Turn marks into a percentage, e.g. 17 out of 25 = 68%, and see an indicative High Distinction, Distinction, Credit, Pass or Fail band.
Your results
Calculation breakdown
- Percentage
- scored ÷ total × 100
Worked example
42 marks out of 60 total is 42 ÷ 60 × 100 = 70%, a Credit under the indicative bands used by this calculator.
Assumptions
- Letter grade cut-offs are a common convention only — always check your school or university's official scale.
How this calculator works
Divide the marks you received by the total marks available to get a percentage, plus a commonly used Australian letter grade equivalent from Fail to High Distinction.
How to convert marks into a percentage
Divide the marks you received by the total marks available, then multiply the result by 100. For example, 42 marks out of 60 is 42 ÷ 60 × 100 = 70%.
The calculator performs that conversion instantly and also shows an indicative Australian grade band. Grade cut-offs vary between schools, universities, courses and assessment policies, so the percentage is the authoritative mathematical result and the band is a guide only.
- Percentage = marks scored ÷ total marks × 100
- Decimal and half-mark scores are supported
- The result is rounded to one decimal place
Australian school and university grade bands
Australian schools do not use one national percentage-to-letter-grade scale: cut-offs can differ by state, school, year level and subject. Universities commonly use labels such as High Distinction, Distinction, Credit, Pass and Fail, but their thresholds also vary.
Use the percentage as the exact calculation, then compare it with the grading table supplied by your school, university or course. The grade band shown by CalcAussie is an indicative higher-education guide, not an official result.

Frequently asked questions
Can I use this for an exam score?
Yes. Enter the marks you scored and the total marks available. The same calculation also works for assignments, quizzes and overall subject totals.
Can total marks be zero?
No, the calculator needs a positive total to work out a percentage and will show an error otherwise.
Are the letter grade cut-offs standard nationally?
No — they're a common convention only. Always check your school or university's official grading scale.
