Indonesia Grading System Calculator
Calculate your IPK (Indeks Prestasi Kumulatif) using Indonesia's standardized 4.0 GPA scale. Enter letter grades directly or convert from percentage scores with SKS credit weighting.
Use this mode to enter letter grades (A, A-, B+, B, B-, C+, C, D, E) directly with SKS weighting. This matches how final transcripts display grades.
| Main Grading Approach | 4.0 GPA Scale (Numerical/Letter Hybrid) |
| Typical Scale(s) | 0.00 – 4.00 (A, B, C, D, E) |
| Local Credit Term | SKS (Satuan Kredit Semester) — 1 SKS = ~170 minutes/week |
| Credit-Weighted? | Yes. Results are weighted by SKS value. |
| Typical Pass Mark | C (2.0) for core courses; D (1.0) for electives |
| Resits / Retakes | SP (Semester Pendek) or retake in regular semester |
| Rounding Rules | Typically rounded to two decimal places (e.g., 3.45) |
Indonesian universities use a standardized 4.0 GPA scale known as IPK (Indeks Prestasi Kumulatif). The system is standardized across both public (PTN) and private (PTS) institutions under Ministry of Education regulations.
While student work is assessed as percentages (0–100), these marks are converted into letter grades and then to numerical points (0.00–4.00) at the end of each semester.
Assessment Structure: A course grade is typically a weighted composite of:
- Attendance/Assignments: 10–20%
- Mid-terms (UTS): 30–40%
- Final Exams (UAS): 40–50%
Key Definitions:
- IP (Indeks Prestasi): The GPA for a single semester
- IPK (Indeks Prestasi Kumulatif): The cumulative GPA for all semesters
- SKS: 1 SKS is equivalent to roughly 170 minutes of academic activity per week
This hybrid calculator lets you work with either system:
- 4.0 GPA Mode (Letter Grades): Enter letter grades (A, A-, B+, B, B-, C+, C, D, E) directly with SKS weighting. This matches how final transcripts display grades.
- Percentage to GPA Mode: Enter percentage scores (0–100) and see how they convert to letter grades and 4.0 points using the standard conversion table. Useful if you have raw assessment scores.
While specific percentage bands vary slightly by university, the conversion to points is generally consistent across Indonesian institutions:
| Percentage | Letter Grade | Grade Points | Performance (Indonesian) | Performance (English) |
|---|---|---|---|---|
| 85 – 100 | A | 4.00 | Istimewa | Excellent |
| 80 – 84 | A- | 3.70 | Sangat Baik | Very Good |
| 75 – 79 | B+ | 3.30 | Antara Sangat Baik dan Baik | Between Very Good and Good |
| 70 – 74 | B | 3.00 | Baik | Good |
| 65 – 69 | B- | 2.70 | Antara Baik dan Cukup | Between Good and Fair |
| 60 – 64 | C+ | 2.30 | Antara Cukup dan Baik | Between Fair and Good |
| 55 – 59 | C | 2.00 | Cukup | Fair/Pass |
| 40 – 54 | D | 1.00 | Kurang | Marginal Pass |
| 0 – 39 | E | 0.00 | Gagal | Fail |
Your final IPK determines your degree classification and honors:
| IPK Range | Indonesian Term | English Equivalent |
|---|---|---|
| 3.51 – 4.00 | Dengan Pujian | Cum Laude (Honors) |
| 3.01 – 3.50 | Sangat Memuaskan | Very Satisfactory |
| 2.76 – 3.00 | Memuaskan | Satisfactory |
Academic progress in Indonesia is measured by the total number of SKS a student completes. A standard Bachelor's degree (Sarjana) requires 144 SKS. The IPK calculation follows these steps:
- Individual Course Grade: Individual task scores (0–100) are averaged to create a final raw score, which is then mapped to a letter grade using your university's conversion table.
- Assign Grade Points: Convert the letter grade to points (e.g., A = 4.0, B+ = 3.3, C = 2.0).
- Calculate Quality Points: Multiply the Grade Points by the SKS for that course.
- Sum Values: Add all Quality Points and all SKS attempted.
- Divide: IPK = Total Quality Points ÷ Total SKS
Formula: IPK = Σ(Grade Point × SKS) ÷ Σ(SKS)
Special Rules:
- Retakes: When a student retakes a course, most Indonesian universities (like ITB or UGM) will take the highest grade achieved for the IPK, but the original attempt may still appear on the transcript.
- Fail (E): An "E" (0.0 points) means no credits are earned. The student must retake the course if it is a mandatory requirement.
| Course | SKS | Grade | Grade Point | Quality Points |
|---|---|---|---|---|
| Thermodynamics | 4 | B | 3.00 | 12.00 |
| Calculus II | 3 | A- | 3.70 | 11.10 |
| Fluid Mechanics | 3 | C+ | 2.30 | 6.90 |
| English | 2 | A | 4.00 | 8.00 |
| TOTAL | - | - | 38.00 | |
Final IPK = 38.00 ÷ 12 = 3.17 on a 4.0 scale
Classification: Sangat Memuaskan (Very Satisfactory)
- SKS Load: Your IP (Semester GPA) determines how many SKS you can take the next semester. A high IP (≥ 3.0) allows you to take 24 SKS, while a low IP may limit you to 12–15 SKS. This creates a "snowball effect" where failing multiple courses reduces your credit allowance, potentially delaying graduation by a year or more.
- Yudisium: The official university meeting that confirms a student's graduation and final classification based on the IPK.
- Cum Laude Criteria: To graduate Dengan Pujian, many universities require that you have no grades below a C and that you graduate within the standard 4-year timeframe.
| University | Scale Type | Notable Policy |
|---|---|---|
| Univ. of Indonesia (UI) | 4.0 Scale | Uses a highly granular +/- system. |
| ITB (Bandung) | 4.0 Scale | Known for "harsher" percentage-to-letter thresholds. |
| Private Universities | 4.0 Scale | May offer "Semester Pendek" (Short Terms) to fix low grades. |
- To USA: Directly compatible with the US 4.0 scale. A 3.0 in Indonesia is generally seen as a 3.0 in the US.
- To UK: A 3.30+ (B+) is typically considered a 2:1 equivalent. A 3.70+ is a First Class equivalent.
- To Australia: Most Australian universities require an IPK of 2.8 – 3.0 for entry into Master's programs.
