NRR Calculator (Net Run Rate)
A team that scores 287 runs in 50 overs and concedes 243 in 50 overs has a net run rate of +0.880. This NRR calculator works out cricket net run rate exactly as the ICC does, including partial overs, where 47.3 overs means 47 overs and 3 balls, not 47.3 in decimal. Enter runs and overs for both sides of the innings and get the NRR to three decimals.
Quick answer
Net run rate is your scoring rate minus the rate you concede. NRR = (runs scored / overs faced) minus (runs conceded / overs bowled).
Net run rate
+0.880
Run rate for
5.74
Run rate against
4.86
What this tells you
- •Net run rate is your scoring rate minus the rate you concede. NRR = (runs scored / overs faced) minus (runs conceded / overs bowled).
- •Partial overs count by balls. 47.3 overs in cricket notation is 47 + 3/6 = 47.5 decimal overs.
- •A positive NRR means you score faster than you concede. Tournament tables use it to split teams level on points.
- •If a team is bowled out early, tournament rules charge them their full quota of overs, not the overs actually faced.
How to Use
- 1Enter the runs your team scored, then the overs and balls faced.
- 2Enter the runs conceded, then the overs and balls bowled.
- 3Balls are the extra deliveries past whole overs, from 0 to 5.
- 4Read the NRR, plus each side's raw run rate below it.
How It Works
Formula
NRR = (runs scored / overs faced) - (runs conceded / overs bowled)Convert overs to decimal first by dividing the extra balls by 6. A team scoring 287 in 50 overs has a run rate of 5.74. If they conceded 243 in 50 overs, the rate against is 4.86. Subtracting gives an NRR of +0.88. Over a tournament, use total runs and total overs across all matches, not the average of per-match NRRs.
Calculation note: values are processed in the order shown above, using the current input units.
Worked Examples
Full 50-over match
Run rate for is 5.74, rate against is 4.86, difference +0.88.
Chasing side wins early
42.3 overs is 42.5 decimal. 245 / 42.5 = 5.765 against a concede rate of 4.88.
T20 match
19.4 overs is 19.667 decimal. The concede rate of 9.66 beats the scoring rate of 9.25, so NRR is negative.
Balls to Decimal Overs
How cricket overs notation converts to decimal overs for the NRR formula.
| Notation | Decimal overs |
|---|---|
| 20.1 | 20.167 |
| 20.2 | 20.333 |
| 20.3 | 20.5 |
| 20.4 | 20.667 |
| 20.5 | 20.833 |
| 21.0 | 21.0 |
Common mistakes
- Treating 47.3 overs as 47.3 decimal. The .3 means 3 balls, which is 0.5 of an over, so the correct decimal is 47.5.
- Averaging per-match NRRs across a tournament. The correct method divides total runs by total overs across all matches.
- Forgetting the bowled-out rule. A team dismissed in 35 overs of a 50-over match is charged all 50 overs when tournament NRR is calculated.
