Student loans vs
investing.

The math

Every dollar that pays down a loan at 6% earns you a guaranteed 6% return, before taxes. Every dollar invested in stocks returns an expected ~7% long-term, but with volatility and no guarantee.

The simple rule: if your loan rate is below your expected investment return after tax, investing usually wins long-term. If your loan rate is above 7%, pay it off aggressively. A guaranteed return is hard to beat.

Federal vs private loans

Federal student loans come with protections private loans simply do not. Income-driven repayment plans, forbearance, deferment, interest-rate caps, and loan forgiveness options all apply only to federal debt. Federal rates for undergraduate, graduate, and PLUS loans typically fall in the 5 to 8% range^[4] .

Private loans are ordinary consumer debt with a degree attached. Treat them accordingly. Private rates commonly land in the 8 to 12%+ range^[5] . If you have private loans above 7%, they belong ahead of investing in the queue.

Income-Driven Repayment (IDR)

IDR plans cap your monthly payment as a percentage of discretionary income. The three main ones:

The Order of Operations, applied

If you carry student loans, here's how to sequence your paycheck:

Can you buy Bitcoin while carrying student loans?

Short answer: if your federal loan rate is below 5%, and you've already cleared steps 1 to 4 above, yes. 1 to 5% of your paycheck into Bitcoin DCA does not meaningfully slow your loan payoff and builds a long-term position while you are young enough for time to compound.

If your loan rate is above 7%, nuke the loan first. A guaranteed 7% is very hard to beat and it frees cash flow permanently once it's gone.

PSLF (Public Service Loan Forgiveness)

If you work for the government, a 501(c)(3) nonprofit, or a qualifying educational institution, PSLF forgives your remaining federal student loan balance after 120 qualifying monthly payments (10 years) on an IDR plan^[2]. Employer certification is required.

Teachers, social workers, public defenders, city employees, hospital nurses in nonprofit systems. This is the single biggest loan-math lever in the U.S. system and millions don't use it because the paperwork is brutal. If you might qualify, use the PSLF Help Tool on studentaid.gov.

The tax-free forgiveness on PSLF (unlike IDR forgiveness) makes the math dramatic. A teacher who makes $55K and qualifies can see $30K+ erased, tax-free.

Sample 5-year plan

Take-home: $72,000. Student loans: $40,000 at 6% federal. No other debt.

End of Year 5: roughly $25K in retirement accounts, $6K in BTC, $24K loan balance (down from $40K), and habits that compound for 30 years. Not dramatic. That's the point.

PSLF step by step

Public Service Loan Forgiveness (PSLF) discharges remaining federal student-loan balance after 120 qualifying payments while working full-time for a qualifying employer verify×DON'T TRUST, VERIFYClaim: PSLF requires 120 qualifying payments while employed full-time at a qualifying employer.Verify at: studentaid.gov PSLF page ↗120 monthly payments equals 10 years; payments must be on an Income-Driven Repayment plan (or the 10-year Standard plan).. Forgiveness is tax-free at the federal level.

Who qualifies

• Federal government agencies (federal, state, local, tribal)
• Public schools, public universities, and public hospitals
• Nonprofit 501(c)(3) organizations
• Some other not-for-profit organizations that provide qualifying public services

The certification process

Submit the Employment Certification Form (ECF) annually. Do not wait until year 10 to discover that an employer was not qualifying or a payment plan did not count. The PSLF Help Tool at studentaid.gov is the official lookup; results are tied to your specific FEIN.

Common PSLF mistakes

• Being on the wrong repayment plan. Must be an Income-Driven Repayment (IBR, PAYE, SAVE, ICR) or the 10-year Standard plan.
• Consolidating loans incorrectly, which can reset the payment count for some loan types. The 2023 Limited PSLF Waiver fixed many cases retroactively, but new consolidations after the waiver should be done deliberately.
• Working for an employer that seems nonprofit but does not qualify (some public-benefit corporations, certain religious organizations).
• Not submitting ECF annually. The PSLF Servicer (currently MOHELA) cannot count your progress without certification.

See the student loan IDR comparison tool for monthly-payment math under each plan, and consult the official PSLF page for the most current rules.

Parent PLUS Loans: the warning

Parent PLUS Loans are among the most dangerous financial products in the federal student-loan system. They have:

• No standard income-driven repayment options. The Double Consolidation workaround historically allowed access to ICR but its status under recent rule changes is in flux verify×DON'T TRUST, VERIFYClaim: Double Consolidation was a workaround to access broader IDR for Parent PLUS Loans; status is changing.Verify at: studentaid.gov ↗Department of Education has tightened Double Consolidation rules; check current status before relying on it..
• No borrowing limits beyond cost of attendance, so a parent can borrow $40k-$80k per year for a single child.
• Parents take on debt at the peak of their earning years and closest to retirement, with no income-protection safety net.
• Default consequences include garnished Social Security benefits in retirement.
