 15% less energy
  • Example Calculation

    An Energy Star refrigerator using 350 kWh/year vs standard at 500 kWh/year over 12 years at $0.15/kWh.

    1. 01Energy saved: 500 - 350 = 150 kWh/year
    2. 02Annual savings: 150 * $0.15 = $22.50
    3. 03Lifetime savings: $22.50 * 12 = $270
    4. 04Energy reduction: 150 / 500 * 100 = 30%
