Paste or type a list of numbers and get the average instantly, along with the sum, count, median, smallest and largest value, and the range between them. It all runs in your browser — nothing is uploaded — so it is fine for grades, expenses or measurements you would rather keep to yourself.
Separate with spaces or new lines. Use a comma or dot for decimals (6,5).

How it works
The average (arithmetic mean) is the sum of all values divided by how many there are. The tool also reports the median — the middle value once the list is sorted, which averages the two central values when the count is even — because the median is often more representative when a few outliers would drag the mean around.
Separate numbers with spaces, new lines, tabs or semicolons. A comma or dot is treated as a decimal point, so 6,5 and 6.5 both mean six-and-a-half; that is why numbers are not split on commas. Anything that isn’t a number is skipped and counted, so a stray label won’t break the result.
Practical examples
Averaging school grades
Paste 5 4 5 3 5 4 and the mean is 4.33, with a median of 4.5. Grades are a classic case where mean and median differ slightly — both are shown.
Monthly expenses
Enter 12500 9800 15200 11000 to see a mean of 12,125 and a range of 5,400 between your cheapest and priciest month — a quick read on how much they vary.
Measurements with decimals
Type 1,82 1,79 1,85 1,80 (heights in metres, Serbian decimal commas). The mean is 1.815 — the comma is read as a decimal, not a separator.
Frequently asked questions
What is the difference between mean and median?
The mean adds every value and divides by the count. The median is the middle value when the list is sorted. When a few very large or small numbers are present, the mean shifts toward them while the median stays put — comparing the two tells you whether outliers are skewing the average.
How do I separate the numbers?
Use spaces, new lines, tabs or semicolons. You can paste a whole column from a spreadsheet (one number per line) and it just works. Commas are read as decimal points, not separators.
Can I use decimal commas like 6,5?
Yes. A comma or a dot is treated as a decimal point, so 6,5 and 6.5 are identical. This is why the tool doesn’t split numbers on commas — it would clash with the Serbian decimal comma.
What happens to text or labels in my list?
Non-numeric tokens are skipped, and the tool tells you how many it ignored. So you can paste “Jan 120, Feb 95” and still get an average of the numbers, though it’s cleaner to paste numbers only.
What does “range” mean here?
The range is the largest value minus the smallest — a simple measure of spread. A small range means the numbers cluster together; a large one means they’re spread out. It doesn’t tell you about the distribution in between.
Is this a weighted average?
No, it is the plain (unweighted) mean, where every number counts equally. If your values have different weights — like credits per grade — a weighted-average calculator is the right tool; this one treats all entries the same.
How precise are the results?
Results are shown to up to four decimals to avoid floating-point noise, which is plenty for everyday use. The underlying calculation uses full precision; only the display is rounded.
Is there a limit to how many numbers I can enter?
No practical limit for normal use — paste hundreds of lines if you like. Everything is computed locally in your browser, so speed depends only on your device.
Are the numbers I paste stored anywhere?
No. The calculation runs entirely in your browser; nothing is uploaded, and analytics never sees your data.
