Run Rate Calculator
The run rate of an innings is runs divided by overs. A side on 142 after 30 overs is scoring at 4.73 an over. On a scoreboard it appears as CRR, the current run rate.
- Balls faced
- 180
Run rate = runs scored ÷ overs faced
As with every rate in cricket, the overs have to be converted before dividing. Thirty overs and four balls is 184 balls, which is 30.67 decimal overs — not 30.4.
Run rate, current run rate and required run rate
Run rate describes what has happened: the runs on the board against the overs used. Required run rate describes what still has to happen: the runs still needed against the overs still left. A chase is usually read as the gap between the two.
When the required rate climbs above the current rate and keeps climbing, the chase is drifting. The moment they cross back is the moment a game turns.
Every run counts, whoever made it
A team run rate includes byes, leg byes, wides, no-balls and penalty runs, because all of them are runs on the board. This is different from a bowler's economy rate, which excludes byes and leg byes.
So the sum of the bowlers' runs conceded will not generally equal the team total. The difference is the extras that nobody is charged with.
Where run rate stops being useful
It treats every over as equal, and they are not. A side on 60 for 0 after ten powerplay overs is in a stronger position than one on 60 for 5, and the run rate is identical. Wickets in hand are what convert a rate into a total.
This is exactly the gap the Duckworth-Lewis-Stern method was built to close: it values overs and wickets together, as combined resource, rather than counting overs alone.
