How this was worked out
- 1Usable playing time210 minutes less 30 of interval = 180
- 2Time available to this innings180 / 2 = 90 minutes, because both innings must fit
- 3Overs at the required rate90 / 60 x 14.28 = 21 overs
How the number is worked out
The formula
Overs bowlable = (usable minutes / 60) x required over rate- usable minutes
- Time left before the cut off, less any interval still to come.
- required over rate
- Overs per hour the playing conditions require. Commonly 14.28 in a 50 over match, which is 50 overs in three and a half hours.
In the first innings the remaining time has to cover both innings, so only half of it is available to the side batting.
A worked example: rain during the first innings
Play can restart with 210 minutes left before the cut off, and a 30 minute interval still to come.
The match is 50 overs a side with a 20 over minimum for a result.
- 1Usable playing time210 - 30 interval = 180 minutes
- 2Time for this innings180 / 2 = 90 minutes, because both innings must fit
- 3Overs at the required rate90 / 60 x 14.28 = 21 overs
- 4Compare with the minimum21 is above the 20 over minimum, so a result is possible
Twenty one overs a side, just clearing the minimum. One more delay of any length and the match goes.
Rules and edge cases
The situations that change the answer, and the ones most calculators get wrong.
The first innings only gets half the time
Both innings have to finish before the cut off, so time remaining during the first innings is shared. A common error at the ground is to allocate all the remaining time to the side batting, which produces an over count the match can never complete.
The interval comes out before anything else
Whatever interval is still to come is not playing time. Take it off the total before dividing, or the plan is short by exactly that amount.
The minimum for a result is a competition rule, not a universal one
Twenty overs a side is common in 50 over cricket and five in a Twenty20, but competitions vary and some use different minima for different rounds. Check the playing conditions rather than assuming the international standard.
Overs reduced does not automatically mean a revised target
This works out how many overs can be bowled. If the second innings is shorter than the first, the target itself has to be revised, and that is a DLS calculation rather than a time calculation.
Over rates in the field are usually slower than the requirement
The arithmetic assumes sides bowl at the required rate. In practice they often do not, so a plan that finishes exactly at the cut off tends to run over. Umpires usually build in a margin.
Frequently asked questions
Take the playing time remaining, subtract any interval still to come, divide by 60 and multiply by the required over rate. In the first innings, halve the time first because both innings have to fit.

The rain rules applied while the match is happening
Crickslab knows the format, the minimum overs and the over rate your competition runs under, and applies the revised target automatically once the overs are entered.
