I did a small, simple rudimentary calculation.
With antpool's current hashrate, in the last 3 blocks (the first 3 after the halving) I got paid BTC 0.00000294 per block. This breaks even on maintenance costs for my hashpower when a block takes about 60 minutes.
P.S. I believe this is not a function of the total hashrate
Great job!
In September when you will start new school year (I think 5-6th grade) you will learn wonderful things like percentage etc - that will really help you to switch from simple rudimentary calculation to real high quality ones
