Cricket Run Rate Calculator
Calculate current run rate, required run rate, and match projections for cricket innings.

How to use this calculator
Fractional overs are converted by adding balls/6. Current run rate divides runs scored by overs bowled. Required run rate divides runs needed by overs remaining.
- 1
Select whether you want Current Run Rate or Required Run Rate.
- 2
Enter the runs scored and overs bowled (plus any additional balls).
- 3
For Required Run Rate, also enter the target and overs remaining.
- 4
Read the calculated run rates and projected match total.
Frequently asked questions
How is the current run rate calculated?
This tool uses runs scored ÷ overs bowled, where overs bowled is the whole overs plus balls ÷ 6. 120 runs after 15 overs is 8.00 runs per over. With zero overs bowled the calculator shows “n/a (no overs bowled)”.
How is the required run rate calculated?
Runs still needed ÷ overs remaining, with runs needed equal to the target minus runs scored (never below zero). A target of 250 with 120 scored and 20 overs left leaves 130 runs and a required rate of 6.50. If the target has already been reached, the required rate shows 0.00.
What should I enter as the target?
Enter the total your side needs to reach, the figure you are measuring against. If the opposition made 180 and you need to win, the target to enter is 181. The calculator does not add the extra run for you; it simply subtracts your score from whatever target you type.
Why does 10 overs and 3 balls show as 10.5 overs?
The “Overs Bowled” line is a decimal number of overs, where 3 balls is 0.5 of an over. Cricket scorecards write the same position as 10.3. The calculator uses the decimal form for its arithmetic, so 15 overs and 4 balls reads 15.7, not 15.4. Ball fields accept 0 to 5, and larger entries are capped at 5.
How is the projected total worked out?
In current-run-rate mode the tool multiplies the current run rate by the total overs, which is overs bowled plus overs remaining, and rounds to a whole number. 87 runs after 10.5 overs, with 9.5 left, projects to 166. It assumes the rate stays constant, and it takes no account of wickets lost.
What if there are no overs remaining?
The required rate and the run-rate gap show “n/a”. The runs needed are still displayed, so you can see how far short the innings is. There is no division by zero and no misleading 0.00.
What does it leave out?
Wickets in hand, powerplay or field-restriction phases, the Duckworth–Lewis–Stern method for rain-affected matches, and net run rate across a tournament are not part of this tool. It is the plain arithmetic of runs, overs and a target.
Cricket run rate calculator: current, required and projected
Two rates and the gap between them
Run rate is runs per over. The current run rate describes what the batting side has done, and the required run rate describes what it must do from here to reach a target. Comparing them tells you whether the chase is ahead or behind the asking rate. The calculator offers both in separate modes and converts partial overs by treating each ball as one sixth of an over, so 3 balls is 0.5 of an over.
| Mode | Output | Formula |
|---|---|---|
| Current run rate | CRR | Runs scored ÷ overs bowled |
| Current run rate | Projected total | CRR × (overs bowled + overs remaining), rounded |
| Required run rate | RRR | (Target − runs scored) ÷ overs remaining |
| Required run rate | Gap | RRR − CRR |
Worked example: current run rate and projection
A side on 120 after 15 overs is scoring at 8.00. With 20 overs still to bowl, the projected total at that rate is 280, which is 8.00 times 35 overs. A second innings, 87 after 10 overs and 3 balls, has overs bowled of 10.5 in decimal form and a run rate of 8.29. With 9 overs and 3 balls left, projecting at that rate gives 166. Projections like these are a straight-line extrapolation, so an acceleration or a collapse will make them miss.
| Runs | Overs bowled (decimal) | Overs remaining (decimal) | CRR | Projected total |
|---|---|---|---|---|
| 120 | 15.0 | 20.0 | 8.00 | 280 |
| 87 | 10.5 | 9.5 | 8.29 | 166 |
Worked example: a chase
Needing 250 with 120 on the board and 20 overs remaining, the side needs 130 more at 6.50 an over. Its current rate is 8.00, so the gap (required minus current) is −1.50: the chase is running ahead of the asking rate. A tighter chase puts 142 on the board after 16 overs and 2 balls, aiming for 181 with 3 overs and 4 balls left. That needs 39 runs at 10.64 per over against a current 8.69, a gap of 1.94 in the bowlers’ favour.
| Scored | Target | Overs left (decimal) | Needed | RRR | CRR | Gap |
|---|---|---|---|---|---|---|
| 120 | 250 | 20.0 | 130 | 6.50 | 8.00 | −1.50 |
| 142 | 181 | 3.7 | 39 | 10.64 | 8.69 | 1.94 |
Reading the gap
A negative gap means the batting side is already scoring faster than it needs to, a positive gap means it has to speed up. The size of the gap reads differently at different stages: 2 runs per over adds up to 40 runs across 20 overs but only 6 runs across 3 overs. The tool does not model wickets or field restrictions, so treat the gap as a starting point.
Limits
The calculator does not track wickets, balls remaining beyond the five-ball field, or revised targets after rain. For rain-affected matches the official method sets its own target. Net run rate for league tables is a different calculation, comparing rates scored and conceded across a whole tournament, and it is not produced here.
