Double Chance Odds and Return Formula

A double chance bet covers two of the three possible match outcomes (commonly written as 1X, X2, or 12). If you have 1X2 decimal odds for Team1 win (O1), Draw (D), and Team2 win (O2), you can estimate the implied (fair) double chance decimal odds by converting each 1X2 odd to an implied probability (1/odd), removing the 1X2 market’s overround via normalization, summing the two selected outcome probabilities, then inverting.

O_DC = (1 / O1 + 1 / D + 1 / O2) / (1 / Oa + 1 / Ob)
R = S × O_DC

Variables:

  • ODC is the estimated double chance decimal odds for the selected double chance (1X, X2, or 12)
  • R is the total return from the double chance bet (stake included)
  • S is the stake
  • O1 is the Team1 win decimal odds (from the 1X2 market)
  • D is the draw decimal odds (from the 1X2 market)
  • O2 is the Team2 win decimal odds (from the 1X2 market)
  • Oa and Ob are the two selected outcomes’ odds for the chosen double chance (for example, for 1X then Oa=O1 and Ob=D)

To estimate the double chance odds, compute the implied probabilities 1/O1, 1/D, and 1/O2, then use the formula above for the two-outcome double chance you selected. To get the total return for a stake, multiply the stake by the estimated double chance odds. (Note: actual bookmaker double-chance prices can differ because they may apply a different margin to double-chance markets.)

What is a Double Chance Bet?

A double chance bet is a type of wager (common in soccer/football) that covers two of the three possible outcomes in a match with a single bet: 1X (Team1 win or Draw), X2 (Draw or Team2 win), or 12 (Team1 win or Team2 win). If either of the two outcomes you selected occurs, the bet wins; otherwise, it loses. Double chance bets increase the probability of winning compared to a single-outcome bet, but they typically come with lower odds (and therefore lower potential payout) than betting on just one outcome.

How to Calculate Double Chance Bet?

The following steps outline how to calculate a double chance bet’s estimated odds and total return.

  1. Choose the double chance type: 1X (Team1 or Draw), X2 (Draw or Team2), or 12 (Team1 or Team2).
  2. Determine the stake (S).
  3. Determine the 1X2 market decimal odds: Team1 win (O1), Draw (D), and Team2 win (O2).
  4. Convert each 1X2 odd to an implied probability: p1=1/O1, pX=1/D, p2=1/O2, and compute the overround T=p1+pX+p2.
  5. Sum the implied probabilities of the two outcomes included in your double chance, then estimate double chance odds with ODC = T / (sum of included implied probabilities).
  6. Calculate total return (stake included): R = S × ODC.
  7. After inserting the values and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge (decimal odds).

Stake (S) = $100

Team1 Win Odds (O1) = 2.5

Draw Odds (D) = 3.0

Team2 Win Odds (O2) = 2.8

For a 1X double chance (Team1 or Draw), the estimated double chance odds are:

O1X = (1/2.5 + 1/3.0 + 1/2.8) / (1/2.5 + 1/3.0) ≈ 1.4862

Total return (stake included) ≈ $100 × 1.4862 = $148.62
