No it is not. Mining costs per coin are in the range of 80-120$ (without the garbage overpriced miners without ROI).
Cost of production at current difficulty (43.9B) without including capital investment (all hardware, space, cabling, etc.), the most efficient hardware available and .08/kWh electricity is in the range you describe.
But, if you're a manufacturer completely funding all of your R&D and infrastructure with retail markup hardware sales you're just barely getting there, and any new buildouts will have to be fully financed. The real cost for them currently is probably around twice your estimated range.
Keep in mind that retail markup hardware sales are disappearing at the current exchange rate
