How to use Bet Calculators

First, you should select the type of bet you want. This could be a simple ‘win bet’: where you choose and back a winner in one event. If you place several win bets for different events, this is called ‘multiple bets’.

You can substantially increase your winnings by placing single, double, or triple win bets across several events. But remember a payout requires all your predictions to come in, e.g. a double needs two correct predictions to secure a win.

Betting on four or more events is called an accumulator. Correct predictions on this scale can earn larger payouts from smaller stakes.

Once you understand win bets, you could explore full cover bets. The advantage here is you can win a payout even if some of your predictions weren’t correct.

You will know betting odds can be displayed in different formats. And if you’re a novice, it’s worth taking the time to understand the odds shown in different formats. However, you can also use our odds converter to see all quoted odds in your preferred format.

Non-Runner Acca

If one selection doesn’t play or you pick a non-running horse the accumulator is reduced i.e. a six-fold would become a five-fold.

Accumulators are available in all sports, but, bookmakers vary in their rules on combining selections from more than one to create a single bet. Selections from the same event cannot be combined into a single accumulator, this is to deter anyone from trying to place several bets on the same selection.

There is also the option to place permutations on accas, e.g 4 from 6 or 5 from 6 and so on. Please see the types of bets below.

Another way is to find a bookmaker who offers acca insurance

The difference and advantage of this method are that it gives the punter the option to arrange their selections so that the more fancied selections have a greater effect on the winnings. The favoured approach is to place fancied choices in positions 2, 3, 4, and 5, leaving 1 and 6 for the least favourite as these are not included in the Yankee.

Only one selection needs to win to gain a return. Very popular with horse racing punters, though this wager is possible for every sport. Use the free bet calculator to work out potential odds and returns and use the odds converter to see fractional, decimal, and American or Money Line Odds.

Fixed percentage bonuses are sometimes given by UK Bookmakers in cases where all selections are winners. For example, if the returns from the bet were £200 and all selections had won, a bonus of 10% would return £220.
