Required Run Rate Calculator
Find out exactly what the chasing side needs. Enter the target, the current score and how much of the innings has gone, and Criko returns the required run rate along with the balls left.
Formula
Runs Required = Target - Current ScoreBalls Remaining = (Total Match Overs x 6) - Legal Balls BowledRequired Run Rate = Runs Required / (Balls Remaining / 6)
Example
- Target 200, current score 100, 20 overs in total, 10 overs completed.
- Runs required = 200 – 100 = 100.
- Balls remaining = 120 – 60 = 60, which is 10 overs.
- Required run rate = 100 / 10 = 10.00 runs per over.
Frequently asked questions
Is the target the same as the opposition score?
No. The target is one run more than the score the team batting first made. Chasing 199 means the target is 200.
What happens if the overs are reduced by rain?
Enter the revised number of overs in the total match overs field. If the target itself was revised under the Duckworth-Lewis-Stern method, enter the revised target.
What is the required run rate?
The required run rate, often called the asking rate, is the number of runs per over the chasing side needs from the balls that remain to reach its target. It changes after every ball: a boundary brings it down and a dot ball pushes it up. Comparing it with the current run rate shows at a glance whether a chase is ahead or behind.
How to use the required run rate calculator
- Enter the target, which is the first-innings score plus one.
- Enter the chasing side’s current score.
- Enter the length of the innings in overs, for example 20 or 50.
- Enter the overs and balls already bowled. The result shows the runs required, balls remaining and the rate needed per over.
Worked examples
Chasing in a T20
Target 181. The chasing side is 112 after 14.2 overs, so 86 balls have gone and 34 remain. They need 69 from 34 balls: 69 ÷ (34 ÷ 6) = 12.18 runs per over.
An ODI chase
Target 290 and the score is 150 after 30 of 50 overs. That is 140 needed from 120 balls, or 7.00 runs per over.
The final over
14 needed from the last 4 balls is 14 ÷ (4 ÷ 6) = 21.00 runs per over, or 3.5 runs a ball.
Common mistakes
- Using the opposition’s score as the target. The chasing side needs one more run than that to win; equal scores is a tie.
- Subtracting overs as decimals: 20 − 14.2 is not 5.8. It is 34 balls, which is 5.4 overs, or 5.67 overs in the maths.
- Ignoring a revised target. In a shortened match, use the target and overs set by the officials.
