Is +300 good odds?
It depends on how likely the bet is to win, not on the number itself. +300 is a good price on a side that wins more than 25.00% of the time and a bad one on a side that wins less. If a market kept nothing, the other side of a +300 bet would be −300; 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, +300 makes the side a big underdog.
What a better price is worth
Find +310 instead of +300 on the same bet and the win rate you need drops from 25.00% to 24.39%. Over 100 bets of $100 that win 25.00% of the time, +300 breaks even and +310 comes out about $250.00 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.
