Overview: the Swiss grading scale
The most widely used system in Swiss schools runs from 1.0 (lowest) to 6.0 (highest). A mark of 4.0 typically denotes a pass. Individual cantons, vocational programs and universities may apply slight rules or notation differences, but the essentials below apply in most cases.
Grade meaning at a glance
- 6.0 — Excellent: exceptional mastery of subject matter.
- 5.0 — Very good: solid, above-average performance.
- 4.0 — Satisfactory: meets minimum required competencies.
- 1.0–3.9 — Below pass: requires remediation or retake.
How to calculate: simple vs weighted average
Two common approaches are used to combine multiple assessment grades into one final course grade: the simple average and the weighted average. Use the simple average if every component counts equally; use a weighted average when some assessments (for example, final exam) matter more than others.
Simple average (arithmetic mean)
Formula: (g₁ + g₂ + ... + gₙ) / n
Weighted average
If component weights differ, multiply each grade by its weight, sum the results and divide by the total weight:
- Exam A: 5.5 (weight 2)
- Exam B: 4.0 (weight 1)
- Project: 5.0 (weight 3)
Total weight = 6 → Final grade = 30 / 6 = 5.0
Rounding and precision
Rounding rules differ by school. Best practice: keep at least two decimal places during calculations and round only at the final result, matching the institution’s policy (common rounding is to one decimal place).
Conversion table and international mappings
Many students must convert Swiss grades for applications abroad. There is no universal conversion; the table below shows a widely used, illustrative mapping to help you estimate equivalence. Always verify with the receiving institution.
| Swiss grade | Descriptor | Approx. ECTS | Approx. US GPA |
|---|---|---|---|
| 6.0–5.5 | Excellent | A | 4.0 |
| 5.4–4.6 | Very good | B | 3.0–3.7 |
| 4.5–4.0 | Satisfactory | C | 2.0–2.9 |
| <4.0 | Below pass | D/E/F (varies) | <2.0 |
Practical tips for accurate calculations
- Always confirm component weights and rounding rules in the course syllabus.
- Save your raw numbers in a spreadsheet so you can reproduce calculations quickly.
- When converting grades for applications, request the official conversion policy from the destination institution.
- If a retake is offered, check whether the new grade replaces the old one or whether both are averaged.
When to use an online calculator
Online grade tools speed up computation and reduce arithmetic mistakes. For a Swiss-focused, easy-to-use interface try the Grade calculator Switzerland. Use online tools as a convenience — always verify results manually for high-stakes situations.
Dealing with edge cases: core subjects and minimum thresholds
Some programs require minimum grades in specific core subjects or apply rules (for example, the average must be ≥4.0 and no core subject below 3.0). Check your program’s regulations early to know which grades are decisive.
Appeals, corrections and documentation
If you suspect an error:
- Collect assessment rubrics and recorded marks.
- Recalculate the grade showing each step and the weights used.
- Contact your teacher or exam office with the documented computation and politely request clarification.
- If unresolved, follow your institution’s formal appeal process. Keep copies of all correspondence.
Checklists: quick reference
Before calculation
- Confirm grading scale and pass threshold (usually 4.0).
- Gather all grades and their documented weights.
- Note any special rounding or retake rules.
After calculation
- Round the final result according to policy.
- Cross-check with an online calculator or spreadsheet.
- Save the workings and screenshots for records or appeals.

Final thoughts
Understanding how grades are calculated gives you control over planning and revision. Use clear records, verify weights, keep intermediate decimals during computation, and use a reliable tool for a quick sanity check. When converting grades internationally, always defer to the official guidance from the receiving institution.
