Fractional Odds - UK's favorite choice

By Lenn Robbins

Calculating Fractional Odds: Fells like 4th grade all over again

While there are different formats for presenting odds, fractional odds have stood the test of time and remain a popular choice, particularly in the United Kingdom.

In this quick guide to fractional odds and how to calculate them, we'll provide real examples of fractional odds in action, explain how to convert American and decimal odds to fractional odds, introduce the fractional odds calculator, and emphasize the importance of comparing odds before placing your bets.

Get ready to take your betting expertise to the next level!

Yes, it involves... Fractions! :)

Fractional odds, also known as British odds, are presented as a fraction, with the numerator representing the potential profit and the denominator indicating the amount wagered.

 

Converting American and Decimal Odds to Fractional Odds

Knowing how to Convert American and decimal odds to fractional odds allows you to better understand different sportsbook offers, at least when these are presented in a format you are less familiar with.

Let's explore the conversion process using real examples:

Example 1: NFL Moneyline Bet

American Odds:
Team A: +150
Team B: -200

Decimal Odds:
Team A: 2.50
Team B: 1.50

To convert American odds to fractional odds, we use the following formulas:

Positive American Odds: Fraction = (Odds / 100) + 1
Negative American Odds: Fraction = (100 / Odds) + 1

Using the formulas, we get:

Team A: +150 ➞ Fractional Odds: 3/2
Team B: -200 ➞ Fractional Odds: 1/2

To convert decimal odds to fractional odds, we assess the implied probability and express it as a fraction:

Team A: 2.50 ➞ Fractional Odds: 6/4
Team B: 1.50 ➞ Fractional Odds: 1/2

Fractional Odds Calculator: How can it help me?

The fractional odds calculator is a valuable tool that simplifies the process of calculating potential winnings and assessing implied probabilities based on fractional odds. By entering the odds, the calculator swiftly provides you with the potential profit and the implied probability for the given outcome. You can also play around with bet amounts and better understand how your net win will look like if you decide to make the bet you were thinking of.

Odds Comparison: Elevating Your Betting Game

Comparing odds from various sportsbooks is a critical practice for every bettor.

It allows you to identify the best value bets and maximize your potential returns.

Let's illustrate the importance of odds comparison with an example:

Example: Baseball Match

Sportsbook A:
Team X: 4/1
Team Y: 1/2

Sportsbook B:
Team X: 9/2
Team Y: 4/9

In this scenario, if you want to bet on Team X to win, Sportsbook B offers better fractional odds of 9/2 compared to Sportsbook A's odds of 4/1. By choosing Sportsbook B, your potential profit would be higher for the same outcome.

Over time, consistently selecting the sportsbook with better odds can significantly impact your overall betting profitability.

SPORTS ODDS CALCULATOR FAQS

Fractional odds are a popular odds format used in sports betting, particularly in the United Kingdom (horse racing for example usually features fractional odds).

They represent the potential profit (numerator) relative to the amount wagered (denominator).

Example: Let's consider a horse race where a horse has fractional odds of 3/1.

If you wager $10, a winning bet would yield a profit of $30 (3 times the stake).

To convert positive American odds to fractional odds, use the formula: Fraction = (Odds / 100) + 1.

For negative American odds, the formula is: Fraction = (100 / Odds) + 1.

Example: If the American odds are +250, the fractional odds would be 3/2. For -200 odds, the fractional odds would be 1/2.

To convert decimal odds to fractional odds, assess the implied probability and express it as a fraction.

Example: If the decimal odds are 2.50, the fractional odds would be 6/4.

If the decimal odds are 1.50, the fractional odds would be 1/2.

 

The fractional odds calculator simplifies the calculation of potential winnings and implied probabilities.

Enter the fractional odds, and the calculator will provide the potential profit and implied probability for the given outcome.


Example: If you enter the fractional odds 7/4, the calculator would display a potential profit of $7 for every $4 wagered and an implied probability of 36.36%.

Comparing odds from different sportsbooks allows you to find the best value bets and maximize your potential returns.

Small differences in odds can significantly impact your overall profitability.

Example: If you want to bet on a football match and Sportsbook A offers fractional odds of 2/1, while Sportsbook B offers 9/5 for the same outcome, choosing Sportsbook B would result in higher potential profits.

By consistently selecting the sportsbook with the best odds for a specific outcome, you increase your potential profits over time.

Even a slight improvement in odds can have a significant cumulative effect on your overall returns.
Example: Suppose you place 100 bets with an average odds improvement of 0.05 in your favor.

Over the long run, this could result in an additional 5% profit.

At Bet Basics you will find the top US sportsbooks with updated odds for all sports events, including props, futures, moneyline, spread and totals.

Fractional odds can be used for a wide range of bets, including moneyline, point spread, and over/under bets across various sports.

Example: If you're betting on a basketball game, fractional odds can be used to understand the potential profit and implied probability for the moneyline, point spread, and total points (over/under) bets.

Fractional odds are one of several formats used in sports betting, including decimal odds and American odds.

Each format presents the same information differently.

Fractional odds are popular in the United Kingdom, while decimal odds are commonly used in Europe and the rest of the world, except USA.


Example: If a horse has fractional odds of 5/1, the equivalent decimal odds would be 6.00, and the American odds would be +500.

Understanding fractional odds allows you to evaluate the potential profitability and implied probabilities of different betting options. By comparing odds, you can make more informed decisions and select bets that offer the best value.

Example: If you analyze the fractional odds for multiple bookmakers and identify higher odds for a specific outcome, you can place your bet with the bookmaker offering the better odds to increase your potential profits.

Fractional odds are widely recognized and used in the sports betting industry, especially in the United Kingdom.

However, it's essential to familiarize yourself with different odds formats, as you may encounter decimal or American odds when betting with international sportsbooks.

Example: If you're betting on an international tennis match, you may come across decimal odds on a European sportsbook and fractional odds on a British sportsbook.

Lenn Robbins

Sports Journalist

Hi, I'm Lenn Robbins, a long-time sportswriter who still holds the detention record at Bildersee Junior High School in Brooklyn, N.Y., where I was born and raised. I came out of the womb a Mets fan, was baptized a Knicks fans and through the power of TV, became a Cowboys fan, which explains why I'm in group therapy. The name of my fantasy football league team is Sexual Chocolate. Anyone who can explain the origin of said team name, please hit me on Twitter @LennRobbins I live in NYC with, Nicole, who I have nominated for sainthood for putting up with Lenny the Loser, and three really cool young guns - Harry, Gwen and Colin as well as a ridiculous neurotic but sweet rescue mutt, Linsey, who is afraid of flies in the house. True. My journalism career started at Greenwich Time in Greenwich, Connecticut where I was awarded a varsity field hockey letter (one of my most prized possessions) before moving to The Record (N.J.) and then the NY Post where I covered everything except curling, despite covering the 2004 Winter Olympics in Salt Lake City, where I shorted out the ski lift because I didn’t know when to jump off. I’m a two-time APSE winner and the recipient of the Metropolitan College Football Writers Association's Good Guy Award (also a prized possession). Despite looking more like Herman Munster than Idris Elba, I was a college basketball and football insider for ESPN, where I got to interview LSU QB Matt Mauck on Canal Street, the morning after the Tigers won the national championship. After working for the Brooklyn Nets for two seasons, where learned not to cry when Kevin Garnett gave him the hairy eyeball, I now teach sports journalism at several NYC-area universities and am on a constant search for the perfect parlay at BetBasics.com.
