How to Use This Calculator

Enter your Appliance Power Rating (e.g. 1800 in Watts (W)), Single Session Usage Duration (e.g. 45 in minutes), and Electric Utility Rate (e.g. 0.16 in /kWh). Results update instantly as you type — adjust any value to compare scenarios.

The Formula

Session Hours = Usage Minutes ÷ 60

Session kWh = (Wattage × Session Hours) ÷ 1,000

Single Session Cost () = Session kWh × Utility Rate (/kWh)

Worked Example

1,800 Watt hair dryer running for 45 minutes at 0.16/kWh utility rate:

Session Energy = 1.350 kWh.

Single Session Cost = 1.350 × 0.16 = 0.22 per session (21.60 for 100 sessions).
