GPA & CGPA Calculator
Calculate GPA from grades and credits, and convert CGPA to percentage or percentage to CGPA (10-point and 4-point scales).
About the GPA & CGPA Calculator
This GPA calculator works out your Grade Point Average on the standard 4.0 scale from your course grades and credit hours. Add a row for each course, pick the letter grade (A through F, including plus and minus grades), enter the credits, and your weighted GPA updates live. Add or remove courses freely — a full semester takes under a minute.
GPA is a credit-weighted average: each grade converts to grade points (A = 4.0, B = 3.0, C = 2.0 and so on), each course's points are multiplied by its credits, and the total is divided by total credits. That means a 4-credit A lifts your GPA more than a 1-credit A — exactly how universities compute it.
The second section converts between CGPA and percentage in both directions. For the 10-point scale used by CBSE and most Indian universities, percentage = CGPA × 9.5; for the 4-point scale common in the US, percentage = CGPA ÷ 4 × 100. Students use it for job applications, higher-study forms and comparing marks across grading systems.

Frequently Asked Questions
How is GPA calculated from grades and credits?
Each letter grade maps to grade points (A = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, down to F = 0). Multiply each course's grade points by its credit hours, add these up, and divide by the total credits. A 3-credit A and a 1-credit C gives (12 + 2) ÷ 4 = 3.5.
Is 9.5 the right multiplier for CGPA to percentage?
For the CBSE 10-point scale, yes — CBSE officially prescribed percentage = CGPA × 9.5, derived from the average marks of top performers. Many Indian universities adopt the same factor, but some (like VTU, Mumbai University or AKTU) use their own formulas, so check your institution's official conversion rule before quoting a percentage.
What is the difference between GPA and CGPA?
GPA usually refers to a single semester or term's grade point average, while CGPA (Cumulative GPA) averages all semesters completed so far, weighted by credits. Both use the same calculation method; CGPA simply pools every course you have taken across the programme.
How do I convert a 4-point GPA to percentage?
The common approximation is percentage = GPA ÷ 4 × 100, so a 3.2 GPA is about 80%. This is a linear estimate — actual equivalence varies by institution because grading distributions differ. For official purposes such as visa or admission paperwork, use the conversion certificate issued by your university.
What GPA is considered good?
On the 4.0 scale, 3.0–3.5 is generally solid, 3.5–3.7 is strong, and above 3.7 is excellent (often Dean's List territory). On the Indian 10-point scale, a CGPA of 8+ (roughly 76%+) is usually considered good, and 9+ is excellent. Standards vary by field and institution.
