Chess Elo Calculator

Enter the results of your chess games into the fields below to calculate your new Fide rating. If you already have an official rating, this calculator reveals the rating change based on the results of your latest games. Otherwise, your initial rating is calculated. In addition to the new elo, this calculator also reveals your performance rating and your expected score. The results of this calculator are valid for any type of Fide rated games, including classical games with long time control as well as rapid and blitz games. Please note the following points regarding the calculation of your rating:

• According to the new Fide regulations, there is a rating floor at 1400. If your rating drops below that value, you become unrated.
• If you are unrated, you need to play at least 5 games against rated opponents and score at least 0.5 points out of these games to get your first official rating.
• Games against unrated opponents are not included into the calculation, so you do not need to enter these games in 'Step 2' of the form below.
