How Much Is Home-Field Advantage Worth in College Football?
About 4.3 points a game from 2013 to 2025, more than twice the NFL's, and the line already charges 4.6 for it. Season by season, including 2020.

College home teams won by about 4.3 points a game from 2013 to 2025, more than twice the NFL's 1.9. The betting line charged them a little more than that, 4.6 points on average, and home teams covered 49.0% of the time. Home field is big in college, and the line already knows.
The short answer: about four points
Across 9,049 games between two FBS teams played at one team's stadium from 2013 through 2025, the home team won by 4.33 points on average and won outright 58.4% of the time. Over the same games the closing line made the home team a 4.58-point favorite on average.
The NFL figure over 2015 to 2025 is about 1.9, with the line at about 1.9 too (see how much NFL home field is worth). The usual explanations for the gap are bigger and louder student crowds, longer and less comfortable travel, and younger players. The data here can show the size of the gap, not which of those causes it.

FBS against FBS at one team's home stadium; the 773 neutral-site games (conference title games, bowls, kickoff classics) are left out. Margin and line are from the home team's side. The line is the median closing spread across the books CollegeFootballData.com reports.
2020 stands out. It was played with empty or thinned-out stadiums and a shortened schedule, and home teams won by just 2.13 points, with the lines down to 2.98. Every other season lands between about 3.7 and 5.4. That fits crowds being a large part of college home field. It is one season of 499 games, though, so the size of that part is uncertain.
Home teams against the spread: 49.0%
Because the line charges home teams slightly more than they have delivered, taking the home side every time went 4359–4530–160 against the spread, a 49.0% cover rate. That is about 1.8 standard deviations under 50% over 8,889 decided games: close to the edge of what chance produces, and nowhere near a strategy. Taking the road side would have covered about 51%, still under the 52.38% needed at −110.
Why the dial says about 3.3, not 4.3
The College Football Spread Dial fits home field as its own factor, alongside a power rating. In its September 2026 fit home field is worth 3.32 points; the page prints the current value every time it refits.
The raw 4.3 includes something besides home field: in college, the home team is often the better team. Stronger programs host more games, including the games they pay smaller programs to play at their stadium. Before kickoff, the home team was rated higher in 52.7% of these games, by 24 Elo points on average. At the dial's fitted rate that is worth about one point, which is the gap between 4.3 and 3.3. The dial counts team strength once, in the rating, and home field once, in its own factor.
