Run rate & chase calculator

A worked chase: 181 from 20 overs

At 96 after 12.4 overs, 76 legal balls have been used: 12 × 6 + 4. There are 44 balls remaining, and 85 runs are needed. The required rate is 85 × 6 ÷ 44 = 11.59 runs per over. The current rate is 96 × 6 ÷ 76 = 7.58. These figures describe the arithmetic, not the chance of winning.

Why 12.4 is not a decimal

In cricket notation the digit after the dot counts legal balls in the unfinished over. It can be 0 through 5. Entering 12.6 is rejected: write 13.0 instead. Treating 12.4 as a decimal undercounts the deliveries and changes both rates.

Target means the winning total

If the first innings ended at 180, the normal target is 181. Entering 180 would calculate the runs required to tie. A revised target must come from the official score, and the new innings quota must also be entered. This calculator does not compute DLS targets.

Use it as a comparison

Try changing the current score from 96 to 106 while keeping the same ball count. The required rate falls to 10.23. Ten runs of progress changed the equation; the remaining batters, pitch and bowling options have not been measured. Do not turn this arithmetic into a win probability.
