Income Share Agreements: Are They Worth It?

You have your financial aid offer, you have run the numbers, and there is still a gap between what college costs and what you can pay. Before you sign for a traditional student loan, you may have heard about another option: an income share agreement, or ISA. Instead of borrowing a fixed amount at a fixed interest rate, you agree to pay a percentage of your income after graduation for a set number of years. If you earn a lot, you pay more. If you earn less, you pay less. And if you earn nothing, you might not pay anything at all. But like most things in college financing, the details matter far more than the pitch. Some students have done well with ISAs. Others have paid significantly more than they would have with a federal loan. Before you commit, you need to understand how these agreements work, which schools still offer them, and how they stack up against the alternatives.

What Is an Income Share Agreement?

An income share agreement is a contract between you and a school, fund, or private company. In exchange for funding part of your education, you agree to pay a percentage of your post-graduation income for a fixed period once you earn above a certain threshold.

The basic terms include:

• Income share percentage: The portion of your gross monthly income you agree to pay, typically ranging from 2% to 10% depending on the program and your major.
• Payment window: The number of months you make payments, usually between 24 and 120 months (two to ten years).
• Minimum income threshold: The annual salary below which you owe nothing. Most ISAs set this somewhere between $20,000 and $30,000.
• Payment cap: The maximum total amount you can ever be required to pay, often expressed as a multiple of the original funding amount (for example, 1.5x or 2.5x what you received).

Here is a concrete example. Say you receive $15,000 through an ISA with a 5% income share, a 100-month payment window, and a $25,000 minimum income threshold. If you graduate and earn $50,000 per year, you pay 5% of gross income -- $2,500 per year, or about $208 per month -- for up to 100 months. Total repayment at that salary: roughly $20,833 over eight years and four months.

How ISAs Differ from Loans

The biggest structural difference is that ISAs do not carry a stated interest rate. Federal student loans for the 2025-26 academic year carry a fixed rate of 6.53% for undergraduate Direct Loans. Private loans range from roughly 4% to 17% depending on credit profile and lender.

With a loan, you know the rate upfront and can calculate your total cost. With an ISA, your total cost depends entirely on what you earn after graduation. If you land a high-paying job quickly, you could pay well above what a loan would have cost. If you struggle to find work, the ISA's protections could save you thousands.

Another key difference: most ISAs are not classified as loans under federal law, though the CFPB has increasingly treated them as credit products subject to truth-in-lending requirements. This affects your legal protections and whether the agreement shows up on your credit report.

Which Schools and Programs Still Offer ISAs

The ISA landscape has changed significantly since these agreements peaked around 2019-2021. Several high-profile programs have shut down, and the number of schools offering ISAs has shrunk.

Schools with Active or Recent ISA Programs

• Purdue University launched one of the most well-known ISA programs, Back a Boiler, in 2016. The program funded over $18 million for more than 1,100 students before Purdue stopped accepting new ISA applications in 2024. Students already in the program continue under their original terms, but new students cannot apply.
• Messiah University in Pennsylvania has offered ISAs as an alternative to Parent PLUS Loans. Terms vary by major and expected post-graduation earnings.
• Coding bootcamps like Lambda School (now BloomTech) were early adopters. BloomTech required students to pay 17% of income for 24 months once they earned above $50,000. However, BloomTech faced scrutiny from the CFPB in 2023 for misleading students about job placement rates and ISA terms, and the company shut down.
• Private ISA funds like Vemo Education previously partnered with dozens of colleges to administer ISA programs. Vemo ceased operations in 2022, taking many school-based ISA options with it.

Why ISAs Are Becoming Less Common

Three forces have squeezed the ISA market:

1. Regulatory uncertainty: The CFPB's 2023 enforcement action against BloomTech signaled stricter oversight ahead. Schools and funds became wary of legal risk.
2. High administrative costs: Tracking graduates' incomes, collecting variable payments, and managing deferments is expensive compared to certifying a federal loan.
3. Improved federal options: The SAVE repayment plan (paused due to litigation as of early 2026) and other income-driven repayment plans offer similar income-based protections without the complexity of an ISA.

How to Compare an ISA to Federal Student Loans

The smartest way to evaluate an ISA is to model your costs under multiple income scenarios and compare them to federal loan repayment.

Running the Numbers: A Side-by-Side Example

Say you need $15,000 to cover a funding gap for your junior year.

Option A: Federal Direct Unsubsidized Loan

• Amount borrowed: $15,000
• Interest rate: 6.53% (2025-26 rate)
• Loan fee: 1.057%, so about $159 deducted upfront
• Standard 10-year repayment: roughly $170/month, with a total repayment of about $20,400

Option B: ISA at 5% of Income for 100 Months

• Funding received: $15,000
• If you earn $40,000/year: you pay $2,000/year, totaling about $16,667 over 100 months
• If you earn $60,000/year: you pay $3,000/year, totaling about $25,000 over 100 months
• If you earn $80,000/year: you pay $4,000/year, totaling about $33,333 over 100 months (unless the payment cap kicks in)

At lower incomes, the ISA costs less. At higher incomes, it costs significantly more. The crossover point here falls around $49,000 in annual earnings. Above that, the federal loan is cheaper.

What About Income-Driven Repayment Plans?

Federal loans come with income-driven repayment (IDR) plans that cap payments at a percentage of your discretionary income, similar to an ISA. Under the SAVE plan, undergraduate borrowers would pay 5% of discretionary income (income above 225% of the federal poverty level, which is $33,885 for a single person in 2025). Remaining balances are forgiven after 20 years. Federal loans already have a built-in income-based safety net plus forgiveness, which ISAs do not offer.

When an ISA Might Make Sense

Despite the drawbacks, there are situations where an ISA could be reasonable:

• You have maxed out federal loans. Undergraduates can borrow a maximum of $5,500 to $7,500 per year in Direct Loans depending on year and dependency status, with a cumulative cap of $31,000. If your gap exceeds that and you want to avoid private loans or Parent PLUS Loans, an ISA might fill the space.
• You are entering a field with uncertain early earnings. If you plan to start a business or enter a field with unpredictable income, the ISA's minimum income threshold protects you during lean years.
• You cannot qualify for a private loan. Private lenders typically require a creditworthy cosigner or strong credit history. ISAs usually do not check credit, making them accessible when other options are not.
• The specific ISA terms are genuinely favorable. Some school-based ISAs have low income share percentages (2-3%), short payment windows, and reasonable caps. If the math works out cheaper than a private loan at 10%+ interest, it could make sense.

When an ISA Is Probably Not Worth It

For many students, ISAs carry risks that other options handle better.

• You are entering a high-earning field. If you are studying computer science, engineering, nursing, or finance and expect a starting salary above $55,000, the ISA's income-based payments could cost you thousands more than a fixed-rate loan.
• The payment cap is high. Some ISAs cap total repayment at 2x or 2.5x the amount funded. On a $15,000 ISA, a 2.5x cap means you could pay up to $37,500 -- far more than any federal loan would cost.
• You have access to federal loans. Federal Direct Loans should almost always come first. They offer fixed rates, income-driven repayment, deferment, forbearance, and forgiveness programs like Public Service Loan Forgiveness. ISAs offer none of these.

Challenges to Watch For

Regulatory Gray Areas

ISAs sit in an awkward legal space. They are not technically loans in most states, which means they may not be covered by the same consumer protection laws. The CFPB has argued that ISAs are credit products subject to the Truth in Lending Act, but courts have not universally adopted this view. If a dispute arises, your legal remedies may be limited compared to a regulated loan.

Hidden Costs and Fine Print

Read every ISA contract carefully. Roadblocks to watch for:

• Gross vs. net income: Most ISAs calculate payments on gross income (before taxes), not take-home pay. Five percent of gross is meaningfully more than 5% of net.
• Payment obligations during low-earning months: Some ISAs pause payments when income drops below the threshold, but paused months may not count toward your payment window. If they do not, you could pay for much longer than expected.
• What counts as "income": Some contracts define income broadly to include freelance work, bonuses, and investment gains. Others stick to W-2 wages. The definition affects total cost.
• Early repayment terms: Some ISAs let you buy out your agreement at a fixed amount, while others offer no buyout option at all.

Limited Availability

The number of ISA programs has declined sharply. If you are counting on an ISA to fill your funding gap, your school may not offer one. Confirm availability directly with your financial aid office before building your plan around this option.

Tax Treatment Uncertainty

The IRS has not issued clear guidance on whether ISA payments are deductible like student loan interest. Under current law, you can deduct up to $2,500 per year in student loan interest. Whether ISA payments qualify is unclear, and some tax professionals advise against claiming it without explicit IRS guidance. You could miss out on a tax benefit that loan borrowers routinely receive.

The Bottom Line

Income share agreements were designed to solve a real problem: students taking on fixed debt without knowing what they would earn after graduation. The concept of tying payments to income is sound, and federal income-driven repayment plans prove it works. But ISAs as they exist today come with significant uncertainty -- regulatory, financial, and practical. The market is shrinking, consumer protections are uneven, and for most students, federal loans with income-driven repayment offer the same downside protection plus forgiveness benefits that ISAs cannot match.

If you are considering an ISA, model the numbers at multiple salary levels. Compare the total cost to a federal Direct Loan and, if needed, a private loan. Pay close attention to the payment cap, the income share percentage, and how the ISA defines income. And exhaust your federal loan options first. The ISA should be a last resort, not a first choice.

Frequently Asked Questions

Are income share agreements legal?

Yes. ISAs are legal, though they face increasing regulatory scrutiny. The CFPB has taken the position that many ISAs function as credit products and should follow truth-in-lending rules. Several states, including Colorado and Connecticut, have passed laws specifically regulating ISAs.

Do ISA payments show up on my credit report?

It depends on the provider. Some ISA administrators report payments to credit bureaus, and some do not. If reported, missed payments could hurt your credit score. Ask your provider before signing.

Can I pay off an ISA early?

Some ISAs include a buyout provision that lets you pay a lump sum to end the agreement early. Others do not. The buyout amount is usually a fixed figure listed in your contract. Check the terms before signing.

What happens if I lose my job after graduation?

Most ISAs have a minimum income threshold (usually $20,000 to $30,000). If earnings fall below that, payments are paused. Whether paused months count toward your total payment window varies by contract, so read the fine print.

Are ISA payments tax-deductible?

The IRS has not issued clear guidance. Student loan interest is deductible up to $2,500 per year, but since ISAs are not technically loans, claiming the deduction is a gray area. Consult a tax professional if you are making ISA payments.

How do ISAs compare to Parent PLUS Loans?

Parent PLUS Loans for 2025-26 carry a fixed rate of 8.94% plus a 4.228% loan fee -- expensive terms. An ISA might cost less if the student earns a moderate salary after graduation. However, Parent PLUS Loans come with federal protections, IDR eligibility through the ICR plan after consolidation, and potential PSLF eligibility that ISAs cannot match.
