Note:

For new miners, the electric cost of supplying power to the miner needs to be known and added to the production cost. A high hash rate and high power consumption of any mining device show a high level of power supply needed for the mining to be done. Electric charges vary with location, so locations with high electric costs will affect the product's profitability.
