Calculation method
How this estimate is calculated
Cost = (watts ÷ 1,000) × hours used × electricity rate

What can change the result
- The entered wattage represents average power while operating.
- A month is averaged as 30.4375 days.
- The electricity rate is entered in dollars per kilowatt-hour.
For the most useful estimate, use measurements from a plug-in energy monitor, connected charger, vehicle dashboard, or product energy label whenever available.
