So regarding % wise, I don't know. Because DoD and DoVA has it's seperated funding which added together totals slightly over a trillion. The DoD Healthcare and Pensions costing is part of it's Personnel costings, where some of the breakdowns aren't fully available in the public domain. Or it's broken down in some 500 page DoD PDF that I haven't managed to sift through.
But total numbers wise: Personnel Salaries + Active Personnel Healthcare + Pensions + Housing + Veterans Healthcare totals to a number just short of 600 Billion USD

So let's go through all the chronic shortages of the US right now:
1) Shipbuilding - This is the biggest problem facing the US military right now. There are a lot of reasons that factor in to why US military shipbuilding is in catastrophically bad shape right now, but my main gripe is with the Jones Act and the general lack of political willingness to subsidize the building of new shipyards. This, plus the general malaise of the civilian shipbuilding industry has made the USN unable to expand. In the Cold War, the US could field 600-700 ship fleets. Now, the US Navy is aiming to reach a 400 ship navy by the end of the 2030's. To put into context of how bad this problem is, China at the moment is able to build 6 destroyers a year, the US is able to build 1.5. China is able to build 5 Submarines a year, US is able to build 2. China has put out 2 new aircraft carriers (with a further one currently undergoing early stage trials) in 6 years, US in the same time frame has been able to build the USS Gerald R. Ford. In the past 5 years, China has built 21 modern frigates. US has built....none. China has built 8 LHD/LHA's, US has built 2.5. You see how the disparity here is incredibly, incredibly concerning?
2) The state of the Navy in general. There are so so many things wrong with the Navy right now that requires sustained investment of hundreds of billions in order to begin to rectify.
-There is still no active US Frigate since the Oliver Hazard Perry's retired, and until the Constellations are built. This means that bigger ships have to do the duty of frigates, which leads to overworked hulls, degredation (Which leads to further increased costs of R&R) as well as crew fatigue.
- There is still no DDG(X) Program to replace the 45 year old Arleigh Burke hull. Arleigh Burke's have reached the end of their design lifespan.
- There is still no LSC design to replace the Ticonderoga class which reached the end of its service life. LSC should have been completed a decade ago, but due to budget cuts there was never a replacement for the cruisers. What the Navy have done instead is to turn the LSC program into Arleigh Burke Flight III, which is to cram even more engine power into a 45 year old hull, put in flagship modules and add a few more missile tubes and a more power radar to replace the Ticonderga. It's not a real Tico replacement, just a short term stop gap.
- There are not enough sailors, which has led to many fatal accidents this past 5 years, especially to the 7th Fleet.
- There are simply not enough ships in general, again mainly to the 7th fleet, which has led to some horrendous faults.
- The navy simply do not have the money to buy enough F-35C's. What they're doing is praying NGAD FA(XX) comes through and they will buy those instead. If it doesn't, the Navy is screwed in a Pacific war where it has to rely on Superhornets against 5th Gen Chinese Aircraft.
Oh, you know whats funny about the last point? The Navy is delaying its FA(XX) program because...it cannot afford it due to so many other pressing urgent issues! Furthermore, due to the obsolescence of the existing FA18 Hornets, the production lines for them have been shut down. So Navy have no way of procuring current Naval Air Wings, cannot afford F-35's and cannot afford to research FA(XX) to replace the FA18's.

3) The Air Force is not faring any better.
- There is no long term primary Air Superiority Fighter in the works. The primary project for this just got suspended, partly due to lack of funding. Without Airforce NGAD, the USAF is incredibly vulnerable. The lifespan of the F-22 is coming to an end soon and the USAF are still going to have to rely on its baseline F-15's from the 1970's as the main frontline Air Superiority Fighter (Granted, F-15EX is exponentially more modern and better than F15-C's). Congress were so worried USAF were going to retire the F-22 due to lack of scalability and modernization that they actually put a law in that prevented F-22's from being retired.

- Loyal Wingman integrated networked drones is delayed. This was meant to be the future of the USAF - F-35's and NGAD's supported by autonomous cheap fighter jets that didn't require a pilot and was fully AI controlled. Well, this has been delayed by about 2-3 years now.
https://breakingdefense.com/2023/12/no-bucks-no-bang-secaf-kendall-warns-24-budget-logjam-could-cost-a-year-on-ai-fighter/#:~:text=REAGAN NATIONAL DEFENSE FORUM — The,Force Frank Kendall warned today.
- Lack of any deep penetrative tactical bomber on the horizon. B-21 is a strategic bomber, F117's have been retired, F-35's can do it but are not suitable entirely for that purpose due to lack of payload size, B-1 Lancer's are a mess. There is nothing that will allow for Tactical level deep penetration bombing missions against critical infrastructure. There isn't even a R&D/Research Program to overcome this problem right now.
- Delay in AIM-260 A2A missile. This is meant to be the counter to the PL-15 but it's offset with delay after delay, due to lack of congressional funding and no money to be spent on it.
- The KC Tanker procurement plan is an absolute mess right now.
4) The Army is in okay shape, but it's undergoing a massive modernization program that is being completely underfunded.
- Old M2A2 Bradleys need replacing. XM30 has been given the go-ahead, the Army says they need to procure 4000 of them, just for active service (Forget reserves and backup vehicles). It was meant to be done by 2014, but due to funding issues, got delayed and delayed and the final contract hasn't even been given due to this.
- M113's are being replaced. In 2012 the US Army proposed they need 3000 AMPV's (M128(X) series). It never got funded so we're now in 2024 and it took until 2023 for the FIRST BATTALION of AMPV's to get delivered to the Army.
- MBT Modernization program is going incredibly slowly. It's now a competition between AbramsX and AbramsM1A3X. IF it gets funding, a new MBT might be in service by 2030.
- M109 Paladin's have been earmarked for replacement. A project called M1299 Howitzer was earmarked. Cancelled in 2024. Why? Too expensive relative to its value.

- Light Tank Project finally saw the light of day, with the M10 Booker finally entering service. About 5-8 years too late and not enough funding for mass production yet.

Man, It's really late and I could go on and on and on about all the issues that need resolving (primarily with desperately needed funding), but I'd be here all night.
I haven't even touched on SM-6 production bottlenecks, LRASM low rate production, Standard Issue Rifle replacement delays and all the other myriad of problems plaguing the US military right now.
The US military is in its worse shape relatively since about 1975.
