CGPA Calculator
Calculate cumulative grade point average across courses and semesters.
Students10.0 total credits · 37.9 grade points
CGPA, cumulative grade point average, is your GPA across everything you have studied so far, not just one term. This calculator totals the grade points and credits from all your courses, whether you enter them term by term or all at once, and divides one by the other. It is the number that appears on transcripts and the one most often asked for on applications and job forms.
How to use the CGPA Calculator
- Add a row for each course across all semesters.
- Select the grade and enter the credits for each course.
- Check the running totals for grade points and credits.
- Read your CGPA on the 4.0 scale.
Formula
Each course contributes grade points x credits, exactly as in a single-semester GPA. The cumulative figure is not the average of your semester GPAs unless every semester carried identical credits.
Worked example
Semester 1: 15 credits at a 3.40 GPA, worth 51.0 grade points. Semester 2: 18 credits at a 3.10 GPA, worth 55.8 grade points. CGPA = (51.0 + 55.8) / 33 = 3.24. Averaging the two GPAs directly would give 3.25, a small but real error caused by the unequal credit loads.
Good to know
The unequal-credit trap is the main reason CGPA exists as its own calculation. A light semester with high grades cannot lift the cumulative figure as much as students expect, and a heavy semester with a dip drags it more. Some universities also publish CGPA on a 10-point scale, common in India, where the approximate percentage is CGPA x 9.5. The GPA to Percentage converter covers the 4.0-scale conversions used in North America.
US grading scale reference
The table below is the US plus/minus scale used across this site. Where this tool offers other scales, the Canadian scale sets an A from 85% with a pass at 50%, and the Australian scale uses the bands HD (85%+), D (75-84%), C (65-74%), P (50-64%) and F (below 50%) on a 7.0 GPA.
| Letter grade | Percentage | GPA points |
|---|---|---|
| A+ | 97–100% | 4.0 |
| A | 93–96% | 4.0 |
| A- | 90–92% | 3.7 |
| B+ | 87–89% | 3.3 |
| B | 83–86% | 3.0 |
| B- | 80–82% | 2.7 |
| C+ | 77–79% | 2.3 |
| C | 73–76% | 2.0 |
| C- | 70–72% | 1.7 |
| D+ | 67–69% | 1.3 |
| D | 63–66% | 1.0 |
| D- | 60–62% | 0.7 |
| F | 0–59% | 0.0 |
Frequently asked questions
What is the difference between GPA and CGPA?
GPA usually refers to a single semester or term. CGPA is cumulative across all completed terms. Both use the same weighted formula; the CGPA simply includes more courses.
Can I calculate CGPA from semester GPAs?
Yes, if you know each semester credit total: multiply each semester GPA by its credits, add the results, and divide by total credits. The Cumulative GPA Calculator is built for exactly that input.
Is a 3.24 CGPA good?
It is above the 3.0 line most employers and programmes use as a first filter, but expectations vary: competitive graduate programmes often look for 3.5 and above.
How do I convert CGPA to a percentage?
On the 4.0 scale, a common approximation is GPA / 4 x 100, though some institutions use a table instead. On the Indian 10-point scale, the standard estimate is CGPA x 9.5.
Do failed and repeated courses count in CGPA?
Policies differ. Many universities replace the grade when a course is repeated, others average both attempts, and some count both. Check your academic regulations for the rule that applies to your transcript.
