Sobre esta calculadora

This calculator provides an ELO-based preliminary calculation for ECF rating changes. The official ECF rating is finalised by the English Chess Federation.

Para jogadores sem ECF

For players without an ECF rating, the tool can show a starting performance based on results against rated opponents. The official starting rating is subject to ECF rules.

Como funciona o rating ECF

Pontuação esperada:

E = 1 / (1 + 10^((Rb - Ra) / 400))

Novo rating:

R'a = Ra + K × (S - E)

Simplified coefficients: K=40 for fewer than 30 games, K=20 for established players. The official ECF system follows standard ELO calculations.
