A fourth official raises the board and a stadium reacts: four minutes can feel too short to one team and endless to the other. The number is commonly called injury time, added time or stoppage time, but none of those names means the referee simply counts injuries.
Under football's Laws of the Game, the referee makes an allowance for playing time lost during each half. The calculation includes several types of interruption, and the number displayed on the touchline is a minimum, not a promise that the whistle will sound at an exact second.
What Counts Toward Stoppage Time?
Law 7 published by The IFAB gives referees a list of delays that may be included. They include:
- Substitutions
- Assessment or removal of injured players
- Deliberate time-wasting
- Disciplinary sanctions
- Drinks or cooling breaks allowed by competition rules
- VAR checks and on-field reviews
- Goal celebrations
- Significant delays to a restart
- Other interruptions caused by an outside agent
The key word is lost. A referee is not trying to make every half contain 45 minutes of the ball being in motion. Normal events such as throw-ins, routine free kicks and the ball going out are part of football's running clock. Added time is intended to restore time lost through more substantial delays.
Who Decides the Number?
The referee is the official timekeeper. Assistant referees and the fourth official can help communicate information, but the final allowance belongs to the referee.
During the half, the officiating team records stoppages and the referee decides how much time should be added. Near the end of the 45th or 90th minute, that figure is communicated to the fourth official, who displays it on the electronic board.
Technology may help officials track individual interruptions, but there is no universal public equation that converts every substitution or celebration into the same number of seconds. Context matters. A substitution completed promptly does not waste as much time as a slow one, and a brief VAR check is different from a long on-field review.
Why the Board Shows a Minimum
If the board displays six minutes, the half cannot normally end before those six minutes have been played. It can, however, continue beyond them.
Imagine a goal is scored two minutes into a displayed six-minute period. The celebration, VAR confirmation and restart take another two minutes. The referee can add that fresh delay, meaning the final whistle may arrive closer to the 98th minute than the 96th.
This is why television graphics often show “minimum of six minutes.” The referee is still counting time lost after the board goes up.
Can a Referee Shorten Added Time?
The displayed allowance is not supposed to be reduced because the score appears settled or the crowd wants the match to end. The referee may increase it when further delays occur.
There is one practical complication: football laws give the referee authority over timekeeping, so the whistle rarely comes at a perfectly predictable tenth of a second. An attacking move is not automatically entitled to continue simply because the ball is near the penalty area, although referees often avoid ending a half during an immediate active phase when only a moment remains.
A penalty kick is different. If time expires after a penalty has been awarded, the half is extended for the kick to be completed.
Why Added Time Has Become Longer
Major competitions have increasingly instructed referees to account more accurately for celebrations, substitutions, VAR and deliberate delays. The result is more halves with seven, eight or even ten minutes added.
The IFAB has also introduced measures aimed at reducing tempo disruption. Its 2026 decisions included visible countdowns for certain delayed restarts and a one-minute period off the field for many treated outfield players, subject to exceptions. Those measures try to discourage stoppages, while Law 7 still allows the referee to restore time that is actually lost.
Longer added time does not mean football has changed to a stop-clock sport. The clock still runs continuously. Officials are simply being encouraged to make the final allowance closer to the delays they observed.
Stoppage Time Versus Extra Time
The terms are often mixed up, but they describe different things.
Stoppage time is added to the end of each normal or extra-time period to compensate for delays. Extra time is the separate 30-minute phase, usually two 15-minute halves, used by some knockout competitions when the score is level.
Our guide to extra time and penalty shootout rules explains what happens after 90 minutes in knockout matches.
The simplest way to read the board is this: the number is the referee's minimum estimate of time lost so far. Every meaningful delay after it appears can move the final whistle later.
