How the WAM Calculator works
This WAM calculator works out your weighted average mark: each unit's mark weighted by its credit points. Type each unit's mark and credit points on its own line and the page returns your WAM, the grade band it sits in and, if you add a target and the credits you have left, the average you need from here. A third number on a line sets a year-level weight for universities whose WAM counts later years more heavily.
WAM calculator: one number that follows your transcript
A weighted average mark is the credit-weighted mean of every unit mark you have. A GPA squeezes a 79 and an 84 into the same grade point; a WAM keeps them apart. That is why Australian universities print it on the transcript and use it to rank students for honours, scholarships, exchange places, dean's lists and university medals. Graduate employers in law, accounting, consulting and banking often screen applications on it before anyone reads a cover letter.
The formula
WAM = Σ(mark × credit points × level weight) ÷ Σ(credit points × level weight).
A 12-credit unit counts twice as much as a 6-credit one. Credit conventions vary, with 6 points at UNSW, Monash and Sydney, 12.5 at Melbourne and 10 at Macquarie, but the units cancel in the division, so type what your transcript shows. The optional third number on a line is the level weight. Leave it out and it is 1. Some universities count first-year units at half weight, or weight later years more, so use your handbook's figure.
To hit a target, the calculator solves for the average needed over the credits you have left: needed = (target × (credits done + credits left) − current weighted sum) ÷ credits left.
Worked examples
The first example is the default four lines: 78, 65, 82 and 71, each worth 6 credits. That is (78 + 65 + 82 + 71) × 6 = 1,776 over 24 credits, a WAM of 74.00. It sits one mark below the Distinction band.
The second example uses year-level weighting. Suppose first-year units carry a weight of 0.5: 24 credits averaging 60, then 24 credits at level two averaging 75 at weight 1. The WAM is (60 × 12
- 75 × 24) ÷ 36 = 70.0, where an unweighted average would give 67.5. Weighting rewards students who improve, and it penalises a weak final year.
How many marks do you need in final year?
The table assumes a three-year, 144-credit degree with 96 credits done and 48 to go. With one third of the degree left, the formula becomes needed = 3 × target − 2 × current WAM, so every mark you are below the target costs two marks of extra effort. Average mark needed over the last 48 of 144 credits to reach each target WAM
| Current WAM | Target 65 | Target 70 | Target 75 | Target 80 |
|---|---|---|---|---|
| 60 | 75 | 90 | Not reachable | Not reachable |
| 61 | 73 | 88 | Not reachable | Not reachable |
| 62 | 71 | 86 | Not reachable | Not reachable |
| 63 | 69 | 84 | 99 | Not reachable |
| 64 | 67 | 82 | 97 | Not reachable |
| 65 | 65 | 80 | 95 | Not reachable |
| 66 | 63 | 78 | 93 | Not reachable |
| 67 | 61 | 76 | 91 | Not reachable |
| 68 | 59 | 74 | 89 | Not reachable |
| 69 | 57 | 72 | 87 | Not reachable |
| 70 | 55 | 70 | 85 | 100 |
| 71 | 53 | 68 | 83 | 98 |
| 72 | 51 | 66 | 81 | 96 |
| 73 | 49 | 64 | 79 | 94 |
| 74 | 47 | 62 | 77 | 92 |
| 75 | 45 | 60 | 75 | 90 |
| 76 | 43 | 58 | 73 | 88 |
| 77 | 41 | 56 | 71 | 86 |
| 78 | 39 | 54 | 69 | 84 |
| 79 | 37 | 52 | 67 | 82 |
The further into a degree you are, the harder a WAM is to move. In the last semester, a 5-mark lift can need 90s in every unit or be out of reach entirely.
How to read the result
- WAM is shown to two decimals, the precision most transcripts use and most cut-offs are applied at.
- Grade band at most universities uses the common scale: High Distinction 85+, Distinction 75–84, Credit 65–74, Pass 50–64, Fail below 50.
- Units counted confirms every line was read. A line that is missing a credit value is skipped.
- Weighted credit points is the divisor. With level weights it will be smaller than your raw credits.
- Average mark needed appears when you enter a target and the credits left. "Not reachable" means over 100. "Already secured" means you would hit the target even with zeros.
The table under the result lists each unit's mark × weight, which shows exactly which units pull the average up or down.
Tips and pitfalls
- Check your university's bands. Melbourne grades on H1 80+, H2A 75–79, H2B 70–74, H3 65–69 and Pass 50–64. A 78 there is H2A, not the Distinction shown here.
- Fails count. Most universities include a fail at the mark received. Some floor it at 44 or 45, and some replace a failed first attempt once it is passed. Enter the figure your rules use.
- Excluded units. Pass/fail units, credit transferred from another institution and cancelled enrolments usually carry no mark and stay out of the WAM. Leave them off the list.
- Honours cut-offs vary. Many faculties set entry between 65 and 75, and some rank rather than use a fixed floor. Check the exact rule for your programme.
The GPA calculator turns the same marks into a 7-point GPA for applications that ask for one. For a single unit, the final grade calculator finds the exam mark you need. School leavers can estimate a ranking with the ATAR estimator.

FAQ
What is the difference between WAM and GPA?
A WAM averages the raw marks, weighted by credit points; a GPA converts each mark to a grade point first and averages those. A WAM of 79 and 84 are distinct; both are a 6 on the 7-point GPA scale. Universities that report WAM generally regard it as the finer measure.
What is a good WAM?
Above 75 is a Distinction average and is the usual floor for honours entry; above 80 is competitive for scholarships and graduate programmes that screen on marks; above 85 is a High Distinction average. What counts as good depends on the faculty and the purpose, so check the specific cut-off you are aiming at.
How do I convert a WAM to a GPA?
There is no exact conversion because the GPA scale is banded. A common rough guide is WAM 85 or above to GPA 7, 75 to 84 to 6, 65 to 74 to 5 and 50 to 64 to 4. Use the GPA calculator with your actual grades for a proper figure.
Do failed units count in the WAM?
At most universities yes, at the mark you received, which is why one fail is expensive. Some universities floor a fail at a set mark such as 44 or 45 for WAM purposes, and some drop the first attempt if the unit is later passed; check your handbook and adjust the lines you enter.
Why does my calculated WAM differ from my transcript?
Usually because of a rule the page does not apply: level weighting you did not enter, a repeated unit counted differently, an excluded unit or a fail floor. Enter the level weights and remove excluded units and the figures should agree to the second decimal.
