Gold IRA Fees - Help me compare these different structures, getting confused in my old age!

Okay, so I've been eyeing a bit of a rebalance in my Gold IRA. Been with my current custodian for about 12 years now, ever since I retired from ExxonMobil and rolled over a good chunk of my 401k. Most of my gold is in allocated storage, good old American Eagle coins, but I’m looking at some of the newer offerings, maybe some European sovereign coins, and honestly, the fee structures these new companies are quoting are making my head spin a bit. Back in '12, it was pretty straightforward, set annual admin fee plus storage. Now it feels like there’s a fee for everything.

My current setup is with XYZ Custodian (not naming names, but they’re one of the big ones you hear on the radio ads). I’m paying a flat $250 annual admin fee and then $150 a year for segregated storage on my ~1,000 oz of gold. So $400 all in, which for a seven-figure portfolio, felt reasonable enough. But I’m seeing some places quote percentage-based fees, like 0.15% to 0.25% of asset value, combined with transaction fees, shipping fees, insurance fees, audit fees… it’s a lot to keep track of. Does anyone have a good mental model for comparing these? Or am I just overthinking it now that I’ve got more time on my hands?

I understand that moving metals involves some costs, obviously, but I want to make sure I’m not getting nickel-and-dimed into oblivion. For someone with, let's say, $1.5M in gold assets (just an example, not my exact number but in that ballpark), how do you even begin to calculate whether a flat fee of $500 is better than a 0.2% fee from a different firm? Especially when some firms have higher upfront costs but lower ongoing, or vice-versa. I'm based here in Houston, so access to certain depositories might be a factor too, though I mostly rely on trusted shipping for anything too crazy. Any Texans here with insights on particular local custodians?

It's always been about capital preservation for me, especially after seeing a few downturns in the energy sector over the decades. Gold’s been a rock for my family. Just want to make sure I'm being as efficient as possible with my investment vehicle. What are some of the hidden fees I should really be looking out for? What's your personal threshold for acceptable annual fees on a substantial gold holding?
