College is an investment with a measurable return, and this section measures it in dollars. Every page here answers one question: what a degree costs after aid, what it pays, and how many years the paycheck takes to clear the bill. No brochure adjectives, no rankings-speak — the arithmetic, with each figure carrying its source and its date.
Start by ignoring the sticker. A public four-year college posts a $30,990 published price, but aided families pay $13,788 net; private nonprofits net $26,597 against a $65,470 sticker (College Board 2025-26 sticker; College Scorecard net, June 2026). The gap between the two runs from $10,000 to more than $50,000 a year, which is why an offer is judged on net price and never on the headline. The cost pages break that net figure down by sector, by family income, and into the four-year total most households actually finance.
Earnings get measured the same way — from what graduates report to the IRS, not what a school advertises. Pay tracks the field, not the diploma. Nursing carries the highest starting salary of any major at $83,188, though a new-grad RN in practice lands between $66,030 and $78,610 in year one (College Scorecard, June 2026; BLS 10th-25th percentile). Four years out, computer-engineering graduates lead the bachelor's-only paths near $112,269. The earnings pages rank majors on those tax-record numbers so every comparison is like-for-like.
ROI is where cost and earnings meet. The median bachelor's degree returns $261,424 over 20 years from enrollment — a 105% return on the full stake of net cost plus the wages forgone during four years of study (our math). The spread inside that median is the real story: engineering repays a public degree's net cost in about 1.2 years, while some education paths need 63.5. Against that return sits the average debt load of $40,467 per borrower, roughly $460 a month on the standard 10-year plan (U.S. Dept. of Education, March 2026). A degree is a good deal when net cost is repaid within about five years; the median field clears it in 3.2.
One yardstick runs through every page. Cost comes from Scorecard net price and College Board sticker data; earnings come from Scorecard's field-of-study tax records; debt comes from Federal Student Aid. Where a number is computed here rather than reported — the 20-year return, a payback period — it is marked our math and the formula is shown. The Scorecard median is a consistent measuring stick across fields and schools, not a personal quote; any one student's figure moves with aid, major, and school. Note the unit throughout: net price and salary are annual, debt is a total balance, and payback is counted in working years.
This section is built for the person doing the comparison, not browsing it. A 17-year-old weighing two acceptance letters on net price. A parent checking whether a $55,152 four-year bill clears against a plausible starting salary. A returning adult measuring new debt against the raise a specific field pays. Anyone after a marketing ranking is in the wrong place; anyone after the math is in the right one.
Where to start depends on the decision in front of you. Choosing a major points to the ROI-by-major ranking, the spine of this section, which sorts 30 fields by payback years. Choosing a school points to the institution ranking across 1,944 bachelor's colleges. Checking a single number — average cost, average debt, a good-ROI threshold, a nursing salary — points straight to that page. Every calculation here is reproducible: the inputs, the formulas, and the Scorecard and IPEDS sources sit in the methodology, so any number on any page traces back to its raw table.
