1. What is Goal Difference in Football?

Definition: Goal difference (GD) is a metric used to rank teams when they have the same number of points in league competitions.

Purpose: It serves as a tiebreaker between teams with equal points, measuring the difference between goals scored and goals conceded.

2. How is Goal Difference Calculated?

The calculator uses the formula:

Where:

• \( GD \) — Goal difference (dimensionless)
• \( G_f \) — Goals for (goals scored by the team)
• \( G_a \) — Goals against (goals conceded by the team)

Explanation: A positive GD means the team scored more than they conceded, while negative means they conceded more than scored.

3. Importance of Goal Difference

Details: In many leagues, GD is the primary tiebreaker after points. It reflects a team's overall performance better than just wins/losses.

4. Using the Calculator

Tips: Enter the total goals scored by the team and total goals conceded. Both values must be ≥ 0.
