If you do not know your exact rate, start with the closest preset.
Rate
This is the usage price on your utility bill, usually listed in cents per kWh.
Service charge
This fixed monthly fee is often why the bill feels higher than just usage times rate.

Work & Office
Work-from-home days are set above. Here you specify how many devices are actually running during the day.

How the estimate works
Base usage: Depends on household size and home type (lighting, standby, basic devices)
Appliance add-ons: Additive values for washer, dryer, home office, water heater, AC, etc.
Month adjustment: Proportional correction if occupied less than 12 months
Range: Low and high estimates (plus/minus ~18%) account for habits, insulation, and appliance efficiency
Cost: Estimated usage times your per-kWh rate plus the monthly service charge
Reference values for US household electricity
1 person: often about 4,000 to 6,000 kWh per year
2 people: often about 6,000 to 9,000 kWh per year
3 people: often about 8,000 to 11,000 kWh per year
4 people: often about 10,000 to 14,000 kWh per year
5+ people: often about 12,000 to 16,000 kWh per year
US averages are significantly higher than European ones, driven mainly by central AC, electric dryers, and larger homes. Climate zone, insulation quality, and appliance age all matter.
Based on EIA residential data. Actual values vary widely by state, climate, and utility.
