Understanding Student Loan Refinancing: Is It Worth It?

Whether refinancing is worth it depends on two separate questions: how much a new rate and term change the cost of the loan, and which federal protections the borrower would give up. The first can be calculated. The second depends on circumstances, and for federal loans the switch is permanent.

Key takeaways

In a refinance, a private lender pays off existing loans with a new private loan. The CFPB says moving federal loans into a private loan "can't be reversed."
A federal Direct Consolidation Loan keeps the loans federal but cannot lower the rate, and one made on or after July 1, 2026 can be repaid only under the new standard plan or the Repayment Assistance Plan.
In the worked example, $50,000 at 7.0% over 10 years costs $19,665.09 in interest. At 5.5% over 10 years it costs $15,115.77. At 5.5% over 15 years it costs $23,537.51, even though the monthly payment falls by $172.00.
Refinancing private loans can also cost a protection: the federal rule releasing a co-signer when the student borrower dies may not reach a loan that consolidates earlier private loans, because the law's definition of co-signer excludes such loans.

What refinancing is and is not

In a private refinance, a lender pays off one or more existing student loans and issues a new loan with its own rate, term and conditions. The loans being paid off can be federal, private or both. The CFPB's guidance on consolidating or refinancing student loans warns that moving federal loans into a private loan means losing the federal loan's benefits and protections, and that "this type of consolidation can't be reversed."

A federal Direct Consolidation Loan is not a refinance in that sense, because the loan stays in the federal program. For consolidation applications received on or after July 1, 2013, the fixed rate is the weighted average of the rates on the loans being consolidated, "rounded to the nearest higher one-eighth of one percent" (20 U.S.C. 1087e(b)(8)(D)). Consolidation can simplify payments, but it cannot reduce the rate. Under section 82001(e) of Public Law 119-21, a Direct Consolidation Loan offered on or after July 1, 2026 may be repaid only under the new standard plan or the Repayment Assistance Plan, both described below.

Feature	Private refinance	Federal Direct Consolidation
Who sets the rate	The lender, based mainly on credit history or score, per the CFPB	Weighted average of the old rates, rounded up to the nearest 1/8 of 1%
Loan stays federal	No, and for federal loans the switch can't be reversed, per the CFPB	Yes
Public Service Loan Forgiveness	CFPB: no longer eligible	An eligible loan type under 34 CFR 685.219

The last row comes from the federal regulation on Public Service Loan Forgiveness (34 CFR 685.219). Being an eligible loan is not enough on its own: the borrower must also repay under a qualifying plan and meet the employment requirements.

What federal borrowers give up

When federal loans go into a private loan, the CFPB lists four losses:

the borrower's rights under the federal student loan program, including deferment, forbearance, cancellation and income-driven repayment;
eligibility for federal loan forgiveness programs;
possibly, discharge or forgiveness on death or permanent disability;
for active-duty servicemembers, possibly a Servicemembers Civil Relief Act interest-rate reduction on loans taken out before service.

The CFPB's page on private student loans adds that they "generally do not feature the flexible repayment terms or borrower protections offered by federal student loans."

Death and disability

The CFPB's page on student loans after death or disability says federal loans do not pass to anyone else when the borrower dies: a relative can notify the servicer and the loan is canceled. Federal loans can also be discharged for total and permanent disability, followed by a three-year monitoring period.

Private loans are different. The same page says private lenders are not legally required to cancel loans on death or disability, although some have special discharge provisions, and that the debt may pass to a spouse or co-signer. The loan agreement is the place to check.

Federal rules changing in 2026

What a borrower would leave behind is itself changing. The points below come from the enacted text of sections 81001 and 82001 of Public Law 119-21, the 2025 reconciliation law.

Repayment plans

Repayment Assistance Plan (RAP): an income-based plan the Department of Education must offer from July 1, 2026. The remaining balance is canceled after 360 qualifying monthly payments, provided the borrower's most recent payment before cancellation was made under RAP. Some deferment months also count.
Borrowers with a loan made on or after July 1, 2026: two plans are available, RAP or a new standard plan, and the choice applies to all of the borrower's Direct loans, including older ones. A borrower who does not choose is placed on the standard plan, and can switch between the two at any time. Parent PLUS loans made on behalf of a dependent student cannot be repaid under RAP.
Borrowers whose loans were all made before July 1, 2026: the earlier repayment plans still apply, and RAP is added as an option, again except for Parent PLUS loans made on behalf of a dependent student. The law repeals income-contingent plans effective July 1, 2028. Borrowers in those plans must choose another plan before then, and anyone who doesn't is placed in RAP or, for loans RAP cannot take, income-based repayment.

Under the new standard plan, the repayment period depends on the borrower's total outstanding Direct Loan principal when entering repayment:

Total outstanding principal	Standard plan period
Less than $25,000	10 years
$25,000 to under $50,000	15 years
$50,000 to under $100,000	20 years
$100,000 or more	25 years

34 CFR 685.219 lists RAP as a qualifying repayment plan for Public Service Loan Forgiveness. A borrower pursuing that program keeps access to it only while the loans stay federal.

Rates and borrowing limits

The Department of Education's announcement on 2026-27 Direct Loan rates sets fixed rates for loans first disbursed from July 1, 2026 through June 30, 2027:

6.52% for undergraduate Direct Subsidized and Unsubsidized Loans;
8.07% for graduate and professional Direct Unsubsidized Loans;
9.07% for Direct PLUS Loans.

Each rate is fixed for the life of the loan. Public Law 119-21 also ends Direct PLUS Loans for graduate and professional students from July 1, 2026 and caps federal borrowing (figures in the FAQ).

Private loan terms and taxes

Rates, credit and variable rates

The CFPB says private rates and fees depend mainly on credit history or score, and a co-signer may bring a better rate but becomes liable if the borrower does not pay. It warns that a variable refinance rate could rise above the original fixed rate, and that the lowest refinance rates tend to come with shorter terms.

Co-signer release on death

Section 601 of Public Law 115-174, enacted May 24, 2018, amended the Truth in Lending Act with two protections:

When the holder of a private education loan is notified that the student borrower has died, it must release any co-signer within a reasonable timeframe.
The creditor may not declare a default or accelerate the loan solely because a co-signer died or went bankrupt.

These rules apply to agreements entered into on or after November 20, 2018. The law's definition of co-signer, however, excludes "an obligation under a private education loan extended to consolidate a consumer's pre-existing private education loans." A co-signed refinance of private loans may therefore fall outside these protections, even when the original loans had them.

Taxes

The student loan interest deduction is the smaller of $2,500 or the interest paid in the year, per IRS Topic 456. To claim it, the borrower must:

be legally obligated to pay the interest on a loan taken out solely for qualified higher education expenses;
not file as married filing separately;
not be claimed as someone else's dependent.

For tax year 2026, Rev. Proc. 2025-32 phases the deduction out between $85,000 and $100,000 of modified adjusted gross income, or $175,000 to $205,000 on a joint return. The joint range was $170,000 to $200,000 for 2025, per IRS Publication 970, which also covers refinanced loans (see the FAQ).

A worked example: rate versus term

Illustrative example, not a real offer: a borrower owes $50,000 at 7.0% with 10 years left, and compares three options: keeping the loan, refinancing to 5.5% over 10 years, or refinancing to 5.5% over 15 years. The monthly payment on a fixed-rate loan comes from the standard amortization formula:

payment = P × i / (1 − (1 + i)^−n)

P = loan balance ($50,000)
i = monthly rate (annual rate ÷ 12)
n = number of monthly payments (years × 12)

Option	Monthly payment	Total interest	Interest vs. keeping the loan
7.0%, 10 years (keep)	$580.54	$19,665.09	baseline
5.5%, 10 years	$542.63	$15,115.77	$4,549.32 less
5.5%, 15 years	$408.54	$23,537.51	$3,872.42 more

A lower rate over the same term saves $4,549.32 in interest and cuts the payment by $37.91 a month. Stretching the term to 15 years cuts the payment by $172.00 a month, but total interest rises by $3,872.42 compared with keeping the original loan, despite the lower rate. That matches the CFPB's point that a longer repayment period means smaller payments but more interest over the life of the loan.

Break-even views

Rate needed over 15 years: a 15-year loan on $50,000 matches the original loan's total interest only at a rate of about 4.68%, so 5.5% falls short.
Keeping the old payment: a borrower who refinances to 5.5% and keeps paying $580.54 a month clears the balance in about 110 months instead of 120.

The example ignores fees, which would reduce the savings. The loan calculator can run other balances, rates and terms. If federal loans are involved, the dollar savings have to be weighed against the protections described above, which this table can't price.

When refinancing may or may not fit

Where the trade-off can look favorable

The loans are already private, so no federal protection is lost, and the new loan's death, disability and co-signer terms are no weaker than the old ones.
The new rate is lower, the term is the same or shorter, and a calculation like the one above shows lower total interest.
The borrower does not expect to use income-based repayment, forgiveness or federal deferment, and has other resources if income falls.
The borrower's or co-signer's credit has improved since the original loan.

Where more caution applies

The loans are federal and the borrower is pursuing Public Service Loan Forgiveness or may need an income-based plan.
The offer has a variable rate.
The lower payment comes from a longer term.
The household depends on the borrower's income, and the lender's death, disability and hardship terms are unknown or weak.

Frequently asked questions

Does a Direct Consolidation Loan lower the interest rate?

No. The rate is the weighted average of the consolidated loans' rates, rounded up to the nearest one-eighth of one percent. As an illustration, $20,000 at 4.0% and $30,000 at 6.0% average 5.2%, so the consolidation rate would be 5.25%.

Does consolidating federal loans keep Public Service Loan Forgiveness available?

Yes, as far as the loan type goes: the regulation lists a Direct Consolidation Loan as eligible. The borrower must still repay under a qualifying plan and work full time, generally at least 30 hours a week on average, for a qualifying employer. Federal loans refinanced into a private loan are no longer eligible, according to the CFPB.

Can interest on a refinanced student loan still be deducted?

Publication 970 counts interest on a loan used solely to refinance a qualified student loan of the same borrower, if the other conditions are met. If the new loan is larger than the old one and the extra goes to non-education costs, none of its interest is deductible.

What happens to a co-signer if the student borrower dies?

It depends on when and how the loan was made. Release on death is required by law only for private agreements entered into on or after November 20, 2018, and the law's definition of co-signer excludes loans that consolidate earlier private loans. Otherwise the contract governs, and the CFPB notes the debt may pass to a co-signer.

What are the new federal borrowing limits for graduate students?

For periods of instruction beginning on or after July 1, 2026, Public Law 119-21 caps Direct Unsubsidized Loans at $20,500 a year for graduate students and $50,000 a year for professional students. The aggregate limits, on top of undergraduate borrowing, are $100,000 and $200,000. Parent PLUS Loans are capped at $20,000 a year and $65,000 in total per dependent student. Students who were enrolled and had a loan for their program as of June 30, 2026 keep the prior limits for the lesser of three academic years or the rest of the program.

A checklist before applying

List every loan with its type (federal or private), balance, rate and servicer, and note which federal programs the borrower uses or may need.
Get offers in writing and note whether the rate is fixed or variable, how a variable rate can change, the term, and any fees.
Compare each offer with the current loan on total interest as well as the monthly payment.
Read the new lender's terms on death, disability, hardship and co-signer release, and compare them with the current loan's.
If federal loans are involved, check on the federal student aid site how the change affects repayment plan options. The step cannot be reversed.
