NUS GPA Calculator
The NUS GPA Calculator works out your semester GPA and CGPA at the National University of Singapore, where A+ earns 5.00 and B+ earns 4.00. GPA is each grade point times its Units, added up and divided by total Units.

Calculate NUS GPA before and after S/U
Enter course Units, not the number of courses. Leave Current CGPA and Units Done blank for a semester-only GPA. For a cumulative projection, Units Done means the Units counted in your existing GPA, not all Units earned towards graduation. Omit S/U and CS/CU courses and their Units; a letter-graded F counts as zero.
Try five 4-Unit courses
| Grade | Units | Grade point × Units |
|---|---|---|
| A− | 8 (two courses) | 4.5 × 8 = 36 |
| B | 8 (two courses) | 3.5 × 8 = 28 |
| B+ | 4 (one course) | 4.0 × 4 = 16 |
Edit the four rows to A−, A−, B and B, each with 4 Units. Add one B+ course with 4 Units. The five courses contribute 80 weighted points over 20 Units, giving 4.00. If one 4-Unit B is eligible and you exercise S/U, remove that row: (80 − 3.5 × 4) ÷ (20 − 4) = 4.125, displayed here as 4.13. The remaining 16 Units give the GPA; the S course can still earn 4 Units towards graduation.
A what-if result is not S/U eligibility
Removing a grade below the original average raises that average; removing an equal grade leaves it unchanged, and removing a higher grade lowers it. To take a counted course out of a prior CGPA, recalculate that record first. Use unrounded points from your transcript for the most exact figure.
For courses completed from AY2021/22, D or above becomes S; below D becomes U. Neither contributes to GPA, but only S earns degree Units. The general allowance is up to 32 Units, with intake, advanced placement and prior university experience exceptions. From the AY2025/26 intake, the 20 time-limited Units may be used on courses completed in the first two years. Check your faculty, eligible course, allowance and declaration deadline before deciding; declarations become final after the exercise closes.
Units, exclusions and S/U scope checked 8 October 2026 against NUS grading rules and NUS S/U rules. To plan grades still to come, use the target GPA calculator; it also needs GPA-counted Units.
About the NUS GPA System
NUS uses a 5.00-point Grade Point Average (GPA), called Cumulative Average Point (CAP) until August 2023. As Singapore's oldest and largest university, NUS offers a Satisfactory/Unsatisfactory (S/U) option: the general allowance is up to 32 Units of S/U, with advanced placement and prior-study exceptions, used mainly on first-year courses (courses from the first two years for students admitted from AY2025/2026), and S/U grades do not count toward the GPA. This flexibility is designed to ease the transition into university-level study.
Why GPA Matters at NUS
Your GPA directly determines your honours classification at graduation, with Honours (Highest Distinction) requiring a GPA of 4.50 or above.

NUS Grading Note
NUS grades undergraduate courses on a 5.00-point Grade Point Average (GPA). From 1 August 2023 NUS renamed Cumulative Average Point (CAP) to GPA, modules to courses and Modular Credits (MCs) to Units; the calculation did not change.
What Counts in Your NUS GPA
Use this for letter-graded courses. Grades such as S/U and CS/CU carry no grade point, and Law, Dentistry and Medicine have their own grading.
GPA Tips for NUS Students
- Use the S/U option strategically to protect your GPA. It works on Level 1000 courses and on Level 2000 courses without NUS prerequisites, but not on Level 3000 courses and above.
- Track your GPA after each semester and simulate future scenarios before you choose next semester's courses.
- If you are targeting Honours (Highest Distinction), plan your heavier workload semesters early while S/U is still available as a safety net.
Common GPA Mistakes at NUS
The most common mistake is including S/U-declared courses when calculating GPA by hand. Courses graded S or U are not computed towards the GPA. Only letter-graded courses count, and a failed course stays in the GPA even after you retake it.
NUS Grading System
National University of Singapore uses a 5.0-point grading scale. The highest achievable GPA is 5.0, and letter grades are converted to grade points using the official NUS grade table below. NUS awards degree classifications based on cumulative GPA thresholds, with Honours (Highest Distinction) requiring a CGPA of 4.50 or above.
Each module grade earns a specific number of grade points, which are then weighted by credit units to compute your semester GPA and cumulative GPA (CGPA). Use the NUS GPA calculator above to project your CGPA based on expected grades.
