Paste the grades however they are written

The average of any list of grades, the distribution across grades, and the result as a percentage of the maximum.

An average is the sum of the marks divided by how many there are, and what this calculator adds is the distribution and the percentage beside it. The list "5 4 5 5 3 4 5 4" averages 4.375 from a sum of 35 across eight marks: four fives, three fours and a three.

The percentage of the scale maximum is the useful part when the figure has to travel: 4.375 out of 5 is 87.5 percent, and a percentage is what the grade converter takes.

Marks go into one field, separated by spaces, commas or line breaks — there is no need to retype them one box at a time.

How to use

Paste or type the marks into a single field; any separator works.
Set the scale maximum: 5 for a five-point scale, 4 for a GPA, 100 for percentages.
Read off the average, the sum, the count and the distribution.
Use the percentage of maximum if the mark has to be converted to another scale.

How much one mark moves the average

Every row is a calculator run. The weight of a single mark is inversely proportional to how many there are: in a list of five a low mark costs 0.4, in a list of twenty it costs 0.1.

Calculator runs with a scale maximum of 5.
Marks	Count	Sum	Average	Percentage of 5
5 4 5 5 3 4 5 4	8	35	4.375	87.5%
5 5 4 4 4	5	22	4.4	88%
5 5 5 5 5	5	25	5	100%
5 5 5 5 3	5	23	4.6	92%
4 4 4 4 4	5	20	4	80%

Rounding, and what sits behind it

The calculator reports both the exact average and the rounded one. Whether 4.49 becomes a 4 or a 5 on a transcript is a matter of institutional rules rather than arithmetic: some round in the student's favour, some require the threshold to be strictly exceeded.

So read the exact figure and the distribution together. The distribution answers the question the average cannot: if you are two tenths short, it shows how many low marks would have to be replaced to close the gap.

What this calculator shows

The average to three decimals and the rounded value
How many grades there are, their sum and how they are distributed
The result as a percentage of the maximum grade

What to keep in mind

All grades are treated as equal. Where a test should count for more than homework, use the weighted average instead.
Rounding to a whole number follows the ordinary rule: 4.5 rounds to 5, 4.49 to 4.

FAQs

How do I calculate an average mark?

Add the marks and divide by how many there are. For "5 4 5 5 3 4 5 4" that is 35 ÷ 8 = 4.375.

How do I turn an average into a percentage?

Divide by the scale maximum and multiply by a hundred: 4.375 out of 5 is 87.5 percent. The calculator does it as soon as you set the maximum.

Does 4.5 round up?

That is an institutional rule rather than an arithmetic one. The calculator shows both the exact and the rounded figure; the rounding convention will be in your assessment regulations.

How many top marks does it take to cancel a low one?

It depends on the average you are aiming for. With one 3, three 5s bring the average to 4.5: (3 + 3 × 5) ÷ 4 = 4.5. No number of 5s takes it back to exactly 5. Add the marks you expect to the list and the calculator shows the result.

Can I use this for a 4.0 GPA?

Yes — set the maximum to 4 and enter the grade points. If the courses carry different credit values, use the weighted average calculator or the semester GPA planner instead.

How should the marks be entered?

All in one field, separated by spaces, commas or line breaks — the calculator accepts any of them.

What does the distribution show?

How many marks of each value are in the list. For "5 4 5 5 3 4 5 4" it reads "5: 4, 4: 3, 3: 1" — four fives, three fours and one three.

Worked example

Eight marks over a term

Input: 5 4 5 5 3 4 5 4, scale to 5

Output: average 4.375, sum 35, distribution 5: 4, 4: 3, 3: 1

Note: That is 87.5 percent of the maximum — a B+ and a GPA of 3.3 in this calculator's own conversion table. There is no official conversion, so check the rules of whoever will read the grade.
