There are reasons for upping the denominator that high: if you're regularly reporting 50K in balances a month on personal credit (some do typically business / reimbursible expenses that show up on personal) then having the additional buffer is useful.
Most people aren't. I've occasionally reported balances between 6 and 10K on various tradelines, with only 34K in aggregate at the time and wasn't a huge deal. When I'd first done the math back in call it 2012 here I'd figured 50K was a good number for me... but got a little bit surprised on my last spree: I applied for a few tradelines and they were granting $20K or higher CL's expaning my limits to around 126K with just the addition of 5 more accounts (and one of those was a JCB Makurai at 3K which surprisingly was a pretty good starting limit compared to historical averages).
This is with my file, and one can see scores in my signature though I was probably 20-24 points higher FICO 8 from pretty installment utilization at the time, and my income isn't extraordinary though at the time it was around 14% nationally. Point being limits aren't really hard to generate, when Chase, Cap1, and Penfed suddenly all decide together that I'm "good enough" on some non-collusive measurement to receive 20K+ lines, it's just a matter of time and making the applications if I so cared to, but hitting a limit goal isn't important for me so I don't try. As is I'm tempted to close 42K in limits at this point, job changed so the hotel card isn't getting used, and I have access to a HELOC now so the 10% PLOC really isn't worth financing anything on. Oh well, mistakes were made.
Anyway, $1K on a $5K line is absolutely irrelevant to the scoring algoithm btw. Individual card utilization doesn't appear until much higher, and aggregate is the dominant revolving utillization calculation anyway.
What kind of income do you have to support that? I have a feeling I would get laughed at with my $50k job.
AMEX BCE $15k // IHG Rewards $5900 // USAA MC $3000 // AF BANK $1000
