What is Hold?

Hold (also called overround or margin) is the percentage of total wagers a sportsbook expects to keep as profit. It is calculated from the difference between the sum of implied probabilities and 100%. Standard -110/-110 lines have a 4.55% hold.

Lower hold = better value for bettors. Shopping lines across multiple books helps you find lower hold markets.
