Average Calculator: How to Calculate an Average

Averages play a crucial role in education, sports, finance, and health. Whether you’re tracking your grades, cricket batting average, stock investments, or blood pressure, understanding how to calculate an average can help you make better decisions.

This guide explains different types of averages with practical examples. If you need quick results, try our online average calculator—it does the maths for you!

How Do We Calculate an Average?

To find an average, simply add all the values together and divide by the total number of values.

Formula:
Average = (Sum of Values) ÷ (Number of Values)

For example

You're reviewing test scores from your uni exams. You scored 75, 82, and 89 in three subjects.

(75 + 82 + 89) ÷ 3 = 246 ÷ 3 = 82

Your average score is 82, meaning you've performed well across all subjects.

How to Calculate a Weighted Average?

A weighted average considers different levels of importance (weights) assigned to each value. To calculate it:

• Multiply each value by its weight.
• Add all the results together.
• Divide by the total sum of the weights.

Weighted Average Calculator

If a student scores 60 on one test (weight = 2) and 80 on another test (weight = 3), the weighted average is:

((60 × 2) + (80 × 3)) ÷ (2 + 3) = (120 + 240) ÷ 5 = 72

Weighted averages are widely used in education, finance, and data analysis. If you want some quick calculations done, simply use our weighted average calculator.

How to Calculate a Moving Average?

A moving average helps identify trends by smoothing out short-term fluctuations in data. It’s commonly used in stock market analysis and business forecasting.

Steps to Calculate a Simple Moving Average (SMA):

• Choose a window size (e.g., 3 days, 5 days, etc.).
• Calculate the average of the first set of values within the window.
• Slide the window forward and calculate new averages.

For example

Stock prices over 5 days: 20, 22, 21, 23, 25

For a 3-day moving average:

• First SMA: (20 + 22 + 21) ÷ 3 = 21
• Second SMA: (22 + 21 + 23) ÷ 3 = 22
• Third SMA: (21 + 23 + 25) ÷ 3 = 23

This technique helps businesses and investors spot long-term trends.

How to Calculate a Grade Average?

If you’re a student, knowing your grade average helps track academic performance.

Formula:
Grade Average = (Sum of All Grades) ÷ (Total Number of Subjects)

Grade Average Calculator

Sarah is in her final year of high school and wants to estimate her ATAR score. Her grades are:

• Maths: 85
• English: 90
• History: 88
• Science: 80

(85 + 90 + 88 + 80) ÷ 4 = 85.75

Sarah’s grade average is 85.75, which puts her in a strong position for university admissions. If you want to quickly calculate your average grade, simply use our grade average calculator.

How to Calculate a Grade Point Average (GPA) in Australia?

Unlike the 4.0 GPA scale used in the US, Australian universities often use a 7.0 GPA scale. The conversion generally follows this pattern:

Steps to Calculate GPA:

• Convert each grade into a GPA value.
• Multiply each GPA value by the course’s credit points.
• Add all the weighted GPA values together.
• Divide by the total number of credit points.

Grade Point Average Calculator

Let's say you completed four subjects with the following results:

Mathematics: 6.0 GPA (3 credit points)Physics: 5.0 GPA (4 credit points)Chemistry: 7.0 GPA (3 credit points)English: 4.0 GPA (2 credit points)

Step 1: Multiply GPA by Credit Points

• Mathematics: 6.0 × 3 = 18
• Physics: 5.0 × 4 = 20
• Chemistry: 7.0 × 3 = 21
• English: 4.0 × 2 = 8

Step 2: Add the Weighted GPA Values

18 + 20 + 21 + 8 = 67

Step 3: Divide by Total Credit Points

Total Credit Points = 3 + 4 + 3 + 2 = 12

GPA = 67 ÷ 12 = 5.58

Final GPA: 5.58

Batting Average Calculator: How to Calculate a Batting Average?

You're watching Australia vs India at the MCG. Steve Smith walks in to bat, and the commentators discuss his batting average. But how is it calculated?

A batting average tells you how many runs a cricketer scores before getting out.

Formula:
Batting Average = Total Runs Scored ÷ Number of Times Dismissed

For example

Steve Smith has scored 1,200 runs in 25 innings but has been out 15 times:

Batting Average = 1,200 ÷ 15 = 80.0

His batting average is 80, showing that he’s an incredibly consistent run-scorer for Australia.

Bowling Average Calculator: How to Calculate a Bowler’s Performance?

You often see a bowling average pop up on the screen during a cricket match, or maybe you find yourself calculating it while comparing bowlers. But how is it actually determined?

A bowling average measures how many runs a bowler concedes per wicket taken. A lower average means the bowler is more effective at dismissing batters while keeping runs to a minimum.

Formula for Bowling Average:

Bowling Average = Total Runs Conceded ÷ Total Wickets Taken

Calculating a Bowling Average

Imagine you're watching Australia vs England in the Ashes. Mitchell Starc has bowled brilliantly, and you want to calculate his bowling average.

Match Statistics:

• Total Runs Conceded: 240
• Total Wickets Taken: 8

Bowling Average Calculation:

240 ÷ 8 = 30.0

Mitchell Starc’s bowling average for the match is 30.0, meaning he concedes 30 runs per wicket on average.

Stock Average Calculator: How to Calculate a Stock Market Average?

You're considering investing in ASX stocks and want to calculate the average price of the shares you've bought over time.

Formula:
Stock Average Price = (Total Cost of Shares) ÷ (Total Number of Shares Bought)

For example

You invest in BHP Group Ltd (ASX: BHP):

• Buy 10 shares at $50 each → Total Cost = $500
• Buy 20 shares at $40 each → Total Cost = $800

Stock Average Price = (500 + 800) ÷ (10 + 20) = 1,300 ÷ 30 = $43.33 per share

Your average price per share is $43.33, helping you track your investment cost.

How to Calculate a Time Average?

You're training for a marathon and want to know your average lap time over three sessions.

Formula:
Time Average = (Total Time) ÷ (Number of Events)

For example

Your last three laps took 4:50, 5:05, and 4:45 (in minutes and seconds). Converting to seconds:

• 4:50 = 290 seconds
• 5:05 = 305 seconds
• 4:45 = 285 seconds

(290 + 305 + 285) ÷ 3 = 880 ÷ 3 = 293.3 seconds = 4 minutes 53 seconds

Your average lap time is 4:53, helping you track progress.

How to Calculate a Percentage Average?

You’re a business owner analysing customer satisfaction surveys. You received customer ratings of 80%, 75%, and 90% in three different months.

Formula:
Percentage Average = (Sum of Percentages) ÷ (Number of Values)

So you average percentage = (80 + 75 + 90) ÷ 3 = 245 ÷ 3 = 81.7%

Your average customer satisfaction is 81.7%, showing positive business performance.

How to Calculate a Dice Average?

You're playing Monopoly with friends and wondering what number you’re most likely to roll with two dice.

For a six-sided die, each face has an equal chance (1, 2, 3, 4, 5, 6).

Formula:
Dice Average = (Sum of All Possible Outcomes) ÷ (Number of Outcomes)

For example

A six-sided die has outcomes 1 to 6:

(1 + 2 + 3 + 4 + 5 + 6) ÷ 6 = 21 ÷ 6 = 3.5

So, the average roll of a six-sided die is 3.5, meaning that over many rolls, you'll land close to this number.

How to Calculate Blood Pressure Average?

You're monitoring your blood pressure and want a reliable average reading.

Formula:
Systolic Average = (Sum of Systolic Readings) ÷ (Number of Readings)
Diastolic Average = (Sum of Diastolic Readings) ÷ (Number of Readings)

For example

Your blood pressure readings over three days:

• 118/75 mmHg
• 124/78 mmHg
• 121/72 mmHg

Systolic Average = (118 + 124 + 121) ÷ 3 = 121
Diastolic Average = (75 + 78 + 72) ÷ 3 = 75

Final average blood pressure = 121/75 mmHg

For accurate readings:
✔ Measure at the same times daily.
✔ Sit calmly for 5 minutes before measuring.
✔ Use a validated blood pressure monitor.

How to Calculate an Average in Excel?

You can also build your own average calculator on Excel in a few quick steps. 

Steps to Calculate an Average in Excel:

• Open an Excel spreadsheet and enter your data in a column.
• Select the cell where you want the result.
• Type: =AVERAGE(A1:A5) (assuming your data is in cells A1 to A5).
• Press Enter, and the average will be displayed.

For a weighted average, use:
=SUMPRODUCT(A1:A5, B1:B5) ÷ SUM(B1:B5)

Averages are used everywhere—from education and sports to finance and health. Whether you’re calculating your grades, batting stats, stock prices, or blood pressure, knowing how to find an average can help you make better decisions.
