US Chess Rating Calculator

Estimate your new US Chess rating after a tournament. Enter your current information and each opponent's rating and result.

1. Your current rating information

Current rating Your rating before this event.

Previously rated games The total games on which this rating is based.

Previous-game history Most players should select “Mix of results.”

Rating floor, if known Leave at 100 when unsure.

Rating system Each US Chess rating system is calculated separately.

Event calculation Special setting for high-rated players in dual-rated events.

Apply the US Chess bonus formula when eligible. Uncheck this for a match, an event with fewer than three games, or an event whose repeated-opponent structure makes bonus points ineligible.

Actual results can differ because US Chess may use post-event opponent ratings, unrounded internal ratings, personal or prize-based floors, repeated-opponent rules, reratings, and information unavailable to this calculator.
