The staking rate is 10% per year. That means that you should generate approximately 95 ETHD per year. The problem is that you will need to buy 2K ETHD if you plan to run a masternode. The second stage will have a 2:1 swap. That means that every 2K ETHD will be swapped for 1K ETHD. I don't think that a lot of people read that part of the white paper. You'll have to wait and see what the new white paper that's coming out says.
