Convert betting odds into implied probability, compare market prices, and see what probability a bookmaker price implies.
Implied probability converts betting odds into a percentage chance. It helps you read a price before judging whether the market is too short, too high, or close to fair.
Enter one price and calculate the percentage chance suggested by those odds.
Use this section for two-way or three-way markets where the listed prices include bookmaker margin.
Implied probability is the chance suggested by a betting price. It turns odds into a percentage, which makes the market easier to compare with your own estimate.
Divide 1 by the decimal odds and multiply by 100. Decimal odds of 2.50 imply 40% because 1 ÷ 2.50 × 100 equals 40%.
Bookmaker prices usually include margin. When the implied probabilities of all outcomes are added together, the total often exceeds 100%.
No-vig probability removes the market margin proportionally from the listed prices. It gives a cleaner estimate of how the market prices each outcome before margin.
No. It only shows what the price implies. A bet becomes interesting only when your own estimated probability is higher than the market’s implied probability by enough to justify the risk.
