Average in-state tuition at public colleges varies enormously across the country, ranging from around $6,360 a year in Wyoming to more than $17,000 in parts of New England, according to College Board data for the 2024 to 2025 school year. Where a student lives, it turns out, can matter as much as where they enroll.
The Cheapest and Priciest States for In-State Students
Four states stand out for affordability: Florida, North Carolina, Utah, and Wyoming all charged in-state students between $6,360 and $8,000 a year for tuition in 2024 to 2025. That is a fraction of what families pay elsewhere.
On the other end, Connecticut, New Hampshire, New Jersey, and Vermont each averaged more than $17,000 a year in in-state tuition. All four are in the Northeast, a region that has consistently run above the national average for public college costs.
Nationally, the average in-state tuition for a four-year public university sits at $11,610 a year, which is actually 10 percent lower than it was five years earlier, once adjusted for the passage of time. Georgia posted the steepest drop among all states, down 21 percent since 2019 to 2020, and 18 states saw declines of at least 10 percent. Only five states saw their in-state tuition costs climb over that stretch.
Why Out-of-State Tuition Costs So Much More
Leaving your home state for college gets expensive fast. The national average for out-of-state tuition at a four-year public university is $30,780 a year, nearly three times the in-state figure.
Michigan charges the most for out-of-state students, at $42,280 a year, and its in-state to out-of-state gap, $26,360, is the second widest in the country. California holds the top spot for the largest gap overall, at $26,820 between what residents and nonresidents pay.
North Dakota and South Dakota tell a different story. The gap between in-state and out-of-state tuition in those states is just $4,320 and $3,550 a year, respectively, meaning nonresidents pay only a modest premium over locals. That also makes them the two most affordable states in the country for out-of-state students, with average costs of $14,790 in North Dakota and $12,740 in South Dakota.
Comparing Tuition Across States
| State or Category | Average In-State Tuition | Average Out-of-State Tuition |
|---|---|---|
| Wyoming (lowest in-state) | $6,360 | N/A |
| Florida, North Carolina, Utah | $8,000 or below | N/A |
| National average | $11,610 | $30,780 |
| Connecticut, New Hampshire, New Jersey, Vermont | Over $17,000 | N/A |
| Michigan (highest out-of-state) | N/A | $42,280 |
| South Dakota (lowest out-of-state) | N/A | $12,740 |
What Families Can Do With This Information
Residency status is the single biggest lever families have over tuition costs, short of choosing a private school or skipping the traditional four-year path altogether. Students weighing schools far from home should factor the out-of-state premium into their decision, not just sticker price at a glance.
Saving early still matters regardless of which state a family calls home. Financial planners generally recommend starting a dedicated education fund, such as a 529 plan, as soon as possible, since even modest, steady contributions add up over a decade or more.
Will the Regional Tuition Gap Keep Widening?
Tuition trends over the past five years suggest costs are easing in most states even as a handful of expensive states pull further ahead. Whether Northeastern states narrow that gap, or whether places like Michigan and California widen their out-of-state premiums further, will shape how families weigh in-state options against dream schools out of state in the years ahead.
