For those of you who really dont know how to calculate your post pay out, just take a look at this.
Curators take 25% of the total post payout while you get 75%.
To know the amount of steem dollars you get, you remove the 25% which is for the curators i.e those that upvoted the post then you divide the remaining 75% by 2 it will give you the number of steem dollars you get.
To calculate the steem power you divide the number of steem dollars you got from the post by the price of steem at that moment, you get the amount of steem power..
Hope i have been able to help some people out
