WAM Calculator
Calculate your weighted average mark (WAM) from unit marks and credit points, as used by Australian universities.
About the WAM Calculator
List each unit on its own line with its mark out of 100 and its credit points, for example “78, 6”. The calculator gives your WAM, the grade band it falls in and the credit points counted.
WAM averages your marks weighted by credit points, so a 12-point unit counts twice as much as a 6-point one. Grade bands are typically HD 85+, D 75–84, CR 65–74 and P 50–64; some universities apply year-level weights.
The formula
WAM = Σ (mark × credit points) ÷ Σ credit points
Worked example
78 (6 points), 85 (6), 64 (12), 91 (6)
- Weighted: 468 + 510 + 768 + 546 = 2,292
- Credit points: 30
- WAM = 2,292 ÷ 30 = 76.4, in the Distinction range
Questions people ask
Is WAM the same as GPA?
No, GPA uses grade points (e.g. 7 or 4 scale); WAM uses percentage marks.
Do fails count?
Usually yes in WAM, unless your university excludes them.
Why did one low mark pull my WAM down so much?
It was probably a double-weighted unit: 12 credit points count twice as much as 6.
