Marks Percentage Calculator
Add your subjects, type in the marks you scored and the total marks, and get your overall percentage and grade instantly. Works for any number of subjects.
Calculate Your Exam Percentage in Seconds
This marks percentage calculator takes the marks you scored in each subject and the maximum marks for each, and turns them into one clean overall percentage — plus a CBSE-style grade so you know roughly where you stand. It handles a single subject or your whole report card, and it shows the percentage for each subject too, so you can see exactly which ones pulled your average up or down.
It runs entirely in your browser. Nothing is saved, nothing is uploaded, and there is no signup. Whether you are checking a unit test, a semester result, or a full board exam, the maths is the same and the answer is instant.
The Formula (and Why It Trips People Up)
Percentage of marks is one of the simplest formulas in school, and also one of the most mis-typed into a calculator at 11pm before results day. Here it is:
Percentage = (Total marks obtained ÷ Total maximum marks) × 100
The mistake people make is averaging the per-subject percentages instead of summing the actual marks. If your subjects are all out of the same total, the two give the same answer. If they are out of different totals — say one subject is out of 50 and another out of 100 — averaging the percentages is wrong. This calculator always sums the real marks, so you get the correct figure either way.
CBSE-Style Grade Bands
If your school uses CBSE-style grading, here is roughly how percentage maps to grade. The calculator shows this automatically:
- A1 — 91 to 100%
- A2 — 81 to 90%
- B1 — 71 to 80%
- B2 — 61 to 70%
- C1 — 51 to 60%
- C2 — 41 to 50%
- D — 33 to 40%
Other boards use different cut-offs, so treat the grade as a guide, not gospel. If you need to turn a CGPA into a percentage instead, use the CGPA to Percentage tool, and if you want to know what you still need to pass, try Marks Needed to Pass.
