In short
- What it calculates
- Mean, median and pass count from your list of marks.
- Formula used
Average = sum of marks / number of marks- Example
- Marks: 75 · 80 · 62.5 · 90 · 55
Grade average calculator
Paste your marks and get the average instantly, along with how many are above the pass mark.
It works with any scale: 0–10, 0–20 or 0–100; you only need to set the pass mark.
How it works
The average adds all the marks and divides by how many there are. When every subject carries the same weight, this is the figure on your transcript.
If subjects have different credit values, you need a weighted average instead.
Formula
Average = sum of marks / number of marks
Median = middle value of the sorted marks
Worked example
Marks: 75 · 80 · 62.5 · 90 · 55
Sum: 362.5
Average: 362.5 / 5 = 72.5
Median: 75
Passing: 5 of 5 (pass mark 50)
Explanation
The arithmetic mean is not always the fair mark
If every subject carries the same weight, adding up and dividing is enough. But as soon as there are credits, teaching hours or exams worth more than others, the simple mean stops representing the record. That is where the weighted mean comes in, multiplying each mark by its weight before summing.
Be careful converting between scales
A 7 out of 10 is not a 70 out of 100 in terms of difficulty. In France, marked out of 20, a 14 is considered very good and a 16 excellent, whereas 14 out of 20 converted literally would read as a 7. Converting scales linearly ignores how differently marks are distributed between systems.
Dropping the lowest mark
Many programmes allow the worst result to be discarded. The effect is not proportional: the fewer marks there are, the more the average rises when one is removed. With four marks, dropping the worst can move the average by almost a whole point.
Rounding counts too
A 6.95 may appear as 7 or as 6.9 depending on the institution's rules. In records that give access to scholarships or limited places, that difference decides. Check whether the regulations round, truncate or keep the decimals.
Frequently asked questions
Does a 3-credit subject count the same as a 9-credit one?
In this calculator, yes. If credits matter, use the weighted average calculator.
Can I use marks out of 20 or 100?
Yes. The average works the same way; just set the pass mark for your scale.
Can I convert my mark to another education system?
Linear conversion is indicative only: scales have different distributions. For an official process, request the equivalence table from the body assessing your record.
How much does dropping the lowest mark raise the average?
It depends how many marks you have: with few subjects the effect is large, and it shrinks as the number of grades increases.
