The arithmetic mean is sum ÷ count. Paste a list to get the mean plus sum, count, min, max, and range in one summary.

An average calculator computes the mean, median, mode, sum, range, minimum, and maximum for a list of numbers — giving a full statistical summary instantly.
Separate values with commas, spaces, or line breaks. Empty tokens and non-numeric text are ignored.

Enter at least one valid number to see mean, median, mode, and spread stats.
An average calculator takes a list of numbers and returns several statistical measures simultaneously. The mean (arithmetic average) is the sum divided by the count. The median is the middle value when sorted — more resistant to outliers than the mean. The mode is the most frequently occurring value.
Knowing which measure to use matters: the mean is affected by extreme values, so a salary dataset with a few million-dollar earners will have a mean far higher than what most people actually earn. The median is a better 'typical value' in skewed distributions. Many real-world datasets — house prices, incomes, test scores — require both mean and median to be properly understood.
We parse the entered values, compute arithmetic mean, median from sorted values, and mode from frequency counts, plus min/max and range.
Formula
Mean = (Σx) ÷ n
Median = middle(sorted(x)) (or average of two middle values)
Mode = most frequent value(s)
Range = max − minLoad Average Calculator on EverydayTools—no account required.

Input
72, 85, 91, 78, 88, 85Output
Mean: 83.2 · Median: 86.5 · Mode: 85 · Min: 72 · Max: 91The mode (85) appears twice. The median (average of the two middle values when sorted: 85 and 88) is 86.5 — slightly higher than the mean because the low score (72) pulls the mean down.
Input
38000, 42000, 45000, 41000, 39000, 250000Output
Mean: $75,833 · Median: $41,500One executive salary ($250,000) inflates the mean to $75,833 — far above what any typical employee earns. The median ($41,500) is a much better representation of the typical salary in this dataset.
Common real-world scenarios where this tool saves time.

Average monthly revenue figures, sales counts, customer ratings, or transaction values to identify trends across reporting periods.
Compute the mean and median of survey responses, experimental measurements, or sample data during analysis without opening a spreadsheet.
Calculate averages for batting averages, race times, lap speeds, or match scores across a season or competition series.
The most common measures of central tendency and when to use each.
| Measure | Definition | Formula / Method | Best Used When |
|---|---|---|---|
| Mean (Average) | Sum divided by count | Σx ÷ n | Data is roughly symmetric with no extreme outliers |
| Median | Middle value when sorted | Middle value (or avg of two middle values) | Data has outliers or is skewed (e.g. income, house prices) |
| Mode | Most frequently occurring value | Value that appears most often | Categorical data or finding the most common result |
| Weighted Mean | Average where values have different weights | Σ(value × weight) ÷ Σweights | GPA, survey responses with different sample sizes |
| Geometric Mean | nth root of product of n values | (x₁ × x₂ × … × xₙ)^(1/n) | Growth rates, ratios, multiplicative data |
The arithmetic mean is pulled toward outliers. If you have extreme values, the median is often a better "typical" value.

Mean (arithmetic average) = sum of all values ÷ count of values. Median = the middle value when numbers are sorted; for even counts, it's the average of the two middle values. Mode = the most frequently occurring value. Example: for [2, 3, 3, 5, 7]: mean = 4.0, median = 3, mode = 3.
Use median when your data contains outliers that skew the average. For example, household income data: if most households earn $40,000–$80,000 but a few earn $5 million, the mean is misleadingly high. The median better represents the typical household. Real estate prices, salaries, and income distributions often use median for this reason.
Yes. The calculator accepts integers, decimals (e.g. 3.14), and negative numbers. Separate values with commas, spaces, or line breaks.

Range = maximum − minimum value. It measures the spread of your data. A mean of 80 from scores of 78–82 tells a very different story from scores of 50–100 that also average 80. Always report range alongside the mean to give context about variability.
Yes. If every value in the dataset appears exactly once, there is no mode. Some datasets have multiple modes — called bimodal (two modes) or multimodal (three or more). For example, [1, 2, 2, 3, 3] has two modes: 2 and 3.
A weighted average assigns different importance to values: Weighted mean = Σ(value × weight) ÷ Σweights. Example: a course where homework (40%) and exams (60%) have different weights — a 90 homework grade and 70 exam grade gives 0.4×90 + 0.6×70 = 36 + 42 = 78, not the arithmetic mean of 80.
