CGPA Calculator USA — Standard 4.0 GPA Scale
US universities use the 4.0 GPA scale with credit-hour weighting. Enter each term's GPA and credits to compute your cumulative GPA.
How this works
USA uses the 4.0 scale. Add each semester's GPA and credits above; we credit-weight them to produce your cumulative GPA and an approximate percentage using the local conversion rule.
Formula
GPA = Σ(Term GPA × Credit Hours) ÷ Σ(Credit Hours). Percentage ≈ GPA × 25.
Example
(3.6×15) + (3.8×15) = 111.0. Total credits = 30. GPA = 111.0 ÷ 30 = 3.70. Percentage ≈ 92.5%.
Notes
- A+ / A = 4.0, A- = 3.7, B+ = 3.3, and so on down to F = 0 (see the /gpa/scale reference chart).
- Weighted GPAs (Honors, AP) can extend the scale to 5.0 in high school.
- Graduate schools typically expect a 3.0 or higher cumulative GPA for admission.
Terminology
- SGPA
- Semester GPA — the same idea as GPA, using the semester-based terminology common in India / AICTE universities.
- CGPA
- Cumulative GPA — a credit-weighted average of every semester you've completed.
- GPA
- Grade Point Average for a single term, computed from letter grades and credit hours.
Grading policies differ by university, department, and academic year. Use your institution's official calculator or transcript office for anything that counts (transfer credit, scholarships, honors).

Yes — US institutions typically call the cumulative average simply GPA, but the calculation is the same as CGPA elsewhere.
What is a good GPA in the USA?
3.5+ is considered strong; 3.0 is the common graduate school minimum; 2.0 is usually needed to remain in good academic standing.
How do universities in the USA calculate CGPA?
CGPA is the credit-hour weighted average of your semester GPAs. Multiply each semester's GPA by its credits, sum them, and divide by total credits.
Is this calculator official?
No. It uses the most commonly published formulas. Individual universities in the USA may weight or round differently — always confirm on your official transcript.
