Duckworth-Lewis Calculator
The Duckworth Lewis method DLS calculator helps across major cricket formats i.e. 50 Overs, Twenty20 (T20) matches, PSL, and (IPL) Indian Premier League.
It considers two critical resources in limited-overs cricket: available overs and wickets remaining.
Duckworth-Lewis DLS For Cricket Formula
Resource Percentage = f(remaining overs, wickets in hand)The formula explained:
- Target Score = (Team 1’s score) × (Team 2’s resources/Team 1’s resources)
- Resource tables considering 100% resources as 50 overs with 10 wickets
If Team A scores 280/4 in 50 overs, and rain reduces Team B’s innings to 40 overs, the DLS method might set a revised target of 250, accounting for the 20% reduction in available overs while considering wickets in hand.
Full Match to Reduced Chase: Team A scores 300/6 in 50 overs Rain reduces Team B’s innings to 40 overs Available resources: 90.1% Revised target = 300 × 0.901 = 270 runs
Mid-Innings Interruption: Team A: 250/5 in 45 overs when rain stops play Resumption allows only 40 overs Original resources: 95% Remaining resources: 85% Projected score = 250 × (100/95) = 263
Multiple Interruptions: Team A: 280/4 in 50 overs Team B: 140/2 in 25 overs when rain hits Game resumes with 35 overs Resources lost: 15% Par score at interruption: 155 New target: 240 in 35 overs
How to Calculate DLS in Cricket?
- Resource Assessment: Determine available resources based on overs and wickets
- Target Adjustment: Apply resource percentage to original target
- Par Score Calculation: Calculate required runs at each stage
In a match where Team A scores 320/6 in 50 overs, and Team B faces a reduction to 30 overs with 9 wickets in hand:
- Available resources = 68.5%
- Revised target = 320 × 0.685 = 219 runs
What is the Duckworth-Lewis Score?
The DLS score represents the par score that the chasing team needs to achieve at any point during their inning considering:
- Current match situation
- Resources consumed
- Resources remaining
The DLS par score is dynamic and changes with:
- Overs completed
- Wickets lost
- Match situation
