Required run rate is the number every chase is measured against: the pace the batting side must keep up to win from where it stands. This free required run rate calculator works for any T20, IPL or ODI chase. Enter the target and the current score to get the RRR, the current run rate, the runs needed, the projected finish, and a clear ahead-or-behind readout.
Quick Answer: The Required Run Rate Formula
Required run rate (RRR) = runs still needed / overs remaining. So 60 needed off 8 overs is an RRR of 7.50 an over. Compare it with the current run rate (runs scored / overs faced): if the current rate is higher, the side is ahead of the asking rate; if it is lower, the rate is climbing and the chase is slipping.

How required run rate is calculated
Required run rate answers one question: from this exact point, how fast must the chasing side score to win? You take the runs it still needs (the target minus the current score) and divide by the overs remaining. Multiply out and you have a runs-per-over figure. Because it only looks forward, the RRR moves every ball – a dot raises it slightly, a boundary brings it down.
It pairs with the current run rate, which looks backward: runs scored divided by overs faced. Reading the two together is how commentators call a chase. If the current run rate is higher than the required run rate, the batting side is ahead of the asking rate and the equation is shrinking. If it is lower, the required rate is rising and the pressure is building. The projected score in the tool above makes this concrete by extending the current rate to the end of the innings.
Worked example
A side is chasing 191 to win. After 12 overs it is 100 for 3.
- Runs needed: 191 – 100 = 91
- Overs remaining: 20 – 12 = 8 (48 balls)
- Required run rate: 91 / 8 = 11.38 an over (1.90 a ball)
- Current run rate: 100 / 12 = 8.33 an over
The current rate (8.33) is well below the required rate (11.38), so this side is behind the asking rate. At its current pace it would finish around 167, roughly 24 short. To get back on terms it needs to lift to about 11 an over straight away – which in practice means finding boundaries rather than rotating strike, and spending the wickets in hand to do it.
Reading a chase: ahead, behind, and the par trap
The required run rate is a guide, not a verdict, and the reason is wickets. A side needing 10 an over with all ten wickets in hand is in a far stronger position than one needing 8 an over with one wicket left, even though the second rate is lower. That is why the tool shows wickets as context: the rate tells you the pace, the wickets tell you whether that pace is realistic.
It is also why required run rate is not the same as a rain-rule par score. RRR assumes even, wicket-blind scoring. The official DLS par score factors in wickets lost and the resources a side has left, which is why a team can be ahead on required run rate yet behind the DLS par line. Treat the RRR as your live feel for the chase, and remember the umpires settle rain-affected games with DLS, not with this number.
The single most useful habit in watching a chase is to stop staring at the required run rate alone and pair it with wickets and the next over. A required rate of nine looks the same on the scoreboard whether a side is two down or seven down, but those are completely different games. The rate sets the task; the wickets decide whether it is a formality or a gamble.
The other thing the calculator makes obvious is how quickly a quiet over costs you. Six dots when you needed nine does not just leave three runs behind – it pushes that shortfall onto fewer remaining balls, so the rate jumps more than people expect. If you want the season-long version of the same idea, the same logic drives the net run rate that decides playoff seeding.
Required Run Rate Calculator FAQs
What is required run rate (RRR) and how is it calculated?
Required run rate is the runs still needed divided by the overs remaining, quoted per over. For example, 60 runs needed off 8 overs is an RRR of 7.50. It tells the chasing side the pace it must keep up from the current point to win.
What is the difference between current run rate and required run rate?
Current run rate (CRR) is runs scored divided by overs faced – how fast the side has gone so far. Required run rate (RRR) is runs needed divided by overs left – how fast it must go from here. If the current run rate is above the required run rate, the side is ahead of the asking rate.
How do I use this required run rate calculator?
Enter the target to win (the opposition total plus one), the current score, the overs completed and the total overs in the innings. The tool returns the required run rate, current run rate, runs needed, balls remaining, the projected score at the current pace, and whether the side is ahead or behind.
What is a chaseable required run rate in T20?
In T20, roughly six an over is par. Up to about nine is gettable with wickets in hand, nine to twelve is a tough ask, and above twelve needs boundaries almost every ball. Wickets lost matters as much as the rate itself.
How is required run rate different from the DLS par score?
Required run rate is a simple pace figure that assumes even scoring. The DLS par score is the official rain-rule method that also factors in wickets lost. Use the required run rate as a live guide; umpires use DLS to settle rain-affected results.
Does this calculator work for ODIs and reduced-overs games?
Yes. Set the total overs to 50 for an ODI, or to any number for a rain-reduced game, and the maths works the same. The default is 20 overs for T20 and the IPL.
Bottom line
Required run rate is the clearest live read on a chase, as long as you pair it with wickets in hand. Use the calculator above to get the exact rate, the projected finish and the ahead-or-behind call for any T20, IPL or ODI run chase, then switch to the season picture with our IPL NRR calculator and the live IPL points table.
