Break-even win rate at 9/2
The implied probability of 9/2 is about 18.18% (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 9/2 bet is good value depends only on whether your honest estimate of the chance beats that number — the EV calculator does the comparison.
9/2 in a double or treble
A double of two 9/2 selections combines to decimal odds of 30.25 (+2925): a £100 double pays £3,025.00 if both win. A treble: decimal ≈ 166.38 (+16538, rounded), paying £16,637.50 on £100. For independent selections from different events, those prices imply a break-even chance of about 0.60% 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 accumulator calculator.
