Duckworth Lewis Calculator
Duckworth–Lewis (DLS) Calculator
Disclaimer: This tool uses a smooth, monotonic DLS-style resource approximation for educational use.
For official scoring, replace the resource function via the RESOURCE_HOOK in the script below.
Use our Duckworth–Lewis Calculator to quickly check the revised target or par score in rain-affected ODIs and T20s. Enter the first-innings total, overs available, overs used, and wickets in hand. You’ll instantly see the adjusted target your team needs after the interruption.
- Par score for the chasing side at the current point
- Revised target after overs are reduced
- Clear context on resources remaining (overs + wickets)
Why DLS Matters in Limited-Overs Cricket
The DLS method prevents unfair advantages when play is lost. It accounts for two key resources: overs remaining and wickets in hand. That’s more realistic than a simple run-rate approach and helps keep the contest balanced.
- ODI matches (50 overs): targets are revised as overs vanish due to weather/light.
- T20 matches (20 overs): every ball matters—DLS recalculates pressure precisely.
- Multiple interruptions: the method can handle more than one stoppage in play.
How to Use the Duckworth–Lewis Calculator
- Enter the Team A total and the originally scheduled overs.
- For Team B, enter overs faced, wickets in hand, and the new total overs after interruption(s).
- Click calculate to see the par score and any revised target.
The output shows if the chasing team is ahead or behind par at the stoppage, plus what they’ll need once the innings resumes.
Real-World Use Cases
Broadcasters, analysts, coaches, and fans lean on DLS whenever rain changes the chase. It helps answer key questions: Are we above par right now? What target will apply after the break? How many runs do we need in the remaining overs?
Key Takeaway
The Duckworth–Lewis Calculator gives fast, transparent targets that reflect the match state. Whether you’re tracking a live ODI or a T20 thriller, it makes rain-affected chases simpler to follow.
