Odds (also called prices or lines) represent the probability of a particular outcome, as determined by the bookmaker. The higher the probability, the lower the odds, and vice versa.
🔍 Example from a bookmaker:
The odds for Team 1 to win are listed as 2.795, typically rounded to 2.7. Players place their bets based on these odds. To calculate the potential payout, simply multiply the stake by the odds.
▎How Are Betting Odds Calculated?
1. Estimating Probability: Bookmakers begin by assessing the probability of each outcome. For example, in a match between Liverpool and Southampton:
2. Odds Calculation Formula:
Using the above probabilities:

▎Reverse Example: Converting Odds into Probability
In a match between Fiorentina and Verona:
Note that the total exceeds 100% (102.74%) due to the bookmaker’s margin — their built-in profit percentage.
🪙 Example Payout Calculation:
If a player bets $ 7.70 on Fiorentina to win at odds of 2.1:
7.70×2.1 = $ 16.17

▎How Are Betting Odds Calculated?
1. Estimating Probability: Bookmakers begin by assessing the probability of each outcome. For example, in a match between Liverpool and Southampton:
- Liverpool win: 77%
- Draw: 15%
- Southampton win: 8%
2. Odds Calculation Formula:
- Odds = 100 / Probability (%)
Using the above probabilities:
- Liverpool win → 1.29 (100 / 77)
- Draw → 6.66 (100 / 15)
- Southampton win → 12.5 (100 / 8)

In a match between Fiorentina and Verona:
- Fiorentina win: 47.61%
- Draw: 28.4%
- Verona win: 26.73%

▎Step-by-Step: How Bookmakers Set Odds
- Analytical Modeling: analysts evaluate outcome probabilities based on many factors — team motivation, player lineups, historical stats, etc.
- Adding the Margin: the raw probabilities are converted into odds and then adjusted with the bookmaker’s profit margin.
- Market Comparison: odds are benchmarked against other bookmakers to stay competitive.
