Energy Usage Calculator

Energy Usage Calculation Formula. To calculate energy consumption follow this simple formula. Energy (E) in kilowatt-hours (kWh) is equal to the power (P) in watts (W) multiplied by the number of hours used (t) per day divided by 1,000 watts per kilowatt. E(kWh/day) = P(W) × t(h/day) / 1000 (W/kW)

Electricity Cost Calculator

power consumption × usage time = power consumed. So we''ll consume 10,000 watt hours or 10 kilowatt hours of power every day. The electricity cost is cost = power consumed × energy price. It''s easy: 10 kWh per day × €0.28/kWh = €2.8 per day. For the annual cost, simply multiply the daily one by the number of days in a year.
