A role might say it has a $150,000 “salary” but if someone has say $300,000 in RSUs on top of that then they’re really making $450,000 with a $150,000 “salary”.
Eg in the US employers must publish the “salary” for certain visa applicants, but those numbers are often only a small fraction of total comp because they exclude equity-based compensation. Given that different companies give different cash/equity mix in their comp plans this leads to a lot of misleading data points about the pay of various companies. One company many look like it it’s more (because it does in cash salary) but actually the total pay relative to others is much less (eg because they give out less stock).
