Your results
Calculation breakdown
- Percentage
- scored ÷ total × 100
Worked example
Scoring 68 out of 80 marks gives 68 ÷ 80 × 100 = 85%, a High Distinction under common grading conventions.
Assumptions
- Grade band labels are a common Australian convention shown for reference; check your institution's official scale.
How this calculator works
Enter the marks you scored and the total marks available to instantly see your percentage and an indicative grade band such as High Distinction, Distinction, Credit, Pass or Fail.
How to turn exam marks into a percentage
Divide the marks scored by the total marks available and multiply by 100. A result of 68 marks out of 80 is therefore 68 ÷ 80 × 100 = 85%, even when the exam was not marked out of 100.
The calculator accepts decimal marks for partially awarded questions and checks that the score does not exceed the available marks. It shows the exact percentage alongside an indicative Australian university grade band.
- Exam percentage = marks scored ÷ total marks × 100
- Decimal and part marks are supported
- Use the percentage when your institution has its own grade scale
Exam score versus final subject grade
An exam percentage describes performance on that exam only. If the exam is worth part of the subject, multiply the exam percentage by its weighting to find how many points it contributes to the final result.
Use the Weighted Grade Calculator when you have several assessment results, or the Final Grade Needed Calculator when you want to know the mark required on an upcoming exam. Grade labels vary by institution and are shown here only as a guide.
Frequently asked questions
Are the grade bands official?
No — they're common Australian university conventions (85%+ HD, 75%+ D, 65%+ C, 50%+ P) shown for reference only; your institution's bands may differ.
Can I use decimals for marks?
Yes, both the score and total marks accept decimals for part-marked questions.
What happens if marks exceed the total?
The calculator shows an error, since scored marks can't exceed the total marks available.
