Part of the mining experience is learning about your coin - not just how to make money. Using a good calculator like
https://etherscan.io/ether-mining-calculator would show that you should be earning about 0.74/mo at present rate assuming an effective 130 MH/s rate. Factor in pool fee and Claymore fee and you can shave off a little more.
The calculator you are using is making serious mistakes in calculation - scroll to the bottom and read the fine print. It assumes 19 second block time - we're way higher than that. It also assumes we're 5 ETH reward when we are at 4.95 and will drop to 3 soon.
