CGPA Calculator: Work Out Your Cumulative GPA
A CGPA calculator combines the results of all your semesters into one number. Instead of averaging GPAs by hand, you enter the GPA and the credits for each semester and the calculator weights them properly, so a heavy semester counts for more than a light one. This free CGPA calculator works on a 4.0, 5.0 or 10-point scale, shows an approximate percentage, and has a second mode for updating your CGPA after a new semester. A target planner shows the GPA you need next, and you can copy the result with one tap.
Quick answer: semesters with GPAs of 3.5, 3.8, 3.2 and 3.6 over 15, 16, 15 and 14 credits give a CGPA of 3.53 on a 4.0 scale, from 211.70 quality points across 60 credits.
How CGPA Is Calculated
Each semester GPA is multiplied by the credits of that semester to get quality points. Add up the quality points, then divide by the total credits.
Worked Example
Here is the first example in full. Notice that the total is divided by credits, not by the number of semesters.
| Semester | GPA | Credits | Quality points |
|---|---|---|---|
| Semester 1 | 3.50 | 15 | 52.50 |
| Semester 2 | 3.80 | 16 | 60.80 |
| Semester 3 | 3.20 | 15 | 48.00 |
| Semester 4 | 3.60 | 14 | 50.40 |
| Total | 60 | 211.70 |
211.70 ÷ 60 = 3.53. A plain average of the four GPAs would give 3.52, which is slightly different because the semester with 16 credits carries more weight.
Updating Your CGPA After a New Semester
Switch to Update CGPA if you already know your CGPA and credits. With a 3.40 CGPA over 60 credits and a new semester GPA of 3.80 over 15 credits, the new CGPA is (3.40 × 60 + 3.80 × 15) ÷ 75 = 3.48. If you add a target of 3.55 and 15 credits next, the calculator also shows the GPA you would need over those credits to reach it, which in this case is about 3.90. When the needed GPA is above the top of your scale, the target cannot be reached in one semester.
CGPA to Percentage
The widely used rule for a 10-point scale is percentage = CGPA × 9.5, and you can change the factor in the calculator if your university uses another one. The table shows how common values convert. Other scales are not covered by one official formula, so the calculator shows the share of the maximum scale as an estimate. Always follow the rule printed by your university when you need an official percentage.
| CGPA (10-point) | Approx. percentage | Typical description |
|---|---|---|
| 10 | 95% | Outstanding |
| 9 | 85.5% | Excellent |
| 8 | 76% | Very good |
| 7 | 66.5% | Good |
| 6 | 57% | Satisfactory |
| 5 | 47.5% | Pass |
What Is a Good CGPA?
It depends on your scale, your course and what you plan to do next. As a rough guide, the table below shows how the share of the maximum scale is usually described. Many scholarships and graduate programs ask for a CGPA of about 3.0 on a 4.0 scale or 7.0 on a 10-point scale, though competitive courses ask for more.
| Share of maximum scale | On a 4.0 scale | Description |
|---|---|---|
| 90% and above | 3.60 to 4.00 | Excellent |
| 80% to 89% | 3.20 to 3.59 | Very good |
| 70% to 79% | 2.80 to 3.19 | Good |
| 60% to 69% | 2.40 to 2.79 | Satisfactory |
| 50% to 59% | 2.00 to 2.39 | Pass |
| Below 50% | Below 2.00 | Below pass |
Tips to Improve Your CGPA
Early semesters have the most room to move your CGPA, because fewer credits are already in the total. Put extra effort into high-credit courses, since they carry more weight, and plan lighter loads when you take on difficult subjects. For one semester at a time, the GPA calculator is a good place to start, and the grade calculator helps you work out what a final exam needs to score. If you convert marks, the percentage calculator is handy.
Limits of This Calculator
The method assumes the semester GPA you enter is already credit-weighted, which is how most universities report it. Rules for repeated courses, transfer credits, pass/fail courses and rounding differ between institutions, so treat the result as an estimate and rely on your official transcript for formal use.
Who Can Use This Calculator?
Undergraduate and graduate students, parents tracking progress, students preparing scholarship or admission applications, and anyone who needs to turn several semester results into one cumulative figure.
