How the Required Run Rate Calculator (Cricket Chase) works
Runs needed are the target minus the current score. Balls left are the total balls in the innings minus the balls already bowled.
The required rate is runs needed divided by overs left. Compare it with the current rate: if the required rate is much higher, the batting side must accelerate, which is harder with fewer wickets in hand.
The formula
Worked example
Using the default values shown in the calculator:
| Target to win | 287 |
|---|---|
| Current score | 150 |
| Overs completed | 30 |
| Extra balls | 0 |
| Total overs in the innings | 50 overs (ODI) |
| Wickets lost | 3 |
- Runs needed: 287 − 150 = 137. Balls left: 300 − 180 = 120 (20 overs).
- Required rate = 137 ÷ 20 = 6.85 per over, against a current rate of 5.00.
Result:
| Required run rate | 6.85 |
|---|---|
| Runs needed | 137 |
| Balls left | 120 |
| Current run rate | 5.00 |
| Runs needed per ball | 1.14 |
| Wickets in hand | 7 |
Frequently asked questions
Is the target one more than the other team's score?
Yes. To win, the chasing team must pass the first team’s total, so the target is their score plus one.
What about rain-reduced matches?
Rain-affected targets are set by the Duckworth-Lewis-Stern method, which uses published resource tables. Enter the revised target and overs here once the officials announce them.
