Break-even win rate at −110

The implied probability of −110 is about 52.38% (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 −110 bet is good value depends only on whether your honest estimate of the chance beats that number — the EV calculator does the comparison.

−110 is a common price on spreads and totals. When both sides of a two-way market are −110, the implied probabilities add up to 104.76%: the extra 4.76% is the bookmaker’s margin, and the fair price for each side is even money (+100). See the vig calculator for other markets.

−110 in a parlay

Two −110 legs parlayed combine to decimal odds of ≈ 3.64 (+264, rounded): a $100 two-leg parlay pays $364.46 if both win. Three legs: decimal ≈ 6.96 (+596, rounded), paying $695.79 on $100. For independent selections from different events, those prices imply a break-even chance of about 14.37% 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.
