Frequently asked questions

How is marks percentage calculated?

Divide the marks you obtained by the total marks available, then multiply by 100.

Can I use this for a single subject or a whole exam?

Yes. As long as the obtained and total figures are for the same set of marks, the percentage is correct, whether that is one test or a full semester.

What if the total is zero?

A percentage needs a non-zero total. Enter the actual maximum marks available; the calculator cannot divide by zero.

Does this work for weighted components?

This calculator treats the total as one number. If your paper weights sections differently, add up the obtained and total across sections first, then enter those sums.

Is this the same as my grade?

It gives the percentage. Your letter grade depends on your institution's grade boundaries, which the grade calculator can help you map.
