Exhaust Your Federal PhD Student Loan Options First
If you have to borrow using PhD student loans, always max out federal student aid as your first source of funding. Federal student loans tend to be cheaper, provide more repayment flexibility, and come with other borrower perks, such as the potential for loan forgiveness.
The Department of Education offers Direct PLUS Loans to graduate students for the purpose of covering advanced education, and if you’re eligible, you could potentially borrow up to the school-certified cost of attendance, less any grants or scholarships you’ve received.
Unlike some federal loans, however, Grad PLUS Loans aren’t available to you if you have an adverse credit history, and you’ll need to undergo a credit check to prove that you don’t.

5 Best Private PhD Student Loans
After maxing out your federal student loans, you may find you still need more money to pay for your doctoral degree. If that’s the case, you’ll need to look into getting private PhD loans.
Private student loans tend to come with higher interest rates, can be harder to qualify for, and repayment plans are less flexible. However, they can cover shortfalls in funding that otherwise might make getting your PhD impossible.
LendEDU has ranked the best PhD student loan providers to help you find options that could help you fund your degree. Here are the five highest-rated lenders that offer student loans to PhD students.
