I use google and searc for "ANN Sparks" and get the link to the coin announcement:
https://bitcointalk.org/index.php?topic=2634042.0Here is info about coin:

So now you know that it is Neoscrypt, 120 seconds/block and miners get 50% of 18 Sparks per block. So all miners get 9 sparks on every block. 120 seconds per block means 30 blocks per hour which means 720 blocks per day. Total rewards to miners is 9*720=6480 Sparks/day.
Then you can check total network hashrate with a block Explorer. It say it is around 16.2 GH/s right now
http://explorer.sparks.gold/So that means in order to get 6480 Sparks/day you need to own the total network hashrate of 16.2 GH/s.
Now you need to check your own mining hashrate. I understand that you have 4 MH/s
Nethash (according to block Explorer): 16.2 GH/s = 16200 MH/s
Your part of total nethash is 4/16200.
So one day you get your part of total mining reward:
6480 * 4/16200 = 1.6 SPK/day
With your example nethash is 18.2 GH/s would give 1.42 SPK / 24 h
This is a rough approximation.
Another way is checking what the mining pool say.
Altminer.net say reward 9SPK, pool hash rate 819.3 MH/s and TTF=42 min (right now when I check).
So with 819 MH/s you win one block reward of 9 SPK each 42 minutes.
Your part of pool hashrate is 4/819. So your TTF is 819/4 * 42 minutes = 8600 minutes
You need 8600 minutes to get 9 SPK on the pool. 8600/(24*60) Days = 5.97 Days
So you get 9/5.97 SPKS per day which is 1.5 SPK/day
But you have a pool fee of 0.9% but that is so small that you don't have to take into account in this rough estimation.
The values change all the time but a rough estimation is 1.5 SPK/day.
1 SPK = $14.87 so that would make it $22.3 / 24 h.
