Understanding your rating
What Is Dynamic NTRP?
Your published NTRP level is a snapshot. Behind it sits a continuously updated rating that moves with every match you play — often called Dynamic NTRP.
What Dynamic NTRP means
Dynamic NTRP refers to the internal, continuously calculated rating the USTA maintains for computer-rated players. Unlike your published level, which is expressed in half-point steps such as 3.5 or 4.0, the dynamic rating is far more granular and updates as you record results.
Dynamic rating vs published year-end rating
The year-end rating you eventually see is derived from your dynamic rating at the close of the season. Think of the dynamic value as the live figure and the published level as the periodic, rounded report of where it landed.
How match results influence rating
Results move your dynamic rating based on how you performed relative to expectation — not simply whether you won. A result that beats expectations tends to apply upward pressure; a result that falls short tends to apply downward pressure.
Why opponent strength matters
A win over a much stronger opponent carries different information than a win over a much weaker one. The rating gap sets the expectation against which your actual performance is measured.
Why match score matters
Two wins are not equal. Winning 6–1, 6–2 signals a more dominant performance than escaping 7–6, 7–6, and score-sensitive systems reflect that difference.

Why third-party estimates can differ
Because the official dynamic value is not publicly exposed, third-party sites build their own estimates. These can be directionally useful, but they are approximations and will not match USTA's internal figure exactly.
What USTA publicly explains
The USTA publicly describes the general principles: ratings are computer-calculated from match results, opponent strength and scores matter, and year-end ratings are produced from the dynamic figure.
What remains unpublished
The complete formula — exact weightings, decay, reliability handling and thresholds — is not published. That is why any tool, including this one, can only offer transparent estimates rather than the official calculation.
Tennis Rating Lab is an independent estimation and educational tool. It is not affiliated with or endorsed by USTA or UTR Sports. USTA does not publish its complete Dynamic NTRP algorithm, so calculations shown here are estimates and should not be interpreted as official ratings.
