Private Student Loans: What to Know Before You Borrow (Federal First)

By Student Relief Solutions Editorial — Reviewed by Marcus Whitfield

Private student loans fill a real gap for some borrowers — but they should be the last stop on a funding checklist, not the first call you make. Before you sign with a private lender, you need to know exactly what federal aid you're leaving on the table.

The short version

Federal student loans — Direct Subsidized, Direct Unsubsidized, and PLUS — are almost always the better first option: fixed rates, income-driven repayment, deferment rights, and forgiveness eligibility. Private loans offer none of these protections by default. If you've exhausted your federal borrowing limits, are an international student ineligible for federal aid, or are in a graduate/professional program where the federal limits don't cover your costs, private loans may be unavoidable. If you haven't, stop here and file the FAFSA first.

Federal aid: exhaust this before anything else

Per studentaid.gov, dependent undergraduate students can borrow up to $31,000 in federal Direct Loans over their academic career ($23,000 subsidized). Independent undergraduates can borrow up to $57,500 ($23,000 subsidized). Graduate students can borrow up to $138,500 in Direct Loans (including undergraduate debt). Graduate and professional students may also access Direct PLUS Loans for the gap between the cost of attendance and other aid, with no hard aggregate cap beyond the cost of attendance. Parents of undergraduates can access Parent PLUS Loans similarly.

Before considering private loans, check whether you've:

• Filed the FAFSA for the current aid year at studentaid.gov
• Accepted all available federal grant aid (Pell Grant, SEOG, state grants — these don't need to be repaid)
• Accepted federal work-study if offered
• Accepted your full federal loan eligibility, including unsubsidized loans
• Explored institutional scholarships and emergency aid from your school's financial aid office
• If a graduate or professional student: determined whether PLUS Loans cover your remaining gap

If after all of the above you still have a funding gap, private loans may be the appropriate next step.

What private student loans are and aren't

Private student loans are issued by banks, credit unions, and specialized online lenders. They are governed by your lender contract, not federal statute. Key differences from federal loans:

• Interest rates: Variable or fixed, set by the lender based on creditworthiness. As of 2026, private undergraduate loan rates range roughly from 4% to 16% APR depending on credit score and cosigner status (per lender-published rates at SoFi, Earnest, College Ave, and Sallie Mae — verify directly with each lender as rates change frequently). Federal Direct Unsubsidized rates for undergraduates are fixed at 6.53% for the 2024–2025 year per studentaid.gov.
• Repayment flexibility: Private lenders typically offer standard repayment, interest-only in school, and deferred payment options. They do not offer income-driven repayment. If your income drops after graduation, the private lender's forbearance (typically 12 months total over the life of the loan) is the only relief available — and it is a courtesy, not a right.
• Deferment: Federal loans have statutory deferment for unemployment, economic hardship, military service, and more. Private lenders offer in-school deferment almost universally, but post-graduation hardship deferment varies widely by lender.
• Forgiveness eligibility: Private loans are never eligible for PSLF, Teacher Loan Forgiveness, IDR forgiveness, closed school discharge, or borrower defense. These are federal programs for federal loans only.
• Cosigner risk: Most students without established credit will need a cosigner, typically a parent or guardian. If you default or die (and the lender does not discharge on death), the cosigner is fully liable. Cosigner release is offered by most major private lenders after 12–48 months of on-time payments and creditworthiness review — but it is not guaranteed and varies by lender.

Interest rates: fixed vs variable

Private lenders offer both fixed and variable rate options. Fixed rates don't change over the life of the loan. Variable rates are tied to a benchmark index (typically SOFR, the Secured Overnight Financing Rate) and can rise or fall monthly or quarterly. A variable rate that starts lower than a fixed rate can exceed it if benchmark rates rise. Given that private loans for education typically carry 10–15 year terms, a variable rate is a significant bet on interest rate movements you can't control. For borrowers who plan to pay off the loan aggressively in 3–5 years, variable rates may make mathematical sense. For borrowers who will carry the balance longer, the predictability of a fixed rate is generally worth the premium.

Cosigner considerations

Most undergraduate students lack the credit history to qualify for a competitive private loan rate without a cosigner. A cosigner with strong credit (typically 700+) can substantially reduce the rate offered. Before signing with a cosigner:

• Confirm whether the lender offers cosigner release, and under what conditions (typically 12–48 consecutive on-time payments plus income and credit review)
• Check whether the lender discharges the loan upon the student borrower's death or total disability, or whether the cosigner remains liable
• Have a direct conversation with your cosigner about what they're taking on — cosigning a student loan is a multi-year financial commitment that affects their debt-to-income ratio and credit

What to compare across private lenders

Not all private student loan products are equal. When comparing lenders, focus on:

• APR (not just interest rate): The APR includes fees. Origination fees, while uncommon in the current private student loan market, do exist at some lenders and increase the true cost.
• Grace period: How long after graduation before payments begin? Most federal loans offer a 6-month grace period. Private lenders vary from 6 months to immediate repayment.
• Forbearance terms: What hardship forbearance does the lender offer post-graduation? Maximum months, qualifying conditions, interest treatment during forbearance.
• Death and disability discharge: Some private lenders do discharge on borrower death or permanent disability. Others do not. This is in the loan agreement, and you should read it.
• Cosigner release: If you need a cosigner, confirm the release pathway before you borrow.
• In-school repayment options: Making interest-only or full payments while in school significantly reduces total interest paid. Not all borrowers can do this, but if you have part-time income, it's worth calculating the long-term savings.

When private loans are the honest answer

After exhausting federal aid, you may find you have a real funding gap. In that situation, here are the profiles where private loans are the least-bad option:

• Graduate and professional students at high-cost programs (medicine, law, MBA) who have maxed federal PLUS loan eligibility and have a clear post-graduation income trajectory to service private debt
• International students ineligible for federal aid who have a U.S.-based cosigner and verified income post-graduation
• Borrowers with strong credit (or a cosigner with strong credit) who qualify for a private rate significantly below the federal unsubsidized rate and who are certain they will not need IDR or PSLF

When private loans are the wrong answer

Private loans are wrong for most borrowers in these situations:

• You work in public service, education, healthcare, or government — even if you don't know you'll stay there 10 years, private loans eliminate the PSLF option permanently
• You have unstable income or a career path with variable earnings — the lack of IDR means no payment protection if income falls
• You haven't exhausted federal borrowing limits — the federal options have protections that private loans don't replicate
• Your cosigner can't truly afford to cover the loan if you can't pay — don't put someone else in that position

The part most people miss: repayment flexibility is the real price

When students and parents compare private vs. federal loans, they usually compare interest rates. That's the wrong comparison axis. The real cost difference is repayment flexibility. A federal loan at 6.5% that you can dial down to $50/month if you lose your job is categorically different from a private loan at 5.0% where your $800 payment is required regardless of your income. The 1.5% rate savings can easily be offset by the cost of missing payments when life doesn't go as planned. The federal safety net is worth more to most borrowers than the rate difference.
