Depends heavily on your model of expected lifetime earnings, compared to your age.

The answer will be very different for each of the following people:

• Someone in their 7th year of a trades career after two years of trade school/apprenticeships, who expect to be able to earn about twice their current income by the time they retire at 60.
• Someone in their 5th year of a white collar career, who is coming up on finally paying off their undergraduate student loans, and expects to climb the corporate ladder to where they're making 3-4 times what they're currently making today.
• Someone in their second year of medical residency, who has 6 figures in student loan debt, and only makes about $60k now, but expects to be making an inflation adjusted $250k-400k per year for most of the next 40 years.
