How Is Net Run Rate Calculated in Cricket?

The basic NRR formula

Net Run Rate equals average runs scored per over minus average runs conceded per over. For a single completed match, divide each total by the relevant overs and subtract the opposition rate from your team's rate.

Example: Team A scores 180 in 20 overs, a run rate of 9.00. Team B scores 150 in 20 overs, a run rate of 7.50. Team A's match NRR is +1.500 and Team B's is -1.500.

Cricket overs are not decimals

19.4 overs means 19 complete overs and four balls. In a six-ball over, that is 118 balls, or 19.6667 decimal overs for the division. Entering 19.4 as a normal decimal gives the wrong answer.

NRR across a tournament

Competition NRR is normally based on aggregate runs and aggregate overs across the relevant matches, not the simple average of each match's NRR. This means a large win or defeat can continue to affect the table.

All-out innings and revised matches

Official playing conditions commonly treat a team dismissed before its full quota as having faced the full entitled quota for NRR purposes. No-results, shortened games and DLS-adjusted targets can introduce competition-specific rules, so official tournament conditions take priority.

Why NRR scenarios become complicated

To calculate the winning margin needed to overtake another team, you must know both teams' aggregate runs and overs, not only the current displayed NRR. The required target also changes depending on which side bats first.

Frequently Asked Questions

Is 19.4 overs the same as 19.4 decimal overs?

No. It means 19 overs and four balls. With six-ball overs, that equals 19.6667 overs for rate calculations.

Is tournament NRR an average of match NRR values?

Usually no. It is calculated from aggregate runs and overs across the included matches.

What happens if a team is bowled out early?

Official competition rules commonly use the full entitled quota rather than the actual overs faced, but you should check the specific playing conditions.
