How this calculator works
Net run rate is the difference between a team's run rate with the bat and its run rate with the ball. It is used to break ties in league tables when teams finish on the same points. Balls are converted to a decimal fraction of an over by dividing by six, so 47.3 overs is 47.5 overs in decimal terms. The rule that catches people out is the all-out case: if a team is bowled out before its overs are complete, the full allocation counts as the overs faced. Enter the full quota in that case, otherwise the rate is artificially high. A chase that is completed early counts the overs actually used.
Formula
Net run rate = runs scored / overs faced - runs conceded / overs bowled. Overs in scorecard notation x.y become x + y/6 decimal overs. Solving for runs: runs scored = (NRR + runs conceded / overs bowled) x overs faced; runs conceded = (runs scored / overs faced - NRR) x overs bowled.
Worked example
A team scores 250 in 50 overs and concedes 220 in 50 overs. Its rates are 5.00 and 4.40, so NRR = +0.600. Scoring 300 in 48.2 overs (48.333 decimal overs) gives 6.207 an over; conceding 280 in 50 gives 5.600, for NRR = +0.607.

Frequently asked questions
What do I enter when a team is all out?
Enter the full quota of overs for the innings, not the overs actually bowled. The competition rule counts the full allocation so that a team cannot improve its net run rate by being bowled out quickly.
Why is 48.2 overs not 48.2 decimal overs?
Cricket notation uses the digit after the point for balls. Two balls is one third of an over, so 48.2 overs is 48 + 2/6 = 48.333 decimal overs.
Does a no-result match count?
Competition rules vary. Many tournaments exclude abandoned matches from the net run rate calculation, while others treat them as zero. Follow the playing conditions for the competition.
