What is the typical elimination rate in the first round of a single elimination tournament?

In a single elimination tournament, the typical structure involves pairing teams or players against each other, where the winner advances to the next round while the loser is eliminated from the competition. In the first round, half of the teams participating will lose their matches, resulting in 50% of the players being eliminated. This occurs because each match results in one competitor moving forward and one being knocked out.

For example, if there are 16 teams in the tournament, there will be 8 matches in the first round. Consequently, 8 teams will win and proceed to the next round, while the remaining 8 teams will be eliminated. This consistent pattern across all single elimination tournaments makes the elimination rate in the first round typically 50%.
