How the appliance operating cost calculator works
Estimate electricity cost, standby cost, and replacement payback for an appliance.
Energy cost = watts ÷ 1,000 × hours used × electricity rate.
Read our calculation methodology and limitations.
Example
Start with the guided example, then replace each value with your own measurements, dates, schedule, price, or plan.
What affects the result
- Rated watts may differ from measured cycling use.
- Utility rates can vary by tier and time.
- Replacement decisions include more than energy savings.
Frequently asked questions
