How this tool works

Percentage = earned marks ÷ available marks × 100. Both values refer to the same assessment or group of assessments.

A quick example

420 marks out of 500 equals 84%.

What to keep in mind

Percentage is not a GPA conversion. Use your institution’s published rules for equivalence.
