Best Ph.D. Student Loans

Getting your Ph.D. is an endeavor—not just because of the immense work involved. You’ll also need to spend additional years in school and tens—or hundreds—of thousands of dollars paying for it.

You need to be smart about how you fund your schooling, especially if you take out Ph.D. student loans, if you hope to earn a Ph.D. and become debt-free within a reasonable number of years.

This guide will cover using Ph.D. student loans—a specific graduate student loan—to finance your education.

In this guide:

Best Ph.D. school loans

In order to find the best Ph.D. school loans for you, you’ll want to compare some important aspects of each loan option. This means finding a federal or private loan that offers you the loan amount you need with competitive repayment terms and the best possible interest rates.

Use federal Ph.D. student loans first

If you must borrow using Ph.D. student loans, always max out federal student aid as your first funding source. Federal student loans, offered by the U.S. Department of Education, tend to be cheaper, provide more repayment flexibility, and come with other borrower perks, such as the potential for loan forgiveness.

Federal Direct Unsubsidized loans

The first federal loan option to consider is the Direct Unsubsidized loan. These loans don’t require students to demonstrate any financial need and allow for up to $20,500 in annual federal funding toward your Ph.D. program, depending on your actual educational expenses.

Key features of Direct Unsubsidized loans:

  • Students aren’t required to demonstrate financial need in order to borrow.
  • Up to $20,500 in annual loan funding is available to graduate students, though students in certain health care programs may qualify for more.
  • For graduate student borrowers, new Direct Unsubsidized loans have a fixed interest rate of 6.54% APR.

Federal Grad PLUS loans

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.

Key features of Grad PLUS loans:

  • Grad PLUS loans have a fixed interest rate of 6.28% APR for the life of the loan.
  • Certain borrowers may be eligible for forgiveness or discharge of their federal Grad PLUS loans.
  • As long as you’re enrolled at least half-time, Grad PLUS loans can cover any remaining attendance costs you may have after other financial aid is applied.

Best private Ph.D. student loans

After maxing out your federal student loans, you may still need more money to pay for your doctoral degree. If that’s the case, you’ll need to look into getting private Ph.D. 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 Ph.D. impossible.

How to get Ph.D. student loans

A graduate loan can be an important step in paying for your Ph.D. degree program. Whether you’re looking to cover tuition and fees, housing, or even miscellaneous expenses (such as a laptop for class), federal and private student loans can help.

To gain access to these loans, you must do the following.

  1. Fill out the FAFSA. The Free Application for Federal Student Aid is a form you must fill out months in advance before the deadline for each year you want financial aid. It helps determine your financial need. This is required if you are hoping to take out federal loans for any part of your educational expenses.
  2. Look into federal loans. Federal student loans have protections and features that private loans don’t offer. While you may be limited in how much you can borrow—based on things like financial need and annual limits—consider borrowing as much as you can with federal loans before turning to private loans.
  3. Shop around for a private loan. If you’ve exhausted all your other options (including scholarships, grants, educational savings, and federal loans), it may be time to turn to private loans. When looking for the right private student loan, shopping around is a wise step and can help you find the right loan with the right terms and rate.
  4. Add a cosigner. If your credit history is limited, you have a low score, or you don’t meet the income requirements for a particular lender, consider adding a creditworthy cosigner to your private loan(s). This cosigner will be held responsible for your loans until you refinance or release them, but adding them initially can often unlock lower rates and higher loan limits.
  5. Provide documentation. Before disbursing your loan, your new lender may want to see some documentation. This could include proof of employment, proof of academic progress, proof of identity, and more.
  6. Get your loan. Once approved, your loan funds will be sent directly to your school, where they’ll be applied to any outstanding balance. The difference will often be refunded to you after the start of the semester.

Alternatives to a Ph.D. student loan

If you’re looking for alternatives to Ph.D. student loans, numerous scholarships and grants are available to graduate and professional students pursuing a Ph.D.

You can also look into tuition reimbursement programs with your employer—where your employer will repay a portion of your tuition costs in exchange for an employment contract.

FAQ about Ph.D. student loans

Which Ph.D. student loan is the best?

When it comes to taking out loans for your Ph.D. program, federal student loans are usually the best place to start your search. Federal loans offer more benefits and protections than private student loans, and may even allow you to have some of your debt forgiven later on.

If you must turn to private funding, the best Ph.D. student loan for you is the one that offers approval at the lowest interest rate, with the best repayment terms for your unique situation. This lender may be different for each student borrower, so it’s wise to shop around first.

Do I need a cosigner for Ph.D. student loans?

Depending on your credit history, credit score, and current income, you may need to add a cosigner to qualify for a private Ph.D. loan. In exchange for adding a creditworthy cosigner, you may be eligible for certain loans, rates, and repayment terms you didn’t qualify for on your own. Depending on the lender, you may be able to release your cosigner from this obligation later on, once you’ve made a certain number of on-time payments.

Do Ph.D. student loans cover living expenses?

A Ph.D. loan can be taken out to cover your school-certified expenses, which may include housing. It’s important to note that some lenders (including federal student loan lenders) may have annual or aggregate limits. If you take out too much for tuition and fees, you may need to consider adding a private loan to cover your living expenses, too.

How much can I borrow with Ph.D. student loans?

The amount you can borrow with a Ph.D. student loan depends on the type of loan and even the specific lender. With federal graduate loans, you are limited to a maximum of $20,500 per year (though certain healthcare fields may qualify for higher limits). With private loans, you may be able to take out up to 100% of your eligible expenses.

When does repayment on Ph.D. student loans start?

Once you drop below half-time enrollment or graduate (depending on the lender), your grace period will usually begin. This grace period often ranges from six to nine months in length, during which you don’t need to make any Ph.D. loan payments. After that grace period, repayment will typically start.
