2015 paychart, courtesy of
www.dfas.milO-1 less than 2 years - $2934.30
BAH - $1341.00
BAS - $253.38
Total gross - $4528.68
E-4 less than 2 - $2019.60
BAH - $1146.00
BAS - $367.92
Total gross - $3533.52
So that's almost a grand a month more for the officer before taxes. The increase in base pay
more than "basically offsets" that $111 difference
.
For a more accurate look after taxes, I used a salary calculator located here
http://www.paycheckcity.com/calculator/salary/
I chose single, 1 claimable allowance, paying SC state taxes (7%, it sucks), and did not include your BAS and BAH because neither of those are taxable.
O-1 less than 2:
$3631.10/month, $1815.55 per paycheck
E-4 less than 2:
$2956.66/month, $1478.33 per paycheck
Difference after taxes - $674.44, which is not the initial 1k, but is still much higher than that difference in BAS.
Also, at your two year point as an officer, contingent on you not doing anything stupid, you receive a promotion to O-2. The average enlisted, if they don't reenlist or have been fortunate to have made E-5 via the exam, will still be an E-4.
So at that point, based on 2015 pay for an O-2 over 2 of $385020 with the same BAH zip code for comparison sake($1497.00 for O-2 over 2 without dependents) and you get:
O-2 over 2:
$4363.02/month, $2181.51 per paycheck
E-4 over 2:
$3023.68/month, $1511.84 per paycheck
Difference after taxes - $1339.34. After 2 years, the difference has almost doubled.
Lastly, if that enlisted guy/gal gets advanced and is actually getting paid (cause they can go up to 6 months in their new rank before actually getting paid for it), BAH of $1278 and same BAS you get:
E-5 over 2:
$3303.74/month, $1651.87 per paycheck
Difference after taxes - $1059.28
Hopefully I have provided a info source (the pay calculator site) that gives you a better estimate. As to the actual why enlisted BAS is higher, I can't recall the reasoning given. On a side note, on the carrier (guessing same on a boat), the officers paid monthly dues to the wardroom, which was usually a little more than their BAS. Not sure how it will work for you as a NUPOC instructor.
Best of luck and congratulations on being selected for this highly competitive position.
