Do you agree with gain from whattomine or coinwarz ?
I'm experiencing a massive difference between estimated and real.
My RX 480 gives me 29 Mhash, i'm using claymore so i have 1%fee, mining on nano pool, so another 1% fee.
In 24H, according to previous quoted calculators i should get >0.16ETH, but i've collected only 0.13 ETH.
0.03 ETH is more than 15% of my earnings..
Probably some of my math is wrong, correct me please
I have found the whattomine site pretty accurate if you input the correct values. I use Claymore too with the 1% fee built in and mine at Ethermine (also 1% fee).
What I do is input what the pool shows my miner doing for the past 24 hours. For an good example, and to counteract the arguments in this thread that older cards are not profitable, I will use a rig I have that uses 4x R9 270 cards, which are
not the most efficient.
So this rig reports locally on the miner that it is hashing at 53.5 MH/second (about 13.3 MH/s per card), but on the Ethermine pool I show a 24 hour average of only 50.5 MH/second. At first this may seem low, but consider that the pool figures reflect the 1% mining time reduction that the Claymore software points elsewhere. The rest is typical losses due to rejects, stales, etc. and it probably pretty normal. This is also probably where the most discrepancy comes in from using calculators, is that they don't all account for real-world results and are too rosy on optimal results.
But, getting back to the whattomine calculator, when I input the real 50.5 MH/s value and add the 1% fee for the pool, I end up with it showing I earn about 0.340848 ETH/day. I compare this to what Ethermine shows I earned and I can see it is close, but Ethermine is still a bit lower. This is where luck comes in. Clicking on the "Luck" tab on Ethermine site, I can see that the recent luck has only been about 97%. Taking 97% of the whatomine figure puts me almost exactly at my Ethermine results.
As far as profitability, this "inefficient" rig draws 600 watts for only 50.5 MH/s real pool hashrate, but even with $0.10 electricity it is grossing $4.59/day, with power cost of $1.44 and netting a nice profit of $3.15/day.
Even if we crank up the electricity price to a high $0.15 rate, we are still netting a comfortable $2.43/day in profit. Even at $0.20 power, we can earn a modest $1.71/day in profit, so yes mining is still quite profitable.
One of my more efficient rigs consisting of 4x RX 470 that produces 88 MH/s with a power draw of only 660 Watts for the entire rig, pulls in a gross of $8.00, uses $1.58 in electricity, and nets a nice $6.42 in daily profit. Even at $0.20 electricity, this rig would yield a daily profit of $4.83.
