What is the Required Run Rate Calculator?
In a run chase, the required run rate (RRR or asking rate) tells you how many runs per over the batting side needs to win. The calculator takes the target, current score and overs bowled and shows runs needed, balls remaining and RRR.
Compare it with the current run rate from the Run Rate Calculator. If you only know the first-innings total, the Cricket Target Calculator sets the target first.
How to use the Required Run Rate Calculator
- Enter the target (first-innings score + 1).
- Enter the chasing team's current score.
- Enter overs bowled and the total overs (20 or 50).
- Read runs needed, balls left and RRR.
Formula
RRR = runs needed ÷ (balls left ÷ 6)
Example
Chasing 181 in a T20, a team on 102 after 12.0 overs needs 79 runs from 48 balls: RRR = 9.88.
Overs and balls: 4.3 is not 4.3
In cricket, 4.3 overs means 4 overs and 3 balls, which is 27 balls or 4.5 "real" overs, not 4.3. All our cricket calculators convert overs to balls correctly (overs × 6 + balls). Enter overs in the usual cricket way and the maths is handled for you.
Reading the chase
If RRR is close to the current run rate, the chase is on track. When RRR goes above 12 in T20s, teams usually need boundaries every over. Wickets in hand matter as much as the rate: 9.5 an over with 8 wickets left is very different from the same rate with 2 left.
