What does -115 mean in betting?
-115 means you risk $115 to win $100, or $11.50 to win $10. The price says it wins 53.5% of the time, so you need to win more than 53.5% of your bets at -115 to make money.
In plain words
-115 is close to a coin flip with the book's cut built in. It usually sits across from -105 on the other side of a spread, a total or a player prop.
Add the two chances: 53.5% + 51.2% = 104.7%. The extra 4.7% is the book's cut, called the juice or the vig. It is why you need 53.5% at -115, not 50%, to break even.
This is where shopping for the price pays most. The same pick at -110 instead of -115 wins $3.95 more on every $100 bet that wins.
Where you see -115
A little extra juice. A spread or total at -115 on one side usually shows -105 on the other: the book is leaning, not moving the line.
