Is getting a PhD worth it financially?

Financially, a PhD's worth is mixed: it offers higher lifetime earnings and lower unemployment in some fields (STEM, certain industries) but requires sacrificing 4-6 years of salary (a significant opportunity cost) and can involve debt, with poor returns in weaker markets; the value depends heavily on your field, career goals, and ability to secure funding or high-paying post-grad roles.
