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.
Three worked scenarios
The same raw score means very different things depending on the pass mark in effect:
| Score | Out of | Your % | Pass mark | Result | Margin |
|---|---|---|---|---|---|
| 56 | 80 | 70% | 50% | PASS | +20 pts |
| 56 | 80 | 70% | 75% | FAIL | −5 pts |
| 33 | 50 | 66% | 60% | PASS | +6 pts |
Notice that the same 56/80 score passes comfortably in a UK university context (40% pass mark) and a standard US class (60–70% threshold), but fails a professional-certification exam requiring 75%.
Pass marks around the world
Pass marks vary significantly by institution and country, which is why the tool lets you enter your own:
- UK universities: undergraduate pass is commonly 40%, with 70% for a first-class mark
- US schools: typical classroom pass is 60–70%
- Professional certifications: often 70–80% (for example, many bar exams and medical licensing exams require 75% or higher)
- Indian universities: many boards use 33% or 35% as the minimum pass
- Secondary education in Europe: many systems use 50% or a score of 5/10
Always confirm the exact threshold with your institution or exam body — the tool is only as accurate as the pass mark you provide.
What the margin tells you
The margin is the distance in percentage points between your result and the pass mark. A positive margin of just 1 point may feel precarious, while a 20-point margin suggests a comfortable buffer. If you are close to the line, the margin also shows precisely how many additional marks you would have needed. For a 200-mark exam, a −2 point margin means you were 4 raw marks short — concrete and actionable for knowing what to focus on next time.
Notes
Grade boundaries and pass marks are set by each institution, so always confirm the official figures before relying on the estimate. The letter grade shown is a general reference based on your percentage and is independent of the pass/fail result.
