Why different payouts from pools

[Ceyflix-Rez]

Can someone explain to me why some pools are more profitable than others even if your hashrate is the same, are the pools ripping people off or there is more to this that I don't know? I use Minerstat calculator and rewards are different

I won't mind calculators that much if I were you, what matters is the hashrate you are getting from your GPUs, I'm getting 31mhs from a single gtx1660super and the reward in dollar fluctuates sometimes which I believe is normal, I use miner stat calculator too but I'm getting the best rewards on nicehash where as nicehash is on fourth rank on Minerstat

There is never a stable pool because rewards goes up and down, they aren't stable or something, it can show 3$ per hour on a calculator and show 2.8$ on another, this doesn't mean a calculator is bad or wrong, mining reward isn't stable and price of the coin you are mining fluctuates as well

Few pools take time to balance their rewards base of hashrates, you got to make sure you stay up to 30 minutes mining on a pool before you can judge if it's bad or not, my 31mhs don't show 31mhs once I click on start mining, it takes some minutes
