Australian WAM & GPA Calculator
Enter each course with its credit points and mark (and the grade, if you know it). You get your weighted average mark (WAM) and your GPA on the 7-point scale used by many Australian universities.

How to use the Australian WAM & GPA Calculator
- Choose the mark bands your university uses to turn marks into HD, D, C and P — or select each course’s grade yourself.
- Add every course with credit points and its mark and/or grade.
- Read your WAM (0–100) and your 7-point GPA.
WAM versus GPA
WAM (weighted average mark) is the average of your marks, weighted by credit points, and is a number from 0 to 100. GPA on the Australian 7-point scale is the average of grade points weighted the same way:
WAM = Σ (mark × credit points) ÷ Σ credit points
GPA = Σ (grade point × credit points) ÷ Σ credit points
The 7-point values are HD = 7, D = 6, C = 5, P = 4 and fail = 0, as published by universities such as the Australian National University and the University of Canberra. How WAM is defined is explained, for instance, by RMIT.
Worked example
| Course | Credit points | Mark | Grade | Grade point |
|---|---|---|---|---|
| Economics A | 6 | 82 | HD | 7 |
| Mathematics A | 6 | 74 | D | 6 |
| Programming A | 6 | 91 | HD | 7 |
| Accounting A | 6 | 63 | C | 5 |
| Law A | 6 | 55 | P | 4 |
WAM = (82 + 74 + 91 + 63 + 55) ÷ 5 = 73.0 (all courses have 6 credit points). GPA = (7 + 6 + 7 + 5 + 4) ÷ 5 = 5.80, using the bands HD 80+, D 70–79, C 60–69 and P 50–59.
Rules that differ between universities
- Mark bands. The ANU example uses HD 80+, D 70–79, CR 60–69, P 50–59. Some universities use 85/75/65/50 instead — the calculator offers both, or choose each grade yourself.
- Conceded and supplementary passes. University of Canberra’s “PX” counts as 3; at ANU a pass at a supplementary exam (PS) counts as 4.
- Which courses count. Pass/fail, withdrawn, deferred and credit-transfer courses are generally left out. Some universities also weight higher-level units more heavily in their WAM.
Use the calculator for planning and the figure on your official transcript for anything formal. For a general GPA on the 4.0 scale see the GPA calculator.
Frequently asked questions
What is the difference between WAM and GPA?
WAM averages your marks (0–100); GPA averages grade points (HD = 7 … fail = 0) on a 7-point scale. Both are weighted by credit points.
How do I calculate WAM?
Multiply each course’s mark by its credit points, add the results and divide by the total credit points. The calculator does this for every row that has a mark.
What mark is a High Distinction?
Commonly 80 or more, and 85 or more at some universities. Pick the band set that matches your university or select the grade directly.
Does a fail count in GPA?
Usually yes: it is worth 0 grade points and its credit points still count. Choose “F” for the grade, or enter a mark below 50.
Is this my official WAM?
No — the official figure is on your transcript. Universities exclude certain courses or apply different weights, so expect small differences.
