Sports Betting – How Odds Are Calculated


Betting is one of the most affordable hobbies that can deliver plenty of entertainment value, especially on days when you make a correct pick. While other hobbies like bowling require a lot of money and consume your time, betting is relatively inexpensive and easy to engage in at home or on the go. It is also convenient, as you can enjoy it anywhere, including your favourite bar or restaurant.

Bettor’s odds

Odds are a measure of the probability that a particular team or individual will win a game. They are calculated by putting together the probability that the event will happen, plus the amount of money that must be paid out to all bettors (the vig).

A bettor’s goal is to find betting opportunities where the odds are in their favor. This is known as value betting and is the key to long-term profitability in sports betting. Identifying the best bets requires knowledge of a sport’s rules and strategy, as well as an understanding of how odds are calculated.

Popular teams tend to receive outsized attention from the media and public, which can force bookmakers to shade their lines toward them. This creates an opportunity for contrarian bettors to find +EV plays on underdogs as the crowd fawns over their favorites. In addition, bettors can place wagers on totals, or “over/under” wagers, which are bets that predict the combined number of points scored in a game. The over/under line is set by a bookmaker and can be changed in real-time.
