Grab any employer 401(k) match first — it is an instant 50%–100% return. After that, compare your loan’s rate with what you reasonably expect to earn after tax. Paying down a 8.07% or 9.07% loan is a guaranteed return that is hard to beat; for a loan near 6.52%, investing has historically had a chance to come out ahead over long periods but with real risk. If you are pursuing PSLF or expect RAP forgiveness, extra payments may simply reduce what gets forgiven.
Step 1: the order of operations
- Emergency fund: a few months of expenses, so a job loss doesn’t push you into forbearance or credit card debt.
- 401(k) match: contribute enough to get the full employer match.
- High-rate debt: credit cards, then private or PLUS loans above roughly 8%.
- Tax-advantaged accounts: Roth IRA / HSA / more 401(k), especially if your loan rate is in the 4%–6% range.
- Then: split extra money between low-rate loans and investing based on your risk tolerance.
10-year example: $300 a month, two ways
You owe $30,000 at 6.52% (10-year payment $341) and have an extra $300 a month. Option A: put it on the loan — it’s gone in 4 yr 7 mo, saving $6,203 of interest — then invest the full $641 until year 10. Option B: pay the minimum and invest $300 for 10 years. Wealth after 10 years at different annual returns:
| Annual return (illustrative) | A: pay off, then invest | B: invest from day 1 | Better |
|---|---|---|---|
| 4% | $47,106 | $44,175 | Pay off first |
| 6.52% | $50,576 | $50,576 | Invest |
| 8% | $52,767 | $54,884 | Invest |
| 10% | $55,923 | $61,453 | Invest |
When returns equal the loan rate the two options tie; above it investing wins, below it paying off wins. Returns are illustrative, not predictions — markets can lose money, and taxes and fees reduce investment returns, while the loan “return” is guaranteed.
When paying off student loans wins
- Your rate is high: graduate (8.07%), PLUS (9.07%) or private loans.
- You value the psychological and cash-flow benefit of being debt-free — for example before buying a home.
- Your income is high enough that the student loan interest deduction phases out (it starts at $85,000 MAGI single in 2026).
- You are on the Tiered Standard or a standard plan with no forgiveness in sight.
When investing (or paying the minimum) wins
- You are on track for PSLF: extra payments reduce your tax-free forgiveness.
- Your RAP or IBR projection shows a large balance forgiven anyway.
- You aren’t yet getting your full 401(k) match.
- Your loans are older, low-rate loans (some 2020–2021 loans carry rates under 4%).

Frequently asked questions
Is it better to pay off student loans or invest?
Take any 401(k) match first. Then, if your loan rate is above what you’d confidently expect to earn after tax (often the case above 7%–8%), pay down the loan; if it is low, investing may come out ahead but with risk.
Should I pay off student loans early if I’m going for PSLF?
Usually not. Under PSLF the remaining balance is forgiven tax-free after 120 qualifying payments, so extra payments just reduce the amount forgiven.
How much do I save paying an extra $300 a month on $30,000?
At 6.52%, the loan is paid off in about 4 yr 7 mo instead of 10 years and you save about $6,203 in interest.
Does the student loan interest deduction change the math?
Slightly. Up to $2,500 of interest is deductible if your MAGI is under the 2026 phase-out, which lowers your effective rate a little for borrowers who qualify.
