Cricket calculator

Every calculation on a cricket scorecard, one page at a time. Batting average and strike rate, bowling average, economy and strike rate, run rate and the asking rate in a chase, tournament net run rate, and a Duckworth-Lewis-Stern par score. Each converts overs properly — 9.3 is fifty-seven balls, not nine point three — which is where most hand calculations and most spreadsheets quietly go wrong.

Batting

Batting averageHow many runs a batter makes before getting out.Batting average = runs scored ÷ (innings batted − not outs)Batting strike rateHow quickly a batter scores, per 100 balls faced.Strike rate = (runs scored ÷ balls faced) × 100

Bowling

Bowling averageWhat each wicket costs a bowler in runs.Bowling average = runs conceded ÷ wickets takenBowling strike rateHow many deliveries a bowler needs per wicket.Bowling strike rate = balls bowled ÷ wickets takenEconomy rateHow many runs a bowler leaks per over.Economy rate = runs conceded ÷ overs bowled

Team and match

Run rateHow fast an innings is scoring, per over.Run rate = runs scored ÷ overs facedRequired run rateWhat the chasing side needs per over from here.Required run rate = runs still needed ÷ overs remainingNet run rateThe tiebreaker that settles a points table.NRR = (runs scored ÷ overs faced) − (runs conceded ÷ overs bowled)Projected scoreWhere this innings lands at the current rate.Projected score = current runs + (current run rate × overs remaining)NRR after this matchWhat one result does to your net run rate.New NRR = (all runs scored ÷ all overs faced) − (all runs conceded ÷ all overs bowled)NRR margin neededThe margin you need to reach a target net run rate.Solve the net run rate equation for the one unknown: the margin, or the overs the chase takes.

Rain and conversion

Overs to ballsWhy 12.3 overs is 75 balls and not 12.3.Balls = (whole overs × 6) + balls after the decimal pointDLS par scoreThe rain-revised target, and what par really means.Par = score × (R2 ÷ R1) when R2 is below R1, or score + G50 × (R2 − R1) ÷ 100 when R2 is above it. Target is one more than par.

Questions

Cricket maths, answered

What can you calculate with a cricket calculator?

Everything on a scorecard that is a division. Batting average and strike rate, bowling average, strike rate and economy, the run rate of an innings, the required run rate in a chase, a projected total, tournament net run rate, and a Duckworth-Lewis-Stern par score. Each one has its own page here with the formula and a worked example.

How do you calculate batting average and strike rate?

Batting average is runs divided by dismissals, where dismissals are innings batted minus not outs — not runs divided by innings, which is the usual error. Strike rate is runs divided by balls faced, multiplied by 100, so it reads as runs per 100 balls.

Why do cricket calculations go wrong with part overs?

Because cricket writes 9.3 to mean nine overs and three balls, and that is not nine point three. It is 57 balls, or 9.5 as a decimal. Dividing by 9.3 instead of 9.5 makes every rate slightly wrong, and it is the single most common mistake in cricket arithmetic. Every calculator here converts the notation before dividing.

How is net run rate calculated?

Run rate scored minus run rate conceded, summed across every completed match of the tournament rather than averaged match by match. The clause that catches people out is that a side bowled out counts its full quota of overs, not the overs it actually faced.

Are these calculators free to use?

Yes, all of them, with nothing to install and no sign-in. They run entirely in your browser, so the numbers you type are never sent anywhere.

Do the calculators work on a phone during a match?

Yes. Each one is a single screen with a numeric keypad, and the answer updates as you type rather than behind a button, so you can nudge a number and watch the figure move.
