first find out what your average kwh per cent cost is.
typically this can be done by taking total electric bill and divide by used KHW.
IE
300 dollars / 1350 KWH = .22 Cent per KWH
If you have variable electric rates, it be a bit more complicated, but you can average the last few months to get an idea. Then look up what you what to mine and with what equipment. Many on here are mining aeon using extra cpu power they have.
So example would be 4K hash which would be a set of e5-2680 v2 cpu mining would be about .5 aeon per day average. The electric for 2 cpu would be about 350 watts.

350 Watts running 24x7 at 22 cents equals to following:

30 days of mining .5 coins would be about 15 coins. At the current value of 8.00 per coin, you would make a total of 120.00.
Minus the power of 56 dollars would leave you a profit of 64 dollars.
This simple forumla doesnt include things like dealing with heat of equipment, costs of equipment, transaction fees at exchanges and finally taxes. But it give you an idea whether it is worth it for you if you do jump in.
