A treble bet is another name for an accumulator bet that only has 3 selections. All 3 selections must win for the bet to win.

Larger returns can be had from placing treble bets like any accumulator bet at the exchange of a higher risk of the bet losing. All bets in a treble must be placed on different events. The odds of the individual selections are multiplied together to give us a total odds for the treble.


You can use the simple treble calculator below to calculate your return on a treble bet.

Here is an example using football games.

Home Team Score Away Team Odds (decimal in brackets)
Manchester Utd 2 – 0 Manchester City 2/1 (3.0)
Arsenal 4 – 1 Chelsea 5/2 (3.5)
Sunderland 1 – 0 Newcastle 4/1 (5.0)

If we had selected all the home teams to win then our treble would have been a winner.

If we had placed a £10 bet on this we would calculate our return in the following way. Using the decimal odds:

  • £10 x (3.0 x 3.5 x 5.0) = £525

So that would be £515 profit on a £10 bet for choosing 3 correct results!

Obviously if any one of the our selections had lost then the treble bet would lose and we would lose our £10 stake.
