I am honestly pretty stuck between the two options and was wondering if someone could explain to me how the retirement system works if say, you separate from active duty at the 11 year or so mark of service and then serve the remainder of your 2o years as a reservist? I know that a lot is up in the air whether you even get the opportunity to go to 20 (0-4 blood baths) but it seems like there are some options in the reserves so I talked to a reserve IP about a month ago and he told me that if you are in a flying job reserve-wise each of your years in the reserves will count as a full year towards your retirement because the flying days add up a little bit more than a regular reserve job. I tried to mess around with the BRS calculator and I know there was actually an example in the JKO about an aviator going to the airlines while flying in the reserves to make 20 and opting in, but I am really with @pourts here that since the government is trying to save money on this retirement system I might want to take a long hard look and make sure opting in to BRS is really the best option. I keep hearing over and over again that you will walk away with nothing if you don't opt in but this seems like somewhat of a fallacy to me because even with BRS most of your retirement is coming from your own personal contributions, which you can do under the old system. Anyone have any experience that can shed some light?
Crap, that's not really what I meant. I was mainly trying to give a compliment before I started an argument. In that context, I was saying you have to use some rosy assumptions for BRS to beat high 3 IF YOU STAY FOR 20. Only about 15% of military stay for 20. I'll link the data if I can find it again, but USAF officer has the highest percentage staying until 20 (~33%), USMC enlisted the lowest (~8% OORAH!), and the other services/ranks in between.
I think the BRS is best for most folks purely for the optionality. Even if you do 20 and only get 40% retirement instead of 50%, it was a fair trade off for the insurance/ option of leaving earlier with all those matching funds. But, if you are an 11 year O-4 in the USAF and have no plans to leave, you should probably be choosing the traditional retirement.
Probably a little on the backside of the power curve at this point since you already lost matching for Jan even if you were to decide today. DFAS/MyPay works super slow. There are lots of great threads on other websites that are more personal finance focused like this one at Bogle Heads https://goo.gl/8Zb5bX ("Nords" at that website is a prior Navy submariner and very knowledgable on military finance, even current issues)
