Calculation breakdown
- Weighted grade
- Σ(score × weighting) ÷ Σ(weighting)
Worked example
Assignments weighted 20%, 30% and 50% score 80%, 70% and 60% respectively: (80×20 + 70×30 + 60×50) ÷ 100 = 68%.
Assumptions
- Grade bands shown are common Australian university conventions only, not official cut-offs.
- Assumes weightings entered reflect your subject's actual assessment structure.
How this calculator works
Add up to five assessment components with their scores and weightings to calculate your overall weighted mark for a subject. Useful for checking your running total before final exams.
How a weighted grade is calculated
Each assessment score is multiplied by its weighting. The weighted contributions are added together, then divided by the total weighting entered. This prevents a small quiz from counting as much as a major exam.
For example, scores of 80%, 70% and 60% with weightings of 20%, 30% and 50% produce (80×20 + 70×30 + 60×50) ÷ 100 = 68% overall.
- Use the score achieved on each assessment
- Enter the percentage weighting from the subject outline
- Check the combined weighting before relying on the result
What if the weightings do not total 100%?
If you enter only completed assessments, the calculator normalises the result across the weightings entered. That shows your weighted average on completed work, not the final subject mark.
For a final course grade, include every assessment and make sure the weightings total 100%. If some work is still outstanding, use the Final Grade Needed Calculator to estimate the score required on the remaining weighting.
Frequently asked questions
Do the weightings need to add to 100%?
Ideally yes, but the calculator will still compute a result using the weightings you enter and shows a note if they don't total 100%.
Can I use this for university and school subjects?
Yes, it works for any assessment structure as long as you know each component's percentage weighting and your score.
What if I haven't sat an assessment yet?
Leave its score at 0 to see your current position, or use the Final Grade Needed calculator to work out what you need on remaining assessments.
