Electricity bill calculation

Energy consumption calculation

The energy E in kilowatt-hours (kWh) per day is equal to the power P in watts (W) times number of usage hours per day t divided by 1000 watts per kilowatt:

E_(kWh/day) = P_(W) × t_(h/day) / 1000_(W/kW)

Electricity cost calculation

The electricity cost per day in dollars is equal to the energy consumption E in kWh per day times the energy cost of 1 kWh in cents/kWh divided by 100 cents per dollar:

Cost_($/day) = E_(kWh/day) × Cost_(cent/kWh) / 100_(cent/$)
