In the United Kingdom and Europe, the two most prevalenttype of betting odds are fractional and decimal, both of which produce the sameresult.

When it comes to decimal odds, your stake is always factored into the return that you calculate but this is not the case when following the fraction method. In terms of the latter, if you put £1 on odds of 4/1 you will receive £4 in profit but also get your £1 stake back too – so £5 in total.
Most traditional bookmakers have historically usedfractional odds, while decimal odds tend to be found on betting exchanges.
Read on as we show you howbetting odds work and help you get to grips with the differences betweenfractional and decimal prices.
Fractional Odds
Fractional odds have their roots in horse racing in the UKand Ireland, with most bookmakers using them to display prices for each race.
These types of odds have also been used across the sportingspectrum and show how much profit a bettor will make against their stake iftheir selection is successful.
In simple terms, the number on the right of the fraction isthe amount you must stake to win the figure on the left.
For instance, a £1 stake on a horse to win a race at odds of2/1 would return a £2 profit if it finishes first. The punter would thereforereceive £3 (£1 stake + £2 profit).
Decimal Odds
The launch of betting exchanges sparked a change in the wayodds are displayed, with decimals used to show the prices on offer for eachevent.
Decimal odds are generally displayed to two decimal places,so if you place a £10 bet at odds of 3.50 your return would be £35 (£10 stake x3.50 = £35).
Although it may take a while for punters more familiar withfractional odds to understand decimal odds, they are a little easier tounderstand.
As opposed to displaying the profit you make on your stake,they convey the exact return you would receive if a selection is successful.
Converting Fractional to Decimal Odds
To convert fractional odds to decimal, you must divide thefirst figure by the second figure and then add 1.00.
For instance, fractional odds of 11/4 is 11 divided by fourwhich equals 2.75. If you add 1.00, you are left with decimal odds of 3.75.
Using the same odds, if you place a £4 bet at fractionalodds of 11/4 and your selection is successful your return would be £15 (£4stake + £11 profit = £15).
Placing a £4 bet at decimal odds of 3.75 also returns £15(£4 stake x 3.75 = £15) if your selection wins its particular event.

Converting Decimal Odds to Fractional
It is worth noting that not all decimal odds translate tofractional odds that are recognisable as the ones used traditionally in bettingmarkets.
For instance, if you have decimal odds of 1.80 this equatesto fractional odds of 4/5, but if the price shortens to 1.74, this equates to astrange-looking 37/50.
This anomaly is due to the traditional nature of thefractions used by bookmakers, which weren’t to the same full scale found indecimal odds.
This method allowed bookies to build an additional profitmargin into their books and shave extra value off the prices they offered topunters.
Using Odds Conversion Tools
There are numerous online sites which offer punters thechance to convert odds easily using innovative betting tools.
These often have four fields – fractional odds, decimalodds, American odds and implied probability (percentage).
To use an odds converter, enter a value into any field and itwill automatically convert the odds into all of the other formats.
Using an odds convertor is a great way to take the hassleout of calculating odds, particularly if the betting site you visit displaysthem in a way you are unfamiliar with.

By convention only a set of fractions are used in fractional odds betting markets. The set does not include exact mathematical equivalents to all possible decimal and American odds. We use the closet fraction that is used in betting markets.
For example, the exact mathematical equivalent of decimal odds 30 is fractional odds 29/1. However 29/1 is not used in betting markets, instead 30/1 is used, so that is what appears in this converter.
