Net Run Rate (NRR) is the difference between a team’s attacking (scoring) efficiency and how quickly/slowly they make runs to their opponents in a tournament. It is used to determine the position of teams in terms of points parity. Below is the formula, step-by-step example, and actual calculations related to Bangladesh—Super Four.
1) Net Run Rate Formula (in simple terms)
Each team’s net run rate is calculated as the difference between these two parts:
- Total runs scored by that team in the tournament / Total overs (one over batted)
- Total runs conceded by that team to its opponents in the tournament / Total overs (one over bowled)
Formula (Abbreviated):
NRR = (Total runs scored / Total overs faced) − (Total runs conceded / Total overs bowled).
Note: If a team is all-out in an innings or the boundary or rain rule applies, the over count and in some cases the rules may differ, but generally the above formula applies. In the event of a wicket-shortening or rain-adjustment (DLS), the calculation is adjusted according to the official Laws of Cricket.
2) Real example — Bangladesh (Asia Cup 2025, Group-B)
(Source and scorecard: Taken from Cricbuzz and ESPNcricinfo — Recent matches: Bangladesh vs Hong Kong, Sri Lanka, Afghanistan).
Overall scoring data for Bangladesh’s three innings of group games (see Cricbuzz/SPN scorecard):
Bangladesh vs Hong Kong
- Hong Kong: 143/7 (20.0 overs)
- Bangladesh: 144/3 (17.4 overs) → Win by chase.
Bangladesh vs Sri Lanka
- Bangladesh: 139/5 (20.0 overs)
- Sri Lanka: 140/4 (14.4 overs) → Bangladesh lost.
Bangladesh vs Afghanistan
- Bangladesh: 154/5 (20.0 overs)
- Afghanistan: 146/10 (20.0 overs) → Bangladesh won (won by 8 runs).
Adding these together (up to group):
Total Run Score (Bangladesh scored): 144 + 139 + 154 = 437 runs
Total overs (Bangladesh faced while batting):
- 17.4 overs = 17 + 4/6 = 17.6666667 overs
- 20 overs + 20 overs = 40 overs
- Total = 17.6666667 + 20 + 20 = 57.6666667 overs
Total runs conceded (Bangladesh): 143 + 140 + 146 = 429 runs
Total overs (Bangladesh bowled): 20 + 14.4 + 20 =
- 14.4 overs = 14 + 4/6 = 14.6666667
- Total = 20 + 14.6666667 + 20 = 54.6666667 overs
Now calculate NRR:
- Bangladesh’s runs/over = 437 ÷ 57.6666667 ≈ 7.5790
- Runs/over conceded to Bangladesh = 429 ÷ 54.6666667 ≈ 7.8485
- So NRR = 7.5790 − 7.8485 = −0.2695 ≈ −0.270
This calculation matches the NRR (−0.270) shown on Cricbuzz. Therefore, our calculation is verifiable and accurate.
3) Now the question is — What is Bangladesh’s estimate of reaching the 2025 Super Four? (Status and Probability)
(Source: Cricbuzz points table and recent updates) — Current situation: Bangladesh has 2 wins, 1 loss = 4 points and NRR ≈ −0.270 in 3 matches in the group. Sri Lanka (2 wins, 0 losses, points 4 and NRR positive) is leading the group. The result-dependency and NRR-situation of other teams is changing rapidly.
General rules (based on tournament rules):
- Typically, the tie-breakers between teams on the same points are (1) head-to-head results, (2) net run rate. The application may vary in different tournaments — in the Asia Cup, NRR is used as the main tiebreaker if head-to-head results are equal.
4) Live data status for the last 4 hours (updated)
I checked Cricbuzz and live scorecards and found that Bangladesh won the recent Bangladesh vs Afghanistan match (won by 8 runs), and the Cricbuzz points table now shows Bangladesh with 4 points and NRR −0.270. The Cricbuzz and live reports have been updated in the last few hours; hence the above calculations and decisions are based on the latest Cricbuzz scorecard and points table.
The final decider for Bangladesh is the Sri Lanka vs Afghanistan match. Bangladesh’s Super Four journey depends on the result of this match. If Sri Lanka wins, Bangladesh will reach the next round safely. But if Afghanistan wins, points will be equal and then net run rate will be the main factor. Since Bangladesh’s current net run rate is negative, Bangladesh may fall behind if Afghanistan wins big. So, Bangladesh fans are now fully focused on the Sri Lanka-Afghanistan match, because this match will ultimately decide whether Bangladesh will go to the Super Four or be knocked out of the tournament.
