🌍 ICC Team Rating Calculator
Simulate how team ratings shift after wins, losses, or ties against different opponents.
ICC weights newer matches more heavily until 30 matches are reached.
Points Earned This Match
50.0
Match Weight
1.00 (Points count towards rating)
Projected New Rating
50.0
Based on the match result and opponent strength, your rating would move to this value.
How to Use This Calculator
Enter current rating
Use the official ICC rating prior to the fixture.
Provide matches counted
Matches forming the current rating (ICC weights newer matches up to 30).
Add opponent rating
Opponent strength influences points earned.
Select result
Win, tie/no-result, or loss—see how your rating changes.
Formula (Simplified)
New Rating = (Current Rating × Matches + Match Points × Weight) ÷ (Matches + Weight)
Match points are calculated from the opponent rating plus bonuses for wins (+50) or penalties for losses (−50). Weight depends on how many matches are already counted towards the rating.
Example
Current rating 112 after 28 matches. Beat an opponent rated 105. Match points = 105 + 50 = 155. Weight = 1 (still under 30 matches). New rating ≈ (112 × 28 + 155 × 1) ÷ 29 = 113.5.
Variables
- Current rating: Team’s pre-match ICC rating
- Matches: Weighted matches forming rating
- Match weight: 1 if ≤ 30 matches, else 0.5
Understanding ICC Ratings
ICC ratings are moving averages that reward wins against stronger opponents and penalize losses to lower-ranked teams. Newer matches carry more weight to reflect current form.
Key Points
- A series result is treated one match at a time; ratings update after each fixture.
- Winning away or against higher-rated opponents yields larger rating gains.
- Ratings can fluctuate sharply early on, then stabilize beyond 30 matches.
Apply Insights
- Project ranking movements after upcoming fixtures.
- Assess how many wins are needed to climb the table.
- Evaluate risk of rating drops when facing lower-ranked teams.
Frequently Asked Questions
Is this the exact ICC formula?
It’s a simplified model capturing weighting and opponent strength. The ICC formula has additional nuances, but this provides close projections.
What about multi-match series?
Enter each match sequentially. Ratings update after every result within the series.
Do ties and no-results count the same?
Yes. Both yield opponent rating points (no +50 bonus) and carry full match weight.
How often are ratings published?
ICC updates ratings after each international match. This calculator helps forecast moves before official publication.
Can I use this for women’s rankings?
Yes. The rating mechanics are the same; just input the appropriate team ratings.
