DLS Calculator (Duckworth-Lewis-Stern Method)
The DLS (Duckworth-Lewis-Stern) calculator works out the revised target and the par score for the team batting second when rain or another interruption shortens a limited-overs match. Enter Team 1's score and the overs lost; the result comes from the ICC's published Standard Edition table.
Result
Enter Team 1's score to see the revised target.
Uses the ICC's published Standard Edition table. The ICC's own Professional Edition software can differ by a few runs.
What is the DLS method?
When rain cuts a limited-overs match short, the ICC uses the DLS method to keep the contest fair for both sides. It does not simply scale by the overs lost, because the last overs of an innings are worth far more when ten wickets are in hand, and every wicket that falls lowers the value of the overs that remain.
That value is called a resource: the percentage of the run-scoring potential of a full 50-over, ten-wicket innings that a side still has, given the overs left and the wickets in hand.
How to use this calculator
Enter Team 1's score. If play was interrupted in either innings, add each stoppage: the overs left when play stopped, the wickets lost at that moment, and the overs left when play resumed (0 if the innings ended). Also enter the overs Team 2 were given at the start of their innings.
You get the revised target, the par score and the working for every step. You can also enter Team 2's score at any point of the chase to see whether they are ahead of or behind par.
A worked ICC example
In a 50-over one-day international, Team 1 score 250 from their 50 overs. Team 2 have faced 12 overs and are 40/1 when play stops and 10 overs are lost.
At the stoppage, 38 overs are left with 1 wicket down: 82.0% of resources. When play resumes, 28 overs are left: 68.8%. Resources lost: 82.0 − 68.8 = 13.2%. Team 2's resources are R2 = 100 − 13.2 = 86.8%, against R1 = 100% for Team 1.
R2 is lower, so the target is 250 × 86.8 ÷ 100 = 217 (rounded down), plus 1 = 218. Team 2 need a further 178 runs from 28 overs.

Frequently asked questions
What does DLS stand for in cricket?
DLS stands for Duckworth-Lewis-Stern. It is the ICC's method for setting a fair revised target for the team batting second when a limited-overs match is shortened by rain or another interruption. It was devised by the statisticians Frank Duckworth and Tony Lewis and has been maintained by Steven Stern since 2014.
How does the DLS method work?
Every side starts an innings with a share of the run-scoring resources of a full 50-over innings, and that share depends on two things: the overs still to be bowled and the wickets in hand. Whatever resources an interruption removes are subtracted, the two teams' resources are compared, and Team 2's target is adjusted in that proportion.
How do you calculate the DLS target?
If Team 2's resources (R2) are lower than Team 1's (R1), the target is Team 1's score × R2 ÷ R1, rounded down, plus 1. If R2 is higher, the target is Team 1's score + (R2 − R1) × G50 ÷ 100, rounded down, plus 1. If the two are equal, the target is Team 1's score plus 1.
What is the par score in DLS?
The par score is the score that would tie the match, one run below the target. If the match ends early with Team 2 batting, their score is compared with the par score at that moment: above it and Team 2 win, equal and the match is tied, below it and Team 1 win.
What is G50 in DLS?
G50 is the average total score in a 50-over innings, used to convert extra resources into extra runs. Under the ICC regulations it is 245 for matches involving ICC full members and for first-class cricket, and 200 for women's, under-19, under-15 and associate-nation internationals.
Is this calculator the same as the ICC's DLS software?
Not exactly. The ICC uses its Professional Edition software, which also takes account of how fast the teams score. This calculator uses the ICC's published Standard Edition table, so its figures can differ from an official result by a few runs.
How do I enter overs in this calculator?
Use cricket notation: the digit after the point is balls. 12.3 means 12 overs and 3 balls, and 12.6 is not valid.
Does DLS apply in T20 cricket too?
Yes, with the same table and the same method. Under the ICC playing conditions a result needs at least 5 overs per side in a T20 international and at least 20 overs per side in a one-day international; leagues set their own minimum.
