If you’re interested in earning $300-400k/year after working for a BigCo for 4-5 years, Seattle isn’t going to work out to a better net savings/year.
I think it’s perfectly fine to max out at $100-150k. You’re still extremely rich by any standard. And startups in The Bay Area will pay you vastly less regardless, so Seattle may well be a better place for startups.
But I think you’re doing people a disservice if you convince them they’ll save more money working in Seattle than the Bay Area.
I have hired many people who worked for Seattle BigCos, and I know many people who have gotten offers from Seattle BigCos trying to lure them away from the Bay Area.
And I’ve chatted with people doing competitive analysis on what offers to make to engineers.
The Bay Area generally has 20-30% higher total comp after the first 2-3 years.
Somewhat amusingly, the headline salaries are pretty similar, which makes people think total comp is similar. It’s all about the bonus and RSUs.
