The ICC Men's T20I Team Rankings decide which nation sits at No. 1, and the movement after each series is followed closely by fans. This calculator applies the published ICC ratings-gap rules to a single match: enter both teams' ratings and the result, and it shows the ranking points each team earns from that game. Add your team's current points and matches to estimate how its rating could move.
How to use the ICC T20I team points calculator
- Enter your team's rating and the opponent's rating before the match. You can find these on the ICC team rankings page.
- Choose the result for your team: win, tie or loss.
- Optionally enter your team's current points and matches to see an estimated new rating.
- Read the points earned by each side, the ratings gap and the estimated change.
How ICC team ratings work
Each team in the table has a points total and a match count. Its rating = points ÷ matches. After every match, both teams add one to their match count and add a number of points to their total. The number of points depends on the result and on how far apart the two teams were rated before the game.
When the ratings are less than 40 points apart
- Winner earns: the opponent's rating + 50
- Loser earns: the opponent's rating − 50
- Tie: each team earns the opponent's rating
When the ratings are 40 or more points apart
- Stronger team wins: stronger team earns its own rating + 10; weaker team earns its own rating − 10
- Weaker team wins: weaker team earns its own rating + 90; stronger team earns its own rating − 90
- Tie: stronger team earns its own rating − 40; weaker team earns its own rating + 40
The logic is simple. If a strong team beats a much weaker one, the result was expected, so the ratings barely move. An upset moves them a lot.
Worked example
A closely rated contest
- Ratings gap
- 15 (under 40)
- Team A earns
- 245 + 50 = 295 points
- Team B earns
- 260 − 50 = 210 points
- Team A new rating
- (11,700 + 295) ÷ 46 = 260.8
Team A's rating rises by less than a point, because a single match is a small part of a 45-match record.
Worked example
An upset
- Ratings gap
- 52 (40 or more)
- Team C earns
- 210 + 90 = 300 points
- Team D earns
- 262 − 90 = 172 points
- Team C new rating
- (6,300 + 300) ÷ 31 = 212.9
An upset is worth far more to the weaker team than a routine win is to the stronger one.
Why the official table can differ from this estimate
The ICC does not simply add every match ever played. Results are counted over a rolling period of roughly three to four years, and more recent matches carry more weight than older ones. Once a year, the oldest matches drop out and the weights shift, which is why rankings can change in May without a ball being bowled. This calculator shows the effect of one match on unweighted totals, which is a good guide to the direction and rough size of a change, but the official numbers come from the ICC.
Common questions about ICC team rankings
- Do margins of victory count? No. Only the result matters, not whether a team won by one run or 100.
- Do all T20Is count? Since the ICC granted T20I status to all its members in 2019, T20Is between all member nations count towards the rankings.
- Are Test, ODI and T20I rankings calculated the same way? ODI and T20I rankings use this match-by-match method. Test rankings work on series results and have a different structure.
Common mistakes
- Using ratings from after the match. Use both teams' ratings before the game.
- Getting the gap rule backwards. When the gap is 40 or more, points are based on each team's own rating, not the opponent's.
- Expecting big moves from one win. Teams with many matches move slowly.
