I'm starting to get annoyed when people say don't do HPSP for financial reasons. It's obviously that most are doing it for that sole purpose. .
You need to be careful how you ccalculate your "NET INCOME" as you are making some gross mistakes regarding loan payback as income in the military.
Average dental salary in a private practice is 200k/year. Out of school you can expect to make a little less than 100k/year. If your not making this money as a dentist you either are a bad dentist or in the wrong part of teh country or chose academics or community work.
But you cannot include student loan repayment into your salary as an officer. YOu have to note you will be paying about 20-30k a year in loan repay. so average start off dentist associate around 100k take home 70-80k. then subtract loan repay. your take home is is around 40-60 k a year.
Which is right around what you would take home as an o3 officer in teh military for first four years out around 40-60 a year. but after those fours years of AD you will be making 20-30 k more a year until your load would be repaid as you have no debt. so instead of around 130k a year take home with no military your pulling in 150k a year with the military.
But you have to also take into account. you CANNOT start a private practice those 4 years in IRR> as if you buy a buisness then get called to active duty,. you are gone for a year and stand the chance of losing customers and possibly buisness. ALso, while on active duty you are once again making 40-60k a year. versus your 150k as practicing dentist. Which is a loss of 100k income for just a year.
NOw chances of IRR call up vary between sectors. but if in army its pretty high right now and probably in the future.
All in all. you basically stand to pull in the same first four years out of dental school then about 20-30k a year for the next 5 or so. But after that your about even.
so if you analyze it correctly there is not a huge $$ advantage to the HSPS over loans as a practicing dentist
However, for the years while in school as you will get 5-10k more a year to live off of.
SO net you gain 140k-190k over a 14 year period of net income for the HPSP versus loans. BUt if you are ever called into IRR for one year it would be 40k-90k, if more than one year, then loans turn out with a 10k to 60k gain in net income.
SO definately DO NOT do it for the money. as over a 15 year period it is no real net gain.
