What Is Overlay in DFS?
Last updated September 22, 2026 by Ship It Nation
Overlay happens when a guaranteed contest does not fill, so the entry fees collected fall short of the promised prize pool. The site pays the difference out of its own pocket.
Why It Matters
In an overlaid contest, the prize pool per entry is larger and the field is smaller than planned, which raises your expected value. It does not change how you build: it is simply a better price on the same contest. Large overlays are rare, so treat them as a bonus, not a plan.
Example
Say a $5 NHL tournament guarantees $10,000 in prizes, but only 1,700 entries come in by lock, which is $8,500 in fees. The site still pays the full $10,000, so the $1,500 gap is overlay. Everyone in that contest is playing for more prize money per entry than the contest was built to offer.
Check late-filling contests on smaller slates in the final minutes before lock. If entries are well short of the listed maximum, you may be getting a better price than usual.
Common Questions
How do you calculate overlay in DFS?
Multiply the entry fee by the number of entries, then subtract that total from the guaranteed prize pool. If the result is positive, that amount is overlay. For example, a $10,000 guarantee with $8,000 in entry fees has $2,000 of overlay.
Do only guaranteed contests have overlay?
Yes. A contest that is not guaranteed is usually canceled and refunded when it does not fill, so the site never has to cover a gap. Overlay only happens when the site has promised a prize pool regardless of how many entries come in.
Why is overlay so rare in big DFS contests?
Sites set guarantees they expect to fill, and big contests usually do. Many entries arrive in the final hours before lock, so a contest that looks short in the morning often fills by the time the slate starts.
