As in inductive load we will have two types of power consumption. one is real power due to resistive component and other one will be reactive power due to inductive components. so in this case we will find the total power as P= Preal + Preactive.

Where

Preal = Voltage * Current * Power factor

Preactive= Voltage * Current * Sine of Argument of Power Factor

Ptotal = Total Power

Inductive load such as induction motors includes winding resistance and inductive reactance for the load. If you consider the impedance of such load, you will get the apparent power of the load with respect to the supply voltage and current it will draw. The true power tells how much power is dissipated in heat in which we will consider only the winding resistance. With measurements in the circuit for parameters of voltage, current and knowing the power factor rating of the motor or inductive load, we can apply the formula for true power as:

For single phase loads:  Power(P) = Voltage(V) x Current (I) x Power Factor(PF)

For3-phase loads:  Power(P) =1.73 x Voltage(V) x Current (I) x Power Factor(PF)

I hope to have shared some idea, Thanks
