Ethereum Mining Trial

So this week-end I did an experiment with Ethereum Mining. The first thing I did was use a calculator. Here’s one from

Now according to this calculator, I should make around $36 bucks a month for my Nvidia GTX 1060 Card. Well, I did an experiment and after 28 hours I made $1.10. This comes out to about $0.04/hour or $0.94/day, but I’m actually paying $0.49 in electricity cost. So the net is $0.45/day or $13.71 per month. This makes the calculator wrong by about 263%. This link above has net profit at $1.20/day. So the hash rate was a lot lower than stated both on miner and on other estimates for this card.
