Min Max Average Calculator
Paste numbers, read the whole summary
Paste a list of numbers from a spreadsheet, a log or a message and get the count, sum, mean, median, minimum, maximum, range, standard deviation and percentiles together.
One per line, or separated by commas, spaces or semicolons.

What this tool does
This is the summary you would otherwise build in a spreadsheet from six separate formulas, for the times when the numbers are in a chat message rather than in a sheet. Paste them in any shape: one per line, comma separated, tab separated from a spreadsheet column, or all on one line. Anything that is not a number is set aside and listed rather than silently counted as zero, because a stray label quietly becoming a zero is what makes an average wrong in a way nobody notices. Alongside the average you get the median, which is the figure to quote when one outlier is dragging the mean away from what is typical, and the quartiles that show how spread out the list really is.
How to use it
- Paste or type your numbers, one per line or separated by commas.
- Read the average, median, minimum, maximum and percentiles.
- Copy the summary, or the sorted list, for your notes.

Frequently asked questions
- Are my numbers uploaded?
- No. Everything is calculated in the page, which is why the summary updates as you type. Nothing is sent, stored or logged.
- Why is 1,234 read as two numbers?
- Because a comma is treated as a separator, which is what a pasted list needs. Remove thousands separators, or paste one number per line, and the value stays whole.
- Mean or median?
- The mean uses every value, so a single very large figure pulls it upwards. The median is the middle value and ignores how extreme the extremes are, which makes it the better summary of a skewed list such as prices or response times.
