Average Calculator (Mean, Median, Mode)
Mean, median, mode, range and sum from a list of numbers.
Average Calculator takes a list of numbers pasted in any format — commas, spaces or one per line — and returns the mean, median, mode, range, sum, count, minimum and maximum. It also computes a weighted mean when you supply weights. All arithmetic happens in your browser.

Questions about Average Calculator (Mean, Median, Mode)
When should I use the median instead of the mean?
Whenever the data has outliers or a skewed shape — incomes, house prices, response times. One extreme value drags the mean but barely moves the median, which is why official statistics quote median income.
What if there is no mode?
The tool says so. When every value appears once there is no mode, and when several tie it reports all of them rather than picking one arbitrarily.
How is a weighted mean computed?
Each value is multiplied by its weight, the products are summed, and the total is divided by the sum of the weights — the same arithmetic behind a GPA or a portfolio return.
How messy can the pasted list be?
Spaces, commas, semicolons, tabs and line breaks all work as separators, and a thousands separator inside a number such as 1,234 is read correctly. Currency symbols and text labels are not stripped — anything that is not a number is left out of the totals and listed back to you in a warning.
How many numbers can I paste in?
Tens of thousands compute without a pause, since the work is a couple of passes over the list. The ceiling is your device rather than a server quota, and there is no upload step to wait through — the text goes straight from the box into the arithmetic.
Is Average Calculator (Mean, Median, Mode) really free, with no limits?
Yes. There is no account, no daily cap, no file-size tier and no watermark, because there is no server cost to recover. The site is funded by clearly disclosed partner recommendations on the Partners page, never by metering the tools.
Are my files or text uploaded when I use Average Calculator (Mean, Median, Mode)?
No. Everything is processed by JavaScript running in your browser, on your device. You can verify it: open your browser's developer tools, switch to the Network tab, and use the tool. You will see no request carrying your data — because there is nowhere for it to go.
