Break-even win rate at +150
The implied probability of +150 is about 40.00% (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 +150 bet is good value depends only on whether your honest estimate of the chance beats that number — the EV calculator does the comparison.
+150 in a parlay
Two +150 legs parlayed combine to decimal odds of 6.25 (+525): a $100 two-leg parlay pays $625.00 if both win. Three legs: decimal ≈ 15.63 (+1463, rounded), paying $1,562.50 on $100. For independent selections from different events, those prices imply a break-even chance of about 6.40% 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.
