What is the difference between GPA and WAM?

GPA (Grade Point Average) converts percentage marks to grade points on a 7-point scale and weights by credit points. WAM (Weighted Average Mark) uses the actual percentage marks weighted by credit points. Both measure academic performance but produce different numbers. A student with a 70% average in all subjects has a WAM of 70 and an approximate GPA of 5.0 (Credit). Many Australian universities report both.

Does every fail in a subject affect my GPA permanently?

Yes -- all subjects attempted that appear on your academic transcript contribute to your GPA calculation unless your institution has a specific grade replacement or exclusion policy. Repeating a subject typically adds the new grade as an additional entry rather than replacing the old one. Check your institution's academic regulations for the specific policy.

My university uses a different grade scale -- how do I convert?

Some Australian universities use a 4-point scale (HD=4, D=3, C=2, P=1) or different thresholds. The calculator uses the most common 7-point scale. If your institution uses a different scale, enter your grade points according to your own institution's scale and ignore the grade labels shown in the calculator's dropdown.

Semester results are in and a student is asking whether their average is enough to qualify for an Honours program, a scholarship cut-off, or a GPA-gated elective. You need the weighted GPA before they leave the room.

GPA scale

GPA = Σ(Grade × Credit Points) ÷ Σ(Credit Points) Australian 7-point scale: HD=7, D=6, C=5, P=4, P-=3, F=1. A GPA of 5.0 is Credit average; 6.0 is Distinction average.
US 4.0 scale: A=4.0, B=3.0, C=2.0, D=1.0, F=0. Most US scholarships require a 3.0 minimum.

1 What this calculator does

Calculates Grade Point Average on the Australian 7-point scale and converts to the US 4.0 scale. Weights each subject by credit points so that higher-credit courses contribute more to the GPA than minor subjects. Supports up to 8 subjects.

2 Formula & professional reasoning

AU GPA (7-point) = Sum of (Grade point x Credit points) / Total credit points
Grade points: HD=7, D=6, C=5, P=4, P-=3, F=1
US 4.0 conversion: AU 6.5+ = 4.0 | AU 5.5-6.4 = 3.7 | AU 4.5-5.4 = 3.0 | AU 3.5-4.4 = 2.0

Credit-point weighting ensures that a 12-unit core subject has proportionally more impact on the GPA than a 3-unit elective. This mirrors how universities calculate academic standing. The AU 7-point scale (used by most Australian universities) is converted to the US 4.0 GPA using an approximate concordance -- useful for international scholarship applications and graduate school admissions where a US-format GPA is required.

3 Worked examples

⚠️ Illustrative example only — not clinical or professional instruction.

Basic

Three-subject semester

Given: Subject 1: Distinction (6) x 6 cp | Subject 2: Credit (5) x 6 cp | Subject 3: High Distinction (7) x 6 cp

Working: Weighted sum: (6x6)+(5x6)+(7x6) = 36+30+42 = 108 | Total cp: 18 | GPA: 108/18

Answer: AU GPA: 6.0 / 7.0 (Distinction average) | US equivalent: 3.7 / 4.0

💡 All three subjects have equal credit points so the GPA is simply the average of the grade points: (6+5+7)/3 = 6.0.

Standard

Mixed credit points -- core and elective

Given: Major (12cp): Credit (5) | Core (6cp): Distinction (6) | Elective (3cp): High Distinction (7)

Working: Sum: (5x12)+(6x6)+(7x3) = 60+36+21 = 117 | Total cp: 21 | GPA: 117/21

Answer: AU GPA: 5.57 / 7.0 (Credit average) | US: 3.0 / 4.0

💡 The 12cp major at Credit (5) pulls the average down even though the student earned an HD in their elective. Higher-credit subjects carry more weight -- this is why a weak result in a core subject is hard to compensate with electives.

Advanced

Honours eligibility check -- needs 5.5 AU GPA

Given: 5 subjects: D(6)x6 | D(6)x6 | C(5)x6 | C(5)x6 | P(4)x6

Working: Sum: (6x6)+(6x6)+(5x6)+(5x6)+(4x6) = 36+36+30+30+24 = 156 | cp: 30 | GPA: 156/30 = 5.2

Answer: AU GPA: 5.2 / 7.0 -- below 5.5 Honours cut-off

💡 The student needs to raise their GPA. If they earn HD (7) in a 6cp subject next semester: (156+42)/(30+6) = 198/36 = 5.5 -- exactly meeting the threshold.

4 Sanity check

Australian 7-point grade scale

HD=7 (85%+) | D=6 (75-84%) | C=5 (65-74%) | P=4 (50-64%) | P-=3 (45-49%) | F=1 (<50%)

Some institutions use a 4-point scale (4=HD, 3=D, 2=C, 1=P, 0=F) -- confirm the scale used by your institution.

Common GPA thresholds in AU

Honours entry: typically 5.0-5.5 | Distinction average: 6.0 | WAM equivalent: multiply GPA by appropriate factor

Different universities use different formulas -- GPA and WAM (Weighted Average Mark) are related but not identical.

US 4.0 conversion note

The US GPA conversion is approximate -- there is no single official concordance

For graduate school applications, always check the specific institution's AU-to-US GPA conversion table.

5 Common errors

Error	Cause	Consequence	Fix
Entering percentage marks instead of grade point values	Confusing the raw mark with the grade point	GPA wildly wrong -- percentages of 75 instead of grade point 6	Enter the grade point (7, 6, 5, 4, 3 or 1) not the percentage mark. Convert your grade letter to a grade point using the scale shown.
Using equal credit points for all subjects regardless of unit value	Not checking credit point value for each subject	GPA incorrectly calculated -- minor subjects over-weighted	Check each subject's credit point value on your academic transcript or subject handbook. Use the actual credit point value, not a generic number.
Expecting exact US GPA equivalence for graduate school applications	Treating the conversion as official	Applying to programs with incorrect GPA representation	The US 4.0 conversion is an approximation. Many Australian graduate school applicants use the raw AU GPA and a conversion explanation. Check each institution's preferred format.
Including a grade of 0 for a Fail instead of 1	Treating F as zero points	GPA understated -- most AU universities assign 1 point to a Fail, not 0	The AU 7-point scale assigns 1 grade point to a Fail (F). A Withdraw Fail (WF) typically counts as 0 -- check your institution's grading policy.
