Poly GPA Calculator
Free GPA calculator for all Singapore polytechnic students. Project your cumulative GPA on the 4.0 scale and plan your university admission targets.
Use the SP / NP / TP (4.0) option for the shared core grade table. For extra grades and school-specific rules, open your polytechnic's calculator. This general tool does not automatically apply school-specific exclusions or repeat-module policies.

Singapore Polytechnic Grading System
All five Singapore polytechnics use a 4.0-point GPA scale. Your cumulative GPA is a credit-weighted average of the modules included in your school's GPA calculation, not an average of semester GPAs. Use the credit units on your results slip. A failed module may still count even though it earns no grade points; exemptions, pass/fail grades and repeats need your school's rules. GPA is one part of university admissions.
The core grades carry the same points at SP, NP, TP, NYP and RP: A earns 4.0 points, B+ earns 3.5, B earns 3.0, C+ earns 2.5, C earns 2.0, D+ earns 1.5, D earns 1.0, and F earns 0. Each polytechnic adds a few grades of its own, such as SP's D- (0.5) and TP's P (1.0), so choose your school below for its exact table.
Polytechnic Grade Points
| Grade | Grade Point | Typical Range |
|---|---|---|
| A | 4.00 | 80-100% |
| B+ | 3.50 | 75-79% |
| B | 3.00 | 70-74% |
| C+ | 2.50 | 65-69% |
| C | 2.00 | 60-64% |
| D+ | 1.50 | 55-59% |
| D | 1.00 | 50-54% |
| F | 0.00 | Below 50% |
Semester GPA and cumulative GPA: an SP example
SP's published example starts with 60 grade-point units over 20 credit units: cGPA 3.00. Its next semester has these five modules. To reproduce it, enter Current CGPA 3.00 and Credits Done 20, then replace the calculator’s example rows with these grades and credits.
| Grade | Credit units | Points × units |
|---|---|---|
| D (1.0) | 5 | 5 |
| C (2.0) | 4 | 8 |
| C+ (2.5) | 2 | 5 |
| B (3.0) | 4 | 12 |
| F (0.0) | 4 | 0 |
This semester only: 1.58
30 grade-point units ÷ 19 credit units = 1.58, shown to two decimal places. Clear both previous-record fields to see this semester alone.
Combined record: 2.31
(3.00 × 20 + 30) ÷ (20 + 19) = 90 ÷ 39 ≈ 2.31. Averaging 3.00 and 1.58 would ignore the unequal credit totals.
Do not enter modules already included in your previous GPA and credits a second time. Use unrounded points from your transcript for the most exact figure.
SP includes examined failed modules and may automatically exclude up to two electives from the final cGPA, from AY2024/25, only when the exclusions improve that final result. Those are SP rules, not blanket instructions for all five polys. Check the SP GPA calculator and inclusion notes or your own school's page before removing a module.
