Short answer
CGPA = Σ(semester GPA × semester credits) ÷ Σ semester credits. It weights each semester by the hours you took.
What is the CGPA Calculator?
Cumulative Grade Point Average is a single number summarizing performance across all semesters attempted so far, weighted by the credit hours of each semester.
How does the CGPA Calculator work?
Multiply each semester's GPA by the credit hours attempted that semester to get grade points. Sum grade points across all semesters and divide by total credit hours.
Formula
Variables
GPA_iGrade point average of semester icredits_iCredit hours attempted in semester i
Explanation
Weighting by credits keeps a heavy 18-credit semester from being averaged as equal to a light 9-credit one.
Examples
Example 1: Three semesters: 3.6 (15 cr), 3.4 (16 cr), 3.8 (15 cr)
Points 168.4 ÷ 46 credits ≈ 3.60 CGPA.
Applications
- Degree audits
- Scholarship & honors thresholds
- Grad school applications
Advantages
- Correctly weights heavier semesters
- Comparable across programs on the same scale
Limitations
- Assumes all semesters use the same grading scale (usually 4.0)
Common mistakes
- Averaging semester GPAs directly instead of weighting by credit hours
Tips
- To include a new semester, add it as another row — don't average the new GPA into your old CGPA

Practical use cases and industry applications
Understanding CGPA
Cumulative Grade Point Average is a single number summarizing performance across all semesters attempted so far, weighted by the credit hours of each semester. Within math calculators, cgpa belongs to the academic & grades cluster, where it shares terminology and assumptions with closely related tools.
Learning how cgpa is calculated
Weighting by credits keeps a heavy 18-credit semester from being averaged as equal to a light 9-credit one. Working through the variables one at a time — GPA_i, credits_i — makes the result reproducible by hand and easier to sanity-check.
Using cgpa to make a decision
Degree audits Scholarship & honors thresholds Grad school applications Because outputs depend on the assumptions you enter, run more than one scenario before committing to a figure.
How cgpa compares with related measures
credit hour, weighted mean, grading scale, percentile rank all describe adjacent aspects of academic & grades. Comparing this calculator's output against those measures — using the related tools listed on this page — prevents a single metric from being read in isolation.
Frequently asked questions
Is CGPA the same as GPA?
GPA usually refers to one semester or term; CGPA is the cumulative average across all completed semesters.
How do I convert CGPA to percentage?
There is no universal formula — many Indian universities use percentage = CGPA × 9.5, but confirm with your institution.
