What Is The Expected Goal (xG)?

Expected Goals (xG) is a metric that calculates the probability of chances turning into a goal in a football match. There are models that base the value on several factors like shot location, angle, received pass type, goal distance, and some others. 

For example, a shot from a tight and long angle will have a lower xG value. Whereas, an open play opportunity will have higher xG and more chance of scoring, compared to a long-range effort.


The bookmakers will fix a value of 0.76x for set pieces like penalty shootouts. Because the chances for getting a goal is more likely here. 

Finally, as an example, a team with an xG of 1.0 means that they might score 1 goal on average throughout the whole match. 

xG is useful for understanding a team’s attack strength and performance. This can be helpful for the bettors to take more data-driven betting decisions.

How Is xG Calculated? 

There are several mathematical models that you can use to calculate Expected Goals, xG. Each model has different characteristics. However, all of them follow some common factors which have already been mentioned above.  This was used most during the FIFA World Cup back in 2022. 

These models calculate the probable value of each shot ending up at the back of the net. The sum of all these probable values of goals is combined together to calculate the total xG of the team. 


These calculations are done by several techniques, where the historical data are used to determine the average number of goals that have been scored from similar factors in the past. 

The exact value of xG can vary depending on the data, and the model. But, it is very effective in measuring a team’s chance of scoring and winning in the match. 

Impact Of xG On Sports Betting

Risks Related to Unpredicted Actions

The in-game stats don’t dictate the entirety of a football game. There are several other factors that can hugely affect the result of a football match. Factors like offsides, fouls, injuries, tactical changes, or referee decisions can change the outcome of the game. 

However, xG models don’t use these factors during calculations by the xG models. So these factors in a match can make the xG calculation wrong. 

Low Data Quality

Bookmakers that calculate xG base the calculations on the historical data of the goals scored in similar circumstances. The accuracy of this calculation hugely depends on the quality and amount of data that the model in question is using.

if the models use low-quality data, predicted xG values might not be accurate, resulting in taking wrong betting decisions. 

Different Models Can Predict Different Values

Experts use several models to determine the xG values. Each model can provide different xG values for the same shot. So it is important to choose the appropriate xG calculation method for better decision-making.
