Badminton player ratings
How our rating works, in charts.
One number for how well a player is playing, worked out from who they beat and who beat them, in every senior draw result in order. It turns into the chance either side wins a match. It is our own model, never an official BWF figure.

Two ratings, one chance
Set two ratings and see what the model expects, the chance we publish, the fair prices, and how far player A would move with a win or a loss.
Ratings move on the Elo scale of 400; the chance we publish uses the fitted scale of 320. The calculation is set out in the docs.
The chance we publish
- Rating gap
- A's chance
- A's expected score (400 scale)
- Fair prices, A / B
- If A wins
- If A loses
The bigger the gap, the surer the win
The line is the chance we publish for the higher-rated side. The dots are what happened: how often the higher-rated side really won, in bands of 25 points, since 2010.

When we say 70%, about 70% win
Every match is scored with the ratings as they stood before it was played, so nothing from the match or after it leaks in.
Chance against result
Each circle is a band of matches by the favourite's chance; bigger circles hold more matches. On the dashed line, the chance came true exactly.

The closing market is sharper: it sees injuries, form within a tournament and money, and the rating sees only results. The rating is an independent second opinion, and the only one where there is no price.
How often the favourite won, every season
The line is the share of matches the rating's favourite won each year; the bars behind it are how many matches were rated.

The world's top 20, and where we rate them
The world ranking counts points from finishing places over 52 weeks; the rating counts who you beat. Where they differ, the rating is usually reacting faster to recent results.

The 2026 Arctic Open men's singles final, worked through
The most recent men's singles final we have rated, with every number the rating used.
Before and after
The steps
- The gap:
1,841.9 - 1,988.3 = -146.4. - Expected score on the 400 scale:
1 / (1 + 10^(+146.4 / 400)) = 0.301for Yushi Tanaka. - The result: Anders Antonsen won, so their score is 1 and the other's is 0.
- Each moves by K times (score minus expected):
20 × (0 - 0.301) = -6.0. - The published chance used the fitted scale of 320 instead of 400: 25.9% for Yushi Tanaka.
Only results, and the order they came in
The rating is deliberately simple. That makes it hard to game and easy to check, and it means some things are left out on purpose.
Counted
- The winner and loser of every senior draw match we hold, first round to final.
- How strong the opponent was, by their rating at that moment.
- The order of play: tournaments by start date, then round by round.
- Retirements, as the result stands.
- How many rated matches a player has had, which sets how far one result moves them.
Not counted
- The score: a three-game thriller counts the same as a rout.
- Walkovers, where no match was played.
- The tournament's level: a win counts the same at every event.
- Junior events, and qualifying rounds the draw does not show.
- Time away: a rating waits for a player's return rather than fading.
