Break-even win rate at −115
The implied probability of −115 is about 53.49% (1 ÷ the exact decimal odds, shown rounded). That is the break-even win rate: if you bet this price many times on win-or-lose bets, you need to win more often than that to come out ahead. Whether a −115 bet is good value depends only on whether your honest estimate of the chance beats that number — the EV calculator does the comparison.
−115 is a common price on spreads and totals. When both sides of a two-way market are −115, the implied probabilities add up to 106.98%: the extra 6.98% is the bookmaker’s margin, and the fair price for each side is even money (+100). See the vig calculator for other markets.
−115 in a parlay
Two −115 legs parlayed combine to decimal odds of ≈ 3.50 (+250, rounded): a $100 two-leg parlay pays $349.53 if both win. Three legs: decimal ≈ 6.53 (+553, rounded), paying $653.46 on $100. For independent selections from different events, those prices imply a break-even chance of about 15.30% for all three winning — an implied figure that includes each price’s margin, not a forecast; bookmakers may refuse or reprice related selections. Payouts use the exact, unrounded combined odds. Build your own with the parlay calculator.
