Enter the number of goals scored by the home team in the first match, the number of goals scored by the away team in the second match, the number of goals scored by the away team in the first match, and the number of goals scored by the home team in the second match into the calculator to determine the winner using the away-goals rule. (In a standard two-legged tie, the teams swap home/away between the first and second match.)

Away Goal Rule Formula
The away-goals rule is determined by comparing aggregate goals over two legs first, and (only if aggregate is tied) comparing away goals. The formulas below compute (1) the aggregate goal difference and (2) the away-goal difference used as the tiebreaker when aggregate is tied.
\begin{aligned}
W &= (H1 + A2) - (A1 + H2) \\
D &= A2 - A1
\end{aligned}Variables:
- W is the aggregate goal difference: (aggregate for the team that was home in the first match) minus (aggregate for the team that was away in the first match).
- D is the away-goal difference used only when the aggregate is tied (W = 0): (away goals scored by the first-match home team) minus (away goals scored by the first-match away team).
- H1 is the number of goals scored by the home team in the first match
- A2 is the number of goals scored by the away team in the second match
- A1 is the number of goals scored by the away team in the first match
- H2 is the number of goals scored by the home team in the second match
To determine the winner, first compare aggregate goals across both matches: (H1 + A2) versus (A1 + H2). If W > 0, the first-match home team wins on aggregate; if W < 0, the first-match away team wins on aggregate. If W = 0 (aggregate tied), apply the away-goals tiebreaker by comparing A2 (away goals in the second match) to A1 (away goals in the first match): if D > 0 the first-match home team wins on away goals, if D < 0 the first-match away team wins on away goals. If both aggregate and away goals are tied (W = 0 and D = 0), the tie is not decided by the away-goals rule and is typically decided by extra time and/or penalties depending on competition rules.
What is an Away Goal Rule?
The Away Goal Rule is a method that has been used in football (soccer) to determine the winner in two-legged knockout matches, where each team plays one match at home and one away. If the aggregate score is tied after both games, the team that scored more goals in their away match is declared the winner. This rule was intended to encourage attacking play from the visiting team and to provide a tie-breaker that takes into account the perceived difficulty of scoring goals away from home. (Note: many competitions have modified or abolished the away-goals rule, so always check the specific competition’s regulations.)
