How is net run rate calculated in cricket?

NRR is the average runs per over a team scores across the tournament minus the average runs per over scored against it. Add up all runs scored and divide by total overs faced; do the same for runs conceded over total overs bowled; subtract the second from the first. Overs are aggregated across every completed match, not averaged per game.

What happens to NRR when a team is all out?

Per the ICC Playing Conditions, a side bowled out is treated as having batted its full quota of overs — 50 in an ODI, 20 in a T20 — regardless of when the last wicket fell. So if you bowl a team out for 150 in 18 overs of a T20, you still divide their 150 by 20, not 18. This calculator applies that rule automatically when you tick the all-out box.

How do you count overs when a team is bowled out early?

You do not use the over at which they were dismissed. The all-out innings is scored against the full format quota. Only the batting or bowling side that was actually dismissed gets its overs expanded to the quota — the other innings keeps its real overs.

Why is 45.3 overs not 45.3 in the maths?

Cricket overs are base-6: an over is six legal balls. The notation 45.3 means 45 completed overs and 3 balls, which as a decimal is 45 + 3/6 = 45.5 overs. Treating 45.3 as the decimal 45.3 is the most common NRR error, and it changes the run rate. This tool converts O.B entries correctly.

Does a higher NRR mean a better team?

NRR is only a tie-breaker. Teams are ranked first on points; NRR separates sides level on points in the standings. A higher NRR means a team has, on balance, scored faster and conceded slower — but it never overrides a points difference.

How many overs must we win in to overtake a rival on NRR?

Use the chase-scenario mode. Enter the opponent's total and the single-match NRR you want, and it solves overs = runs-to-win ÷ (target NRR + opponent run rate), then rounds down to the last ball so finishing by that ball guarantees at least your target. It also flags when a target is impossible within the quota.

Are no-result or abandoned matches included in NRR?

No. The ICC excludes matches with no result from NRR entirely — neither the runs nor the overs count. Only enter completed matches in the tournament mode. Rain-affected games that still produced a result are included using the actual runs and overs (or a DLS-adjusted total where one applies).

Does this calculator handle Duckworth–Lewis–Stern (DLS)?

Not yet. DLS par-score targets need the licensed resource tables, which are not fully public, so a separate tool is planned. For NRR you only need the published formula, which this tool implements. If a match was decided by DLS, enter the actual runs scored and overs faced as recorded in the scorecard.

Enter the runs scored.
Enter the runs conceded.
Overs faced: Enter the overs, e.g. 45.3 for 45 overs and 3 balls.
Overs bowled: Enter the overs, e.g. 45.3 for 45 overs and 3 balls.

Enter at least one completed match — runs and overs for both innings — to see your Net Run Rate.

Formula and rules from the ICC Men's Playing Conditions (Net Run Rate appendix). A side that is all out counts as having batted the full quota of overs. Last verified 2026-07-08.

How it works

Net Run Rate (NRR) is the tie-breaker cricket tournaments use to separate teams level on points. The Sri Lanka fan doing group-stage maths during the Asia Cup or a World Cup needs two things right: the all-out rule and the base-6 overs conversion. This calculator follows the definition in the ICC Men's Playing Conditions exactly.

Convert overs to decimal. An over is six legal balls, so overs are base-6, not base-10. An entry written as O.B (O whole overs, B balls, 0–5) becomes O + B/6. So 45.3 overs is 45 + 3/6 = 45.5 decimal overs.
Apply the all-out rule. The ICC conditions state a team that is all out is treated as having batted its full quota of overs. When you tick the all-out box, the calculator forces that innings to 50 overs (ODI), 20 (T20) or your custom quota, whichever team was dismissed — independently for the batting and bowling sides.
Aggregate across matches. Run rate for is the total runs you scored divided by the total overs you faced across every completed match; run rate against is total runs conceded divided by total overs bowled. Overs are summed, never averaged per game.
Subtract. NRR = run rate for − run rate against, shown to three decimals with an explicit sign.

The formal statement is NRR = Σ(runs for)/Σ(overs faced) − Σ(runs against)/Σ(overs bowled), with all-out innings expanded to the quota before summing. No-result matches are excluded entirely — the runs and the overs both drop out — so the tournament mode asks you to enter completed matches only.

The chase mode inverts the single-match version of the same formula. If you bat second and must score T runs to win against an opponent who made R in Q effective overs, your single-match NRR is T/o − R/Q. Solving for the overs o that reach a desired NRR d gives o = T / (d + R/Q). The tool rounds that down to the last whole ball, so completing the chase on or before that ball guarantees at least your target — and it flags cases that are impossible within the quota.

Worked examples

Tournament NRR — T20 with the all-out rule

Match 1: scored 180 in 20.0; bowled opponent out for 150 in 18.0.
All-out rule → opponent's overs become the full 20.0, not 18.0.
Match 2: scored 165 in 20.0; conceded 160 in 20.0 (neither all out).
Runs for = 180 + 165 = 345 over 40.0 → 8.625 per over.
Runs against = 150 + 160 = 310 over 40.0 → 7.750 per over.
NRR = 8.625 − 7.750 = +0.875

Chase scenario — ODI, overs needed

Opponent all out for 173 → effective overs Q = 50, rate = 173/50 = 3.460.
You need 174 to win. Target single-match NRR d = +2.00.
Overs o = 174 / (2.00 + 3.460) = 174 / 5.460 = 31.868 decimal overs.
Round down to the ball: 31 overs, 5 balls → 31.5 (= 31.833 decimal).
Check: 174 / 31.833 − 3.460 = 5.466 − 3.460 = +2.006 ≥ +2.00

Edge case — a target NRR that is impossible

ODI, opponent all out for 100 → Q = 50, rate = 2.000. You need 101 to win.
You want a modest single-match NRR of exactly 0.00.
Overs o = 101 / (0.00 + 2.000) = 50.5 overs — more than the 50-over quota.
Even batting the full 50 overs gives 101/50 − 2.000 = +0.020, above 0.00.
So +0.00 is unreachable here — the tool flags it and shows the minimum you will beat.
