Calculate your overall percentage from marks obtained and total marks across a semester's subjects.
This tool computes your overall semester percentage as (marks obtained ÷ total possible marks) × 100 -- enter the sum of marks you scored across all subjects and the sum of the maximum possible marks, and get your percentage instantly.
Enter your total marks obtained and the total possible marks for the semester. Your percentage appears instantly.
The tool takes two totals: the marks you obtained across every subject and the maximum marks available across those same subjects. It divides the first by the second, multiplies by 100, and shows the answer with two decimal places. If the total possible marks is zero, the result is 0.00 percent, because a division by zero is meaningless. The tool does not cap the answer at 100, so if you accidentally enter obtained marks larger than the total, you will see a figure above 100 as a hint that something was mistyped.
Semester % = (sum of marks obtained / sum of maximum marks) x 100
Imagine five subjects. Your hypothetical scores are 78 out of 100, 64 out of 100, 85 out of 100, 45 out of 50, and 38 out of 50. Add the obtained marks: 78 + 64 + 85 + 45 + 38 = 310. Add the maximums: 100 + 100 + 100 + 50 + 50 = 400. Enter 310 and 400, and the tool shows 77.50 percent. Notice that the two 50-mark papers count for less than the 100-mark papers, because this method weights every subject by its total marks, not equally.
There is a second way people sometimes compute a semester score: average each subject's percentage. In this example the subject percentages are 78, 64, 85, 90, and 76, and their plain average is 78.6 percent, slightly different from 77.50. Neither is wrong, but they answer different questions. Your institution's rules decide which one appears on your transcript, so check the official calculation before treating this figure as final. If credits or weightings apply, this simple calculator does not model them.
Use the percentage to see how your overall performance compares with a scholarship cutoff, an admission requirement, or your own target. To turn it into a letter grade, try the Marks to Grade Converter, remembering that grade bands are set by each institution. For a job application or official form, quote the figure printed on your transcript or result sheet rather than a self-computed number, because the official version follows the exact rules of your program.
No -- this is a simple marks-obtained-over-total-possible calculation. If your institution weights subjects by credit hours, use the Weighted Average Calculator instead, entering each subject's percentage and its credit hours as the weight.
No -- the calculation happens entirely in your browser.
The tool does not cap the answer. It usually means the obtained marks were entered larger than the total possible, so recheck both numbers for typing errors.
Two. For example, 310 out of 400 is shown as 77.50 percent. The tool does not round to a whole number.
Not always. This method weights each subject by its maximum marks, while averaging percentages treats every subject equally. Results differ when subjects have different totals.
A total of zero gives 0.00 percent, since dividing by zero has no meaning. Enter the combined maximum marks to get a real percentage.
