Bet Calculators Explained

A bet calculator is another innovation brought on by the modern era of online sports betting. Simply put, it is an app or program which allows punters to quickly calculate the potential winnings before they make a bet. Other calculators also allow you to things like implied chances. These calculations are based on the betting odds the bookie offers, the type of bet, and the size of your stake.

If you’re wondering how to use a bet calculator, you don’t have to worry, they’re almost always simple and user-friendly (If not, you should probably try to find a new one.) Simply type in your bet type, the number of selections in question, and the size of your stake. Other options often include options for different odds formats (decimal, fractional, or US Moneyline), whether your bet is each-way or not, and whether rule 4 is applicable or not. Just to be clear, Rule 4 is sometimes used in horse betting to adjust the winnings in cases where a horse is withdrawn before the beginning of the race.

You can find a large number of different calculators online. These days a lot of top online bookmakers have started offering it right on their betting sites. This can save you some time, but we’ve found that the best bet calculators are offered by independent sites. In the end, however, you can do a bit of research and figure out which one suits your needs best.

Betting Calculator – Types of Bets

If you’re a newbie to sports betting, you must be thinking – why are these even needed? Most online bookies calculate your potential winnings right there on the bet slip. Well, things get a bit more complicated if you’re using combination bets. While yes, common types like accumulators can have their returns calculated right on the betting site, there are other types which take a bit more math.

Bet calculators can make your life easier with regular singles, doubles, or Accas – in case you, for example, aren’t using an online bookie to place your bet and are instead at a brick-and-mortar betting shop. Otherwise, they can be used for planning out potential bets and trying to find value. There are also these so-called combination bets, which would be annoying to figure out without a calculator.

Combination betting is a practice which involves placing multiple bets on a series of selections. The goal here can be either to reduce risk or maximize potential profits. These types of bets are sometimes also referred to as selection bets or multiples (Be careful, however: depending on where you are in the world, multiples can also be used to refer to accumulators.)

Sometimes, though, combination bets can be used to just make things more interesting. That’s why they are a widespread betting offer with horse racing, which has only a few possible markets for a single bet. However, they can be made regardless of available markets, meaning combination bets are a viable option for football betting, basketball betting, or whichever other sport or niche you prefer.

Unlike an accumulator, a combination bet does not depend on the success of all of its constituent bets. If a single part or 'leg' of a combination bet fails – others can still possibly succeed.

We’ll start explaining these with a simple example. Let’s say you’re doing some Grand National betting and want to bet £15. You can decide to just put them all up on a single horse in a single race. If the horse doesn’t win, you just lose your entire stake.

You could, on the other hand, split it into 3 horses over 3 races with a £5 stake each. That way, you have much better chances of at least one of these winning. This added safety is the main advantage of this type of betting. However, splitting your stakes also makes it much less likely that all of these separate bets will win, reducing potential profits.

In fact, with combined bets, the results are no longer a binary ‘win’ or ‘lose. You have a whole scale of possible successes and failures, depending on how many individual selections succeed.

Types of Combination Bets

Over the years, punters have thought of a lot of different kinds of combinations. The simplest ones we explained above – but then you have combination bets made of smaller combination bets. Theoretically, there is no limit to how many individual bets you can select and how you combine them, but there are some combinations which have become standardised, such as Trixie, Yankee, or Lucky 15. You've probably heard of these before, and here we'll list and provide a summary for each type.

These are all of the different betting types you are likely to see on a typical bet calculator. Again, some betting sites may have different offers, and we can't account for all of them, but these should be familiar to any punter.

Do note that each type also has a dedicated page right here on BettingFellow. Simply follow the corresponding link to find out more details about each type of combination bet.

Double Bet

A type of bet which you make two selections and if the first wins, everything that would have been returned is then used as a stake for the second. This type works more like an accumulator than a typical combination bet, meaning that if either selection loses – you lose the whole double. Still, it’s important to understand it as a concept because many of the more complicated multiples use doubles as building blocks. Double Bet Calculator


A treble works much like the double, only it is comprised of three individual selections. Again, if any of these selections fail, the whole bet also fails, meaning a treble works much like a 3-leg accumulator. Just like a double bet, this is not a selection wager in the usual sense but is important to understand. Treble Calculator


Because Accas are quite often parts of combination bets, we’ll include a brief explanation here as well. An accumulator, also often called parley or Acca is a bet made up of several individual bets, or "legs". All of them need to win for the accumulator bet to succeed. It can consist of anywhere between 2 and 10 bets. This means that the riskiness of such bets increased exponentially, but so does the potential profit. As noted above, accumulators with 2 and 3 legs are called doubles and trebles. Those with 4, 5, 6, or more legs are called four-fold, five-fold, six-fold, and so on. Accas have their own set of characteristics which we won’t be discussing here – we’re just making sure you understand the concept. 


The smallest type of “true” combination bet, and thus the easiest to understand. It consists of 4 bets: 3 doubles and a treble. As we discussed previously, the success of either one of these is not dependant on the success of the others. You need at least one of the doubles to win s othat you can have your stake back. Two wins or more, however, mean that you already have a profit. Statistically speaking, that’s pretty good – so it should be easy to see the value of this type of betting. Trixie bets are great if you’re new to combination bets and want something that spreads you stake evenly, and is easy to understand and keep track of your bets. Trixie Bet Calculator


Next up we have Patent bets, which consist of 7 individual selections: 3 singles, 3 doubles, and a treble. A Patent bet is essentially the same as a Trixie, only you further spread your stake with the added singles. Note that this does not require more individual matches or selections – it still only uses three. The doubles are simply various combinations of the singles, and the treble unifies them all as an accumulator. Seeing how your stake is spread even further, Patents are valued for their increased chances of generating a return. However, those returns can be small on their own, especially in the case of singles. The “you need two wins to make a profit” no longer applies here. Patent Bet Calculator


The next combination bet which adds a fourth selection. This complicates things a lot more than it might seem at first glance – a Yankee bet consists of 11 separate bets: 6 doubles, 4 trebles and a four-fold accumulator. How many of these you need to get a return depends on the individual odds and varies on a case-by-case basis. Generally speaking, you need a larger stake to reasonably make use of a Yankee compared to a Trixie. Yankee Bet Calculator

Lucky 15

A Lucky 15 relates to a Yankee bet the same way a Patent is similar to a Trixie. It maintains the same core of 4 individual selections but also plays each of them as a single. Thus, a Lucky 15 bet consists of 4 singles, 6 doubles, 4 trebles and a four-fold accumulator. You will notice that this is a sort of trend with combination bets – there’s almost always a version with singles and a version without them. Lucky 15 bet calculator

Canadian / Super Yankee

Both of these names are used to designate essentially the same thing: a combination bet consisting of 5 individual selections. These are combined into 26 bets: 10 doubles, 10 trebles, 5 four-fold accumulators and one five-fold accumulator. The value of bet calculators should be fairly apparent at this point: calculating the implied probabilities and potential profits for bets such as these would be a nightmare. With a calculator, you can simply type in the individual selections’ odds and their results, and let the software do the rest. Canadian Bet Calculator

Lucky 31

Very similar to a Canadian, only the five individual selections are also wagered as singles. This brings the total bets to 31 (hence the name): 5 singles, 10 doubles, 10 trebles, 5 four-folds and a five-fold accumulator. Note that the order in which bets appear on the slip is not important because each of the 5 selections appear the same amount of times across all 31 bets. Lucky 31 Bet Calculator


the next on the ladder of progressively broadening combination bets is the Heinz with 6 individual selections. The bets continue to exponentially grow in number, with Heinz consisting of 57 bets: 15 doubles, 20 trebles, 15 four-folds, 6 five-folds and a 1 six-fold accumulator. A Heinz requires two of the selections to win to guarantee a profit. Heinz Bet Calculator

Lucky 63

The version of Heinz where the selections are also played as singles. This amounts to a whopping 63 individual bets: 6 singles, 15 doubles, 20 trebles, 15 four-folds, 6 five-folds and a six-fold accumulator. Often the target of various bonuses depending on the scenario. For example, “all winners” or “one loser” may include a percentage increase to the reward. Lucky 63 bet calculator

Super Heinz

As you might imagine, this combination takes it a step further with 7 individual selections. A Heinz bet consists of 21 doubles, 35 trebles, 35 four-folds, 21 five-folds, 7 six-folds and a seven-fold accumulator, bringing it to a total of 120 bets.

Super Heinz with Singles

This time around, there is no “Lucky 127”. As the name might imply, it’s a Super Heinz with singles included: 7 singles, 21 doubles, 35 trebles, 35 four-folds, 21 five-folds, 7 six-folds and a seven-fold accumulator, for a total of 127 individual bets. Super Heinz Calculator


The next logical step with 8 selections. The name is deserved, considering this is the biggest combination bet you can make. A Goliath bet consists of 247 separate bets: 28 doubles, 56 trebles, 70 four-folds, 56 five-folds, 28 six-folds, 8 seven-folds and an eight-fold accumulator. Goliath Bet Calculator

Super Goliath

Goliath bets are often criticised for their lack of singles, and this rare type attempts to solve that problem. A Super Goliath is often referred to simply as a Goliath With Singles. This bet is made up of 255 separate bets: 8 singles, 28 doubles, 56 trebles, 70 four-fold accumulators, 56 five-folds, 28 six-folds, 8 seven-folds and an eight-fold accumulator. Super Goliath Bet Calculator

Each Way Betting

Matters are further complicated by the fact that each of these can also be considered Each Way. This is specific to horse racing but is useful to know, seeing how most of these combinations are used almost exclusively for this sport. We recommend reading through Betting Fellow’s article on Each Way betting to find out more.
