Your Results
Your result is calculated from the entered marks.
Calculate Multiple Subjects
Add subjects to calculate your total percentage across multiple exams. Each subject contributes according to its maximum marks.
| Subject | Marks Obtained | Maximum Marks | Percentage | Grade | Remove |
|---|---|---|---|---|---|
| 85.00% | B | ||||
| 90.00% | A | ||||
| 80.00% | C |
This is a marks-weighted total: a subject with a higher maximum mark contributes more to the combined result. For credit-weighted GPA, use the credit weighting rules of your institution.
Customize Grade Boundaries
Adjust the minimum percentage for each grade to match your school, college, or university’s grading policy.
| Grade | Minimum Percentage |
|---|---|
| A | |
| B | |
| C | |
| D | |
| F |
These are editable example boundaries, not a universal grading standard. Check the official grade thresholds published by your institution.
How Your Grade Is Calculated
Percentage = (Marks Obtained ÷ Total Possible Marks) × 100
Example: (425 ÷ 500) × 100 = 85%
Frequently Asked Questions
How do I calculate my grade percentage?
Divide the marks you earned by the total possible marks, then multiply by 100. For example, 425 out of 500 is 85%.
How do I calculate my letter grade?
Convert your percentage using the grade boundaries set by your school or institution. Grade cutoffs can differ, so use your official grading scale.
How do I calculate the percentage of multiple subjects?
Add the marks earned across subjects, add the maximum marks across those subjects, and divide the total earned marks by the total possible marks. Multiply by 100.
How many marks do I need to reach a target percentage?
Calculate the target marks for the total assessment, then subtract the marks you have already earned. The result is the number of marks still required.
Can I calculate a grade if the maximum marks are zero?
No. A percentage cannot be calculated when the total possible marks are zero. Enter a valid maximum score to get a result.
Are letter grades the same in every country?
No. Schools and universities use different percentage ranges, letter grades, GPA systems, and grading policies. Customize the boundaries to match your institution.
Can I use this tool for weighted subjects?
The multiple-subject section weights each subject by its maximum marks. If your institution uses course credits or other weighting rules, follow those official rules when calculating the final result.
Does this calculator convert percentage to GPA?
This tool focuses on marks, percentages, and letter grades. GPA conversion depends on the institution’s grading policy, so there is no single universal conversion.
Disclaimer: This tool provides an estimate based on the values and grade boundaries entered. It does not replace official results or your institution’s grading policy.
