Marks and Percentage Calculator

Total the marks you scored, total the marks those papers were out of, divide the first by the second and multiply by 100. Scoring 424 out of 500 is 424 divided by 500, which is 0.848, so 84.8 percent.

The part people get wrong is what to do when subjects are out of different maximums. If one paper is out of 100, another out of 50 and a practical out of 25, you cannot average the three percentages together. Averaging percentages treats the 25-mark practical as equal in importance to the 100-mark paper, which quietly changes your result.

The correct method is to add the marks and add the maximums, which is what this tool does. It is also why every subject is listed separately underneath: the total answers what your percentage is, and the per-subject table answers where it came from.

Sometimes marks alone do not reflect how much a subject counts. A major paper might be worth double a minor one, or a course might set internal assessment at 30 percent of the final result. That is weighting, and it produces a genuinely different number.

Take two subjects, both out of 100. You scored 90 in one and 50 in the other. Added up that is 140 out of 200, a straight 70 percent. Now suppose the weaker subject counts for three times as much. The weighted result is 60 percent, ten points lower, from exactly the same marks.

Neither figure is wrong. They answer different questions. So turn weighting on only if your institution actually applies weights, and use the weights from your own syllabus rather than assuming. When weighting is on, a weight column appears on every row and the tool averages the subject percentages according to it.

Three scales are built in. The CBSE style runs A1 down to E, with A1 at 91 and above. Letter grades run A+ down to F, with A+ at 90 and above. Divisions are the older Indian board convention: distinction at 75, first division at 60, second at 45 and third at 33.

Whichever you pick, the full band table is printed on this page with your band highlighted, and that is deliberate. A grade letter on its own is a claim you cannot check. A grade letter next to the table it came from is one you can verify against your own mark sheet in a few seconds.

One honest caveat. These bands are widely used conventions, not a single national standard, and boards and universities do vary them. Treat the letter as a good indication and your own regulations as the authority.

The pass mark here is applied to each subject on its own rather than to your overall percentage, because that is how most systems work and because the overall figure is the one that hides bad news.

An average of 68 percent sounds settled. If one of those subjects came in at 28 percent against a 33 percent pass mark, the average is not the thing that decides your year. The tool flags every subject below the pass mark in the table and names them in the status line, so it appears whether or not you go looking for it.

This is the same reason the attendance calculator is worth running per subject too. In both cases a healthy average across five subjects can sit on top of one subject that is in trouble.

This is the question that matters most while a term is still running, and it needs two numbers from you: the total marks the remaining papers are worth, and the percentage you want to finish on.

Suppose you are at 224 out of 300 and one paper worth 100 marks is left. To finish on 80 percent you need 80 percent of the final 400 marks, which is 320. You already have 224, so you need 96 out of that last 100. Aiming at 95 percent overall would need 156 marks from a paper worth 100, which is not possible, and the tool states that rather than printing a number that cannot be scored.

Knowing which of those two situations you are in is the entire value of asking early. One is a hard revision plan. The other is a conversation about resits, and it is better to have it in week eight than after the results.

Yes, and for a structural reason rather than a promise. The calculation is done by a small piece of JavaScript that arrives with this page and runs inside your browser. Your marks are never sent anywhere because there is nowhere for them to be sent. No account, no saved history, nothing left behind when you close the tab.

You can test that claim. Load this page, turn off your internet connection, and every part of it keeps working. That only holds if the maths genuinely runs on your own device.

The other tools here work the same local way. If you need to hand something in, text to PDF and JPG to PDF also run entirely in the browser, and everything is listed under all calculators.
