Football betting can be fun and exciting. Many people enjoy placing bets on games. But how do you know if you will win? One way to find out is by calculating the expected value. This article will help you understand expected value and how to calculate it.
What is Expected Value?
Expected value (EV) is a way to measure risk. It tells you what you can expect to win or lose over time. To put it simply, it is a number that shows the average outcome of your bet.
Why Is Expected Value Important?
Knowing the expected value helps you make smart bets. If the EV is positive, it means you might make money. If the EV is negative, it means you might lose money. So, it is important to calculate EV before betting.
How to Calculate Expected Value
The formula for expected value is simple:
EV = (Probability of Winning x Amount Won) – (Probability of Losing x Amount Lost)
Step-by-step Guide
- Find the Probability of Winning: This is how likely you are to win the bet. If you think a team has a 60% chance to win, then the probability is 0.6.
- Determine the Amount Won: This is how much money you will win if you win the bet. If you bet $10 and the odds are 2 to 1, you will win $20.
- Find the Probability of Losing: This is the chance of losing the bet. If the team has a 40% chance to lose, the probability is 0.4.
- Determine the Amount Lost: This is how much money you lose if you lose the bet. If you bet $10, you lose $10 if the bet fails.
Example Of Expected Value Calculation
Let’s say you want to bet on a football game. You think Team A has a 70% chance of winning.
You decide to bet $10. If Team A wins, you will win $20. If Team A loses, you lose your $10 bet.
Step 1: Find the Probability of Winning
Team A has a 70% chance to win. This means:
Step 2: Determine the Amount Won
If you win, you get $20. So:
Step 3: Find the Probability of Losing
Team A has a 30% chance to lose. So:
Step 4: Determine the Amount Lost
If you lose, you lose your $10. So:
Put It All Together
Now we can use the formula:
EV = (0.7 x 20) – (0.3 x 10)
Calculate the Winning Part
0.7 x 20 = 14. This means you expect to win $14.
Calculate the Losing Part
0.3 x 10 = 3. This means you expect to lose $3.
Final Calculation
Now we subtract the losing part from the winning part:
What Does This Mean?
Your expected value is $11. This means you can expect to make $11 on average with this bet. A positive EV means this is a good bet.
Understanding Odds
Odds are important in betting. They show how likely an event is to happen. They also tell you how much money you can win. Odds can be in different formats. The most common types are:
- Decimal Odds: Easy to understand. Just multiply your stake by the odds.
- Fractional Odds: Show how much you will win against your stake.
- Moneyline Odds: Show how much you need to bet to win $100 or how much you will win from a $100 bet.
Factors Affecting Expected Value
Several factors can affect the expected value. They include:
- Team Performance: How well a team plays affects their chances of winning.
- Injuries: Injuries to key players can change the game outcome.
- Weather Conditions: Rain or snow can affect how teams perform.
Keeping Track Of Your Bets
It is important to keep records of your bets. Write down each bet you make. Include:
- Date of the game
- Teams playing
- Amount you bet
- Odds
- Outcome of the bet
This helps you see your betting patterns. You can learn what works and what does not.
Common Mistakes to Avoid
There are some mistakes people make when betting. Avoid these to improve your success:
- Chasing Losses: Do not bet more to recover losses.
- Ignoring Research: Always research teams and players.
- Betting with Emotions: Stay calm and think logically.
