Average Calculator

Enter numbers separated by commas, spaces or new lines. You get the mean along with the median, mode and range, which together tell you far more than the average alone.

What it is:: An average calculator that reports more than the mean.
What it calculates:: Mean, median, mode, sum, count and range for any list of numbers.

Key Assumptions

Values are read from commas, spaces, semicolons or new lines.
A mode is only reported when a value repeats.
Non-numeric entries are ignored.

How does the Average Calculator work?

The mean is the sum divided by the count. The median is the middle value once the numbers are sorted, which is more reliable when a few extreme values would drag the mean around.

A mode is only reported when at least one value repeats.

Worked example: for 12, 15, 18, 20 and 35 the sum is 100 and the count is 5, so the mean is 20. The median, the middle value once sorted, is 18. The single large value, 35, pulls the mean above the median, which is the usual sign that the median describes the typical value better.

A weighted average gives some values more importance than others. The most common example in India is the average price of shares bought at different prices: multiply each price by the number of shares bought at it, add those up, and divide by the total number of shares; the Stock Average Calculator does this for you and shows how buying more changes the average. For returns on investments, the CAGR Calculator and Percentage Calculator are usually the right tools.

Average Calculator formula

Mean = sum of values / count of values

sum: = all values added together
count: = how many values there are

Count: 6
Sum: 155
Mean: 25.83
Median: 25.00
Mode: 25
Range: 32 (12 to 44)

Average Calculator: frequently asked questions

When should I use the median instead of the mean?

When a few very large or very small values would distort the picture, such as incomes or house prices. The median describes the typical value better.

What is the mode when no number repeats?

When no number in a list repeats, the list has no mode, because the mode is the value that appears most often. The average calculator reports that there is no mode rather than picking an arbitrary value.

Can I paste a column from a spreadsheet?

Yes, you can paste a spreadsheet column: values separated by new lines, commas, spaces or semicolons are all read correctly, and anything that is not a number is ignored.

How is the average calculated?

Add all the numbers and divide by how many there are. For 12, 15, 18, 20 and 35, the sum is 100 and there are 5 numbers, so the average is 20.

How do I calculate the average price of shares?

Use a weighted average. Multiply each purchase price by the number of shares bought at that price, add the results, and divide by the total number of shares. For example, 100 shares at ₹500 and 50 shares at ₹440 cost ₹72,000 for 150 shares, an average of ₹480 a share.
