Which Army Reserve retirement option do I take?

Your points should tell you or give you an idea about how much you receive. Make sure you get all of your points accounted for. Another thing, if you retire before age 60, go retired reserve, if not retired pay will be based off of date retired. Good luck

1SG Michael Blount I can assist.
The site you have listed is one of the correct sites for HRC Retired Reserve calculators.
This one only provides dollars in current day, you can go to one through your HRC account that will provide an estimate at age 60, when reservist are allowed to receive retirement.
In your Records file off the 2x citizen/HRC site you can get your total retirement point count.
If you can't determine it from my comments, ping me via message and I will assist.

Your pension will be based on the number of points so the more active duty you have done, the more it will be vs. someone of the same grade but with less points. Make sure every point is accounted for by HRC. Also, if you have done any mobilizations since January 2008, your retirement will start 90 days earlier for every 90 days you have done. I just got my reserve retirement ID card last week and the DEERS lady told me to contact HRC a year out from my retirement so HRC can cut the final orders. Without those, you will not get Tricare.
