Break-even and long-run results
The implied probability of -360 is 78.26%, and that number is also the break-even win rate: win more often than 78.26% 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.
| Win rate | Return on stake |
|---|---|
| 50% | -36.1% |
| 55% | -29.7% |
| 60% | -23.3% |
| 65% | -16.9% |
| 78% | -0.3% |
At 78.26% 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 78.26% of these bets just to stand still, and one loss wipes out several wins.
The vig at -360
If both sides of a two-way market were priced at -360, the implied probabilities would add up to 56.52% above 100%. That excess is the overround, or vig; as a share of stakes it is a 36.11% 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.
