Margin & no-vig fair odds

Enter every outcome of a market in decimal odds to see the bookmaker's margin and what the odds would be without it.

Bookmaker margin 4.71%
Implied probabilities sum to 104.71%. Everything above 100% is the book's edge — the no-vig column strips it out proportionally to show the market's true price.

How odds conversion works

Decimal odds

Decimal odds show your total return per unit staked, stake included. At 2.50, a 100 stake returns 250 — a 150 profit. It is the cleanest format to compute with, which is why every formula below routes through it.

Fractional odds

Fractional odds show profit relative to stake. 3/2 means you win 3 for every 2 staked. Convert with decimal = numerator / denominator + 1, and back with fraction = decimal − 1, expressed as a ratio. 1/1 is "evens" — a 2.00 decimal, a 50% implied probability.

American (moneyline) odds

A positive number is the profit on a 100 stake; a negative number is the stake needed to win 100. Converting from decimal: if decimal ≥ 2.00, american = (decimal − 1) × 100; if decimal < 2.00, american = −100 / (decimal − 1). So the standard −110 juice is 1.9091 in decimal.

Implied probability

implied probability = 100 / decimal. It is the win rate the bet needs just to break even. A −110 line implies 52.38% — bet it at a true 50% chance and you lose money over time. Going the other way, decimal = 100 / probability%.

Hong Kong, Indonesian and Malay odds

Hong Kong odds are simply decimal − 1 — profit per unit staked, always positive. Indonesian odds behave like American odds divided by 100: decimal − 1 when the decimal is 2.00 or above, otherwise −1 / (decimal − 1). Malay odds invert that convention: positive up to 2.00 (decimal − 1), negative above it (−1 / (decimal − 1)), so a favourite reads positive and an underdog reads negative.

Bookmaker margin (the vig)

Add up the implied probability of every outcome in a market. A fair market sums to exactly 100%; a real one sums to more, and the excess is the operator's margin: margin = (Σ 1/decimalᵢ − 1) × 100. Two sides priced at 1.91 imply 52.36% each — 104.71% total, a 4.71% margin.

No-vig fair odds

Removing the margin proportionally gives each outcome's fair probability: fair pᵢ = pᵢ / Σp, and fair odds = 1 / fair pᵢ. It's the fastest way to read what a book actually thinks a result is worth, and to compare that estimate against another book's price.
