Run Rate & Required Rate Calculator
Work out current run rate and the required run rate to chase a target — the two numbers that drive every limited-overs cricket run chase.
How it works
CRR = runs ÷ overs · RRR = (target − runs) ÷ (total overs − overs bowled)
Current run rate is runs scored per over so far; required run rate is the pace the chasing side must now maintain to reach the target in the balls remaining. When the required rate climbs above the current rate, the chase is falling behind and the batting side must accelerate; when it drops below, they are ahead of the game. Note that overs use cricket notation where 20.3 means 20 overs and 3 balls — enter partial overs carefully, as six balls make one over.
Worked example
Chasing 280, a team is 120 for 2 after 20 overs. CRR = 120 ÷ 20 = 6.00. They need 160 more from 30 overs, so RRR = 160 ÷ 30 = 5.33 — comfortably below the current rate, meaning the chase is on track.
Frequently asked questions
How should I enter overs like "20.3"?
On a scorecard 20.3 means 20 completed overs and 3 balls of the next. This calculator treats the number as decimal overs, so for exact ball-level precision convert balls to a fraction of six (3 balls = 0.5 over) before entering. For whole overs just enter the number.
What does it mean when the required rate exceeds the run rate?
The chasing team is behind the pace needed to win and must score faster than they have been. A gap of a run or two is manageable; a large and growing gap, especially with few wickets in hand, signals the chase is slipping away.
Is this the same as net run rate?
No. Net run rate (NRR) is a tournament tiebreaker comparing a team’s scoring rate across matches against the rate they concede. This calculator handles a single innings — current and required rates within one game.
