What is the Duckworth Lewis (DLS) method?
The Duckworth–Lewis–Stern (DLS) method sets a fair target when rain or bad light shortens a limited-overs match. It doesn’t simply scale by overs. It measures resources, the combination of overs left and wickets in hand, so a team that loses overs with all 10 wickets intact is compensated more than a team that was already 8 down.
The quick formula: if Team 2 has fewer resources (R2 < R1), target = Team 1 score × R2 ÷ R1, rounded down, + 1. If Team 2 has more (R2 > R1), target = Team 1 score + (R2 − R1) × G50 ÷ 100, rounded down, + 1. The par score is the same calculation without the +1, and Team 2 wins an abandoned match if they are above it.
How to use the DLS calculator
- Choose the format: T20, ODI, T10, The Hundred (entered in balls) or a custom number of overs, such as a 40- or 45-over club match.
- Pick the G50: 245 for men’s internationals and first-class teams, or 200 for women’s ODIs, ICC Associates and Under-15 internationals. For club cricket, use your league’s average 50-over first-innings score.
- Enter Team 1’s innings: their final score and every rain break, with the overs bowled, wickets down and overs lost at each one.
- Enter Team 2’s chase: any interruptions, plus the live score, overs and wickets if you want the current par score.
- Read the scoreboard: the revised target, par score, runs needed, required rate and the result if the match has been called off. The par grid shows where Team 2 needs to be after every over.
The DLS formula, step by step
Resource at a stoppage = Table(overs left, wickets lost)
Resource lost = Table(before) − Table(after overs are cut)
R1 = Table(scheduled overs, 0) − resources Team 1 lost
R2 = Table(overs at start of chase, 0) − resources Team 2 lost
R2 < R1 : Target = ⌊ S × R2 / R1 ⌋ + 1
R2 = R1 : Target = S + 1
R2 > R1 : Target = ⌊ S + (R2 − R1) × G50 / 100 ⌋ + 1
Par score (abandoned) = same formula with resources used so far, no +1
S is Team 1’s score. ⌊ ⌋ means drop the decimals. G50 is used only when Team 2 has more resources than Team 1. That usually happens when Team 1’s innings was cut short without warning and they batted as though they had the full overs.
One table covers every format. The ICC’s 2018 review analysed 700 ODIs and 428 T20Is and found that resource usage is essentially identical across formats. That’s why a 20-over innings simply starts at the 20-overs-left row of the table (56.6%) instead of 100%.
Worked examples (T20 and ODI)
T20Rain cuts the chase from 20 to 12 overs
Team A make 160 in 20 overs, so R1 = 56.6%. Team B are 62/2 after 8 overs when rain arrives and 8 overs are lost. Their resources at the stoppage were 35.8% (12 overs left, 2 down). After the cut, 4 overs are left, worth 13.7%, so they lose 22.1%. R2 = 56.6 − 22.1 = 34.5%.
Target = 160 × 34.5 ÷ 56.6 = 97.53 → 98 to win in 12 overs, so 36 more from 24 balls. This is the calculator’s default example.
ODIMatch abandoned during the chase (par score)
Team A make 200 in 50 overs. Team B are 115/4 after 30 overs when the match is abandoned. With 20 overs left and 4 down, Team B still had 44.6% of their resources, so they used 100 − 44.6 = 55.4%. Par = 200 × 0.554 = 110.8 → 110. Team B are 5 ahead, so Team B win by 5 runs (DLS method), the same answer as the ECB’s official worked example.
ODITeam 1’s innings interrupted (G50 applies)
Team A are 79/3 after 20 overs when 20 overs are lost, 10 per side. Their resources fall from 61.6% (30 overs left, 3 down) to 49.1% (20 left), a loss of 12.5%, so R1 = 87.5%. They finish on 180 from 40 overs. Team B start a 40-over chase with R2 = 89.3%. Because R2 > R1, target = 180 + (89.3 − 87.5) × 245 ÷ 100 = 184.41 → 185 to win.
DLS rules by format: T20, ODI, T10 and The Hundred
| Format | Overs per side | Minimum for a result | G50 (Standard Edition) | Notes |
|---|---|---|---|---|
| T20 / T20I | 20 overs | 5 overs for Team 2 (10 in some ICC knockouts) | 245 men · 200 women | Starts at the 20-overs row (56.6%) |
| ODI | 50 overs | 20 overs for Team 2 | 245 men · 200 women/Associates | The original home of D/L |
| T10 | 10 overs | Set by the competition | Per competition | Starts at the 10-overs row (32.1%) |
| The Hundred | 100 balls | 25 balls each side | Per ECB | DLS is applied ball by ball |
| List A / club one-day | 40–50 overs | Set by the league | 245 first-class · league average below | Use Custom overs |
| Test / first-class | Unlimited | Not applicable | — | DLS is not used; a draw is possible |
Test and first-class cricket don’t use DLS: lost time simply reduces the overs available, and a draw is a valid result.

A short history of the DLS method
- 1992: In the World Cup semi-final, the old “most productive overs” rule left South Africa needing 22 runs from a single ball against England. The outcry led to a search for a fairer system.
- 1997: Statisticians Frank Duckworth and Tony Lewis’s method is first used in international cricket, in Zimbabwe v England at Harare on 1 January 1997.
- 2001: The ICC formally adopts Duckworth–Lewis as the standard method for rain-affected limited-overs internationals.
- 2004: The computer-based Professional Edition becomes standard in international cricket. The published Standard Edition table remains the fallback.
- 2014: Australian statistician Professor Steven Stern becomes custodian of the method, and it is renamed Duckworth–Lewis–Stern (DLS).
- 2018: An ICC update from 30 September 2018, based on 700 ODIs and 428 T20Is, confirms that a single DLS version works for every format.
Common DLS misconceptions
- “It’s just run rate.” No. Wickets matter just as much. Losing 10 overs with 9 wickets in hand costs far more than losing them when 8 down.
- “A shorter chase means a proportionally smaller target.” A 12-over chase of a 160 T20 score isn’t 96 (12/20). Team 2 keeps all 10 wickets for fewer overs, so the target is higher.
- “The target can never be higher than Team 1’s score.” It can. If Team 1’s innings was cut short unexpectedly, Team 2 can receive more resources, and the G50 adds runs.
- “Par means you win.” Exactly level with par is a tie. Team 2 must be above par.
- “Every DLS app gives the same target.” Internationals use the Professional Edition software, which can differ from the Standard Edition by a few runs, especially at high scores.
Duckworth Lewis FAQs
How is the DLS target calculated?
Work out each team’s resources (overs left combined with wickets in hand) from the DLS table. If Team 2 has fewer resources, target = Team 1’s score × R2 ÷ R1, rounded down, plus 1. If Team 2 has more, add (R2 − R1) × G50 ÷ 100 runs to Team 1’s score, round down and add 1.
What is a par score in DLS?
The par score is the score Team 2 would need at that exact point (overs bowled and wickets lost) to be level with Team 1 under DLS. If the match is abandoned, Team 2 wins if they are above par, loses if below, and it’s a tie if they are exactly on par.
How does DLS work in T20 matches?
T20 uses the same DLS table as ODIs. A full 20-over innings starts at 56.6% of a 50-over innings’ resources. Team 2 must face at least 5 overs (10 in some ICC knockout matches) for a result to stand.
What is the minimum number of overs for a DLS result in an ODI?
In men’s ODIs, a minimum of 20 overs must be bowled to the team batting second to constitute a match, unless a result has already been reached earlier.
What is G50 in the Duckworth Lewis method?
G50 is the average score expected from a team batting first in an uninterrupted 50-over match. The Standard Edition uses 245 for full-member nations, Under-19 internationals and first-class teams, and 200 for ICC Associates, women’s ODIs and Under-15 internationals.
Why is the DLS target higher than the overs ratio suggests?
Because Team 2 still has all 10 wickets for fewer overs, so they can bat more aggressively. Resources are not proportional to overs, so cutting a chase from 20 to 12 overs removes much less than 40% of Team 2’s resources.
Can the DLS target be higher than Team 1’s score plus one?
Yes. If Team 1’s innings was cut short without warning (for example, rain ended it at 40 overs when they planned for 50), Team 2 can receive more resources than Team 1, and runs are added to the target using G50.
Is DLS the same as Duckworth Lewis?
Essentially yes. Frank Duckworth and Tony Lewis created the D/L method in 1997. In 2014 Professor Steven Stern became its custodian and refined it, and it was renamed Duckworth–Lewis–Stern (DLS).
Is DLS used in Test cricket?
No. DLS is only used in limited-overs cricket (ODI, T20, T10, The Hundred and domestic one-day games). In Tests, lost time reduces the overs available, and a draw is a valid result.
How does DLS affect net run rate?
When a match is decided by DLS, Team 1 is credited with the par score (target minus one) from the overs Team 2 were allocated, and Team 2 with their actual runs and overs. If a side is bowled out, its full allocation of overs counts.
Why does this calculator sometimes differ from the official target?
International matches use the DLS Professional Edition, computer software run by match officials. This calculator uses the published Standard Edition, so targets can differ by a few runs, especially with high scores. The match referee’s figure is always the official one.
DLS method kya hai aur target kaise nikalte hain?
DLS (Duckworth–Lewis–Stern) baarish se ruke match mein naya target set karta hai. Yeh overs aur wickets dono ko milakar ‘resources’ nikalta hai. Agar Team 2 ke resources kam hain to target = Team 1 ka score × R2 ÷ R1, decimal hatao aur 1 jodo. Is calculator mein bas overs, wickets aur rain break daaliye; target aur par score turant mil jaayega.
