$250,000 is conservative for the total cost to employ a software engineer in the US. And their expenses are not limited to software engineer salaries of course.
A fair question would be what Google or Apple spend to produce their web browsers. The answers are secrets. $1 billion is a common Chrome development cost estimate in my experience.
