If you’re new to sports betting, one of the first things you’ll need to understand is how to read betting odds. Odds not only indicate how much you can win on a wager—they also reveal the bookmaker’s prediction of the outcome. Whether you prefer decimal, fractional, or American odds, knowing how they work is essential to making informed bets.
Online platforms like vaobong88 make it easy to switch between odds formats and offer clear explanations to help beginners get started confidently.
What Are Betting Odds?
Betting odds represent the probability of an outcome and determine the amount you can win. They are set by bookmakers based on statistics, public opinion, and real-time factors like injuries or weather conditions.
There are three common formats used around the world:
- Decimal Odds (used in Europe, Canada, Asia)
- Fractional Odds (popular in the UK and Ireland)
- American Odds (also known as Moneyline, used in the US)
Let’s break down each format.
1. Decimal Odds
This format is the easiest to understand and is used on most international platforms.
Example:
- Odds: 2.50
- If you bet $10, your return would be $10 × 2.50 = $25
- Profit = $25 – $10 = $15
The decimal number represents your total return, including your original stake.
2. Fractional Odds
Used mainly in the UK, fractional odds are written like 5/1 (read as “five to one”).
Example:
- Odds: 5/1
- You win $5 for every $1 wagered.
- Bet $10, win $50 + your original $10 = $60 total return
Smaller fractions like 1/2 mean you win less than your stake, indicating a higher probability outcome.
3. American Odds (Moneyline)
These odds can be positive or negative:
- Positive (+200): Bet $100 to win $200
- Negative (-150): Bet $150 to win $100
Example:
- +250: A $100 bet pays $250 profit ($350 total return)
- -120: You need to bet $120 to win $100 profit
This system is more complex but useful once you get the hang of it.
Implied Probability
Every odds format can be converted into an implied probability, which shows the likelihood of the outcome.
Formula for Decimal Odds:
Implied Probability = 1 / Decimal Odds × 100
Example:
- Odds: 2.00
- 1 / 2.00 = 0.5
- Implied Probability = 50%
Understanding this helps you spot value in the odds and decide whether a bet is worth it.
Choosing the Right Format
Most sportsbooks let you toggle between formats in the settings. Choose the one you’re most comfortable with. Many international bettors prefer decimal odds for their simplicity, while UK bettors stick to fractions.
