Here's the breakdown for a 2nd Lt in Pilot Training at Del Rio.

Basic Pay (Taxable)- 2469.30/ month
Flight Pay (Taxable)- 125.00/ month
Basic Allowance Sub (non taxable)- 192.74/ month
BAH (Del Rio- Non taxable)- 829(w/ dependents) 642 (Single)

You would probably live on base at UPT. Therefore, you would not receive BAH. You would also not have any power bills, water bills, etc. Only cable and phone. Therefore, about $3428/ month for a single guy. If I remember correctly, lost about 8% of it to tax. So take home about $3100 per month. This proves most of our points of not joining the military for the money. Join it because you want to kill bad guys and break their ****!! Good luck.
