How Is Net Run Rate Calculated? Follow
Net Run Rate is calculated as (runs scored/overs faced) - (runs conceded/overs bowled). This calculation excludes no result games (abandoned/cancelled) and those games where the total overs have not been entered into the summary score.
It does not take account of the situation where a side is bowled out inside its scheduled overs, where the calculation should use that figure rather than the actual overs; if you wish to correct it for that, then you should enter the scheduled overs for the innings in the summary result yourself instead of the actual overs bowled.
