How it works

Enter each course name, then either a letter grade (A, B+, C-) or a number (0-100), and the credit hours. Click Calculate GPA to get your weighted GPA and percentage.

Grade Scale (Default)

Letter	Numeric Range	Grade Point
A	93-100	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-	70-72	1.7
D	60-69	1.0
F	<60	0.0

You can customize the mapping in the code if your school uses a different scale.

FAQ

Q: Can I use numeric marks?
A: Yes — type e.g. 85 or A, both are accepted.

Q: Does it handle pass/fail?
A: You can mark pass as P and assign credits manually; the tool ignores P for GPA unless you choose to map it.

Complete Guide to GPA & Grade Calculation

Understanding how GPA (Grade Point Average) and percentages work is essential for students, parents, and educators. This tool allows you to calculate your weighted GPA, convert percentages to GPA, and check how letter grades correspond to numeric scores. Below, we provide a detailed guide on how GPA is calculated, common grading systems, and examples for better clarity.

📘 What is GPA?

GPA, or Grade Point Average, is the numerical representation of your academic performance. Most institutions use a 4.0 scale, where:
A = 4.0, B = 3.0, C = 2.0, D = 1.0, and F = 0.0. Some universities may also use a 5.0 or 10-point scale.

🎯 Types of GPA

Unweighted GPA – Calculated on a 4.0 scale without considering course difficulty.
Weighted GPA – Considers course difficulty (AP, Honors, IB) where an A in Honors may count as 4.5–5.0.
Cumulative GPA – The average of all courses taken across semesters/years.

🧮 How GPA is Calculated

Convert each course grade into grade points (A = 4.0, B+ = 3.3, etc.).
Multiply grade points by the credit hours of that course.
Add all grade points together.
Divide by the total credit hours.

Example:
- Math (A, 3 credits) = 4.0 × 3 = 12
- English (B+, 4 credits) = 3.3 × 4 = 13.2
- Science (B, 2 credits) = 3.0 × 2 = 6
Total = 31.2 ÷ 9 credits = 3.47 GPA

📊 GPA vs Percentage Conversion

Many students wonder how GPA relates to percentage. A common conversion chart is:

Percentage	GPA (4.0 scale)	Letter Grade
93–100	4.0	A
90–92	3.7	A-
87–89	3.3	B+
83–86	3.0	B
80–82	2.7	B-
70–79	2.0–2.3	C
60–69	1.0	D
<60	0.0	F

🌍 GPA Scales Around the World

USA & Canada: 4.0 scale (sometimes weighted up to 5.0).
India: Percentage or 10-point CGPA.
UK: Class system (First Class, 2:1, 2:2, Third).
Europe (ECTS): A–F grading.
Australia: HD (High Distinction), D, C, P, F.

💡 Tips to Improve GPA

Stay consistent with assignments and classwork.
Focus more on subjects with higher credit hours since they impact GPA more.
Use a study planner and revise regularly.
Retake courses where allowed to replace low grades.
Balance challenging courses with easier ones to keep GPA stable.
