How to Read Betting Odds?

When opening a sports betting app for the first time, numbers like -110 or +250 may seem confusing. However, understanding how to read betting odds is essential because it shows:

1. How much you will win if your bet is successful
2. Which team is the favorite
3. Which team is the underdog
4. What the implied probability of winning is

Let’s take an example from a Saudi Pro League match between Al Hilal and Al Nassr:

Al Hilal -150, Al Nassr +200.

This means Al Hilal is the favorite to win (indicated by the minus sign), while Al Nassr is the underdog (indicated by the plus sign).

What Does the (+) Symbol Mean in Betting Odds?

If you bet $100 on a team at +200, you will win $200 in net profit (for a total payout of $300 including your stake).

Example: If Al Nassr is +200 and wins, a $100 bet earns you a $200 profit.

What Does the (−) Symbol Mean in Betting Odds?

If Al Hilal is listed at -150, you need to bet $150 to win $100 in profit.

The larger the negative number, the more you must stake to win $100.

On some betting sites, odds appear in this format:

• Al Hilal 1.60
• Al Nassr 3.00

The calculation is simple:

Stake × Decimal Odds = Total Payout

Example:

100 × 3.00 = $300 (Net profit of $200)

Odds of 1.60 indicate that the team is a strong favorite, while 3.00 means the team is the underdog but offers a higher potential return.

What Is Implied Probability in Online Betting?

Implied probability represents a team’s estimated chance of winning according to the bookmaker’s odds.

In American odds:

• For negative odds:
  Number ÷ (Number + 100)

• For positive odds:
  100 ÷ (Number + 100)

Example:

• Al Hilal -150
  Calculation: 150 ÷ (150 + 100) = 60% approximate win probability
• Al Nassr +200
  Calculation: 100 ÷ (200 + 100) = 33.3%

The higher the percentage, the greater the implied chance of winning according to the bookmaker’s evaluation.

• Profit: The amount you win excluding your original stake
• Total Payout: Your profit plus your original stake
  
  Example:
  
  If you bet $100 at +200
  
  Profit = $200
  
  Total Payout = $300

Once you understand how to read betting odds, you will be able to:

1. Identify the favorite
2. Calculate your potential profit before placing a bet
3. Compare odds across different platforms
4. Spot value bets

Sports betting is not just about predicting who will win, but about understanding the numbers behind the odds.
