It depends on the price on Polo. But it sounds right.

Steem Dollars Are like U.S. Dollars. So right now your post says 8.68
Thats in U.S. dollar.
You get paid 75 percent of it. The other 25 goes to use curators who voted for you and such.
When you do the 50/50 Payout, You get half as Steem dollar (Basically US dollar.)
And the other half goes to Steem power.
