Calculator
What the Marks Calculator does
Marks Calculator: calculates Percentage from Marks obtained and Total marks. Example: marks obtained 425 and total marks 500 gives percentage 85.00.
This calculator reads Marks obtained and Total marks and produces Percentage. Adjust anything and the figures re-derive on the spot.
Most people who open the Marks Calculator are anyone converting between marking scales. Knowing where you stand before the final exam changes how you revise.
The page holds your values in memory and forgets them the moment you close it.
Each field is explained further down, along with the method and a worked example that uses the default values.
What do the Marks Calculator fields mean?
The Marks Calculator uses 2 inputs. The page opens in a usable state: real values in, real answer out, ready to edit.
| Field | What to enter | Default |
|---|---|---|
| Marks obtained | accepts 0 to 100000 | 425 |
| Total marks | accepts 1 to 100000 | 500 |
How does the Marks Calculator work?
Each output is derived from the inputs above in a single pass; there is no hidden state carried between runs, so the same inputs always give the same calculation.
Validation runs before the calculation, which is why a mistyped value shows an error rather than a plausible-looking result.
Worked example
These are the values the Marks Calculator loads by default, and the result it produces from them. Below is the same computation the tool performs on load, step by step.
| Marks obtained | 425 |
|---|---|
| Total marks | 500 |
| Percentage | 85.00 |
|---|
How to use it
- Set Marks obtained (0 to 100000).
- Put Total marks (1 to 100000).

- Check Percentage on the right.
- Copy Link when you want to return to this exact configuration; Print when someone needs it on paper.
What this tool does not do
- Grading scales differ between institutions; check your own before relying on a converted figure.
- Grading scales differ between institutions; check your own scale before relying on a converted figure.
- Where a standard has revisions, the version used is the one named in the method section.
- The result inherits any error in the inputs without flagging it.
Frequently asked questions
Marks obtained and Total marks. That is the whole form. Every box already holds a working value, so you can change one value at a time and watch how the result responds.
Marks obtained accepts 0 to 100000. Go outside it and you get an error against that specific field instead of a misleading number.
With the values loaded when the page opens, percentage comes out as 85.00. Adjust any field to see how much the answer depends on it.
