Your specific numbers depend on experience, location, employer, and credentials.
When does the salary gap matter most?
For someone choosing between these careers, the $27,000 annual difference compounds:
- Over 10 years: ~$270,000 in raw salary difference
- Over 40 years: ~$1,080,000 (without raises or compounding)
- With 3% annual raises: the gap typically grows because the higher-paid role's raises are also larger in dollar terms
- With investment compounding: the $27,000/year extra invested at 7% over 40 years grows to roughly $5,373,000 — significantly more than the raw difference
But salary isn't everything. Job satisfaction, work-life balance, growth potential, and career switching costs all matter. A career you can sustain for decades beats a higher-paying one you'll burn out on.
