Duckworth-Lewis (D/L)

Calculate revised targets for rain-affected cricket matches using the simplified Standard Edition method.

Match Parameters

Note: This tool uses the Standard Edition approximation. It assumes Team 1 completed 50 overs and Team 2 faces a reduced number of overs with 10 wickets in hand.
Team 1 Score (1st Innings)

Understanding the DLS Method

The Duckworth-Lewis-Stern (DLS) method is a mathematical formulation designed to calculate the target score for the team batting second in a limited-overs cricket match interrupted by weather or other circumstances.

Why is it needed?

Cricket is a game of resources: Overs and Wickets. When a match is shortened, the team batting second has fewer overs but typically still has all 10 wickets. Simply reducing the target proportionally (Run Rate) is unfair because they can take more risks with wickets to score faster. DLS adjusts the target to keep the difficulty equal.

How it works

The method assigns a "resource percentage" to the overs and wickets remaining. If a team loses overs, they lose resources. The target is adjusted based on the resources available to both teams.

Standard vs. Professional Edition

There are two versions of DLS:

  • Standard Edition: Used in recreational and lower-level cricket (and this calculator). It uses a single table of resource percentages.
  • Professional Edition (DLS): Used in international cricket. It uses complex software to account for high-scoring trends and is kept confidential by the ICC.

This calculator is an educational tool based on publicly available formula approximations and should not be used for official match refereeing without verification.
