Is −105 good odds?
It depends on how likely the bet is to win, not on the number itself. −105 is a good price on a side that wins more than 51.22% of the time and a bad one on a side that wins less. If a market kept nothing, the other side of a −105 bet would be +105; real books price it worse than that, and the gap is their cut. At −110 on both sides, the most common spread and total price, the cut is 4.76%. Which book keeps the least differs: every sportsbook's cut, measured.
As a price, −105 makes the side close to even: at this price both sides of a game are often priced alike, and the gap from 50% is mostly the book's cut.
What a better price is worth
Find −104 instead of −105 on the same bet and the win rate you need drops from 51.22% to 50.98%. Over 100 bets of $100 that win 51.22% of the time, −105 breaks even and −104 comes out about $46.90 ahead: the same picks, a better price. Books often differ by that much on the same game: the board shows which one pays the most.
