Duckworth-Lewis Calculator
After a decade of match analysis, the most consistent way to set a fair rain-affected target is to track resources, not just run rate. This calculator applies the Standard Duckworth-Lewis-Stern method to produce a clean target and match result.

What problem does DLS solve?
In limited-overs cricket, both teams plan around 50 overs and 10 wickets. When rain removes overs, the chasing side faces a different risk-reward equation. DLS corrects for that by estimating the true scoring resources available.
The method treats overs and wickets as a combined resource pool. Fewer overs push teams to score faster, while fewer wickets reduce scoring potential. DLS balances both so the target stays fair.
DLS formulas
When Team 2 has fewer resources:
Par score = Team 1 score x (R2 / R1)
When Team 2 has more resources:
Par score = Team 1 score + G50 x (R2 - R1) / 100
R1 and R2 are the resource percentages from the Standard DLS table. The target to win is the par score rounded down, plus one run.
How to use the calculator
- Select the interruption type that matches the match situation.
- Enter Team 1 overs available and runs scored.
- Provide Team 2 overs, wickets, and interruption details as needed.
- Optional: add Team 2 runs to determine win, loss, or draw.
Example calculations
Practical match scenarios that show how DLS resources and targets are computed.
Example 1 — Team 2 innings delayed
Team 1: 231 runs from 30 overs. Team 2: 28 overs available.
R1 (30 overs, 0 wkts) = 75.1%
R2 (28 overs, 0 wkts) = 71.8%
Par = 231 x (71.8 / 75.1) = 220.85
Target to win = 221 runs
Example 2 — Team 2 innings cut short
Team 1: 268 from 50. Team 2: 229 from 45 overs, 6 wkts down.
Overs remaining = 5, remaining resources = 14.3%
R2 used = 100 - 14.3 = 85.7%
Par = 268 x (85.7 / 100) = 229.68
Target to win = 230 runs (229 is a draw)
Example 3 — Team 2 innings interrupted
Team 1: 273 from 50. Team 2: stop at 19 overs, 2 wkts; resume with 17 overs left.
Resources at stop: 31 overs left, 2 wkts = 68.6%
Resources at restart: 17 overs left, 2 wkts = 46.7%
R2 = 100 - 68.6 + 46.7 = 78.1%
Par = 273 x (78.1 / 100) = 213.21, target = 214
Example 4 — Team 1 innings interrupted
Team 1: stop with 16 overs left, 2 wkts; resume with 8 overs left. Team 2 gets 42 overs.
Team 1 resources: 100 - 44.7 + 25.5 = 80.8%
Team 2 resources: 42 overs, 0 wkts = 91.7%
Par = 170 + 245 x (91.7 - 80.8) / 100 = 196.71
Target to win = 197 runs

Frequently Asked Questions
- What does the DLS method solve?
- The Duckworth-Lewis-Stern method creates fair targets when rain or delays reduce overs. It balances two resources: overs remaining and wickets in hand.
- Why is it better than a straight run-rate reduction?
- Teams change intent when overs are cut, scoring faster but risking wickets. DLS models that behavior through resource percentages rather than a linear run-rate cut.
- What is G50 and when does it matter?
- G50 is the average score for a team batting first in a 50-over innings. It is used only when Team 2 has more resources than Team 1, increasing the target accordingly.
- Is this the Standard or Professional DLS edition?
- This calculator uses the Standard DLS resource table. The Professional edition is proprietary and not publicly available.
