Marks Percentage Calculator
Calculate your percentage from obtained marks and total marks, with an optional target or passing percentage check.
Results
This calculator uses the basic marks percentage formula: obtained marks divided by total marks, multiplied by 100. Official grading may differ if your school uses curves, practical marks, bonus marks, negative marking, or subject-wise minimum requirements.
Use this Marks Percentage Calculator to calculate your percentage from obtained marks and total marks. You can also enter a target or passing percentage to check how your result compares.
Marks Percentage Formulas
Percentage = (obtained marks ÷ total marks) × 100
Marks lost = total marks − obtained marks
When a target percentage is entered:
Target marks = (target percentage ÷ 100) × total marks
Target difference = obtained marks − target marks
Example
Suppose a student scores 420 marks out of 500 and wants to check against a 75% target.
Percentage = (420 ÷ 500) × 100 = 84%
Marks lost = 500 − 420 = 80
Target marks = (75 ÷ 100) × 500 = 375
Target difference = 420 − 375 = 45 marks
The student scored 84% and is 45 marks above the 75% target.
Important Notes
- Obtained marks should not normally exceed the total possible marks unless bonus marks are officially allowed.
- The grade band shown by the calculator is a general interpretation only.
- Schools, universities, examination boards, and individual courses may use different passing marks, grade boundaries, rounding rules, curves, or subject-wise requirements.
- For official results, follow the grading policy provided by your institution or examination authority.
