5 Best Ph.D. Student Loans in 2025: Federal & Private

Ph.D. student loans offer a pathway to finance the extensive costs of higher education, covering tuition and living expenses. You should first consider federal student loans from the Department of Education, followed by private student loans.

If you’ve already considered federal options, here are the best private Ph.D. loans.

Consider federal Ph.D. student loans first

If you must borrow Ph.D. student loans, consider Direct Unsubsidized Loans as your first funding source. Federal student loans from the U.S. Department of Education offer fixed interest rates, provide more repayment flexibility, and may come with the potential for loan forgiveness.

The other type of federal loan available to Ph.D. students, Grad PLUS loans, charge higher rates and a more substantial origination fee, so we recommend balancing these factors with the likelihood you’ll take advantage of federal borrower benefits once you’ve maxed out your Direct Unsubsidized Loans. Private student loans might make more sense than Grad PLUS loans for certain borrowers.

	Unsubsidized	Grad PLUS
Rates	8.08%	9.08%
Origination fee	1.057%	4.228%
Credit check required?	No	Yes
Loan amounts	Up to $20,500 per year	Up to 100% of certified costs

Federal Direct Unsubsidized loans

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

One benefit is that you don’t need a cosigner or a credit check when you apply. File the FAFSA to apply.

Federal Grad PLUS loans

The Department of Education offers Direct PLUS Loans to graduate students to cover advanced education. If you’re eligible, you could borrow up to the school-certified cost of attendance minus any grants or scholarships.

Unlike some federal loans, Grad PLUS Loans aren’t available to you if you have an adverse credit history, and you’ll undergo a credit check to prove you don’t.

Best private Ph.D. student loans

If you need funds to pay for your doctoral degree, private Ph.D. student loans might make sense in addition to or instead of federal loans.

Private student loans can be harder to qualify for and may have less flexible repayment plans. Our team spent hours evaluating the options to choose the best Ph.D. student loans. Among other factors, we considered their options for deferment, repayment plans, cosigner policies, and grace periods.

Best Graduate Student Loans

How are Ph.D. student loans different from graduate student loans?

Ph.D. student loans tend to be the same as other graduate student loans.

When determining which loan to borrow, look for one with a competitive interest rate, flexible repayment terms, and low or no fees. Review your options for when repayment starts. Can you make immediate, interest-only, or deferred payments while in school and for several months after you graduate or start a postdoctoral research or internship program?

How much does taking out a student loan for a Ph.D. cost?

Most private student loans for Ph.D. programs don’t include an application or origination fee, but you must pay interest charges. Interest starts accruing on your loan balance from the date of disbursement. The higher your rate, the more you’ll pay in interest over time.

Let’s say, for example, you take out a Ph.D. student loan for $50,000 with a 7% interest rate. Over 10 years of repayment, you’d pay $19,665 in total interest charges. If your rate were higher, at 10%, your total interest charges over 10 years would be $29,290.

When taking out a private student loan, your or your cosigner’s credit score has a major impact on the rate you get. Borrowers with the best credit may qualify for a lender’s lowest rates, while those with weaker credit could pay a higher interest rate.

If you can boost your credit score or apply with a creditworthy cosigner, you’ll improve your chances of getting a competitive interest rate on your Ph.D. student loan.

Is a Ph.D. student loan right for you?

A Ph.D. student loan may be right for you if you need funding for school. Before borrowing a private student loan, it’s smart to consider the following:

Pursue gift aid you don’t need to pay back, such as grants and scholarships
Max out your eligibility for federal Direct Unsubsidized Loans, which come with benefits including income-driven repayment and potential eligibility for loan forgiveness
Work part-time to minimize the amount you must borrow in loans

If you still have a gap in funding, consider a federal Grad PLUS loan or a private Ph.D. student loan. Federal PLUS loans offer more repayment options and protections, but private loans may give creditworthy borrowers better rates and lower costs.

In July 2024, Grad PLUS loans had a fixed rate of 9.08% and loan fees of 4.228%, for example, whereas some private lenders offered rates starting around 4% and don’t charge origination fees. Compare both options to see which loan type would have a lower cost of borrowing for you.

How to get a student loan for a Ph.D. program

A graduate loan can be crucial in paying for your Ph.D. program. Whether you’re looking to cover tuition and fees, housing, or miscellaneous expenses, federal and private student loans can help.

Our expert’s take on loans for Ph.D. students

Erin Kinkade

CFP®

The student loans needed for a Ph.D. program will likely be more than a bachelor’s or master’s degree. But along with that, the earning potential could be greater and facilitate an easier repayment. It’s important to understand the repayment terms; try to make extra payments while pursuing the Ph.D., and don’t wait until you graduate or get a job, if possible. Of course, make room in your budget for this payment, and when job searching, ask whether the employer offers any benefits for paying back student loans, such as 401(K) employer plan matching. This will assist with “lost” retirement savings and help you gain traction to meet your retirement goals.

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

Fill out the FAFSA. The Free Application for Federal Student Aid is a form you must fill out months before the deadline for each year you want financial aid. It helps determine your financial need and is required if you hope to take out federal loans for any part of your educational expenses.
Consider federal loans. Federal student loans have protections and features private loans don’t offer. While you may be limited in how much you can borrow based on financial need and annual limits, consider borrowing as much as you can with Direct Unsubsidized Loans before turning to Grad PLUS or private loans.
Shop around for a private loan. Shopping around is a wise step when looking for the right private student loan, and it can help you find the right loan with the right terms and rates.
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 loans. This cosigner is equally responsible for your loans until you refinance or release them, but adding them when you apply can often unlock lower rates and higher loan limits.
Provide documentation. Before disbursing your loan, your new lender may want to see documentation. This could include proof of employment, academic progress, or identity.
Get your loan. Once approved, your loan funds are sent to your school and applied to any outstanding balance. Your school should refund the difference 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, consider these funding options that could help lower the cost of attendance.

Tuition reimbursement

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.

Program support

Some Ph.D. programs offer financial support, which can be structured in several ways. The first is a fully funded Ph.D. program, which covers tuition, fees, and a stipend for living expenses.

You can also search for Ph.D. fellowship programs. These programs offer financial help during your studies based on merit, and a service requirement may be attached to the funding.

FAQ

Which Ph.D. student loan is the best?

Federal student loans are often the best place to start your search. Federal loans offer more benefits and protections than private student loans. They may even allow you to have some of your debt forgiven later, particularly if you plan to work in public service.

If you consider 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 might 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.

Depending on the lender, you could release your cosigner from this obligation after a certain number of on-time payments.

Do Ph.D. student loans cover living expenses?

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

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. Federal graduate loans limit you to a maximum of $20,500 per year (though certain healthcare fields may qualify for higher limits). With private loans, you might be able to take out up to 100% of your eligible expenses.

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

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