Is −800 good odds?
It depends on how likely the bet is to win, not on the number itself. −800 is a good price on a side that wins more than 88.89% of the time and a bad one on a side that wins less. If a market kept nothing, the other side of a −800 bet would be +800; 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, −800 makes the side a big favorite: one loss wipes out the profit of several wins.
What a better price is worth
Find −750 instead of −800 on the same bet and the win rate you need drops from 88.89% to 88.24%. Over 100 bets of $100 that win 88.89% of the time, −800 breaks even and −750 comes out about $74.07 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.
