Run rate calculator
Enter the score and the overs bowled. You get the current run rate and the projected score, and in a chase the runs needed and the required run rate.

How it works
Run rate is runs scored per over: the runs divided by the overs faced. Overs count balls, not decimals: 10.2 overs is 10 overs and 2 balls, which is 10.333 overs, not 10.2. So 85 runs in 10.2 overs is 85 / 10.333 = 8.23 an over.
The required run rate is the runs still needed divided by the overs left. Chasing 171 at 85 after 10.2 overs of a T20, the side needs 86 more from 9.4 overs (58 balls): 86 / 9.667 = 8.90 an over.
The projected score is where the innings ends if the current rate carries on for every over: the runs so far, scaled up to the full overs. The calculator also shows the score at a few whole rates around it, the way TV graphics do, because the last overs usually go faster.
Wickets matter too. A side with many wickets in hand can bat faster at the end, so treat the projection as a guide. Once a side is all out, its innings is over and the projection is simply its score.
A worked example
Rangers chase 171 in a 20-over match and are 85 for 3 after 10.2 overs (62 balls).
Current run rate: 85 x 6 / 62 = 8.23 an over. Projected score at that rate: 85 x 120 / 62 = 164.5, so about 165.
Runs needed: 171 - 85 = 86 from 58 balls. Required run rate: 86 x 6 / 58 = 8.90 an over, so Rangers must speed up a little.

How do you calculate run rate in cricket?
Divide the runs by the overs faced, counting the balls of a part over as sixths: 85 runs in 10.2 overs is 85 / 10.333 = 8.23 runs an over.
What is the required run rate?
The runs the chasing side still needs divided by the overs it has left. It tells you how fast the side must score from now on to win.
How is the projected score worked out?
The current run rate is carried on to the end of the innings: runs so far x total balls / balls faced. The calculator also shows the score at a few other rates for the overs left.
How do I enter overs like 10.2?
Type them as the scoreboard shows them: 10.2 means 10 overs and 2 balls. The balls part goes up to 5 with six-ball overs (or 7 with eight-ball overs).
Does it work for 8-ball overs and short matches?
Yes. Pick the balls an over (6, 8, 5 or 4) and any number of overs from 1 to 100. The rates are in runs per over of that length.
