Break-even and long-run results

The implied probability of -700 is 87.50%, and that number is also the break-even win rate: win more often than 87.50% of the time at this price and you profit in the long run, win less often and you lose. The table shows the return on stake at a few win rates, including the break-even rate itself.

At 87.50% this is a heavy favourite. Prices this short appear when one side is expected to win comfortably: a top seed against a qualifier, a strong home team against a relegation candidate, or a moneyline in a game with a double-digit spread. The catch is the payout. You need to win more than 87.50% of these bets just to stand still, and one loss wipes out several wins.

The vig at -700

If both sides of a two-way market were priced at -700, the implied probabilities would add up to 75.00% above 100%. That excess is the overround, or vig; as a share of stakes it is a 42.86% margin for the bookmaker. Removing it leaves fair odds of 2.00 decimal ( +100) on each side. Use the devig calculator to do the same for any market.
