Want to know the Equation for Huge wins? Maths + Luck ÷ Money = Accumulators
We’ve all done it right? Placing an accumulator bet was part of my Saturday ritual, nipping down to the bookies on my first break of my DIY job whilst trying to pay my way through further education and picking about ten teams to win at odds of around 5000/1.
Unfortunately, I had to keep that Saturday job all the way through education as I never did win, but that is not to say some people do not, as some huge accumulator pay outs have been recorded over the years.
But what exactly are ‘acca’s’ and how are the odds calculated? We decided to dig deep into the popularity and maths behind one of betting’s most popular forms.
Apologies to those that are familiar with accumulators but to put it simply, an accumulator is a single bet that links a number of other bets which requires each bet to be a winner in order to pay out.
Most commonly used in football, accumulators are a way to significantly increase your odds as there is more than one team involved and that must win in order for it to be a success.
Naturally ‘Acca’s’ are not just reserved for football and multiple book makers offer certain accumulator promotions such as Ladbrokes five team acca insurance which means if you back five teams to win but one lets you down, they will return your initial stake (terms and conditions apply).
The potential wins are also huge as the more games you accumulate into your single bet, the larger the odds become but the less likely a pay-out is.
Pay-outs do happen though, just ask a bored mother who took home a whopping £600,000 on a 12-team accumulator, according to Casinopedia – she put on just because she liked the name of the teams.
But how do the maths work?
The Mathematics bit
We have all heard the stories of people racking up huge wins like the story above after betting only a couple of quid but how is it calculated?
An accumulator is often classed as four or more selections with the upper reaches limitless in your bid to increase the odds, but most book makers offer a double and treble selection on their betslips but for our calculation example we are going to look at a four-fold acca.
The simple way to calculate a four-fold accumulator (meaning all four selections must win in order to receive a pay-out) is to convert all of the odds from your selected matches in to decimal odds then multiply them together to get your set odds.
For example, backing four teams who have fractional odds of 1/1 (Evens) is known as 2.0 in decimal terms.
Take those four 2.0 individual prices and multiply them (2.0 x 2.0 x 2.0 x 2.0) and you get a sum total of 16/1 on your selection.
That means a £10 bet will win you £160 plus your stake if all four bets come in.
