You said “well over 50% of monthly income”, which, in the US, is generally taken to mean gross income, particularly when relating income to housing costs, because of the FHA’s ancient “spend no more than 30% of gross income on housing, or you’re considered cost burdened” rule of thumb.

If you had said “nearly 50% of post-tax salary”, I wouldn’t have quibbled. My point is that no Bay Area programmer living in a conveniently located 1 bedroom is likely to be what the FHA would consider cost burdened, unless they’re working for well below market rate at a startup (and thus are, in my opinion, being exploited by their employer).

Every company I mentioned is public, and RSUs are extremely relevant for total compensation analysis at these companies.

You can't pay rent with pre-tax money, so I don't see how that can in any way be assumed to be related to "% of monthly income" that comes out of net pay.

Maybe it's common in financial circles? But most people I know balance their books based on their take-home, not gross.

If I tell you “I make $100,000/year”, do you interpret that statement as “my after tax income is $100k”? Most Americans don’t.

Americans generally talk about income in terms of gross. This is very disorienting for people from cultures where “income” as a solitary noun generally refers to post-tax income, but arguing with culture isn’t likely to be very fruitful.

It is absolutely true that this is rarely useful for making budgeting decisions, because you have to come up with some inaccurate assessment of after tax net, which is especially tricky with simultaneously progressive and regressive income tax regimes like the US system for high earners.

The cultural variation around internalizing taxes is even more obvious for transactional taxes, where most of Europe lists prices inclusive of VAT but the US lists prices before sales tax; the US affection for communicating costs while ignoring tax and then expressing distress when they finally appear is widespread.

It doesn’t sound like we really disagree on much at the object level, here, we’re disagreeing on semantics (and, I suspect, on tone).
