How to Use the Appliance Energy Cost Comparison

Enter the wattage of your current appliance and the efficient model you are considering, along with daily usage, months of use per year, your electricity rate, and the price difference. The calculator shows annual savings and how quickly the upgrade pays for itself.

Finding Appliance Wattage

Check the EnergyGuide label (yellow sticker) on the appliance. It shows estimated annual kWh usage. Dividing by your expected annual usage hours gives average wattage. For air conditioners, use the cooling wattage listed in the spec sheet.

When Does Upgrading Make Sense?

If the payback period is shorter than the remaining lifespan of the new appliance, the upgrade is financially worthwhile. A refrigerator that runs 24/7 can often recoup the cost difference in 3–5 years. Seasonal appliances may take longer.

Frequently Asked Questions

Are there rebates for buying ENERGY STAR appliances?

Yes — many US utilities offer rebates of $25–$300 for purchasing ENERGY STAR certified appliances. The ENERGY STAR Rebate Finder at energystar.gov lists programs by zip code. State and local programs vary.

How do I estimate wattage for a refrigerator?

Refrigerators run continuously. Use the annual kWh from the EnergyGuide label divided by 8,760 hours to get average watts. For example, 350 kWh/year ÷ 8,760 = about 40 W average.
