Is −270 good odds?
It depends on how likely the bet is to win, not on the number itself. −270 is a good price on a side that wins more than 72.97% of the time and a bad one on a side that wins less. If a market kept nothing, the other side of a −270 bet would be +270; 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, −270 makes the side a heavy favorite.
What a better price is worth
Find −265 instead of −270 on the same bet and the win rate you need drops from 72.97% to 72.60%. Over 100 bets of $100 that win 72.97% of the time, −270 breaks even and −265 comes out about $50.99 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.
