CGPA Calculator for Peru
Calculate your PPS (semester) or PPA (cumulative) using Peru's vigesimal scale (0–20). Credit-weighted averages as used by PUCP, UNMSM, Universidad de Lima and other SUNEDU-accredited universities.
Peruvian universities use a vigesimal scale (0–20). There is no conversion to quality points like a 4.0 GPA; raw grades are used directly in the weighted average.
- PPS / PPA: Promedio Ponderado Semestral (semester weighted average) and Promedio Ponderado Acumulado (cumulative weighted average).
- Credits: Créditos. Grading is almost universally credit-weighted.
- Pass mark: 11 is the legal minimum. Some institutions (e.g. PUCP, Universidad de Lima) may require 12 or 13 for specific programmes.
- Rounding: 0.5 or higher rounds up to the next integer (e.g. 10.5 → 11 = pass).
- Grades awarded: Each course receives a numerical grade (0–20).
- Credit multiplication: Grade × Credits = points for that course.
- Summation: Sum all points.
- Division: Total points ÷ Total credits.
- PPS vs PPA: PPS uses only the current semester; PPA includes all credits since programme start.
| Peruvian Grade (0–20) | Descriptor | US Approx. |
|---|---|---|
| 18–20 | Sobresaliente (Excellent) | A+ / A |
| 16–17 | Muy Bueno (Very Good) | A− |
| 14–15 | Bueno (Good) | B |
| 12–13 | Regular (Satisfactory) | C |
| 11 | Suficiente (Passing) | D |
| 0–10 | Desaprobado (Fail) | F |
Note: An 18 is exceptionally rare in many faculties (e.g. Engineering, Law).
| Course | Credits | Grade (0–20) | Weighted Points |
|---|---|---|---|
| Cálculo I | 5 | 14 | 70 |
| Antropología | 3 | 17 | 51 |
| Química General | 4 | 12 | 48 |
| Taller de Comunicación | 2 | 18 | 36 |
| Totals | - | 205 | |
Semester Weighted Average = 205 ÷ 14 = 14.64
Final rounded grade: 15 (Bueno)
- Promedio Ponderado Semestral (PPS): Semester average. Used for Dean's List (Quinto Superior) honours.
- Promedio Ponderado Acumulado (PPA): Cumulative average of all courses. Equivalent to CGPA.
- Orden de Mérito (Class Rank): Décimo Superior (top 10%), Quinto Superior (top 20%), Tercio Superior (top 33.3%). Often more important than the numerical average for employers.
Pontificia Universidad Católica del Perú (PUCP)
Scale: 0–20
Weighted average; pass 11. Uses Coeficiente de Rendimiento Académico (CRAEST).
RegulationsUniversidad Nacional Mayor de San Marcos (UNMSM)
Scale: 0–20
Public university standard. Pass 11. Rigorous rounding rules.
RegulationsUniversidad Peruana Cayetano Heredia (UPCH)
Scale: 0–20
Specialized in sciences; high performance required for medical residency ranking.
RegulationsUniversidad Peruana de Ciencias Aplicadas (UPC)
Scale: 0–20
Credit-weighted averages; electronic transcripts include class rank.
Regulations- Non-linearity: Converting a 15 to US 3.0 may under-evaluate. Credential services (WES, ECE) recognize that a 20 is harder to achieve than a US 4.0.
- 11 threshold: While 11 is pass in Peru, US institutions may view 12 or 13 as minimum for transferable credit (≈ C).
- Rank matters: A 14/20 student in Quinto Superior can be more competitive than a 16/20 student in a less rigorous programme, especially for UK/Europe applications.
