🌧️ Duckworth Lewis Calculator
Estimate DLS par scores when rain interrupts limited-overs matches.
Team 1 – First Innings
Team 2 – Chasing
Team 1 Resource Remaining
54.0% resources remaining when innings closed.
Team 2 Resource Remaining
54.0% of resources available at interruption.
Par Score
0
Runs Team 2 should be on after current interruption for scores to be level.
How to Use This Calculator
Enter match overs
Typically 50 for ODIs, 20 for T20s (note: this calculator is tuned for 50-over DLS).
Input Team 1 innings
Runs, overs completed, wickets lost.
Input Team 2 current status
Runs so far, overs completed, wickets lost when rain stops play.
Review par score
Compare Team 2 total with par to judge the result if the match cannot resume.
Formula (Approximate)
Par Score ≈ Team 1 Runs × (Team 2 Resource ÷ Team 1 Resource)
The official DLS method uses lookup tables for resources left based on overs remaining and wickets lost. This calculator uses a simplified resource model to approximate par scores when weather interrupts play.
Variables
- Team 1 Resource: % resources used
- Team 2 Resource: % resources available
- Par Score: Target runs adjusted for resources
Example
Team 1: 275/7 in 50 overs (resource 100%). Team 2: rain at 26.2 overs, 3 wickets down (resource ~63%). Par ≈ 275 × (63 ÷ 100) ≈ 173. If Team 2 has 180, they are ahead; if 165, they trail.
Frequently Asked Questions
Is this the official DLS calculation?
No. This tool uses an approximate resource model for quick scenarios. Official matches use the ICC's proprietary DLS software.
Can this handle multiple interruptions?
This version focuses on a single interruption scenario. For multiple stoppages, official DLS systems recalculate after each break.
Why do resources depend on wickets?
Losing wickets reduces scoring potential. DLS reduces resource percentage as wickets fall, reflecting lower run-scoring capacity.
What about T20 matches?
The shorter format uses different tables with lower thresholds. For a precise T20 calculation, official DLS software is recommended.
How do I interpret the par score?
If Team 2’s score exceeds par when rain ends play, they are declared winners; below par, they lose; equal means a tie.
