Formula

#
Formula principal
Monthly Cost=Watts×Hours/Day×301000×Grid Rate\text{Monthly Cost} = \frac{\text{Watts} \times \text{Hours/Day} \times 30}{1000} \times \text{Grid Rate}

Como funciona: Converte watts em quilowatts, multiplica pelas horas de uso para obter kWh consumido, depois multiplica pela tarifa por kWh.

Exemplo Resolvido

Ar condicionado de 1500W, 8h/dia, R$0,80/kWh -> 1,5 x 8 x 0,80 = R$9,60/dia.
