The rule
The target is the number you reach, not the one you pass
Chasing 181 means scoring 181. Matching the first innings total ties the match; the published target is already one more than the score batted first. So the runs still needed are the target minus what is on the board, and this calculator takes the target rather than asking you to add one yourself.
Balls remaining decide everything else. Twelve overs gone in a twenty-over innings leaves forty-eight balls, and eighty-one runs from forty-eight balls is 10.13 an over. Enter 12.3 and it leaves forty-five, because the part over is three balls and not three tenths.
When the runs needed exceed six times the balls left, the tool says so. That is a bound rather than a prediction: six off every remaining ball is the most that can be scored without extras, so anything above it cannot be done. It says nothing about whether a gettable chase will be got.

Questions
How is required run rate calculated?
Runs still needed divided by the overs still available. Runs needed is the target minus the current score, and the overs available come from the balls left, so a part over counts as balls: 12.3 bowled in a twenty-over innings leaves forty-five balls, which is seven and a half overs, not seven and seven tenths.
What is the difference between run rate and required run rate?
Current run rate is what the chasing side has managed so far: runs scored divided by overs faced. Required run rate is what they still need from here. Both are shown together because the gap between them is the actual state of the chase, and a side can have a healthy current rate while the required one climbs away from it.
Does this account for DLS or rain?
No. This is the straightforward arithmetic of an uninterrupted chase. Duckworth-Lewis-Stern revises a target using a published resource table and is not something to approximate, so if your match has been shortened you want the official DLS figure rather than this. Enter the revised target here once you have it and the rest of the sum holds.
