Hold Calculator

What hold measures

Hold — also called vig, juice, or overround — is how much a bookmaker builds into a market above a fair 100%. Add up the implied probability of every side and the amount over 100% is the hold. A -110 / -110 two-way market holds about 4.76%; a tight market holds less, a soft or three-way market often holds more. Lower hold means more of your money is in play and less is the book's cut, so hold is a quick read on how sharp a book's price is.

How to use it

Enter side A and side B for a normal two-way market. For a three-way line like soccer 1X2, fill in the draw as side C too. The calculator sums the implied probabilities and shows the hold plus each side's number. To turn a market's prices into the fair, no-vig line for one side, use the No-Vig Calculator; to compare which books hold least across a live slate, see the prediction markets vs sportsbooks breakdown.
