Quick overview
Income-Share Agreements (ISAs) and student loans both finance education, but they shift risk differently. ISAs transfer repayment risk to the financier by tying payments to earnings. Student loans place repayment responsibility squarely on the borrower, with fixed schedules and interest.
I’ve guided hundreds of clients through these choices. My experience: ISAs work best when career outcomes are uncertain and you value payment flexibility; loans are usually a better match when you expect steady, higher earnings or need widely available federal benefits like income-driven repayment and forgiveness options.
How ISAs work — key mechanics
- Payout: The school or fund provides tuition support or living-cost financing up front.
- Repayment trigger: You begin paying once your earnings exceed a specified minimum (a “minimum income threshold”).
- Payment formula: A fixed percentage of your gross or adjusted income (commonly 2%–20%) is paid for a set term (often 2–10 years).
- Payment caps and pauses: Many ISA contracts include a maximum total payment (a cap) and hardship pauses, but terms vary widely.
Regulation and disclosure standards for ISAs are evolving. The Consumer Financial Protection Bureau (CFPB) has published guidance and consumer alerts about ISAs; check CFPB resources before signing (see sources). Many states also require specific disclosures or licensing for ISA providers.

How student loans work — basics
- Types: Federal loans (Direct Subsidized, Unsubsidized, PLUS) and private loans from banks or specialty lenders.
- Repayment: Borrowers repay principal plus interest according to the loan’s terms. Federal loans typically offer fixed rates and standardized repayment plans; private loans vary.
- Federal borrower protections: Income-driven repayment (IDR), deferment/forbearance, and public service loan forgiveness (PSLF) are available for qualifying federal loans.

Direct comparison: Pros and cons
Pros of ISAs
- Payment flexibility tied to income — helpful during underemployment or career transitions.
- No traditional interest accrual; cost is structured as a share of income rather than interest on principal.
- For some students, ISAs reduce default risk because payments scale with earnings.
Cons of ISAs
- Potentially higher total cost if your income grows quickly or is high throughout the payment window.
- Not widely available — typically offered by select bootcamps, certificate programs, and a few colleges.
- Contract complexity — watch for buried fees, ambiguous income definitions, and limited consumer protections in some states.
Pros of student loans
- Broad availability — federal loans are available to most eligible students and cover diverse program types.
- Predictability — fixed repayment schedules and clear payoff timelines (unless you choose IDR).
- Access to federal benefits, including IDR plans and PSLF for qualifying public service careers.
Cons of student loans
- Interest accrual can substantially increase total cost, especially with long repayment terms or deferment periods.
- Required repayment regardless of employment; missed payments can damage credit.
- Private loans often lack the protections or flexible options of federal loans.
Real-world example (hypothetical to illustrate differences)
Scenario: You need $40,000 to finance a two-year program.
Option A — Federal/private loan example (hypothetical):
- Loan amount: $40,000
- Rate (example): 5% fixed
- Typical 10-year level repayment monthly payment ≈ $424
- Total paid over 10 years ≈ $50,880 (principal + interest)
Option B — ISA example (hypothetical contract):
- Percentage: 10% of gross annual income
- Term: 5 years after employment begins
- Minimum income threshold: $25,000 (no payments until income exceeds this)
If your first-year salary is $60,000 and increases 3% year-over-year, your ISA payments might be:
- Year 1: $6,000
- Year 2: $6,180
- Year 3: $6,365
- Year 4: $6,556
- Year 5: $6,752
- Total over 5 years ≈ $31,853 — significantly less than the loan example.
If, instead, you immediately earn $100,000, the same ISA would cost $50,000 over five years — about equal to or higher than the loan case. That demonstrates the central trade-off: ISAs cap downside risk but can become expensive if you earn well.
Note: These numbers are illustrative. Actual ISA contracts differ in percent, term, and caps.
Key contract terms to analyze in an ISA
When evaluating an ISA, read the contract closely and compare how each clause affects total cost and protections:
- Income definition: Is it gross pay, net pay, or adjusted gross income? Does it include bonuses, stock, or other compensation?
- Minimum income threshold: The lower the threshold, the earlier payments start.
- Payment cap: Is there a maximum total you can be asked to pay? A cap limits upside for the investor but protects the borrower.
- Pause/forgiveness events: Does the ISA pause for extended unemployment, disability, or family leave? Is there a partial or full forgiveness after crisis events?
- Transferability: Can the ISA be sold to another investor? That affects your relationship and dispute resolution.
- Compound definitions and fees: Some ISAs include origination or servicing fees; calculate total expected outflow.
Red flags: ambiguous income definitions, open-ended terms without caps, aggressive collections language, or sellers who refuse to provide past student outcome data.
How to choose — practical decision framework
- Project earnings realistically: Use salary data for your chosen field and factor likely raises. Tools like BLS occupational data can help.
- Build total-cost models: Compare total expected ISA payments under low/median/high salary scenarios to loan amortization schedules. Run sensitivity tests.
- Consider protections you need: If you need IDR, deferment options, or PSLF eligibility, federal loans may be preferable.
- Check availability: If your program or school offers an ISA as a primary option, compare that offer to federal loan eligibility and private loan terms.
- Seek professional advice: Talk to a financial counselor or advisor who understands higher-education financing.
I tell clients to run at least three scenarios — conservative, base, and optimistic — before deciding. For many, the upside of ISAs isn’t worth the uncertainty unless the contract is clear and capped.
Can you mix ISAs and student loans?
Yes. Many students combine financing sources — federal loans for a stable baseline plus an ISA for additional program-specific funding. If you use federal loans, keep in mind combined repayment obligations and the differing protections each instrument provides.

Regulatory, tax, and consumer-protection notes
- ISA oversight is still developing. The CFPB and some state regulators have warned consumers to scrutinize ISA terms. See CFPB guidance for consumers researching ISAs (consumerfinance.gov).
- Federal student loan programs are governed by the U.S. Department of Education; updates to IDR and forgiveness programs continue to evolve — check studentaid.gov for the latest policies.
- Tax treatment: How forgiven or ended ISA obligations are treated for tax purposes can vary. The taxability of forgiven student debt also depends on current law. Consult IRS guidance or a tax professional for your situation.
Common mistakes to avoid
- Signing an ISA without modeling high-earning scenarios.
- Focusing only on monthly payment size instead of total expected payment.
- Assuming an ISA offers the same borrower protections as federal loans (it does not).
- Ignoring definitions of income, bonuses, and equity compensation — these can materially change payments.
Checklist before you sign
- Get the full ISA contract and an itemized disclosure of all fees and caps.
- Ask for historical outcome data: What were median salaries of past participants?
- Confirm whether the ISA provider is regulated in your state or country.
- Compare a conservative loan scenario (with IDR if eligible) to the ISA baseline.
- Talk to a qualified financial counselor about long-term impacts on credit, housing, and retirement planning.
Final takeaway
ISAs shift risk from borrower to investor by tying payments to future income — a compelling option if you expect variable or modest early-career earnings and value downside protection. Student loans remain broadly available and carry benefits like federal repayment plans and forgiveness for qualifying borrowers. The right choice requires careful modeling of likely salary paths, scrutiny of contract terms, and an understanding of available borrower protections.
