Public colleges are usually cheapest for in-state students, while private colleges charge more on paper. Average 4-year tuition and fees were $9,800 at public institutions and $40,700 at private nonprofits in 2022 to 2023, but after grants the average net price was $15,200 at public 4-year colleges and $29,700 at private nonprofits, so the real gap is about double, not quadruple.
That's the number families miss. The sticker price makes private colleges look four times dearer. Once grant and scholarship aid comes off, the gap shrinks a lot, and for some students it closes.
Everything below comes from the National Center for Education Statistics (NCES), the US Department of Education's statistics agency, read in October 2026.
The cost gap: sticker price
| Average tuition and fees, 2022 to 2023 (NCES) | 4-year | 2-year |
|---|---|---|
| Public | $9,800 | $4,000 |
| Private nonprofit | $40,700 | $19,500 |
| Private for-profit | $18,200 | $16,300 |
Public figures use in-state or in-district tuition, whichever is lower. NCES also notes that across all types of degree-granting institutions, average tuition and fees rose by less than inflation between the 2021 to 2022 and 2022 to 2023 academic years, so in constant dollars they fell slightly.
The cost gap: what students pay after aid
Net price is the total cost of attendance minus grant and scholarship aid. It's the better number for comparing colleges, because private nonprofits tend to give more aid.
| Average net price, first-time full-time students at 4-year colleges, 2021 to 2022 (NCES, constant 2022 to 2023 dollars) | Net price |
|---|---|
| Public | $15,200 |
| Private nonprofit | $29,700 |
| Private for-profit | $24,400 |
Notice that net price at a public college is higher than its tuition. That's because net price includes books, room and board, which tuition doesn't. Where you live matters too: NCES says total cost was higher for students living on campus, or off campus but not with family, than for those living at home.
Do private colleges graduate more students?
A little, on average. For students who started a bachelor's degree at a 4-year institution in fall 2014, NCES reports a 6-year graduation rate at the same institution of 63 in every 100 at public colleges, 68 in every 100 at private nonprofits and 29 in every 100 at private for-profits.
The bigger driver is selectivity. NCES found retention rates were highest at the most selective colleges, those accepting fewer than a quarter of applicants, whether public or private. At public 4-year institutions, retention was 82 in every 100 overall but 96 in every 100 at the most selective ones.
The 10-year trend is moving in opposite directions
Over the decade to 2022 to 2023, the two sectors drifted apart. NCES reports average 4-year tuition and fees fell at public institutions, from $10,400 in 2012 to 2013 to $9,800, and rose at private nonprofits, from $37,600 to $40,700, in constant dollars. Public and for-profit 4-year tuition were at their lowest point of the decade in 2022 to 2023.
Two-year colleges flip the pattern
At 2-year colleges, the graduation picture reverses. For students who started a certificate or associate's degree in fall 2017, NCES reports the share completing within one and a half times the normal time was 29 in every 100 at public 2-year institutions, 52 at private nonprofits and 61 at private for-profits. Public community colleges are far cheaper, at $4,000 in average tuition and fees, but NCES also notes that public 2-year institutions had the highest shares of students who had transferred to a different institution or were still enrolled, so a lower completion rate doesn't always mean dropping out. Many community college students move on to a 4-year college before they finish.

How to compare a public and a private college
- Compare net price, not sticker price. Use each college's net price calculator if it publishes one.
- Check your in-state status. Public tuition in the NCES figures is the in-state or in-district rate; out-of-state students usually pay more.
- Look at the graduation rate for that specific college, not the national average.
- Add living costs. Living at home changes the total more than the public or private label does.
- Check for-profit colleges closely. Their 6-year graduation rate at 4-year institutions in the NCES data was well under half the nonprofit rate.

My verdict
Don't rule a private college out on its sticker price, and don't assume a public college is automatically the cheap option once you add room and board. Run the net price calculator for every college on your list, compare graduation rates for those exact colleges, and take living at home seriously if it's an option. On the NCES numbers, a public in-state college still wins on average cost, but a generous private nonprofit offer can close more of the gap than most families expect.
Frequently asked questions
Is a public college cheaper than a private college?
On average, yes. NCES reports average 4-year tuition and fees of $9,800 at public institutions and $40,700 at private nonprofits in 2022 to 2023, as of October 2026.
What is the net price of college?
Net price is the total cost of attendance minus grant and scholarship aid. NCES puts the 2021 to 2022 average at $15,200 for public 4-year colleges and $29,700 for private nonprofits, in constant 2022 to 2023 dollars.
Do private colleges have higher graduation rates?
Slightly. NCES reports 6-year graduation rates of 63 in every 100 at public 4-year colleges and 68 in every 100 at private nonprofits, for students starting in fall 2014.
What's the difference between private nonprofit and for-profit colleges?
Both are private, but they differ in cost and outcomes. NCES shows lower average tuition at for-profit 4-year colleges than at nonprofits, but a 6-year graduation rate of 29 in every 100.
Are community colleges cheaper than 4-year colleges?
Yes. NCES reports average tuition and fees of $4,000 at public 2-year institutions in 2022 to 2023, compared with $9,800 at public 4-year institutions.
Does living at home make college cheaper?
Yes. NCES says total cost of attendance was lower for students living off campus with family than for those living on campus or off campus without family.
