What is a bet calculator?

Unless you’re a seasoned sports bettor, you may be confused about how you can work out your winnings and returns from a bet – either one you have won, or one that you hope to win. As you are interested in sport and winning money, you don’t really want to be bogged down in all the mathematics surrounding calculating your winnings and returns, in the same way you don’t personally have to calculate the overall cost of your shopping list depending on the individual items you have bought.

We all carry around mini computers in our pockets these days called phones that take the heavy burden of performing calculations, leaving us to use our grey matter on more important affairs. A patent bet calculator is just the same – it’s a cool tool you use to work out your winnings and returns from a winning bet (our tool acts as a winnings and bet return calculator). Just plug in your values, and away you go!

How to calculate my bet

Using our handy free bet calculator is super simple when want to work our your bet. Just plug in your values and away you go!

Stake – enter the amount you staked on your wager.

Odds format – select how your odds were displayed. There are three options – fractional (i.e. 5/2, etc), decimal (i.e. 3.50, etc) or American (i.e +250, etc).

Each Way – for this calculator, choose whether your bet was a ‘win only’ bet or each way.

Odds – this section will change depending on the format for the odds you’ve selected. For fractional there will be two boxes – the first for numerator (the number on top, or first i.e. 5/2) and the second for the denominator (the number on the bottom, or second i.e. 5/2). For decimal odds it’s just the number (remember the decimal point!) and for American it’s the same (remember the sign, + or – (positive odds or negative odds)).

Rule 4Rule 4 usually only applies to horse racing, or vary rarely greyhounds. It’s where a horse (or dog) is withdrawn from the race, usually close to the race start. A non-runner means that the odds have to be adjusted, and this is done as a reduction as ‘pence per pound’. If you bet on a race in which ‘Rule 4 applies’, enter the specified ‘pence per pound’ reduction from the drop down selection. Note for horses we have our own free horse bet calculator.

Result – Here you select how your chosen competitor fared. The options are ‘won’ (obvious!), ‘placed’ (finished in the set number of ‘placed’ finishes depending on the numbers in the race, which is usually four for horse races and two for greyhounds, and does not apply to most other sports), ‘dead heat‘ (a tie), ‘void’ (the bookie voided your bet) or ‘lost’ (obvious!).

Once you have chosen all the correct options, hit the calculate button. Your return (the money you get back from the bookie) and profit (return minus your stake) will be displayed.

How are betting odds calculated

Betting odds are worked out by experienced betting risk assessors who accurately know how to calculate betting odds, although much of the work is now done by algorithms. Huge databases of sporting results are consulted and the competitors assessed based on a number of factors in order to come up with the probability of them being winners.

These probabilities are then converted into odds. If a competitor is assessed as having a 20 percent chance of winning, then that is a 1-in-5 chance. This becomes 5.0 in decimal odds (one chance of happening in five attempts = 5 / 1) or 4/1 in fractional odds. Once the probability rises above 50 percent, the outcome is deemed more likely to happen than not, so the odds become odds-on, or less than evens (less that 2.0 in decimal odds).

Bet calculator odds types

You have three options for your bet odds type – fractional, decimal and American. Below is a paragraph explaining each type.

Fractional

The traditional way of representing odds in the UK. The smaller the fraction, the more fancied the competitor. Any fractional odds where the numerator (first number) is smaller than the denominator (second number) means that the competitor is ‘odds on’ and highly fancied to win.

To calculate winnings from fractional odds, you just have to do the math (or use our betting calculator!). A winning £10 bet at odds of 5/2 will win you (5 multiplied by £10, then divided by 2) £25.

Your stake is not included in a fractional odds returns calculation, so to calculate your full returns you need to add on your stake. From the bet above, you will get back £35 (£25 + £10 stake) in total.

Decimal

Decimal odds are a popular alternative to fractional odds in the UK, mainly, we believe, because nobody likes fractions and decimal odds are easier to calculate.

In our example above, fractional odds of 5/2 would be expressed as 3.50. To translate from fractional to decimal you simply express the fraction as a decimal, and then add one. The adding of one is required as decimal odds calculate your return, as opposed to your winnings.

So, a £10 bet at 3.50 would return you £35. To calculate your profit (if you don’t want to use our free bet calculator), simply subtract your stake. We do recommend using our free bet calculator UK though, as its calculations will be flawless!

American

We all know Americans like to do things differently, and that includes odds representations. The way that betting odds in America are usually expressed as a three digit number, with a + or – sign. The rules are thus:

If the number is positive, then that is the amount you’d win from a £100 bet.

If the number is negative, then that is the amount of money you’d need to put on to win £100.

So, if you bet £10 at odds of +110, you’d win £11. If you get £10 at odds of -110, you’d win £9.09. American odds do not calculate your return (only your winnings), so add on your stake for your total return.

American odds are difficult to compare to fractional and decimal odds, which is why we recommend the use of our free bet calculator.

Most popular bet calculators

As you have seen, there is a lot more to betting then just placing win bets! So that you do not have to calculate your potential winnings from a bet that has over a dozen potential smaller bets, we’ve provided a free betting calculator tool for the most popular betting options:

The Latest UK Free Bet Offers for 18 May 2024

FAQs

How does a free bet calculator work?

A free bet calculator works in the same way the calculator on your phone works. You plug in your values (see the relevant section above) and press the 'calculate' button. If you've filled everything in correctly, then your return and profit is displayed for you.

Can I use an each way bet calculator?

Sure! The tool on this very page is an each way bet calculator! Just select the 'Each Way' option when you enter your values to show that you want to use the each way bet calculator, as opposed to the single bet calculator.

Is this free bet calculator a horse bet calculator?

This bet odds calculator has mainly been designed as a horse bet calculator, but it is fine to use for other sports. Options such as 'each way' and 'rule 4' make this a very useful horse bet calculator.

Is this a double bet calculator?

It can be used as a double bet calculator, but it is easier to use as a single bet calculator. You can use our double bet calculator by clicking the link we've provided above.

What patent bet calculator odds types can I use to calculate my bet payout?

Use can use decimal, fractional or American. When you want to calculate a bet, just select the bet calculator odds representation which is the most appropriate. This is how to calculate bet worth overall - make sure you calculate bet payout correctly by setting the correct bet calculator odds format, the correct bet calculator odds and your stake.
