How to calculate run rate and required run rate
Short answer: current run rate = runs ÷ overs bowled. Required run rate = runs needed ÷ overs left. Always convert overs to balls first: 12.4 overs is 76 balls, not 12.4.
1. Current run rate (CRR)
CRR = runs × balls per over ÷ legal balls bowled. Example: 84 runs after 12.4 overs → 84 × 6 ÷ 76 = 6.63 runs per over.
2. Required run rate (RRR)
Target = first-innings total + 1. RRR = (target − runs) × balls per over ÷ balls left. Example: chasing 151 in 20 overs, 84 after 12.4 overs → need 67 off 44 balls → 67 × 6 ÷ 44 = 9.14.
3. Converting overs
Overs are written as completed overs and balls: 7.3 means 7 overs and 3 balls (45 balls). Convert to decimal overs only by dividing balls by the balls per over.
4. Short or long overs
Tape-ball and street games sometimes use 4, 5 or 8 balls per over. Use that number instead of 6 in every formula: with 5-ball overs, 10.2 overs = 52 balls.
How Wickora helps
Wickora shows the current run rate under the score in every innings, and in the chase the target, runs needed, balls left and required run rate — using the balls per over you set for the match.
FAQ
Why is 12.4 overs not 12.4 in the formula?
Because .4 means 4 balls, not 0.4 of an over. 12.4 overs = 12 × 6 + 4 = 76 balls = 12.67 overs.
What is a good required run rate to chase?
It depends on the format and the pitch. In short local games, a required rate well above the current rate with few wickets left is hard.
Does Wickora show the required run rate?
Yes. In the second innings it shows the target, runs needed, balls left and the required run rate under the score.
