How It Works
Enter Wattage

Set Usage Hours
Enter how many hours per day you use the appliance. Be realistic for accurate estimates.
Specify Days
Enter the number of days per month you use the appliance. Use 30 for daily use.

Pro Tips for Energy Management
Track Actual Hours
Monitor real usage for a week before calculating. Estimates are often wrong - a TV 'always on' might only be 4 hours actual viewing.
Consider Seasons
AC and heating costs vary dramatically by season. Calculate separately for summer, winter, and mild months.
Check Standby Power
Many devices draw power even when 'off'. Add 5-10% to your estimate for phantom loads, or use smart power strips.
Compare Over Time
Calculate costs for energy-efficient alternatives. An LED vs incandescent bulb saves $10+/year per bulb.
