Current run rate is team runs divided by overs actually completed, expressed as a decimal duration. During an unfinished over, convert the recorded overs to valid balls first. A hypothetical score of 101 after 14.3 overs has a run rate of 6.97, not 7.06.
Work through the unfinished over
- Convert 14.3 overs into valid balls: 14 × 6 + 3 = 87.
- Use the team total, 101, including extras.
- Calculate runs per six valid balls: 101 × 6 / 87 = 6.9655...
- Round only the displayed result: 6.97 runs per over.
Dividing 101 by the decimal number 14.3 produces about 7.06. That denominator represents a different duration. The correct decimal duration for 87 valid balls is 14.5 overs.
Why dot balls lower the rate
Suppose the same hypothetical innings adds three valid dot balls. The total stays 101, but 15 overs, or 90 valid balls, have now been used. The new rate is 101 × 6 / 90 = 6.73 after rounding.
| Team total | Overs | Valid balls | Current rate |
|---|---|---|---|
| 101 | 14.3 | 87 | 6.97 |
| 101 | 15.0 | 90 | 6.73 |
No runs were removed. The innings total is spread across a larger denominator. Conversely, an extra can increase the numerator without advancing the valid-ball count.
Record the inputs, not just the displayed rate
For a reproducible calculation, note the innings, team total and recorded overs at the same moment. Keep full precision until the final rounding step. Do not combine an earlier total with a later ball count, or average the rounded rates from several snapshots.
Current rate is not a forecast
This measure describes scoring up to the recorded point. It does not account for wickets available, conditions or future deliveries, and is not a probability of winning. Required run rate is a different calculation based on runs still needed and balls remaining.
What if no valid ball has been recorded? The denominator is zero, so no finite current rate can be calculated, even if extras have already added runs. Leave it unavailable until the denominator is positive. Browse the cricket articles.
