iHow it is calculated

The average is the arithmetic mean of your grades — add them all up and divide by how many there are:

average = sum of grades ÷ number of grades

For grades 72, 65, 80, 78: (72 + 65 + 80 + 78) ÷ 4 = 295 ÷ 4 = 73.75.

How do I calculate a subject average?

Add up all the grades for that subject and divide by the number of grades. The result is the arithmetic mean.

What if some assessments count more than others?

Then you need a weighted average, not a simple mean. Use the weighted average calculator and enter each grade with its weight.

Does this round to a whole number?

No — a subject average normally keeps its decimals. This tool shows the mean to two decimal places.

Can I use percentages or points?

Yes. The average works with any consistent scale — percentages (0–100), points, or a 0–10 scale.

How is a term average different from a final grade?

A term average is the mean of the grades in that term. A final grade may combine several terms or apply weightings set by the school.
