Break-even win rate at −250

The implied probability of −250 is about 71.43% (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 −250 bet is good value depends only on whether your honest estimate of the chance beats that number — the EV calculator does the comparison.

−250 in a parlay

Two −250 legs parlayed combine to decimal odds of 1.96 (≈ −104, rounded): a $100 two-leg parlay pays $196.00 if both win. Three legs: decimal ≈ 2.74 (+174, rounded), paying $274.40 on $100. For independent selections from different events, those prices imply a break-even chance of about 36.44% 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.
