Comparison Criteria: Interest Rates, Fees, Repayment Flexibility, and Protections
When you compare student loans, focus on the factors that affect both your short-term cash flow and your long-term financial health. Interest rates, fees, repayment flexibility, and borrower protections are the most important criteria to evaluate.
Federal student loans have fixed interest rates and charge origination fees, while private student loans may offer fixed or variable rates, often with no origination fees. But the real difference lies in repayment options and protections. Federal loans provide income-driven repayment plans, loan forgiveness programs, deferment and forbearance options, and death or disability discharges. Private loans typically lack these safeguards.
A useful approach is to compare loans with the same repayment term and amount to see the total cost, including interest. Also consider whether you can afford payments while in school, because some private loans require immediate repayment.

Federal Student Loan Comparison: Direct Subsidized, Unsubsidized, PLUS
The federal government offers several types of Direct Loans, each with its own terms. For the 2026-27 academic year, the Direct Subsidized and Unsubsidized Loans for undergraduates carry a fixed interest rate of 6.52%, while the Parent PLUS Loan rate is 9.07%. Origination fees also differ: 1.057% for Direct Subsidized and Unsubsidized Loans, and 4.228% for PLUS Loans.
Subsidized loans are available to undergraduate students who demonstrate financial need. The government pays the interest while you are in school and during other periods, making them the most affordable option. Unsubsidized loans accrue interest from the moment they are disbursed, but you are not required to make payments while in school. PLUS loans are for parents of dependent undergraduates and require a credit check, but not a cosigner.
No federal undergraduate loan requires a credit check or a cosigner. Borrowers should maximize their federal loan eligibility before considering private loans, because federal loans offer far more robust repayment and forgiveness benefits.

Private Student Loan Offerings: Variable and Fixed Rates
Private student loans are offered by banks, credit unions, state-based lenders, and online lenders. Unlike the federal government, private lenders charge interest rates based on your creditworthiness—and your cosigner’s, if you have one. Rates can be fixed or variable.
Most private lenders do not charge origination fees, but they may impose late payment fees, collection costs, and other charges. They also typically require a credit check and often require a cosigner for students without an established credit history. Some private lenders offer deferment or forbearance options, but these vary and are generally more limited than federal provisions.
Because private loan terms vary by lender and can change, it is important to compare offers from multiple lenders. Some lenders allow you to prequalify to see potential rates without affecting your credit score, but availability varies.
- Interest rate can be fixed or variable, depending on your credit profile
- No origination fee with many lenders, but other fees may apply
- Credit check is required, and a cosigner may be necessary
- Repayment may begin while you are still in school
- Protections such as deferment and forbearance are limited and vary by provider

How Loan Features Differ by Borrower Profile
Your financial situation and academic level affect which loan is best for you. Federal loans are available to both undergraduate and graduate students, but graduate and professional students are not eligible for subsidized loans. They can, however, take out Direct Unsubsidized Loans and, in some cases, Grad PLUS Loans.
For undergraduates, the key distinction is between subsidized and unsubsidized loans. If you qualify for a subsidized loan, it is usually the cheapest because the government covers the interest while you are in school. Independent students may have higher annual borrowing limits, but all federal loans have caps that may not cover the full cost of attendance.
Private loans may be necessary if you have exhausted your federal eligibility or are a parent who wants to help a dependent student. However, private loans require a credit check, and if you have no or low credit, you will likely need a cosigner to qualify for a loan or to get a lower rate.

Using the Comparison to Shortlist Your Options
Start by borrowing the maximum federal aid for which you qualify. Federal loans come with built-in protections such as income-driven repayment, loan forgiveness, and deferment options that private loans do not match. If you still need additional funding, use private lenders as a supplement.
When comparing private loan offers, use the same loan amount and repayment term to see how monthly payments and total interest costs differ. A longer repayment term reduces monthly payments but significantly increases the total cost because interest accrues over more years.
Create a side-by-side comparison of at least three lenders, including the interest rate (fixed or variable), fees, repayment options, and any borrower benefits such as auto-pay discounts or death/disability discharges. Some private lenders offer these protections, but they are not universal.
- List your total cost of attendance and subtract all grants, scholarships, and federal loan eligibility.
- For the remaining gap, compare private loan offers from multiple lenders.
- Consider the total cost over the life of the loan, not just the monthly payment.
- Look for features that match your needs, such as in-school repayment deferment, cosigner release, or death and disability discharge.

Making a Final Choice: Checklist and Considerations
Before you sign any loan agreement, run through this checklist to ensure you are making an informed decision. If a feature is not listed in the loan contract, do not assume it is offered.
Federal loans should always be your first choice because they offer the most comprehensive protections. If you need a private loan, only borrow what you truly need and exhaust all other aid first.
Remember that borrowing is a long-term commitment. The total cost of a private loan depends on the principal, interest rate, and repayment term.
- Maximize federal student loans before considering private loans.
- Check whether the loan has a fixed or variable rate and whether the rate is competitive.
- Review all fees, including origination fees, late fees, and any charges for prepayment.
- Confirm that the repayment plan fits your budget, and ask about deferment or forbearance options.
- Understand the loan's discharge provisions in the event of death or disability.
- If you need a cosigner, compare how different lenders treat cosigner release.

Where to Find Current Rate and Fee Information
Federal student loan interest rates and fees are set each academic year and are published by the U.S. Department of Education. Rates for the 2026-27 academic year are current as of the publication of this guide, but they will change for future years.
For private loans, rates and fees vary by lender and your credit profile. Many lenders publish their range of rates, but the rate you receive will depend on your credit history and, if applicable, your cosigner. Contact individual lenders or use their websites to obtain personalized rate quotes.
When comparing private offers, always check the Annual Percentage Rate (APR), which includes the interest rate plus certain fees, so you can see the true cost of the loan. Also review the terms for repayment, deferment, and any borrower benefits.

Frequently asked questions
How do federal and private loan rates compare?
Federal undergraduate loans have fixed rates, currently 6.52% for the 2026-27 academic year, while private loan rates vary based on your creditworthiness and can be fixed or variable. Private rates may be higher than federal rates. Parent PLUS loans have a higher fixed rate of 9.07%.
Sources: University of Illinois at Urbana-Champaign Office of Student Financial Aid, Dickinson CollegeWhat features are most important to compare?
Focus on interest rates (fixed vs. variable), origination fees, credit and cosigner requirements, repayment flexibility (including deferment and forbearance), and protections such as forgiveness, death, and disability discharges. These factors have a major impact on your total cost and financial safety net.
Sources: University of Illinois at Urbana-Champaign Office of Student Financial Aid, Dickinson CollegeDo federal loans offer better repayment options than private ones?
Yes. Federal loans offer income-driven repayment plans and loan forgiveness programs, and they also provide deferment and forbearance options that private lenders typically do not match. Private loans may offer limited deferment or forbearance, but these are usually less generous and vary by lender.
Sources: University of Illinois at Urbana-Champaign Office of Student Financial Aid, Student Loan Borrower Assistance (National Consumer Law Center), ISL Education LendingCan I compare loans without affecting my credit score?
Some private lenders offer prequalification, which allows you to check potential rates without a hard credit inquiry, so your credit score is not affected. However, prequalification may not be available from all lenders.
Sources: LendKeyWhat is the best loan for someone with no or low credit?
Federal undergraduate student loans are the best option because they do not require a credit check or a cosigner. However, if you are a parent applying for a Parent PLUS loan, a credit check is required, and adverse credit history could affect eligibility. Private loans almost always require a credit check, so borrowers with no or low credit will likely need a cosigner to qualify or obtain a more favorable rate.
