How to Calculate the Percentage of Marks

The percentage formula is the same everywhere — Matric, FSc, O/A Level or university:

Percentage = (Obtained Marks ÷ Total Marks) × 100

Worked example: a student scores 856 marks out of 1100. Divide 856 by 1100 to get 0.7782, then multiply by 100 — the percentage is 77.82%. This calculator does exactly that, and in subject-wise mode it first adds up all your obtained marks and all your total marks before applying the formula, which is how boards and universities calculate an overall result.

The "marks needed for a target" mode simply reverses the formula: Needed Marks = (Target % ÷ 100) × Total Marks. So for 80% out of 1100 total marks you need 0.80 × 1100 = 880 marks. Whole-mark answers are rounded up, because scoring slightly below the exact figure would leave you under your target.

  • Works for any marking scheme — 75, 100, 550, 1100, 1200 or any other total.
  • Subject-wise mode shows each subject's own percentage, so you can spot your weakest areas at a glance.
  • Everything runs in your browser — your marks are never uploaded or stored.

Percentage Calculator FAQs

Use subject-wise mode: add a row for each subject, enter your obtained and total marks, and the overall percentage is calculated from the combined totals — the same way your board calculates it.
Averaging percentages only gives the correct overall result when every subject has the same total marks. When totals differ (say a 200-mark subject and a 75-mark subject), you must add the marks first and then divide — which is what this calculator does.
Not yet — grade boundaries differ between boards and change over time, so a dedicated Grade Calculator is coming to this Study Tools section soon.
No. The calculation happens entirely in your browser — nothing you type is sent to our server, stored, or shared.
