Appliance Energy Calculator

By using Appliance Cost Calculator (operated by Pond Software), you agree to these terms. They're short and written in plain English.

Informational use only

Everything on this site — the calculators, guides, and comparisons — is provided for general informational purposes only. It is not professional financial, legal, tax, engineering, or electrical advice, and it is not a substitute for it. For decisions about your electrical system, your appliances, or your budget, consult a qualified professional such as a licensed electrician or your utility provider.

Estimates are estimates

The costs this site produces are calculated from the inputs you provide — wattage, hours of use, and electricity rate — using a simple, transparent formula. Real-world costs depend on many factors we can't see, including:

your utility's actual rate, rate tiers, and time-of-use pricing;
fees, taxes, and surcharges on your bill;
the true power draw and efficiency of your specific appliance, which can differ from the typical pre-loaded wattage;
how the appliance cycles on and off, ambient temperature, and age.

Because of this, the figures on this site are approximations, not guarantees. Always treat them as a ballpark and check the wattage label on your own appliance and the rate on your own bill for the most accurate result. The default rate of $0.16/kWh reflects the 2024 U.S. national average and may not match your area.

No warranty

The site is provided “as is” without warranties of any kind, express or implied. While we work to keep wattages and rates accurate and current, we don't warrant that the content is complete, error-free, or up to date. To the fullest extent permitted by law, Pond Software is not liable for any loss or damage arising from your reliance on the estimates or other information on this site.

Third-party links

The site contains links to third-party websites, including affiliate links to retailers such as Amazon. We aren't responsible for the content, products, or policies of those sites. See our affiliate disclosure and privacy policy for details.

Changes

We may update these terms from time to time. Changes take effect when posted, and the “last updated” date above will reflect the most recent version.
