The Percentage Formula

The standard formula for converting percentages to Swiss grades (1-6) is:

Grade = 1 + (5 × Percentage)

Important: The percentage must be entered as a decimal (e.g., 0.80 for 80%).

Key Thresholds (Linear)

0% Grade 1.0
20% Grade 2.0
40% Grade 3.0
60% Grade 4.0 (Pass)
80% Grade 5.0 (Good)
100% Grade 6.0 (Excellent)

The 60% Threshold

In a purely linear system, the passing grade (4.0) is at exactly 60% of performance. However, some teachers adjust this scale (e.g., passing already at 55%) to make the exam fairer.

Calculate grade average

Examples from School Life

  • Math test: 18 out of 24 points (75%) → Grade 4.75 (Good)
  • French vocabulary: 31 out of 50 words correct (62%) → Grade 4.0 (Pass)
  • Biology exam: 22 out of 25 points (88%) → Grade 5.5 (Very Good)
  • German essay: 10 out of 20 points (50%) → Grade 3.5 (Fail)

Tip: At many schools, grades are rounded to quarter grades (0.25). Ask your teacher about the rounding method used.

Conclusion

Multiply your percentage by 5 and add 1. That's your grade (before rounding).

Frequently Asked Questions About Percentage Conversion

Why is 60% exactly a 4.0?
In the linear scale, every 20% equals one grade point. 0% = 1, 20% = 2, 40% = 3, 60% = 4, etc. The 4.0 is the passing grade in Switzerland.
What if my teacher uses a different scale?
Some teachers use a 'kink' (e.g., 4.0 at 55%). Ask about the grading scale used if you're unsure.
How do I calculate quickly in my head?
Remember: 60% = 4.0, 80% = 5.0. In between is a linear progression. For every 4% more, you get about 0.2 grade points.
Does this formula apply to the Matura as well?
Matura grading can vary by canton and subject. The linear formula is a good guideline but not always exactly applicable.
