Definition
Floor means the reliable low-end outcome a player, team, or bet is expected to produce. In sports betting and DFS, it describes how bad the result can be before the play becomes unacceptable. A high-floor player has stable usage, minutes, touches, or matchup factors that make a total collapse less likely. A low-floor play depends more on spikes, touchdowns, long shots, or unusual game flow.
There is no fixed betting formula for floor. It is an input to projection work, not a payout equation.
Worked Example
A running back is projected for 16 carries and 4 targets. If his low-end projection is 62 rushing yards, 3 catches, and 18 receiving yards, his PPR floor is:
6.2 rushing points + 3 reception points + 1.8 receiving points = 11.0 fantasy points
If his DFS salary requires about 12 points to stay competitive in cash contests, that floor is close to the needed baseline. A boom-or-bust receiver projected for 4 targets might have a 3-point floor even with a higher ceiling.
Why It Matters
Floor helps a bettor avoid plays that need too many things to go right. It is most useful when comparing props, DFS cash plays, and conservative portfolio choices where avoiding a poor result matters as much as chasing upside.
