Duckworth Lewis Method Target Calculator, Detailed Guide to DLS Method

Curious about the Duckworth Lewis Method Target calculator or DLS Method? Well, imagine you’re watching a cricket match, and rain decides to join the game. What happens to the target score? That’s where the Duckworth-Lewis-Stern Method steps in. In simple terms, it’s like a recalibration tool for match targets when rain throws a curveball. Our guide breaks it down, making it easy to understand. Whether you’re a cricket pro or just getting into the game, this method is a game-changer. Let’s dive in and demystify the Duckworth Lewis Method Target or DLS method target together!

What is Duckworth Lewis Method?

The Duckworth Lewis Method Target is a system used in cricket to adjust the target score in rain-affected matches. It ensures a fair and revised target for the team batting second, considering the impact of weather interruptions on the game.

When was Duckworth Lewis Method discovered?

The Duckworth-Lewis Method, created by statisticians Frank Duckworth and Tony Lewis in 1997, revolutionized the way target scores are adjusted in rain-affected limited-overs cricket matches. Over the years, the method has evolved, and the latest version, known as DLS (Duckworth-Lewis-Stern), was introduced in 2014. This innovative approach ensures a fair and accurate recalculation of target scores, accounting for weather interruptions during matches. The DLS Method has become an integral part of the sport, providing a standardized and reliable way to handle the complexities of adjusting targets in cricket games affected by adverse weather conditions.

When was the DLS method first used or Implemented?

Back in the day, in 1997, on a crisp January 1, the world of cricket witnessed a groundbreaking moment when the Duckworth Lewis Method (DLS) made its international debut. It was in the second match of the Zimbabwe versus England ODI series that this revolutionary method was put to the test, and boy, did it deliver! Zimbabwe emerged victorious by a narrow margin of seven runs, proving the effectiveness of the DLS in determining fair scores even when rain throws a wrench into the game plan. The International Cricket Council (ICC) recognized the brilliance of the DLS and officially adopted it in 1999 as the standard method for calculating revised targets in rain-shortened one-day matches. And thus, the DLS became an integral part of cricket’s ever-evolving landscape, ensuring that even when Mother Nature plays spoilsport, the spirit of fair play remains alive on the cricket field.

How does the Duckworth Lewis method work?

The Duckworth Lewis Method (DLS) is a complex algorithm used to calculate a revised target score in rain-affected one-day cricket matches. It aims to ensure fairness for both teams by adjusting the target based on the amount of overs each team has faced.

The DLS method considers two main factors:

  1. Overs: The number of overs available to each team is a crucial resource. A team with more overs has more opportunities to score runs, giving them an advantage. The DLS method adjusts the target based on the difference in overs faced by each team.
  2. Wickets: The number of wickets in hand is another significant resource. A team with more wickets has more batsmen to bat, extending their potential scoring ability. The DLS method takes into account the difference in wickets lost by each team.

The DLS method assigns a percentage value to each combination of overs and wickets left. These percentages are based on historical data and statistical analysis of how teams have fared in different situations.

To calculate the revised target, the DLS method compares the percentage of resources available to each team. The team batting second (Batting Team) is assigned a target that is proportionately lower than the score of the team batting first (Batting Team 1) if they have played fewer overs or have lost more wickets.

Here’s a simplified explanation of the DLS method:

  1. Calculate the percentages of resources available to each team: For each team, calculate the percentage of overs completed and the percentage of wickets remaining. These percentages are compared to determine the overall resource percentage for each team.
  2. Adjust the target based on resource percentages: Multiply the original target score by the resource percentage of the Batting Team. This gives the revised target score.

The DLS method is a sophisticated and constantly evolving algorithm that aims to provide a fair and equitable outcome for both teams in rain-affected cricket matches. It has been instrumental in ensuring the integrity of the game and maintaining the competitive balance, even when unforeseen circumstances disrupt the natural flow of a match.

What is the formula for DLS method?

Here is the DLS method formula and an example of how to use it:

DLS Method Formula:

Revised Target Score = Original Target Score * Resource Percentage of Batting Team

Calculating Resource Percentage of Batting Team:

Resource Percentage of Batting Team = (Remaining Overs/Total Overs)*(Remaining Wickets/Total Wickets)

Explanation of the Formula:

  • Original Target Score: This is the target score set for the team batting first (Batting Team 1) before any rain interruptions.
  • Resource Percentage of Batting Team: This is a percentage value that represents the remaining resources available to the team batting second (Batting Team) compared to the team batting first. It takes into account the percentage of overs completed and the percentage of wickets remaining for the Batting Team.


Let’s say that the team batting first (Batting Team 1) sets a target score of 200 runs. However, rain interrupts the match after they have only completed 40 overs and lost 5 wickets. The team batting second (Batting Team 2) is then given a revised target score.

To calculate the revised target score, we need to determine the Resource Percentage of Batting Team 2. We can do this by looking at the tables provided by the International Cricket Council (ICC). Based on the information we have, the Resource Percentage of Batting Team 2 is approximately 79%.

Now we can insert the values into the formula:

Revised Target Score = 200 runs * 79%

Revised Target Score = 158 runs

Therefore, the revised target for Batting Team 2 is 158 runs. This is because they have used 79% of the resources available to Batting Team 1.

It’s important to note that the DLS method formula is not publicly available, and the exact calculations are done by a proprietary software program used by the ICC. However, the simplified formula and example above can give you a general understanding of how the DLS works.

Truth Behind Duckworth Lewis Stern Method Calculator or DLS Calculator:

So, if you are on the lookout for DLS (Duckworth-Lewis-Stern) calculator online apps. There are these unofficial calculator apps floating around on the web. Just do a quick Google search, and you will find a bunch.

Now, the official software for calculating DLS scores is a special one called Coda. But here’s the thing – it’s not something you can just download like your regular apps. Nope, it’s usually given out to clubs or teams by cricketing boards, along with some instructions on how to use it.

I found this old post from Cricinfo on The Duckworth Lewis Method 1999 talking about CODA, the program for scoring D/L targets. The catch? You can’t buy it if you’re not a cricket big shot. Fast forward to 2001, the ICC took over CODA, making it even more exclusive.

So, in a nutshell – yes, the ICC has this cool software, but it’s not like your everyday apps you can grab.

Now, here’s the thing about online DLS calculators: they might not always have the latest version. The ICC can make changes to the DLS method formula whenever they want, and these updates might not show up in all online calculators.

If you’re ever in doubt about whether an online DLS calculator is spot-on, you can check the ICC’s website for the latest formula. Or shoot a message to the folks who made the calculator and ask about their update policy.

To sum it up, online DLS method calculators are handy, but it’s smart to double-check with the official formula or chat with a cricket expert to be sure you’re on the right track. You can also check our net run rate calculator which is exclusively developed for the cricket lovers.
