Average Calculator
Paste any list of numbers — test scores, expenses, measurements — and get the mean, median, and mode together, plus count and sum. The fastest way to summarize

How to use this calculator
- Paste or type your numbers, separated by commas, spaces, or new lines.
- See the mean, median, mode, count, and sum instantly.
The formulas
Mean = sum of values ÷ count. Median = middle value of the sorted list (average of the two middle values when the count is even). Mode = most frequently occurring value.
Worked example
Scores 4, 8, 6, 5, 3: sum = 26, count = 5, mean = 5.2, median = 5 (middle of sorted 3,4,5,6,8), mode = none (no repeats).
About this tool

Frequently asked questions
Mean vs. median — which is better?
The mean uses every value, so one billionaire in a room of interns skews it. The median (middle value) resists outliers — that's why incomes are usually reported as medians.
What if no number repeats?
Then there is no mode — the calculator will tell you so. Some datasets have two modes (bimodal).
What about a weighted average?
Use our GPA calculator — it weights each grade by credit hours, which a plain average can't do.
How many numbers can I enter?
As many as you like — paste hundreds separated by commas, spaces, or new lines.
