Required Run Rate Calculator

Use this during a chase. Enter the target (the first-innings total plus one, or a revised DLS target), the chasing side's current score, the overs bowled so far and the overs available, and the calculator shows what is needed from the balls that remain.

The calculator runs in your browser and needs JavaScript.

Reading the result

Runs needed is the target minus the current score. Balls left is the innings length minus the balls already bowled, counting 15.4 overs as 15 overs and 4 balls. The required run rate is runs needed divided by the overs left, and the current run rate is the score divided by the overs bowled. When the required rate is well above the current rate, the chasing side has to accelerate; when it is below, the side can afford to protect wickets.

Run rates hide how many wickets are left, which matters as much as the rate itself. Needing 10 an over with eight wickets in hand is a very different chase from needing 10 an over with two. Our guide to run rate and required run rate goes through how to read a chase.

Targets in shortened matches

If rain has reduced the overs, use the revised target and the revised number of overs that the umpires announce. Those come from the DLS method, which this calculator does not compute; the DLS guide explains how they are set.
