USATT Rating Calculator – Accurate Table Tennis Ratings

This tool calculates your new USATT rating based on match outcomes.

USATT Rating Calculator Explanation

This calculator helps you estimate your new USATT rating based on your current rating, your opponent’s rating, and your match outcome. Enter your current USATT rating, your opponent’s USATT rating, and select whether you won or lost the match. The calculator will then display your new estimated rating.

How to Use

  1. Enter your current USATT rating in the “Current USATT Rating” field.
  2. Enter your opponent’s USATT rating in the “Opponent’s USATT Rating” field.
  3. Select the match outcome (Win or Loss).
  4. Click the “Calculate” button to see the result in the “Result” field.

How It Calculates

The calculator uses a standard Elo-based formula to calculate the new rating:

  1. If your rating is less than 2100, a K-factor of 25 is used.
  2. If your rating is between 2100 and 2399, a K-factor of 50 is used.
  3. If your rating is 2400 or higher, a K-factor of 75 is used.
  4. The expected outcome is calculated based on the rating difference between you and your opponent.
  5. The rating change is determined based on whether you won or lost the match and the expected outcome.
