If you would like to estimate how much you can expect to get paid for running your Node during a given month, please follow the instructions here.
Please note that this script won't give you exact values; your actual payout may be slightly different from what you calculated for each Satellite. Also note that the script will estimate what payout you'll receive depending on how long you already have been running the Node on a Satellite. This also takes into account the amount withheld in the initial months which is not immediately paid out.
Please see more details about held amounts in this blog post.
