Neither answer is right for everyone. Every extra dollar you put on a student loan earns that loan’s interest rate, guaranteed, so a high-rate private loan is often worth paying down fast. Federal loans are different: forgiveness programs, the new Repayment Assistance Plan and the tax on forgiveness can make extra payments worth less than they look. Start by knowing which kind of loans you have, then weigh your rate, taxes, risk and how much cash you need to reach.
This guide is about the pay-or-invest choice. For free help applying for federal plans, see affordable financial advice. For PSLF in medical careers, see financial advisors for doctors.
First, sort your loans
Your federal loans are listed in your StudentAid.gov account; anything else is private. The two follow different logic.
- Private loans are a plain debt. The choice is your rate against what the money would earn elsewhere. Paying down a 9% private loan earns 9% with certainty, far above the 4.94% a 10-year Treasury yielded on October 30, 2026.
- Federal loans come with options private lenders don’t offer: payments tied to income, forgiveness, and pauses for hardship. Those options have value, and paying a loan off early, or refinancing it with a private lender, gives them up. Federal plans such as RAP and PSLF apply only to federal loans.
The 2026 federal rules that matter
The Repayment Assistance Plan
RAP became available on July 1, 2026. Under the law that created it:
- Your payment is 1% to 10% of adjusted gross income, depending on income, divided by 12, minus $50 a month for each dependent. The minimum is $10 a month.
- If an on-time payment doesn’t cover the month’s interest, the unpaid interest is waived, so the balance doesn’t grow.
- If an on-time payment reduces principal by less than $50, the government makes up the difference, up to the amount you paid.
- Anything left after 360 qualifying payments, 30 years, is canceled.
These follow the statute’s brackets: 2% of income at $30,000, 4% at $50,000, 7% at $75,000, 9% at $100,000 and 10% above that. For a married borrower filing jointly, the income counted includes a spouse’s.
The tax on forgiveness
Federal law excluded forgiven student debt from income for discharges through 2025. That exclusion has ended, so forgiveness after long income-driven repayment counts as taxable income again. Two exclusions remain: Public Service Loan Forgiveness, which is tied to working for qualifying employers, and discharges because of death or total and permanent disability. If you expect forgiveness under RAP or an older income-driven plan, plan for a tax bill in the year it happens.
Tax breaks and employer help
- Interest deduction. You can deduct up to $2,500 of student loan interest a year without itemizing, though it phases out at higher incomes. It slightly lowers your effective rate.
- Employer payments. An employer can pay up to $5,250 a year toward your loans tax-free through an educational assistance program.
- Matched loan payments. Since 2024, a 401(k), 403(b), SIMPLE IRA or governmental 457(b) plan can match your student loan payments as though they were retirement contributions, if the plan adopts the feature. That lets you pay down debt without giving up the match.
How the choice turns
| Your situation | Leans toward | Why |
|---|---|---|
| On track for PSLF | Pay the required amount, invest the rest | Extra payments shrink the amount forgiven |
| Long income-driven repayment, forgiveness likely | Pay the required amount, save for the tax | Forgiveness is taxable again from 2026 |
| Private loan, rate well above safe yields | Pay down | A guaranteed return at your loan’s rate |
| Low-rate federal loan, no employer match yet | Invest enough for the match | A match is an immediate return no loan payoff beats |
| Income uncertain, little cash | Build cash first | Cash covers emergencies, and federal plans can lower payments if income drops |
Rates. The higher your rate compared with what safe money earns, the stronger the case for paying down. The deduction trims the rate a little if you qualify.
Taxes. Retirement accounts grow without yearly tax: up to $24,500 in a 401(k) and $7,500 in an IRA for 2026. Taxable forgiveness at the end of an income-driven plan works against you and has to be planned for.
Risk. Paying down debt is certain; investing isn’t. Federal loans also carry a kind of insurance: if your income drops, your RAP payment drops with it. Private loans don’t.
Liquidity. A dollar sent to a lender is gone. A dollar in savings can cover a job loss. Keep an emergency fund before making extra payments.
Common mistakes
- Paying extra on a PSLF track. It feels responsible and costs you money.
- Refinancing federal loans that were headed for forgiveness. A lower private rate can cost more than the forgiveness you give up.
- Skipping the 401(k) match to throw everything at the loans.
- Forgetting the tax on forgiveness, then facing it in one year with nothing set aside.
- Paying a company to enroll you in a federal plan. Applying is free.
Questions to ask an advisor
| Ask | A good answer includes |
|---|---|
| Which plan gives me the lowest total cost, and the lowest risk? | The payment under each option, and total paid over time |
| Am I likely to get forgiveness, and what tax would I owe? | An estimate in dollars and a plan to save for it |
| Should I refinance any of my loans? | Which loans, and what I’d give up |
| Does my employer match loan payments or pay toward loans? | They’d ask you to check your plan documents |
| How are you paid? | A fixed fee, with nothing from lenders or refinancing companies |
When advice is worth it, and what it costs
A planner earns the fee when the balance is large, when forgiveness is in play, or when you’re weighing loans against a home purchase or retirement saving. For most borrowers this is a one-off project: a fee-only planner who bills by the hour charges a median $300 an hour (middle half $250 to $350), and a one-time plan has a median of $2,000. Of 781 US fee-only firms whose websites state an asset minimum, 50% say they have none. A fee-only planner earns nothing from refinancing lenders, so the recommendation isn’t steered by a referral fee. See what an hourly planner costs and what a one-time plan costs.
How to find one
In the public graph, browse the student loans specialty, advisors for early-career professionals and advisors for HENRYs. Physicians and dentists can start with the physicians specialty or physicians audience page. If a mortgage is your bigger debt, read pay off the mortgage or invest, and if you’re saving for a first home, buying your first home.
