How long is the stoppage time typically added to a soccer match?

Stoppage time, also known as injury time or added time, is determined by the referee at the end of each half of a soccer match to compensate for various interruptions that occurred during regular play, such as player injuries, substitutions, or other delays. The referee assesses the amount of time lost and makes a judgment call on how much extra time should be added, making it variable for different matches and situations. This is why the correct answer is that it varies depending on the referee's decision. Each match can see different amounts of stoppage time as the circumstances during the game dictate the need for additional minutes.
