How is my percentage calculated?

Your percentage is your raw score divided by the total marks, multiplied by 100. For example, 63 out of 90 is 70 percent. The tool then compares that figure against the pass mark you entered.

What is a typical pass mark?

Pass marks vary by institution and subject. UK universities often use 40 percent, US schools commonly use 60 to 70 percent, and professional exams can require 70 percent or higher. Always use your own institution's official figure.

What does the margin mean?

The margin is the gap in percentage points between your result and the pass mark. A positive margin means you cleared the threshold by that much, and a negative margin shows how far short you fell.

How is the letter grade decided?

The letter grade uses a common A to F scale based purely on your percentage, independent of the pass mark. It is shown for context only, since grade boundaries differ between schools.

Does this work for any grading system?

Yes. Because the tool works from percentages, it adapts to any total marks and any pass mark you enter, whether your exam is out of 20, 100, or 750.

Know instantly whether you passed

Whether an exam is out of 50 or 750, the only thing that decides a pass is your percentage against the institution’s threshold. This calculator converts your raw score into a percentage, compares it to the pass mark you set, and tells you immediately whether you cleared it and by how much. It also estimates an equivalent letter grade so you can see where your result sits on a standard scale.

How it works

Your percentage is simply your raw score divided by the total marks, multiplied by 100. The tool then subtracts the pass mark percentage from your percentage to find the margin. A non-negative margin is a pass; a negative margin is a fail. The letter grade is assigned from your percentage using a conventional banding: 90 and above is an A, 80 to 89 a B, 70 to 79 a C, 60 to 69 a D, and below 60 an F.

Example and notes

If you scored 56 out of 80, your percentage is 70. Against a 50 percent pass mark you pass with a 20-point margin and earn a C on the letter scale. Against a 75 percent pass mark you fail by 5 points. Remember that grade boundaries and pass marks are set by each institution, so always confirm the official figures before relying on the estimate.
