About the GPA Calculator
GPA — Grade Point Average — is the credit-weighted average of your course grades. Each grade converts to a point value (A = 4.0, B+ = 3.3, and so on), each course’s points are multiplied by its credit hours, and GPA = total grade points ÷ total credits. The weighting is the part people get wrong when calculating by hand: a 4-credit B pulls your GPA more than a 2-credit A lifts it.
A worked example
Three courses: Mathematics, 3 credits, grade A (4.0) → 12.0 points. Physics, 4 credits, grade B+ (3.3) → 13.2 points. English, 2 credits, grade A− (3.7) → 7.4 points. Total: 32.6 grade points over 9 credits = GPA 3.62. A straight average of the three grades (3.67) would overstate it — the 4-credit B+ carries the most weight, which is exactly what the credit system is designed to do.
What the numbers mean
On the 4.0 scale, 3.7+ is typically Dean’s-List territory, 3.0–3.7 solid, and below 2.0 academic-probation risk at most institutions. Many scholarships and graduate programmes publish GPA cutoffs (3.0 and 3.5 are the common bars) — this calculator answers “what grades do I need this semester to stay above the bar” by letting you add hypothetical courses and watch the GPA move.
4.0 scale vs 10-point scale
US-style institutions grade on 4.0 with letters; most Indian universities award grade points out of 10 per course and report a semester SGPA / cumulative CGPA. This calculator handles both — switch to the 10-point mode and type grade points directly. To convert a final CGPA into the percentage that job portals ask for, use the CGPA to Percentage Converter; for raw marks, the Marks Percentage Calculator. All free, all in your browser.
Frequently Asked Questions
How is GPA calculated?
Each grade converts to points (A = 4.0, B+ = 3.3…), multiplied by the course’s credits; GPA = total grade points ÷ total credits. A 4-credit course moves your GPA twice as much as a 2-credit one.
What is a good GPA?
On the 4.0 scale, 3.7+ is excellent (Dean’s List range), 3.0–3.7 is solid, and below 2.0 risks academic probation at most institutions. Scholarships commonly set 3.0 or 3.5 cutoffs.
What’s the difference between GPA and CGPA?
GPA usually refers to one semester (or the 4.0-scale average); CGPA is the cumulative average across all semesters, often on a 10-point scale in India. This calculator handles both scales.
How do I convert my CGPA to a percentage?
Use your university’s official formula — commonly CGPA × 9.5 (CBSE) or (CGPA − 0.75) × 10 (VTU/Anna). Our CGPA to Percentage Converter applies whichever rule your university uses.
Can I calculate what I need next semester?
Yes — add hypothetical courses with target grades and watch the GPA update. It’s the quickest way to see what keeps you above a scholarship or probation cutoff.
