Page guide

Find the average when some values count more than others.

How to use Weighted average calculator
  1. Enter one value and its weight per line, separated by a comma. A weight can be a count, a percentage or relative importance. The weights do not have to add up to 100.
  2. A score of 80 with weight 1 and a score of 90 with weight 3 give a weighted average of 87.5. The weighted sum is 350 and the total weight is 4.

Give each value its weight

Enter one value and its weight per line, separated by a comma. A weight can be a count, a percentage or relative importance. The weights do not have to add up to 100.

Try a small example

A score of 80 with weight 1 and a score of 90 with weight 3 give a weighted average of 87.5. The weighted sum is 350 and the total weight is 4.

What to know

Supports up to 1,000 rows. Values and weights must be finite and no larger than 1 trillion in magnitude. Weights cannot be negative and at least one must be positive. Zero weights exclude a value from the average. Results use 12 significant digits.
