Student loan refinancing replaces existing loans with a new private loan; federal income-driven repayment (IDR) keeps eligible federal loans in the federal system and sets payments under a federal plan’s rules. Refinancing may lower your rate or monthly payment, but refinancing federal debt gives up federal repayment and forgiveness protections. Compare an actual refinance offer with the federal plans you are eligible for—not just by monthly payment, but by APR, rate type, term, total expected repayment, and the value of protections you would surrender.
This is general U.S. information, not a borrower-specific calculation. The right choice depends on your loan types and disbursement dates, income and family circumstances, forgiveness eligibility, and the terms a private lender actually offers.

What is the difference between student loan refinancing and federal IDR?
The main difference is whether your debt stays under federal loan rules. IDR is a way to repay eligible federal loans; refinancing pays off existing loans with a new private loan governed by the new lender’s contract.
Under IDR, a federal plan calculates payments using income and household or dependent information according to its own formula. If the borrower meets the applicable requirements and completes the required repayment period, some plans may discharge a remaining balance. Plan access depends partly on the type of loan and when it was first disbursed. Check eligibility rather than assuming a plan is available because you have federal loans.

With private refinancing, a lender underwrites a new loan and offers its own rate and repayment term. The new loan may have a fixed or variable rate. Refinancing can lower the interest rate, or lower the monthly payment by stretching repayment over more time; those are different outcomes. The Consumer Financial Protection Bureau (CFPB) explains that a longer term can increase the total cost even when the payment falls.
Private underwriting generally considers credit history and other information used by the lender. The rate shown in an advertisement is not necessarily the rate you will receive. Compare the written offer, including its APR, rate type, term, payment, fees and conditions.
Do not confuse refinancing with federal consolidation. This comparison is about replacing loans with a private loan, not combining federal loans within the federal system. A private refinance of federal loans transfers that debt out of the federal program structure.
Which federal IDR plans and rules should I check in 2026?
Federal Student Aid’s current guidance lists several plan calculations, but a plan’s formula alone does not establish that you qualify. Verify the eligible plans for your loans and circumstances through your StudentAid.gov account and the agency’s current IDR FAQs.
| Plan | Federal Student Aid’s current description | Repayment period | Important qualification |
|---|---|---|---|
| RAP | 1%–10% of adjusted gross income (AGI), divided by 12; subtract $50 per dependent claimed on the federal tax return, with a $10 minimum monthly payment. | 30 years | Listed for most eligible Direct Loans disbursed before or after July 1, 2026. Direct parent PLUS loans are excluded. |
| IBR | 15% of discretionary income, or 10% for new borrowers. | 25 years, or 20 years for new borrowers | Eligibility depends on loan and borrower rules. |
| ICR | The lesser of 20% of discretionary income or an income-adjusted payment based on a 12-year fixed plan. | 25 years | ICR ends no later than July 1, 2028. |
| PAYE | 10% of discretionary income, subject to a payment cap and eligibility criteria. | 20 years | PAYE ends no later than July 1, 2028. |
Prices checked November 2026.
These are descriptions of plan formulas and periods, not estimates of your payment or promise of forgiveness. Federal Student Aid says eligible loans disbursed before July 1, 2026 may be able to use IBR, ICR, or PAYE subject to plan-specific rules; RAP is listed for most eligible Direct Loans before or after that date. Loan type and first disbursement date can change the answer, so use the agency’s current eligibility guidance rather than extrapolating from this table.
The plan period is not automatically the time every borrower will make payments. Income, family size, annual recertification, qualifying payments and any applicable discharge rules affect the result. A projected ending balance is also not the same as a guaranteed forgiveness amount. Save the calculator assumptions and review them when your income or household changes.
There is also a time-sensitive issue for borrowers in SAVE: Federal Student Aid says SAVE is no longer available and directs affected borrowers to select another eligible plan. Its SAVE transition guidance says a borrower who does not choose another plan by the servicer’s final 30-day deadline may be enrolled in a standard plan based on loan timing. Review your account and servicer notice for your deadline and options; transition details can change.

How do I compare the actual cost of IDR and refinancing?
Compare a borrower-specific federal estimate with the terms of an actual private offer. A monthly payment by itself cannot tell you which choice costs less over time or which safeguards matter more.
- Identify each loan. Sign in to StudentAid.gov and record each federal loan’s type, balance, interest rate, current plan, and recertification date. Check private loans separately; federal IDR applies only to eligible federal loans.
- Estimate eligible federal options. Use Federal Student Aid’s repayment calculator or Loan Simulator to compare plans available to you. The tools can show estimated payments, total paid, interest paid, ending balance, and term date.
- Check forgiveness or discharge plans before shopping. If you may qualify for Public Service Loan Forgiveness (PSLF), teacher loan forgiveness, disability discharge, borrower-defense discharge, or another federal route, consider what refinancing would remove before weighing a rate offer.
- Get and examine refinance offers. Compare APR, fixed or variable rate, monthly payment, repayment term, total expected repayment, and any disclosed fees or conditions. Use the lender’s actual offer rather than an advertised starting rate.
- Put the differences side by side. Compare the federal estimates with the private offer’s payment and total repayment, then consider payment stability, term, and protections separately. If a term is longer, ask how much the lower payment adds to total repayment.
For an apples-to-apples review, write down the assumptions behind each figure. A federal estimate may show a payment that changes as income or family information changes, while a private offer may show a scheduled payment for a chosen term. A fixed private rate offers more payment predictability than a variable rate, but the relevant question is still the complete APR and repayment schedule. A shorter private term may reduce total interest while increasing the required monthly payment.
Do not compare only the first month’s bill. Ask how many scheduled payments remain, the total dollars expected to be paid, whether the rate can change, and whether any fee or condition affects the quoted figure. If your objective is immediate affordability, a lower payment may help; if your objective is minimizing total repayment, a longer term may work against you. These are separate decisions.

Borrowers can consent to retrieval of federal tax information or submit income documentation. Federal loan servicers also provide help for free, so paying a third party is not required to apply for a federal repayment plan.
The CFPB’s guidance describes the key refinance trade-off: a private lender may lower the rate or payment, but a lower payment achieved by extending the term can raise overall cost. For a fair comparison, use the same time horizon and be clear about whether you are comparing monthly affordability, total dollars repaid, or both. Those questions can point to different choices.
What federal benefits can I lose by refinancing federal loans?
Private refinancing of federal loans generally removes access to federal repayment and forgiveness programs for the refinanced debt. Federal Student Aid identifies income-based repayment, qualifying federal deferment and forbearance, and federal forgiveness or discharge programs among the benefits that may be lost.
That can matter if your income falls, you face a hardship, or your work may qualify you for forgiveness. Federal PSLF can forgive a remaining balance after 120 qualifying payments while working for a qualifying public-service employer and meeting program requirements. The CFPB also describes possible teacher-loan forgiveness after five years at qualifying low-income schools. These are conditional pathways, not guarantees for every borrower.

Discharge protections can also be significant. Federal guidance identifies total and permanent disability discharge and borrower-defense discharge as examples of federal programs that may no longer apply after a private refinance. A private lender may offer its own hardship, death or disability, deferment, forbearance or discharge provisions, but those terms are controlled by the private contract and are not interchangeable with federal programs.
Some private lenders may offer their own hardship relief or discharge terms, but those are lender-specific and are not the federal programs. Read the new loan contract to understand what relief it offers and under what conditions. The CFPB states: “If you refinance your federal loan with a new private student loan, you will no longer be eligible to participate in these federal loan forgiveness programs.” See the agency’s refinancing guidance and Federal Student Aid’s Direct Loan Exit Counseling Guide.
Federal-to-private refinancing cannot be reversed according to CFPB guidance. That makes the decision more than a rate comparison: once federal loans are paid off by a private refinance, you cannot simply return that debt to federal IDR or federal forgiveness programs. The CFPB has also reported concerns about refinance marketing that suggested borrowers might retain federal forgiveness eligibility. Do not assume federal eligibility survives unless an official program rule confirms it; a private lender’s own benefit is not the same thing.
When might refinancing make sense—and when is IDR a better fit?
Refinancing may be worth evaluating if a borrower has a specific offer with a favorable rate and term and is comfortable with the protections attached to the new private loan. For federal loans, that means being prepared to give up federal IDR and the federal deferment, forbearance, forgiveness, and discharge options that may otherwise apply. No general rate or savings estimate can determine whether refinancing benefits an individual borrower.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Federal IDR may be a better fit for someone whose federal payment needs to respond to income or family circumstances, or who may use a federal forgiveness or discharge route. A lower IDR payment does not necessarily mean a lower total amount paid: the plan formula, repayment period, interest, and any eventual discharge all matter. Use the federal estimate and check your program eligibility rather than treating a projected payment as a final cost.
If you have both federal and private loans, assess them separately. A private refinance offer for private debt does not require you to refinance federal debt as well. Keeping the federal loans in the federal system can preserve federal options for those loans while you compare what a lender offers for the private portion.
Be especially cautious if you are enrolled in SAVE or another plan that is changing. Check the latest StudentAid.gov and servicer notices first; do not let an approaching deadline or a lender’s advertised payment substitute for confirming your federal options.

Common comparison mistakes
- Choosing the smallest payment automatically. The payment may be lower because the term is longer, increasing total repayment.
- Using a starting rate as your expected rate. A lender’s final APR depends on its underwriting and the offer you actually receive.
- Ignoring variable-rate risk. A variable rate can rise under the contract, changing the payment or total cost.
- Assuming every federal loan qualifies for every IDR plan. Loan type, first disbursement date and borrower-specific rules matter; Direct parent PLUS loans are excluded from RAP.
- Counting on forgiveness without checking the rules. PSLF, teacher forgiveness and discharge programs have their own employment, payment and eligibility requirements.
- Refinancing all loans together by default. Private and federal loans can be evaluated separately, and including federal loans changes the benefits at stake.
- Missing a transition deadline. SAVE borrowers should read the servicer’s notice; failing to choose another plan by the final 30-day deadline may result in enrollment in a standard plan based on loan timing.
- Paying for a free federal application. Federal Student Aid and federal servicers provide IDR application help without a required fee.
What should I do before signing a refinance offer?
Pause long enough to confirm both the offer’s financial terms and the federal benefits at stake. A careful review can prevent a borrower from mistaking a smaller monthly bill for an unambiguously cheaper or more flexible loan.
- Confirm which loans the lender would pay off and whether any are federal.
- Compare APR, fixed versus variable rate, payment, term, total expected repayment, and disclosed fees or conditions.
- Ask how a variable rate could change under the contract and whether the quoted payment depends on a particular term.
- Review private-lender relief, deferment, forbearance, and discharge terms in writing; do not treat them as equivalent to federal protections.
- Check PSLF or other forgiveness and discharge eligibility before refinancing federal loans.
- Save your federal loan information and estimates, and verify your current plan and any servicer deadline in your account.
- Confirm whether the lender’s offer is for the full balance or only selected loans, and keep documentation showing which accounts were paid off.
If the offer is difficult to compare with the federal estimate, ask the lender to explain the total repayment calculation and any conditions that could change the rate or payment. A headline rate or payment is not the full contract.
Questions borrowers often ask
Can I refinance only my private student loans and keep my federal loans in IDR? You can evaluate loans separately: a refinance offer can be limited to the loans included in the new private loan. Confirm in writing which balances the lender will pay off, and do not include federal loans unless you have considered the federal benefits you would lose.
Does refinancing federal student loans make them eligible for PSLF again later? No. A private refinance pays off the federal loan, so the refinanced debt is no longer eligible for federal PSLF. A private lender’s own repayment or forgiveness feature, if any, is not federal PSLF.
Is federal student loan consolidation the same as refinancing? No. This article’s refinancing comparison concerns replacing debt with a new private loan. Federal consolidation is a separate federal process, so check Federal Student Aid’s rules before deciding whether consolidation addresses your goal.

What should a SAVE borrower do first? Check the current Federal Student Aid transition page, your StudentAid.gov account and your servicer notice. SAVE is no longer available, and the notice may set a final 30-day deadline to choose another eligible plan.
Can a private lender’s hardship policy replace federal forbearance? Not automatically. A private lender’s relief is contract-specific, may have different eligibility rules and is not the federal deferment or forbearance program. Read the terms before treating it as a substitute.

The Bottom Line
IDR and private refinancing solve different problems. Use your StudentAid.gov account and Loan Simulator to identify eligible federal plans, then compare any real refinance offer by APR, rate type, term, payment and total repayment. If refinancing federal loans, decide only after valuing the federal IDR, hardship, forgiveness and discharge protections you would permanently give up.
