What does -110 mean?
You often see -110 next to the point spread for a game. These numbers are the payoff odds. They mean you need to wager $110 to be paid $100 for a win.
-110 can also be calculated as a fractional payout of 10/11, or $90.91, which means that a winning bet of $100.00 will pay $91.91. Put another way, your winning bet will pay you at $100 for every $110 wagered—or 91.91% on each dollar. So, including your wager of $100 your total payout will be $191.91.
