Average Calculator

Published on: July 20, 2025

Enter a list of numbers separated by commas (e.g., 3, 1, 4, 2) to compute their average.

Step-by-step method

  1. List the numbers and count how many there are.
  2. Add the numbers to get the total sum.
  3. Divide the sum by the count to get the average.

Formula:

Average=
Σx
n

Example 1: 3, 1, 4, 2

Step 1 - List the numbers and count how many there are.

In this problem: The numbers are 3, 1, 4, 2, so the count is n = 4.

n=4

Step 2 - Add the numbers to get the total sum.

In this problem: Add the numbers to get the sum: Σx = 10.

Σx=10

Step 3 - Divide the sum by the count to get the average.

In this problem: Divide the sum by the count: Average = 10 ÷ 4 = 2.5.

Average=
10
4
=2.5

Final answer: Average = 2.5

Example 2: 10, 20, 30, 40, 50

Step 1 - List the numbers and count how many there are.

In this problem: The numbers are 10, 20, 30, 40, 50, so the count is n = 5.

n=5

Step 2 - Add the numbers to get the total sum.

In this problem: Add the numbers to get the sum: Σx = 150.

Σx=150

Step 3 - Divide the sum by the count to get the average.

In this problem: Divide the sum by the count: Average = 150 ÷ 5 = 30.

Average=
150
5
=30

Final answer: Average = 30
