DLS Calculator
The Duckworth-Lewis-Stern (DLS) method sets a fair target when rain cuts overs, by comparing each side's resources: overs left and wickets in hand. Target = Team 1's score × (R2 ÷ R1), rounded down, + 1. This DLS calculator gives the revised target and par score from the ICC's published Standard Edition table.
International matches use the ICC's DLS software, so their targets can differ from this table, most of all in high-scoring games.

How Is the DLS Target Calculated?
The method measures each side's resources: the overs left and the wickets in hand, as a percentage of a full 50-over innings. The ICC table lists this for every ball and every number of wickets down.
- Start with the resources for the overs each side was given, with no wickets down. 50 overs is 100%.
- For each stoppage, take the resources left when play stopped, minus the resources left on the restart. That is what the side lost.
- R1 is what Team 1 had. R2 is what Team 2 has.
- If R2 is less than R1, the target is Team 1's score × R2 ÷ R1, with the decimals dropped, plus 1.
- If R2 is more than R1, the target is Team 1's score + G50 × (R2 − R1) ÷ 100, rounded down, plus 1.
Worked example (ICC example 3)
Team 1 scores 250 in 50 overs, so R1 is 100%. Team 2 is 40/1 after 12 overs when rain costs 10 overs.
Left at the stoppage (38 overs, 1 down): 82.0%
Left on the restart (28 overs, 1 down): 68.8%
R2 = 100 − (82.0 − 68.8) = 86.8%
Target = 250 × 86.8 ÷ 100 = 217, plus 1 = 218 in 40 overs

What Is a DLS Par Score?
The par score is the score that ties the match if play ends at that moment. It uses the same sums as the target, without the extra run. Above par, Team 2 wins. Level with par, it is a tie. Below par, Team 1 wins.
Why wickets matter
Say Team 1 made 250 in 50 overs and Team 2 is chasing. After 25 overs, par is 98 if Team 2 is 2 down, but 168 if it is 6 down. A side on 120 would be 22 runs ahead of par in the first case and 48 behind in the second.
What Is G50 in DLS?
G50 is the average score in an uninterrupted 50-over innings. The ICC's Standard Edition uses 245 for matches involving Full Members or between first-class teams. It uses 200 for U19 and U15 internationals, women's internationals and matches between Associates.
G50 only matters when Team 2 has more resources than Team 1, which happens when rain cuts Team 1's innings. In the ICC's first example, Team 1 made 180 after losing 10 overs, so R1 is 87.5%. Team 2 had 40 overs, so R2 is 89.3%. The target is 180 + 245 × 1.8 ÷ 100, rounded down, plus 1: 185.
DLS in T20 Matches
The ICC uses the same table for T20. A 20-over innings starts with 56.6% of the resources of a 50-over innings, and G50 is not scaled down.
Say Team 1 makes 180 in 20 overs and Team 2's chase is cut to 15 overs before it starts. R1 is 56.6% and R2 is 45.2%. The target is 180 × 45.2 ÷ 56.6 = 143.7, so 144 in 15 overs. Switch the DLS calculator to T20 and press Example to see it.
Under ICC T20I playing conditions, Team 2 must face at least 5 overs for a result, unless it gets there sooner. The ICC Men's T20 World Cup 2026 rules ask for 10 overs in the semi-finals and final.
Common Rain Scenarios in Cricket
When the rain comes changes how the target moves. Knowing the patterns helps you follow session betting and live markets after a restart.
| Scenario | DLS impact |
|---|---|
Late start Match cut to 15 overs a side | Both sides get the same overs, so R1 equals R2 and the target is Team 1's score + 1. |
Rain during the chase Team 2 loses overs mid-innings | Team 2 loses the resources of the lost overs at its current wickets. Target = Team 1's score × R2 ÷ R1, rounded down, + 1. |
Team 1's innings cut short Rain at 35 overs, Team 1 on 180/4 | Team 1 used 62.4% of a full innings. If Team 2 gets 35 overs (82.7%), the target rises through G50 to 230. |
More than one stoppage Stop-start throughout the match | Each stoppage takes resources away and the target is worked out again. This calculator takes one stoppage per innings. |
Using the Par Score During a Rain Break
Runs and the required rate tell only part of the story. The par score also counts wickets in hand, which is why a side can be behind the rate and still ahead of par.
Par score first
Work out the par score before you judge a price. Use the implied probability calculator to turn odds into a percentage you can compare.
When play restarts
A revised target is set when play restarts. With the overs lost and the wickets down at the stoppage, you can work out this table's figure first.
Session markets after rain
If you follow session betting lines, compare a line after rain with the runs Team 2 needs to stay level with par.
Rain Delay Checklist
- 1. Work out the par score for the current overs and wickets.
- 2. Check whether the chasing side is ahead or behind par.
- 3. Compare the market price with your own view of the match.
- 4. Count the wickets in hand: more wickets leave more room to score.
Standard Edition vs the DLS Used in International Cricket
This DLS calculator uses the Standard Edition: the table and formulas the ICC publishes on its Duckworth-Lewis-Stern page. The ICC keeps it for matches where the DLS software cannot be run.
Top-level matches
International matches use the ICC's DLS software, the Stern Edition since 1 October 2014. The ICC says the Standard Edition stopped coping well with high scores, so gaps are most likely in high-scoring games.
Mid-over stoppages
The calculator uses the ICC's ball-by-ball figures, so 35.3 overs means 35 overs and 3 balls.
T20 matches
Same table, no rescaling. A 20-over innings starts at 56.6%, and G50 stays the same.
One stoppage per innings
The ICC method adds up the loss from every stoppage. This calculator takes one per innings, so for stop-start games rely on the target set at the ground.
DLS Calculator FAQs
What is the DLS method in cricket?
The Duckworth-Lewis-Stern (DLS) method sets a revised target when rain or bad light cuts overs. It compares the run-scoring resources each side had: overs left and wickets in hand. Top-level matches have used the Stern Edition, run by computer, since 1 October 2014.
How is the DLS target calculated?
Find each side's resources in the table: R1 for Team 1 and R2 for Team 2. If R2 is less than R1, the target is Team 1's score × R2 ÷ R1, with the decimals dropped, plus 1. If R2 is more than R1, the target is Team 1's score + G50 × (R2 − R1) ÷ 100, rounded down, plus 1.
What is a DLS par score?
The par score is the score that ties the match if play ends at that moment. Above par, Team 2 wins. Level with par, it is a tie. Below par, Team 1 wins. The target is always par plus one run.
What is G50 in DLS?
G50 is the average score in an uninterrupted 50-over innings. The ICC's Standard Edition uses 245 for matches involving Full Members or between first-class teams, and 200 for U19 and U15 internationals, women's internationals and matches between Associates. It is used only when Team 2 has more resources than Team 1.
Is this the same target as in international matches?
Not always. International matches use the ICC's DLS software. This calculator uses the Standard Edition table that the ICC publishes for use when that software is not available, so the target shown on TV can differ. The ICC says the Standard Edition stopped coping well with high-scoring matches, so expect bigger gaps there.
How does DLS work in T20 matches?
The same table is used. A 20-over innings starts with 56.6% of a 50-over innings' resources, and the same G50 applies. If Team 1 makes 180 in 20 overs and Team 2's chase is cut to 15 overs before it starts, the target is 180 × 45.2 ÷ 56.6 = 143.7, so 144.
What is the minimum number of overs for a DLS result?
Under the ICC's playing conditions, Team 2 must face at least 20 overs in an ODI and 5 overs in a T20I, unless a result comes sooner. The ICC Men's T20 World Cup 2026 rules ask for 10 overs in the semi-finals and final.
Why do wickets affect the DLS target so much?
Overs are worth little without wickets to use them. With 25 overs left, a side that is 1 down still has 63.9% of a full innings' resources; a side that is 5 down has only 42.2%.
What is the difference between DLS and Net Run Rate?
DLS revises the target within a single rain-affected match. NRR separates teams in a tournament table. Different problems, different tools. Use our Net Run Rate Calculator for standings and playoff qualification math.
Can the par score tell me who will win?
No. Par tells you which side is ahead if play ends at that moment, counting wickets as well as runs. The ICC stresses that the method does not try to predict the result at a stoppage.
