GPA Calculator
Calculate weighted GPA from letter grades and credit hours
What is the GPA Calculator?
A GPA calculator figures out your Grade Point Average, the number that colleges, universities, and graduate programs use to measure academic performance. Whether you're trying to check if you've met a minimum GPA requirement, predict how this semester will affect your cumulative average, or plan which grades you need to hit your target, this tool does the math directly. CalciHub's GPA calculator handles both semester GPA and cumulative GPA, and works across different credit-hour systems.
How Does It Work?
GPA is a weighted average where each course's grade points are multiplied by its credit hours.
Formula:
GPA = Total Grade Points ÷ Total Credit Hours
Grade points per course = Grade Point Value × Credit Hours
Standard 4.0 scale:
A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0, B- = 2.7
C+ = 2.3, C = 2.0, C- = 1.7, D = 1.0, F = 0.0
How to Use CalciHub's GPA Calculator
1. Enter each course name (optional) and its credit hours.
2. Select or type the letter grade you received (or expect to receive) for each course.
3. Add as many courses as needed using the 'Add Course' option.
4. The calculator shows your GPA instantly as you enter each course.
Tip: Use the 'What GPA do I need?' feature if you want to work backward, enter your current GPA and credits and set a target GPA to find out what grades the remaining courses must be.
A Quick Example
A student finishes a semester with four courses and wants to know their GPA.
Biology (4 credits) — A (4.0): 4 × 4.0 = 16.0
History (3 credits) — B+ (3.3): 3 × 3.3 = 9.9
Math (3 credits) — B (3.0): 3 × 3.0 = 9.0
English (2 credits) — A- (3.7): 2 × 3.7 = 7.4
Total grade points: 42.3
Total credits: 12
GPA: 42.3 ÷ 12 = 3.525
Output: 3.53 GPA
That's a solid semester, well above a 3.0 and competitive for most graduate programme applications.
Frequently Asked Questions
It depends heavily on context. A 3.5 is generally considered strong at a four-year university. Medical and law school applicants typically target 3.7 or higher. For competitive scholarships, some programmes expect 3.8+. That said, GPA is one factor among many — not a single defining number.
Not exactly. Most US universities use a 4.0 scale, but some use 4.3 or 5.0 scales. Some schools weight honours or AP courses differently. Always check your institution's specific grading scale before relying on a general calculator.
Semester GPA covers only the current term. Cumulative GPA averages all coursework across every term you've completed. A bad semester won't tank a cumulative GPA built over years — though it does affect it.
Policies vary by school. Some replace the original grade entirely with the new one. Others average both. A few keep both grades on the transcript but only count the higher one in GPA calculations. Check your school's retake policy specifically.
