Energy Star Savings Calculator

How much does ENERGY STAR actually save you?

Compare your current fridge's annual kWh against an ENERGY STAR model — at your own electricity rate — to see annual dollars saved, 10-year savings, and the CO2 footprint cut.

Under the hood

Two kWh values, one rate.

Reference numbers come from DOE energy-conservation standards, the ENERGY STAR certified product database, EIA average residential rates, and EPA eGRID grid emission factors.

  1. 01

    Annual savings = (current − ENERGY STAR) × rate

    kWh saved per year, multiplied by your electricity rate, gives the honest annual dollar savings — no spread, no fees baked in.

  2. 02

    10-year projection

    Industry-typical refrigerator service life is ~10 years; we scale annual savings linearly across that span.

  3. 03

    CO2 + tree equivalents

    kWh saved × 0.86 lbs CO2/kWh (EPA eGRID national average), then ÷ 48 lbs/yr per mature tree (EPA Greenhouse Gas Equivalencies).
