Decimal odds works in betting explained

Betting and odds attach with each other like Friday night and a pint down the local. You can’t have one without the opposite. And a bit like there are various things to back, there are different types of odds, too. You can read on for our answer to the question “How do Decimal odds work in betting?”

How do decimal odds work?

Decimal odds works in betting explained

Decimal odds also referred to as European odds, are popular due to their simplicity. They’re shown as two figures separated by a period. For example 1.25, 2.30 or 6.4. Punters use this odds to figure out which price is the best value for his or her bet by multiplying their chosen stake by the decimal price (£10 x 2.30 = £23). Calculated returns include your bet stake.

Decimal odds explained

Decimal odds tell us two things:

Price – allowing you to calculate exactly what proportion money you’ll win if your bet wins.

Probability – the chance of your chosen bet might actually win.

These odds don’t show the potential returns without stake like fractional odds. It represents the return from bet including stake.

Decimal ‘odds against’ prices:

6. 0–£1 stakex6=£6 returns

6. 0–£5 stakex6=£30 returns

Bets placed at ‘evens’:

2. 0–£1 stakex2=£2 returns

2. 0–£5 stakex2=£10 returns

or 2. 0–£10stakex2=£20 returns

Decimal ‘odds on’ prices:

1. 5–£1stakex1. 5=£1. 50 returns

1. 5–£5 stakex1. 5=£7. 50 returns

or 1. 5–£10 stakex1.5=£15 winnings

The replacement format of Decimal odds is Fractional odds. There’s no mathematical difference between the 2 types of odds. Instead, it’s only a different way of displaying equivalent information. Some people like to prefer decimals odds while others prefer fractions odds.

What do odds mean?

Odds are simply a mirrored image of the implied chance, or likelihood, of the result of an occasion.

Let’s take a look at tennis, where Andy Murray is playing an early-round match against a comparatively unknown player. The bookmakers assume that Andy has 80% of winning chance, therefore his opponent’s winning chance will be 20%.

We’ll assume that we’re handling a non-profit making bookmaker. To cost up their book they have to separate it 80% / 20% = 100%

In decimal odds format, this is often very easy: they simply take 100 (the total chance of all outcomes happening in an occasion will always be 100%), and divide it by Andy’s 80% chance:

100% ÷ 80% = 1.25

The odds of his opponent are:

100%÷20%= 5.00

When you bet £100 on Andy to win, and if he does, you’ll get £125 back from the bookmaker. Your initial stake will be included, so you’ll have won £25:

£100 x 1.25 = £125


By using the decimal odds you’ll calculate the probability of the result of an occasion happening. For example:

6. 0 is calculated as 100/6. 0=0. 16 or 16% probability

2. 0 is calculated as 100/2. 0=0. 50 or 50% probability

1. 5 is calculated as 100/1. 5=0. 66 or 66% probability

Converting decimal odds to implied probability

It’s also easier to figure out the reverse of these odds, i.e. convert them into the implied chance of the result happening as you merely divide 100 by the odds:

100% ÷ 1.25 = 80%

Converting fractional odds to decimal

Although it’s easy to vary all of your online bookmakers to display the changes as decimals, there could also be times when that’s not an option. It’s useful to understand the way to convert fractional odds to their decimal equivalent. Fortunately, it’s very easy too: just divide the first number by the second and add 1.

So taking odds of Andy above their fractional equivalent would be 1/4

1÷4=0. 25+1=1. 25

Converting decimal odds to fractional

It’s really direct. Just minor to 1.00 from the decimal price, convert the worth to a fraction then simplify that fraction are far as possible. For example:

6. 0 as fractional odds would be 5/1

(6. 0 – 1 =5) =5/1

8. 5 as fractional odds would be 15/2

(8. 5 – 1 =7. 5) =15/2

1.5 as odds would be 1/2

How to use Decimal odds

Matched betting might be a clever method to turn bookmakers’ free bets and promotions into real money. Although it involves odds and betting, it’s still not gambling. The method of matched betting means you eliminate the risks usually related to gambling. And you don’t need to roll in the hay on you’re own. You don’t even get to know anything about sport!

Why use decimal odds?

It’s much easier to match the closeness within the odds for matching those bets.

The higher the odds, the less the prospect of the event occurring.

The lower the odds, the upper the prospect of the event occurring.

So, to conclude, decimal odds are a simple way to compare the chances at both the bookmaker and therefore the exchange to seek out the simplest matched bets.
