How It Works
Enter each course with its letter grade and credit hours. The calculator multiplies grade points by credits, sums everything up, and divides to give your exact GPA on the 4.0 scale.
What You Can Do
Calculate your semester GPA, track cumulative performance over time, convert CGPA to a percentage for job applications, or plan what grades you need to hit your goal.

How the GPA Calculator Works
The GPA calculator uses a weighted average formula to convert your letter grades into a single number. Here is the process step by step:
Step-by-Step Breakdown
Type in each course you have completed. The course name is optional — all that matters is the grade and the number of credit hours.
Every letter grade has a fixed point value on the 4.0 scale. An A is worth 4.0, an A- is 3.7, a B+ is 3.3, and so on down to an F which is 0.0.
For every course, multiply its grade points by its credit hours. A B (3.0) in a 4-credit course produces 12 quality points.
Sum all quality points across every course, then sum all the credit hours separately.
Divide total quality points by total credit hours. That result is your GPA — ready to use on applications, transcripts, or scholarship forms.
GPA Calculation Formulas
Standard GPA Formula
Credit Hours = the weight assigned to each course
Σ = sum across all courses

Understanding Your GPA
Your Grade Point Average is the single number colleges, employers, and scholarship committees use to compare academic performance across different schools and programs. Knowing how it works gives you more control over your academic outcomes.
Why GPA Matters
GPA appears on college applications, graduate school forms, scholarship applications, and many job applications. A strong GPA opens doors; understanding where yours stands helps you decide where to focus your energy.
Three Things That Shape Your GPA
- Letter Grades: Converted to points on the 4.0 scale — A through F.
- Credit Hours: Heavier courses (more credits) have a bigger impact on your average.
- Quality Points: The product of grade points × credit hours for every course.
Weighted vs. Unweighted
An unweighted GPA treats every course equally. A weighted GPA adds bonus points for advanced courses — typically +0.5 for Honors and +1.0 for AP or IB. Check which system your school uses before submitting applications.
Real-World Example: College Application GPA
A student is applying to university and needs their cumulative GPA for the application form.
- English — A- (3.7) × 4 credits = 14.8 quality points
- Mathematics — B+ (3.3) × 5 credits = 16.5 quality points
- History — A (4.0) × 3 credits = 12.0 quality points
- Science — B (3.0) × 4 credits = 12.0 quality points
Total quality points = 14.8 + 16.5 + 12.0 + 12.0 = 55.3
Total credit hours = 4 + 5 + 3 + 4 = 16
Semester GPA = 55.3 ÷ 16 = 3.46
A 3.46 sits solidly in the B+ range — strong performance that meets the requirements for most universities and many merit scholarships.
