Double Bet Calculator
A Double combines two selections into a single bet where both must win for a return, with the odds multiplied together for a bigger payout than backing each one separately.
Bet Calculator
2 selections, both must win. 1 bet.
Enter valid odds for every selection (e.g. 5/1 or 6.0).
Figures shown are standard returns and don't include bookmaker-specific bonuses (e.g. some firms pay a bonus on a full Lucky 15/31/63 winning line, or double the odds on a Lucky 15 with a single winner). Always check your bookmaker's exact terms.
How It Works
Enter odds for both selections, set a stake, and mark each result as it comes in. Because both legs must win, the calculator shows you the combined odds first so you know the target return before either race is run.

Pro Tip
A Double only needs two winners rather than the three-plus required in a Treble or accumulator, so it is a good middle ground between the safety of a Single and the bigger prices of a longer multiple.
Frequently Asked Questions
What is a Double bet?
A Double is one bet made up of two selections. Both selections must win for the bet to pay out, with the odds of each multiplied together.
What happens if one selection in my Double is a non-runner?
A non-runner is voided, and the Double effectively reverts to a Single on the remaining selection at its original odds.
Are Doubles good value?
Doubles can offer strong value because the odds compound, but the risk is higher than a Single since both legs need to win. Many punters use Doubles on well-fancied horses across different races at the same meeting.
