Marks percentage calculator, with CGPA
This free marks percentage calculator adds up marks obtained and marks total across every subject you enter and instantly shows the overall percentage - no report card maths done by hand, no spreadsheet, and nothing to sign up for. Add a row per subject, remove one you do not need, and the total updates as you type.
Underneath it sits a second, smaller tool: a two-way converter between CBSE’s 10-point CGPA and an indicative percentage, using the exact formula CBSE itself has published - CGPA × 9.5. We say plainly where that formula does and does not apply, because a confident wrong number is worse than an honest caveat.
Calculate marks percentage and CGPA
Enter marks by subject
Add a row for every subject. Leave the name blank if you would rather not type it - the total works either way.
Everything above runs on your own device. No mark is sent anywhere, saved, or visible to anyone but you.
Enter marks obtained and a total for at least one subject to see the result.
Calculated as (total obtained ÷ total marks) × 100, rounded to two decimals.
CGPA and percentage - the CBSE indicative formula
CBSE has publicised CGPA × 9.5 = indicative percentage for converting its own 10-point CGPA. It is not a universal rule - ICSE, state boards and individual schools do not all use it, and even CBSE itself calls the result indicative rather than official for every purpose. Check with the school or board before relying on the figure below for anything formal.
Enter a CGPA between 0 and 10.
Enter a percentage between 0 and 100.
What the numbers actually mean
A report card percentage looks like a single fact, but it is really a small piece of arithmetic that is easy to get subtly wrong by hand - especially once a subject has a different total to the rest, or a mark gets transcribed against the wrong maximum. This calculator does exactly one thing well: it sums what you typed, correctly, and shows the working rather than hiding it.
The formula behind the percentage
Add every subject’s marks obtained together. Add every subject’s total marks together. Divide the first by the second, multiply by 100, and round to two decimal places. That is the whole calculation, and it is the same one schools and boards use for an aggregate percentage across subjects with equal weighting. If your school computes a best-of-five percentage, or weights one subject more heavily than another, this tool will not replicate that - it adds exactly what you enter, in the order you enter it, with no subject dropped or weighted differently unless you leave it out yourself.
Where CGPA × 9.5 comes from, and where it stops applying
CBSE introduced its 10-point Cumulative Grade Point Average system some years ago, and alongside it published a simple conversion for anyone who needs an approximate percentage from a CGPA figure: multiply by 9.5. It is genuinely CBSE’s own formula, not something invented for this page, and it is the number you will see quoted almost everywhere. The part that gets lost in most quick answers online is CBSE’s own qualifier - the result is indicative, used for general comparison, not a substitute for an official transcript or a board-issued equivalence certificate where one is specifically required.
It is also strictly a CBSE formula. ICSE does not use a CGPA scale in the same way, state boards mostly report a direct percentage rather than a grade point average, and individual schools sometimes build their own internal grading entirely. If a form or an institution asks specifically for a percentage rather than a CGPA, and the stakes are real - an admission cut-off, a scholarship threshold - treat this conversion as a starting estimate and confirm the exact requirement with that institution.
Why there is no grade-boundary table on this page
A percentage-to-grade table (A1, A2, B1 and so on) is the one thing a tool like this is often expected to show, and it is the one thing we chose to leave out. CBSE’s grading bands have shifted over different years and schemes, and printing a table without being certain it reflects the current scheme would put a specific, checkable wrong answer in front of a parent - worse than simply not providing it. What this calculator computes is what it can compute exactly: an arithmetic total, a percentage, and CBSE’s own published CGPA formula. Nothing here is a guess dressed up as a fact.
What “marks obtained above the total” usually means
This calculator flags rather than blocks a row where marks obtained is higher than the total entered for that subject. Most of the time that flag catches a typo - a total of 25 typed where 250 was meant, say. Occasionally it is genuine: some boards apply moderation or award a small number of bonus marks that push a result above the nominal maximum. Rather than silently rejecting the entry or silently accepting it without comment, the row is marked so you can look at it once and decide, and the total is still computed either way.
Privacy, stated plainly
A report card is not a casual thing to type into a website, and this tool is built with that in mind. There is no server call anywhere in the calculation - every add, divide and round happens in your device’s own browser using ordinary JavaScript, the same way a spreadsheet formula runs on your machine and not on someone else’s server. Nothing is stored between visits, no cookie remembers a subject name, and no analytics event fires when you type a mark. That matches what our privacy policy promises across the whole site, not just here.
Before you rely on the number
- The percentage here is a straight, equal-weighted average - check whether your school or board weights subjects differently.
- CGPA × 9.5 is CBSE's own formula, described as indicative - confirm with the institution if the stakes are real.
- A flagged row (marks above the total, or a blank field) is worth a second look before you note the total down anywhere official.
- Nothing typed here is saved - write the final number down yourself if you need it again later.

Do we need an account to use it?
No. There is nothing to sign up for and nothing to remember a password for. Open the page, type the marks, read the result, and close the tab whenever you are done.
Do the marks I enter get sent to Scholur or stored anywhere?
No. The whole calculation - every addition, the division for the percentage, and the CGPA conversion - runs as arithmetic inside your own browser. Nothing is transmitted to us or to anyone else, nothing is saved, and there is no analytics event recording what was typed. Closing the tab removes every number instantly, exactly as our privacy policy promises.
How is the percentage actually calculated?
Total marks obtained across every subject, divided by the total marks possible across every subject, multiplied by 100, rounded to two decimal places. That is the standard method schools and boards use for an aggregate percentage across subjects - there is no weighting, no dropped subject and no rounding trick applied silently.
Is CGPA × 9.5 the official way to convert CGPA to percentage?
It is CBSE's own published formula for its 10-point CGPA scale, and it is the one most widely used and quoted. But it is CBSE's formula specifically, described by CBSE itself as indicative rather than official for every purpose - ICSE, state boards and many individual schools use different scales or none at all. Where the percentage genuinely matters - a college application, a scholarship, an eligibility cut-off - check the exact requirement with that institution rather than relying on this conversion alone.
Why doesn't the calculator show a grade like A1 or A2?
Because CBSE's grade boundaries have changed over the years and differ by scheme, and we were not willing to print a boundary table we could not currently verify. Publishing a wrong grade next to a correct percentage is worse than leaving the grade out, so this tool sticks to what it can compute exactly: the total, the percentage, and the published CGPA formula.
What happens if I enter marks obtained higher than the total?
The row is flagged so you can check it, but it is still included in the total rather than silently rejected - a small number of boards do occasionally award marks above the stated maximum through moderation, and refusing to count it would be a bigger surprise than showing the flag.
What if I leave the total marks for a subject blank or type 0?
That subject is left out of the total rather than being allowed to break the division. A total of zero cannot be divided by, so the calculator flags it and excludes it, instead of showing a nonsense result like Infinity.
Can I use this for a single subject instead of a full report card?
Yes. Delete the extra rows down to one, or simply leave the others blank - a blank row is ignored completely and does not affect the total.
Does it work on a phone?
Yes. The boxes are sized for a thumb, the number keyboard opens automatically for the mark fields, and it works in any modern browser without installing anything.
Percentage is fine. A subject still isn't.
