Types of Betting Odds
There are three main types of betting odds used in the UK:
- Fractional Odds: The most common format in the UK, fractional odds are represented as a fraction (e.g., 5/1 or 10/3). The numerator (top number) shows the potential profit, while the denominator (bottom number) represents the amount you need to stake to win that profit.
- Decimal Odds: Increasingly popular in Europe and online betting, decimal odds are displayed as a single number (e.g., 2.00 or 3.50). The number represents the total return for each pound staked, including the initial stake.
- Moneyline (American) Odds: Less common in the UK, moneyline odds are presented as either a positive or negative number (e.g., +200 or -150). Positive numbers indicate the potential profit from a £100 stake, while negative numbers show the amount needed to stake to win £100.
How to Calculate Potential Winnings
To calculate your potential winnings, you can use the following methods for each type of odds:
- Fractional Odds: Divide the numerator by the denominator and multiply by your stake, then add your initial stake. For example, a £10 bet at 5/1 odds would return (£10 * 5/1) + £10 = £60.
- Decimal Odds: Multiply your stake by the decimal odds to calculate your total return. For example, a £10 bet at 3.50 odds would return £10 * 3.50 = £35.
- Moneyline Odds: For positive odds, divide the odds by 100 and multiply by your stake, then add your initial stake. For negative odds, divide 100 by the odds (ignoring the minus sign) and multiply by your stake, then add your initial stake. For example, a £10 bet at +200 odds would return (£10 * 200/100) + £10 = £30, while a £10 bet at -150 odds would return (£10 * 100/150) + £10 = £16.67.
Understanding Probability and Implied Probability
Odds also represent the implied probability of an event occurring, which can be calculated as follows:
- Fractional Odds: Divide the denominator by the sum of the numerator and denominator, then multiply by 100. For example, the implied probability of 5/1 odds is (1 / (5+1)) * 100 = 16.67%.
- Decimal Odds: Divide 1 by the decimal odds, then multiply by 100. For example, the implied probability of 3.50 odds is (1 / 3.50) * 100 = 28.57%.
- Moneyline Odds: For positive odds, divide 100 by the sum of the odds and 100, then multiply by 100. For negative odds, divide the absolute value of the odds by the sum of the odds and 100, then multiply by 100. For example, the implied probability of +200 odds is (100 / (200+100)) * 100 = 33.33%, while the implied probability of -150 odds is (150 / (150+100)) * 100 = 60%.
