What does this calculator mean?
When rain or bad light cuts overs from a limited-overs match, the target has to change so neither side gains an unfair advantage. The DLS par score calculator gives you a fast estimate of that revised target from three numbers: the original target, the overs lost and the wickets lost.
It works on the idea behind the Duckworth-Lewis-Stern method: a team's scoring potential depends on the overs and wickets it still has. Losing overs and wickets both reduce the resources available, so the target shrinks in proportion.

Formula used
Example
Inputs: Target 280, overs lost 10, wickets lost 3.
Resource %: 100 − (10 × 2.5 + 3 × 7.5) = 100 − 47.5 = 52.5%
Revised target: (280 × 52.5) ÷ 100 = 147 runs
Frequently asked questions
Is this the official DLS target?
No. The official Duckworth-Lewis-Stern calculation uses detailed resource tables and professional software. This calculator gives a quick linear estimate that is useful for fans, local matches and planning.
Why do wickets lost matter?
A side with more wickets in hand can bat more aggressively, so it has more scoring resources left. Each wicket lost therefore reduces the resources, and the target, more than a single over does.
