After transitioning from guard to active duty can I convert my MUTAs towards active duty retirement?

When you look at your NGB 23 under the column that says AD points, each one is worth one day. So, your AT's, activations, and schools where you were on active duty all count towards an active duty retirement. Your Career Counselor is the subject matter expert on it and you probably need a DA 1506 from them after coming back onto AD.

Yes, each UTA will count as one retirement point, so a MUTA-4 will be 4 points. This is done when you are ready to retire and sit down with the retirement specialist.

If you are coming from the national guard you should have a RPAM. This will basically summarize all of your points and it should be automatically uploaded to your Iperms annually. If you look at mine you could see the difference between active duty points which means how much I can use towards my time to retire from the regular army and my retirement points which means I will have more retirement points than years. When I spoke to a career counselor it basically means that I get the points but not the time for service. when I hit 20 years I will basically get paid for 22 years of service based on having points that only counted for pay.
