The typical range for the vig, or vigorish, on standard sports bets usually falls between 4.5% and 10%. For point spread and over/under bets, sportsbooks often set the odds at -110, which equates to a vig of about 4.55%, meaning bettors are paying a premium on both sides of the wager. In some cases, particularly in more competitive markets or high-stakes games, the vig can be slightly lower or higher depending on the betting volume and sportsbook strategy.
