LBP in rugby stands for "Bonus Points Losing". It is a term used to measure the results of rugby matches between two teams, one with more players on the field at the end of play. P represents "Points" and is calculated by subtracting B from PD, which shows how many bonus points were scored by either side compared to their actual point differential.

It is important to note that LBP is not the same as the bonus point system used in rugby tournaments. The French professional league, Ligue Nationale de Rugby (LNR), uses a bonus point system in its two competitions, the Top 14 and Rugby Pro D2. The French system awards 4 points for a win, 2 points for a draw, and 1 "bonus" point for winning while scoring the equivalent of at least 3 more tries than the opponent (15 points) .

Bonus points are also awarded in rugby union tournaments in addition to the standard points for winning or drawing a match. The bonus point system used in rugby tournaments awards 4 points for a win, 2 points for a draw, a try bonus point for teams that score four or more tries in a match, and a losing bonus point for teams that lose a match by seven or fewer points.
