Purdue University-Main Campus prices its education differently across income levels, and the spread is meaningful. Low-income families pay approximately $5,098 per year in net price, middle-income families see annual costs around $9,438, and higher-income families pay closer to $22,742. Azimuth ranks Purdue University-Main Campus #345 for post-graduation affordability among nonprofit four-year institutions. That standing reflects Purdue's public-tuition structure and the earnings power graduates bring to loan repayment, particularly in engineering and technical fields where starting salaries tend to be strong. Net prices by income band are medians within those bands; individual aid packages vary, so some families in each band pay more and some less than the figures shown — a dynamic explored further in the net price illusion. Purdue participates in federal, state, and institutional aid programs, and need-based aid plays a meaningful role in shaping what lower- and middle-income families actually pay. The gap between sticker price and net price is most pronounced for low-income students, where grant and scholarship dollars close a substantial portion of the published cost. Families applying for aid use the FAFSA, and Purdue's aid office processes both need-based and, where applicable, merit-based awards that together determine the net price each household faces. Median federal student loan debt at graduation is $19,500, and families using Parent PLUS borrow a median of $29,448; private or institutional loans may add further borrowing that falls outside these federal-only figures — see the for how household context shapes PLUS decisions. For a graduate at Purdue University-Main Campus's median four-year earnings of $81,751, median federal debt of $19,500 projects to a monthly payment of about $220 under standard ten-year repayment.
