What is goal difference and how does it work in football?
Goal difference is the difference between the goals a team scores and the goals it concedes in a competition. It is commonly used to separate teams level on points in the table.
Definition of goal difference
Goal difference is calculated with a simple equation: goals scored minus goals conceded. If a club scores 18 goals and concedes 12, its goal difference is +6. If it scores 10 and concedes 14, the goal difference is -4. A positive goal difference means the team has scored more than it has conceded; a negative goal difference means the opposite.
How to calculate goal difference
The formula is: goal difference = goals scored − goals conceded. “Goals scored” are the goals scored by the team, while “goals conceded” are the goals it has allowed. A 3–0 win increases the goal difference by three. A 1–0 defeat reduces it by one.
Why goal difference appears in the table
In league competitions, such as the Campeonato Brasileiro, teams earn points each matchday: normally three for a win, one for a draw and none for a defeat. When two or more teams finish level on points, the regulations may use goal difference as a tiebreaker. The higher the goal difference, the higher the position.
Practical example
Imagine two clubs with 20 points. Team A has scored 17 goals and conceded 11, giving it a goal difference of +6. Team B has scored 19 and conceded 15, giving it a goal difference of +4. Despite having the same number of points, Team A finishes ahead if goal difference is the first applicable tiebreaker in the regulations.
Goal difference is not the same as goals scored
Goals scored and goal difference are different statistics. A team can score many goals and still have a low goal difference if it also concedes frequently. For example, a team with 30 goals scored and 28 conceded has a goal difference of +2. Another with 22 scored and 15 conceded has a goal difference of +7 and generally has the advantage in a goal-difference tiebreaker.
The regulations determine the order of tiebreakers
Each competition publishes its own criteria. In the Brasileirão, goal difference usually comes after the number of wins among teams level on points, and before goals scored. In knockout tournaments, aggregate goal difference can decide who progresses, but the rule varies: some competitions take the tie to extra time and penalties rather than using goal difference as the final tiebreaker.
