What is an Accumulator Bet? A Simple and Effective Way to Calculate Accumulator Odds

An accumulator bet (also called a parlay bet, multiple bet, or mix parlay) is a betting form where you combine multiple selections into one bet slip.
For this type of bookmaker online, it’s required that all your bets must WIN for you to collect any money.
It might sound risky, but actually, this type of bet can turn the tables for you, from losing to winning in just one wager. With a very small amount of money, you can win a large amount.
Of course, on the flip side, if one of your bets loses, you won’t receive any winnings.
Thus, accumulator betting can be seen as a “big game,” where you must accept high risks to gain big rewards. As long as you’re daring enough to get rich, you’ll have a chance to win big.
However, this does not mean that anyone can participate in accumulator betting. It is only suitable for those who have prior betting experience and deep knowledge of the sport they’re betting on to have a chance to win.

Some Types of Accumulator Bets You Should Know
There are many types of accumulator bets, depending on the number of matches and bets you want to place:

2 bets = Double

3 bets = Treble

4 bets = 4-Fold

5 bets = 5-Fold

6 bets = 6-Fold

How to Calculate Accumulator Bets
Before you place your bet, you need to select the odds format on the betting interface.
For this type of bet, it’s recommended to choose Decimal odds as it will show you the most straightforward information about the odds.

(1) How to calculate accumulator odds when all individual bets win
If all the bets in your accumulator win, you can calculate your potential payout using the formula:
Accumulator Odds = Bet 1 Odds x Bet 2 Odds x Bet 3 Odds x … x Bet n Odds
Example: If you have 3 bets (Chelsea, MU, and Liverpool) with odds of 2.16, 2.09, and 1.99, the accumulator odds will be 2.16 x 2.09 x 1.99 = 8.9837.
=> If you wager 100,000 VND on each unit, your total payout would be 898,370 VND.

(2) How to calculate accumulator odds for a draw/half win/half loss
If the outcome is a draw, half win, or half loss, the calculation becomes more complex, especially when dealing with Asian Handicap or Over/Under bets. Specifically:

If the outcome is a draw or void, replace the odds with 1.

If the outcome is a half-win, replace it with [1 + (odds – 1) / 2].

If the outcome is a half-loss, replace the odds with 1/2.
Thus, the formula for these cases is:
[Accumulator Odds = Winning Odds x (1 + (Half-Win Odds - 1) / 2) x 1/2 (if Half-Loss) x 1 (if Draw) …]

Example of Half Win/Half Loss Calculation:
If you place a 3-way accumulator bet with the following results:

Real Madrid 1 – 0 Fulham (Fulham -0.75) 1.90 - Half-Win

Barcelona 1 – 1 Liverpool (Over 2.25) 1.80 - Half-Loss

Stoke 0 – 0 Manchester United (Stoke +0.5) 1.95 - Win

Using this, your accumulator odds will be:
[1 + (1.90 - 1) / 2] x 1/2 x 1.95 = 1.4137
If you placed a 1,000,000 VND bet on each, your total payout would be 1,413,700 VND.

How to Bet Effectively and Safely on Accumulators
As mentioned earlier, accumulator betting is not for the faint-hearted; only those with experience and deep understanding of the sport have a higher chance of success.
Therefore, if you don’t have enough information about teams likely to win, it’s best to focus on teams with clear data and form. This increases your chances of winning.
For example, Manchester United, Liverpool, and Barcelona all have high win rates, but when they face each other, it’s impossible to predict which team will score more goals. In such cases, accumulator betting becomes riskier.
For new players, you can start with a simpler bet—like a 3-way bet (Asian Handicap, European Odds, and Over/Under for one match).
This allows you to focus your analysis on two teams within a single match, giving you clearer and more specific information to improve your chances of winning.
