Understanding betting odds is a key skill for anyone starting online betting. Odds show both the likelihood of an outcome and the potential payout. Learning how to read them helps you make smarter bets and manage risk effectively.
Different Formats of Betting Odds
There are three main formats of betting odds: decimal, fractional, and American. Each displays the same information in a different way.
-
Decimal Odds: Common in Europe, Canada, and Australia. The number shows your total payout for each unit staked, including your original stake.
-
Fractional Odds: Popular in the UK and Ireland. Written as fractions, they show how much profit you will make relative to your stake.
-
American Odds: Common in the US. Positive numbers indicate the profit on a $100 bet, while negative numbers show how much you need to stake to win $100.
How to Calculate Payouts
Knowing how to calculate payouts is essential.
-
Decimal example: Odds of 2.50 with a $10 bet → $10 × 2.50 = $25 total payout ($15 profit).
-
Fractional example: Odds of 3/1 with a $10 bet → $10 × 3 = $30 profit ($40 total payout including stake).
-
American example: Odds of +150 with a $100 bet → $150 profit; Odds of -200 → stake $200 to win $100 profit.
Understanding Implied Probability
Odds also indicate the implied probability of an event occurring. This is a way to measure how likely a result is according to the bookmaker.
-
Decimal odds → 1 ÷ decimal odds × 100 = implied probability (%)
-
Fractional odds → denominator ÷ (denominator + numerator) × 100 = implied probability (%)
Understanding probability helps you decide whether a bet offers good value.
