An accumulator bet is a selection of two or more bets combined into one, these type of bets give much higher odds than that of a single bet, this makes accumulators highly attractive to the better, but, your chances of winning are a lot less due to the increased risk, all it takes is for one bet to lose for the entire accumulator to lose. Should your accumulator win though, your winnings can multiply dramatically compared to that of a single bet.
There are different types of accumulator bets, I have laid these out in the table below:
Accumulator table
There is no limit to the amount of bets that can be be placed on one Accumulator, and the odds can be staggering because of the risk involved, but they are most definitely not impossible. It was reported in 2017 that a housewife had placed a TwelveFold Accumulator on a football bet and won a massive £574,278, and she isn’t the only one to have won big this way.

Winning and Losing Examples
I have laid out some examples below of winning and losing accumulators.
You can also use the ‘Accumulator calculator’ to help do the maths for you.
Winning Example
Consider the following 4fold football accumulator.
Match Result  Selection  Odds (Decimal)  Bet Outcome 

Celtic 1 – 0 Aberdeen  Celtic To Win  1.5  Successful 
Blackburn 2 – 1 Shrewsbury  Shrewsbury To Lose  1.4  Successful 
Chelsea 1 – 1 Burnley  Chelsea To Draw  3  Successful 
Everton 0 – 0 Liverpool  Liverpool To Draw  5  Successful 
Assuming you place a bet of £5 the calculation using decimal odds is as follows:
 Total Returns = £5 * 1.5 * 1.4 * 3 * 5 = £145
 Total Profit = Total Returns – Initial Stake = £150
The equivalent calculation using fraction odds would be:
 Total Returns = £5 * (1/2 + 1) * (2/5 + 1) * (2/1 + 1) * (4/1 + 1) = £145
Losing Example
If any of the above selections fail to win, the whole stake is lost. For instance in the example above if Celtic had failed to beat Aberdeen, the “Celtic To Win” selection would have lost and hence so would your accumulator, resulting in an overall loss of £5.
Each Way Example
An each way accumulator bet consists of two parts:
 A standard towin accumulator bet as outlined in the examples above.
 An accumulator bet on each of the selections you chose ‘toplace’, with the “Selections” and “Odds” updated accordingly. Note that a toplace option may not be available for all sports and events.
A unit stake is placed on each of the 2 parts with the returns pooled to reach the total returns for the wager.
Have a look at the following horse race accumulator below:
Selection  Odds (Fractions)  To Place  Bet Outcome 

1  4/1  1/5  Won 
2  9/1  1/5  Won 
3  3/1  1/5  Placed (came 2nd) 
4  10/1  1/5  Won 
Assuming a unit stake of £5 the returns would break down as follows:
 The towin part of the bet would lose because selection 3 failed to win, resulting in loss of the £5 stake and £0 returns.
 Your toplace part would be calculated as shown:

 Part 2 Returns = £5 * ( ( 4 * 1/5 ) + 1 ) * ( ( 9 * 1/5 ) + 1 ) * ( ( 3 * 1/5 ) + 1 ) * ( ( 10 * 1/5 ) + 1 ) = £120.96
 Part 2 Profit = Total Returns – Unit Stake = £115.96
The total returns for your bet is the result of adding together the returns from the 2 parts.
 Total Returns = £120.96 + £0 = £120.96
 Total Profit = Total Returns minus the 2 £5 stakes = £110.96
There are so many variations of bets available from the bookmakers. I have compiled a table of these bets along with a short description of their rules: ‘Different Types Of Bets’
