Keep In Mind…

01

Funding matters

While many Ph.D. programs offer tuition waivers and stipends, funding packages and expenses depend on school and location.

02

The opportunity cost

You sacrifice several years of potential earnings in the workforce.

03

Your career destination

Your individual professional goals can lead to drastically different earnings with the same degree.

04

Program length

Consider how long the degree will take and its completion rate.

Who this actually makes sense for

You need enough funding and a field that will reward your degree. Be willing and able to wait for a payoff.

Conclusion

The Bottom Line

Consider earnings outlook, growth projections, and specific funding packages when choosing which Ph.D. to pursue.
