Fractional Odds Betting Explained
A familiar sight to many punters in New Zealand, fractional odds are one of the most popular ways of showing the chance of a win in online sports betting. It one of the oldest forms taken, and it is one of the easiest to understand too.
Whether you love betting on your favourite football team or on the horse tipped to win the Auckland Cup, you can work out how much you stand to win quickly and easily using this wagering format. The Kiwi sportsbooks we recommend for the best football odds online give you the option of choosing the format in which they are shown, so you can opt to convert them from fractional to decimal if preferred and develop your own sports betting strategy.

Placing Profitable Wagers
Before we look at how to calculate fractional odds online, we need to stress the importance of understanding them. The best bets you could place are informed bets.
Many punters think they should find out as much as they can about the participants in the event, as well as field conditions, weather conditions, and injury reports. Such information is essential to ensuring you are not placing bets that are a waste of your time and money. However, this is not all there is to informed online sports betting.
You should also be aware of the profits a bet potentially could yield. The easiest way to see how much your bet could win is to calculate it using the fractional amount given at the best New Zealand online and mobile sports betting sites.
Calculating Fractional Odds
With this format what you see is the net amount you could win, relative to the bet you place, in fractional form. Let’s say, for example, that the best football odds you find for your favourite team are 4/1.
The number on the left, that is the 4, is called the numerator, and it lets you know how much your bet could yield. The number on the right, that is the 1, is the denominator, and it indicates what the size of your bet would be to win the amount indicated by the numerator.
In our example of 4/1, a winning bet of NZ$100 would yield NZ$400 profit. Remember, if your bet wins, you also get your bet back, which means the total amount you would receive once the winner has been declared is NZ$500.
It is important to pay attention to the odds available at the bookmakers we promote for punters in New Zealand. Do not get confused between 4/1 and 1/4, because they are definitely not the same! In the case of the best football odds being 1/4, a bet of NZ$100 would yield a profit of only NZ$25, so the total you would receive at the end of the match is NZ$125.
Now you know more about how this betting format works, you can wager with confidence at the best sports betting brands in New Zealand!
