In every run chase, the required run rate, or asking rate, tells the batting side how fast it must score to win. Commentators show it on screen constantly because it captures pressure in a single number. This guide explains how to calculate required run rate with examples, using our free Required Run Rate Calculator.
The formula
Required run rate (RRR) = Runs needed ÷ Overs remaining
Runs needed = Target − Current score
Remember that the target is one more than the first team’s total.
Converting overs remaining
If 13.2 overs have been bowled in a 20-over innings, overs remaining = 20 − 13.2. In balls: 120 − 80 = 40 balls, which is 6.667 overs (shown as 6.4 in cricket notation).
Worked examples
- T20: Target 171. Score 95 after 12 overs. Needed 76 from 8 overs. RRR = 76 ÷ 8 = 9.50.
- ODI: Target 281. Score 150 after 30 overs. Needed 131 from 20 overs. RRR = 6.55.
- Tight finish: Needed 22 from 13 balls. RRR = 22 ÷ 13 × 6 = 10.15.
How the asking rate climbs
If the batting side falls behind, the RRR rises quickly. Example: needing 90 from 10 overs (RRR 9.0):
| After over | Runs scored that over | Needed | Overs left | New RRR |
|---|---|---|---|---|
| 11 | 6 | 84 | 9 | 9.33 |
| 12 | 5 | 79 | 8 | 9.88 |
| 13 | 12 | 67 | 7 | 9.57 |
| 14 | 4 | 63 | 6 | 10.50 |
Comparing with current run rate
If the current run rate is higher than the required run rate, the chase is on track. If it is lower, the batting side needs to accelerate. Check current scoring with the Run Rate Calculator.
Wickets matter
RRR does not account for wickets in hand. Needing 9 an over with 8 wickets left is very different from the same rate with 2 wickets. Use the Cricket Score Predictor to see possible totals.
Rain-reduced matches
When overs are lost, targets are revised using the DLS method, and the asking rate changes. Read chasing strategy and the required run rate, and see the Cricket Target Calculator.
Frequently asked questions
What is the required run rate?
Runs needed divided by overs remaining.
How do I calculate RRR from balls?
Runs needed ÷ balls remaining × 6.
Does RRR include wickets?
No, it only considers runs and overs.
