Baseball Betting Odds: Break Even Percentages

The probability necessary to win at a given spread is not always something the novice gambler is aware of. This is important because novice gamblers get tempted to bet on the -200 favorite because he/she knows it will likely win the game. What they don’t know is that if the given -200 favorite does not have a 66.6% or better chance of winning, it is a losing proposition over the long haul.

How To Calculate Baseball Betting Odds For Favorites

I define a favorite as a team with a negative spread like -105, -150, etc.

Take the absolute value of the spread and divide by itself plus 100. For example, for an -150 team, take 150/250 = 60%. To pull even, our -150 favorite must win 60% of the time.

How To Calculate Baseball Underdogs Betting Odds

Take 100 and divide by 100 plus the spread. For example, a +150 team, take 100/250 = 40%. To pull even, our +150 dog must win 40% of the time.

Being able to predict a team’s probability of winning is equally as important when you want to win betting baseball.
