## What is Hold in Sports Betting?

In sports betting, hold is the percentage of money wagered that sportsbooks keep for themselves. A larger hold percentage typically means worse odds for you as the bettor.

## How to Calculate Hold in Sports Betting

The true odds for an outcome, such as which team will win, add up to 100%. However, if you convert a sportsbook's odds to implied probabilities, you'll see that the total is greater than 100%. This is because sportsbooks charge a vig (juice, tax, etc.) on all their markets to help ensure they make a profit.

Hold is calculated by converting odds into implied probabilities, adding together the implied probabilities, and subtracting 100%.

For example, let's say the Boston Celtics are -180 favorites against the +150 Los Angeles Lakers. -180 American odds converts to a 64.29% implied probability and +150 converts to a 40% implied probability. Adding these implied probabilities together, we get 104.29%. If we subtract 100% from this, we get a 4.29% hold.
