If I were going to try to get a bead on what these numbers mean across life circumstances, I'd eliminate rent/ mortgage/ property tax, childcare, charity (beyond supporting your dependents), and (obligate) healthcare - RCCH. Once you rule those out you have a reasonable sense of discretionary impact - although COL is still a big factor, it can be revealing & motivating to know how cheap a happy lifestyle can be. I'm always on the lookout for someone living on less than I do in a way I'd still find fulfilling, because it calls me out & holds me accountable for my areas of opportunity to get more from less.
I don't ever expect to go full-Jacob (of ERE), but if you took RCCH out of the picture I'd be looking at a scant ~$8350 a year of spending, even considering that I way overspend on my data bill (largely due to work, I need redundant high speed data connections), & have a taste for tech toys and fancy imported groceries. Changes in discretionaries I'd expect in RE would be increased spending on groceries due to sufficient time to graze on low-calorie nutrient-rich fresh foods instead of bolting down 2/3 of my meals as mere fuel, and possibly some limited increases to hobby & outing spending; decreased spending on data, car insurance, gas, and work-induced clothing needs. I suspect that will come out slightly under $8k.
