About Duckworth Lewis Target Calculator

Under the Duckworth-Lewis-Stern method the par score scales team 1's total by the ratio of resources available to the two sides, and the winning target is one run above par. Resources combine overs and wickets remaining, which is why losing early wickets costs a chasing side more than losing overs at the same stage.

Formulas

Par score

par = team 1 score x team 2 resources / team 1 resources when team 2 has fewer resources

Target

target = floor(par) + 1
