How Grade Percentage Calculator works

Calculate marks percentage for one or multiple subjects from total obtained and possible marks.

The formula

Overall percentage = total marks obtained ÷ total possible marks × 100.

A practical example

425 marks out of 500 equals 85%.

Important limitations

No letter grade is assigned because grading scales differ by school, course and region.

Frequently asked questions

Are subjects averaged equally?

No. Totals are combined, so subjects with more possible marks carry proportionate weight.

Can obtained marks exceed total marks?

No. Each row is validated against its possible total.
