Weighted grade calculator

Calculate your average on completed assessments and their contribution to the final course grade.

How privacy works

How it works

Enter completed assessments with earned marks, maximum marks and their weights in the final course. Calculate the average on entered work, inspect contributions and export a breakdown or editable backup.

Supported formats

Up to 50 assessments; course weights totaling at most 100%; CSV, PDF and JSON exports. Marks and weights support up to six decimal places.

Good to know

Unlisted work is not treated as zero. An average on partial coursework is not a final course result. No extra credit, curves, dropped scores or school-specific rounding rules are modeled.

Worked example

Before

80/100 at 40% course weight; 90/100 at 60%

After

Final weighted result: 86%; contributions are 32 and 54 percentage points

With only the first assessment entered, the average on entered work is 80% and its contribution to the final course is 32 percentage points.

Average and contribution answer different questions

The entered-work average divides earned contribution by the entered weight. The final-course contribution uses the full course denominator. Use grade target calculator separately to work out what is needed on future assessments.

Troubleshooting

Why is my entered-work average higher than my course contribution?

Only part of the course may be entered. An 80% score on work worth 40% contributes 32 points toward a 100-point final course total.

Common questions

Can weights total more than 100% for extra credit?

No. This tool uses final-course percentages totaling no more than 100%. Check the institution’s own rules for extra credit and curves.

Can I use this without an internet connection?

Yes, after you prepare this tool from Offline help and the browser retains its assets. Installation is optional. All processing dependencies are bundled locally.
