What is a Double Bet?

A multiple bet consisting of two selections, both of which must win to gain a return.

Coxless Double Rowing

The double is a bet where two selections are made and if the first wins, everything that would have been returned is then used as stake for second. This style of bet is popular because it creates the potential for larger returns but at the expense of increased risk as all it takes is one losing selection for the bet to return nothing. Similar to the treble and accumulator the only difference being a lower number of selections. Each way and to-place only options are also available at some bookmakers.

Popular in all sports especially football and horse racing, all bets in a double must be on separate events.


Once familiar with the examples, use the double calculator to quickly work out winnings. The accumulator calculator can also be used to experiment with more than 2 selections.

The football scores in the table below are used to demonstrate winnings and losing example bets:

Home Team Score Away Team
Sunderland3 - 1Fulham
QPR4 - 2Chelsea


Assuming a unit stake of £5 on Sunderland to win at odds 2/1 and QPR to win at odds of 3/1 the winnings would break down as follows:

  • Returns = £5 * (2/1 + 1) * (3/1 + 1) = £60
  • Profit = Returns - Stake = £55


Assuming a unit stake of £5 on Sunderland to win at odds 2/1 and Chelsea to win at odds of 4/1 the returns would break down as follows:

  • The bet of Reading to win has lost, therefore this bet returns £0
  • Profit/Loss = Returns - Stake = -£5
