What is the Chess Performance Rating & How does it work?

A chess player’s performance rating reflects how strongly they performed against the field in a specific tournament. It is not a permanent rating but a snapshot that compares the player’s results to the average strength of their opponents.

FIDE defines the performance rating (Rp) using the average opponent rating (Ro) and the net score difference between wins and losses. The more wins you achieve against higher‑rated opponents, the larger the boost to your performance rating.

The calculation is straightforward: you add a correction factor to the average opponent rating. This factor grows with the surplus of wins over losses and shrinks when you lose more games.

Rp = Ro + frac{800,(W – L)}{N}
Rp = performance rating, Ro = average opponent rating, W = number of wins, L = number of losses, N = total games played
