As a fair warning, please do not report your exact current hashrate unless you are really comfortable letting people know that. We definitely want to be even more-cautious about that if any of us are still in it for Proof of Stake. It is not a great idea to disclose your holdings or your earnings rate. And no I am not just referring to the IRS here. They have their ways of finding out anyway.
According to nanopool, before power is taken into account, a miner will earn ~$.0467 per MH/s per day as of this post. At 450 MH/s, that is actually $21, which is certainly not bad. Whattomine is not accurate. It is actually underreporting profits. Unless it's taking power into account on your reported figure.
Looking at my own mining data and matching it against my known power usage, using various BIOS-hacked Hawaii cards and taking my desktop out of the equation (I do not always mine with it), I can make $.0227 per MH/s per day as of today. That would be only $10.21 per day with your hashrate. Maybe you are using more-efficient cards? I do not know. But early yesterday, I was down to $.01 per MH/s per day. And at 450 MH/s that would be only $4.89 per day! Really low. Yes there is that kind of variability on a daily basis. My actual profits after taking power into account, went up by over 100% in the last 24 hours. I am still making a profit, technically, but the only reason I am mining ETH right now is in anticipation of a rise and to avoid the hassle of converting some other currency to ETH on an exchange like Poloniex. Besides, ZEC profits are even further down thanks to the influx of Nvidia miners, so for my cards, its ETH or bust I think.
I would trust a pool reporting profits because they know what they are handing out to their miners based on their hashrates, so they have up-to-the-minute data of what they can actually distribute to their miners. Sites like whattomine are making guesses based on hashrate and difficulty/block times. Of course all the pool reports take their fees - generally 1% or whatever - into account before reporting earnings. And of course Claymore gets his fees if you use his miner.
