Cricket DLS Method Calculator

Calculate revised targets using the Duckworth-Lewis-Stern (DLS) method for rain-affected cricket matches. For T20, ODI and other limited-overs formats.

⚠️ This is a simplified DLS estimator. Official DLS calculations use detailed resource tables published by ICC. Use this for educational and estimation purposes.

About this calculator

Estimate the revised target in a rain-affected limited-overs match using the Duckworth-Lewis-Stern idea. Enter Team 1's score and overs, and Team 2's overs and wickets.

This is an approximation of the method. The official calculator uses ICC's resource table. For official targets use the match officials' software.

How to use it

  1. Enter Team 1 score and overs.
  2. Enter Team 2 overs and wickets lost.
  3. Read the revised target.

The DLS idea

DLS treats a team's batting potential as resources: overs left and wickets in hand. A full innings is 100% resources. When rain cuts Team 2's resources to R2 (less than Team 1's R1), the par score is Team 1 score × R2 ÷ R1 and the revised target is that plus 1. If Team 2 has more resources than Team 1, the target is increased using G50 (the average 50-over score, about 245): T1 + G50 × (R2 − R1) ÷ 100. Resource percentages come from the official table, which changes with each edition.

Tips and common mistakes

  • The real table is more complex than a simple overs ratio.
  • Early wickets cost more resources than late ones.
  • Resources matter more than overs alone.
  • Use the official software for match results.
  • T20 uses a different G value (G20).
