Cricket Run Rate Calculator
Compute CRR (current run rate) for any innings and RRR (required run rate) when chasing a target. Format-aware: T20 (20 overs), ODI (50 overs), Test (no over limit).
CRR vs RRR — the formulas
Current Run Rate (CRR) = runs scored ÷ overs bowled, expressed as runs per over. So 120 runs in 15 overs = CRR 8.0.
Required Run Rate (RRR) = runs still needed ÷ overs remaining. Chasing 180 with 120 in 15 overs (T20) means you need 60 more runs in 5 overs = RRR 12.0. That's the “asking rate” on the scoreboard.
Why overs are written as “15.3”, not 15.5
Cricket overs are base-6, not base-10. 15.3 means 15 overs and 3 balls, i.e. 93 balls bowled. So a CRR over 15.3 overs is runs × 6 ÷ 93, not runs ÷ 15.5. Most online calculators get this wrong and show inflated rates. This one converts overs to balls correctly before dividing.
Reading RRR in a T20 chase
- RRR < 6 — easy chase, batting team can take it slow
- 6–8 — standard pace, on track
- 8–10 — pressure, needs sustained hitting
- 10–12 — tough, needs a partnership of boundaries
- 12–15 — almost impossible, needs huge overs
- > 15 — statistically lost (with rare exceptions)
For ODI cricket, halve these thresholds.
NRR (Net Run Rate) for tournament tiebreakers
IPL and World Cup group-stage ties are broken by NRR = (runs scored ÷ overs faced) − (runs conceded ÷ overs bowled). A team with NRR +1.5 scored on average 1.5 runs more per over than they conceded. Winning by big margins and bowling out the opposition early are the levers — close games barely move NRR.

FAQ
Run rate vs required run rate?
Run rate (RR) = current rate per over (runs / overs). Required (RRR) = target gap ÷ overs left. Watch the spread — high RRR with low RR means the chase is slipping.
D-L (Duckworth-Lewis) when relevant?
Rain-affected innings. DLS revises target based on resources used (overs + wickets). Our DLS calculator handles this. Run rate alone doesn't adjust for interruptions.
Asking rate vs hitting rate — different?
Same concept. Required Run Rate (RRR) is the most common term in commentary. "Asking rate is climbing" means RRR is rising — bad for the chasing team.
