What this calculator does
Net run rate, or NRR, is the figure cricket tournaments use to separate teams that finish level on points: it is the team’s run rate while batting minus its run rate while bowling, calculated as NRR = (runs scored ÷ overs faced) − (runs conceded ÷ overs bowled). A positive NRR means a team has, on average, scored faster than it has conceded; a negative one means the opposite.
This nrr calculator takes the runs and overs from both innings of a match and works out the net run rate using that standard method, including the overs-notation quirk (48.4 overs means 48 overs and 4 balls, not 48.4 decimal overs) and the rule that a team all out before using its full quota of overs is credited with having faced or bowled the full innings length, not just the overs actually completed.
The formula
Overs faced and overs bowled are each converted from the X.Y cricket notation, where Y is a ball count from 0 to 5, into a decimal number of overs (X + Y ÷ 6). Runs scored divided by the decimal overs faced gives the batting run rate; runs conceded divided by the decimal overs bowled gives the bowling run rate. Net run rate is the batting rate minus the bowling rate.
| Term | Meaning |
|---|---|
| Run rate | Runs scored per over, either while batting (for) or while bowling (against). |
| Overs faced / bowled | The number of overs actually used, in cricket’s X.Y notation, where Y counts balls (0–5), not tenths of an over. |
| All out | When a team loses all its wickets before using its full quota of overs; by convention, its overs faced (or bowled, for the opposition) are then counted as the full innings length rather than the overs it actually got through. |
| Innings length (quota) | The number of overs allotted to each innings in the match, such as 50 in a One Day International. |
The inputs explained
| Field | What to enter |
|---|---|
| Runs scored | Total runs scored by the team whose NRR is being calculated. |
| Overs faced (e.g. 48.4 = 48 overs, 4 balls) | Overs actually faced while batting, in X.Y notation (for example 48.4 for 48 overs and 4 balls). Ignored if the team was all out. |
| Batting team all out? | Whether the batting team lost all ten wickets before using its full quota of overs. |
| Runs conceded | Total runs conceded while bowling. |
| Overs bowled (e.g. 50.0) | Overs actually bowled, in X.Y notation. Ignored if the opposition was all out. |
| Opposition all out? | Whether the opposition lost all ten wickets before using its full quota of overs. |
| Innings length (match overs) | The full innings length for the match, such as 50 overs for an ODI or 20 for a T20. |
When to use it
Ranking teams level on points in a group stage
When two or more teams finish a tournament stage with the same number of points, net run rate is the standard tiebreaker, so working it out for each completed match tracks a team’s standing through the tournament.
Working out the effect of a bowled-out innings
A team that is bowled out cheaply still counts as having used its full quota of overs for run rate purposes, not just the overs it actually faced, which materially changes the calculation compared with treating the overs faced at face value.
Converting cricket overs notation correctly
Reading 48.4 overs as 48.4 decimal overs rather than 48 and 4 balls (48.667 decimal overs) is a common source of run rate errors; entering the overs as printed in the scorecard avoids that mistake.

How NRR changes with the batting all-out rule
The same 35.2 overs actually faced, once counted at face value and once counted as an all-out innings using the full 50-over quota.
| Batting team all out? | Net run rate |
|---|---|
| No (uses 35.2 overs faced) | +0.694 |
| Yes (uses 50-over quota) | -0.800 |
How NRR responds to the batting total, other figures held fixed
Runs scored increasing while overs faced, runs conceded and overs bowled all stay the same.
Questions
What is the NRR formula?
NRR = (runs scored ÷ overs faced) − (runs conceded ÷ overs bowled), using decimal overs rather than the raw X.Y scorecard notation.
How do I convert overs like 48.4 into decimal overs?
The number after the point in cricket’s overs notation is a ball count, from 0 to 5, not tenths of an over. So 48.4 overs is 48 overs plus 4 balls, which equals 48 + 4÷6 ≈ 48.667 decimal overs. This calculator does that conversion for you.
What happens to NRR if a team is bowled out?
If a team loses all ten wickets before using its full quota of overs, it is credited with having faced (or, for the bowling side, bowled) the full innings length for run rate purposes, not just the overs it actually completed. This generally lowers a bowled-out team’s NRR compared with using the overs actually faced.
Can NRR be negative?
Yes. A negative NRR simply means a team has, across its games, conceded runs faster than it has scored them, and it ranks below a team with a higher (or positive) NRR when teams are level on points.
