About

This Double Chance Bet Calculator is a precision tool for sports traders and bettors who wish to cover two out of three possible outcomes in a match (e.g., Home Win or Draw). While bookmakers offer explicit Double Chance markets, they often charge a higher "margin" (vig) on these bets compared to the standard Match Winner (1X2) market.

By using this tool, you can create your own Synthetic Double Chance bet by splitting your stake mathematically between two outcomes. This technique, often called Dutching, ensures that regardless of which of the two outcomes occurs, your profit remains identical. This tool calculates the exact stake distribution required for 1X (Home/Draw), X2 (Draw/Away), and 12 (Home/Away) based on the raw odds.

Why use this? Often, the synthetic odds calculated here (Osyn) are higher than the Double Chance odds offered by the bookie, presenting a value betting opportunity.

Formulas

The synthetic odds Osyn are derived from the harmonic mean of the individual probabilities. If you want to cover Outcome A (with odds OA) and Outcome B (with odds OB):

Osyn = 11OA + 1OB = OA × OBOA + OB

To calculate the stake required for Outcome A (SA) given a Total Stake Stotal:

SA = Stotal × OsynOA

Frequently Asked Questions

Bookmakers often apply a higher margin (the "vigorish") to Double Chance markets because they are convenient. By placing two separate bets on the individual outcomes (e.g., Home and Draw) using the stakes calculated here, you often get better effective odds and higher returns for the exact same coverage.
Dutching is the process of splitting your total stake across multiple selections so that the profit is the same regardless of which selection wins. This calculator automates the math to ensure your returns are balanced perfectly between the two outcomes you want to cover.
If the calculated synthetic odds are less than 1.00, it means the combined probability of the two outcomes is greater than 100% in the bookmaker's model (or the odds are extremely low). This guarantees a loss. This usually only happens if you input incorrect odds or if the bookmaker's margin is exceptionally high.
