What is a college income-share agreement?

A college income-share agreement, or ISA, is a contract between a student and a college where a student receives education funding from the college today in exchange for agreeing to pay a percentage of future earnings to the college for a specified period of time after graduation. The idea behind ISAs is to minimize the need for private student loans, to give colleges a stake in their students' outcomes, and to give students the flexibility to pursue careers in lower-paying fields.

Purdue University was the first college to introduce such a program in 2016. Under Purdue's ISA program, students who exhaust federal loans can fund their education by paying back a share of their future income, typically between 3% to 4% for up to 10 years after graduation, with repayment capped at 2.5 times the initial funding amount.¹

A handful of other colleges also offer ISAs; terms and eligibility requirements vary among schools.

ISAs are considered friendlier than private student loans because they don't charge interest, and monthly payments are based on a student's income. Typically, ISAs have a minimum income threshold, which means that no payment is due if a student's income falls below a certain salary level, and a payment cap, which is the maximum amount a student must pay back relative to the initial funding amount. For example, a payment cap of 1.5 means that a student will pay back only 1.5 times the initial funding amount. Even with a payment cap, a student's payment obligation ends after the stated fixed period of time, regardless of whether he or she has fully paid back the initial loan.
