About this tool
The Net Run Rate Calculator computes cricket's NRR, the tie-breaker used to separate teams level on points in a league table. The formula is straightforward: NRR = (total runs scored / total overs faced) − (total runs conceded / total overs bowled). A positive NRR means a team scores faster than it concedes; a negative NRR means the opposite.
Overs are entered in the standard 6-ball notation, where the decimal counts balls rather than tenths: 19.3 overs is 19 overs and 3 balls, which the tool converts to 19.5 in true decimal before dividing. A crucial rule is built in: when a team is bowled out, its overs faced count as the full allotment (for example 50 in an ODI or 20 in a T20), not the fewer overs it actually batted. Tick the “all out” box for either innings and enter the allotted overs to apply this correctly.
Everything runs locally in your browser, so nothing you enter is uploaded. The tool reports the Net Run Rate along with each side's run rate and the effective overs used, so you can see exactly how the figure was built. To combine several matches into a tournament NRR, sum all runs scored, overs faced, runs conceded, and overs bowled across the matches and enter those totals — NRR is calculated once from the aggregate, never by averaging the per-match figures.
