About Duckworth Lewis Calculator

DuckworthLewisCalculator.com is an independent collection of practical cricket scoring calculators and explanations. Our goal is to make cricket statistics easy to understand, whether you are watching a match, keeping score, or learning how a calculation works.

What you can calculate

Our tools include run rate, required run rate, net run rate, batting strike rate, bowling economy, projected score, and overs-to-balls conversion. The homepage provides a historical Duckworth–Lewis Standard Edition calculation for simple rain-interruption scenarios.

Accuracy and limitations

We use published cricket rules and reference documents where relevant and explain the formulas behind our calculations. The historical Duckworth–Lewis Standard Edition tool is not a substitute for current professional DLS software, and no result from this site overrides match officials or a tournament’s playing conditions.

Independent website

This website is independently operated. It is not affiliated with or endorsed by the International Cricket Council (ICC), national cricket boards, or any tournament.

Feedback and corrections

If you identify a calculation issue, please include the input values, your expected result and a reliable rule or source. See our Calculation Methodology and Editorial Policy for our approach.
