How to use
- 1Set the overs per innings (20 for T20, 50 for ODIs).
- 2For a chase, enter runs, overs faced and the target to get the required run rate.
- 3In the NRR table, enter runs scored/conceded and overs faced/bowled for each match.
- 4Tick “all out” where a side was bowled out – its innings counts as the full quota of overs.
The net run rate formula and the all-out rule
NRR = (total runs scored ÷ total overs faced) − (total runs conceded ÷ total overs bowled) across the tournament. Under ICC playing conditions (T20 World Cup and Champions Trophy, current in 2026), a team that is bowled out is charged its full quota of overs, not the overs it actually lasted. In the example table three T20 matches give 521 runs off 60 overs (8.683) and 401 runs conceded off 59.1 overs (6.777): NRR +1.906. Super Overs and no-result matches are excluded.
Overs notation: 19.4 is not 19.4
An over has six balls, so 19.4 means 19 overs and 4 balls – 19⅔ or 19.667 overs. Treating it as the decimal 19.4 gives the wrong run rate. The calculator converts every entry to balls (19.4 = 118 balls), does the maths in balls and writes the result back in overs notation. Only 0–5 is allowed after the dot.
Required run rate and limitations
Required run rate = runs still needed ÷ overs remaining. A T20 side on 112 after 13.4 overs chasing 181 needs 69 off 38 balls – 10.89 an over – against a current rate of 8.20. Rain-reduced matches decided by DLS use special adjustments (the side batting first is credited with the par score); the tool does not apply them and assumes the same quota for every match, so enter adjusted figures yourself for those games.
Frequently asked questions
How is net run rate calculated?
Divide total runs scored by total overs faced, then subtract total runs conceded divided by total overs bowled. A side that is all out is charged the full quota of overs.
Why does an all-out team count the full 20 overs?
It is an ICC playing condition: otherwise a side bowled out early could keep a high run rate. A team all out for 120 in 15 overs is treated as 120 off 20.
How do you calculate the required run rate?
Divide the runs still needed by the overs left. Needing 50 off 30 balls means 50 ÷ 5 = 10 runs an over.
How many overs is 19.4?
19 overs and 4 balls – 19⅔ ≈ 19.667 overs, or 118 balls.
