When this tool is useful

An average calculator is useful for a quick mean from test scores, measurements or repeated observations. It treats each number equally; use a weighted-grade tool when values should contribute different amounts.

How to use it

  1. Enter the numbers you want to average, separated in the format the tool accepts.
  2. Calculate the arithmetic mean and review the count of values included.
  3. Check that blank entries, repeated numbers and units are handled as intended.

Common uses

  • Finding an average score or measurement
  • Summarising a short list of values
  • Checking a mean before reporting results

Tips for a reliable result

Tips for a reliable result

Use values measured in comparable units. A single unusually high or low value can pull the arithmetic mean away from the middle of the data, so consider whether a median would also help.

Frequently asked questions

How do I calculate an average?

Add all values and divide the sum by the number of values. Enter the numbers separated by commas or new lines.

Is average the same as median?

No. This calculator reports the arithmetic mean. The median is the middle value after sorting, which is not calculated here.

Can I average class grades?

Yes, if every score should count equally. If assignments have different weights, use a weighted grade or class grade calculator.
