GPA Calculator
Calculate your GPA from course grades and credit hours on the standard 4.0 scale.
About GPA Calculator
A GPA calculator converts letter grades and credit hours into the single grade point average that schools, scholarships, and employers look at. Manually weighting grades by credit hours is exactly the kind of arithmetic that invites mistakes, especially across a whole semester of courses.
The standard 4.0 scale maps A = 4.0, B = 3.0, C = 2.0, and D = 1.0, with common plus/minus values like A− = 3.7 and B+ = 3.3. GPA = sum of (grade points × credits) ÷ total credits. Because it is weighted by credit hours, a 4-credit A outweighs a 1-credit A, which keeps the average fair across different course loads.
College students track their standing and project what grades they need to raise it, high schoolers planning applications estimate where they stand, and advisors verify calculations when students ask about academic standing. It is also useful for comparing the difficulty of different course combinations before registration.
How to Use
- Add each course with its letter grade and credit hours.
- Add more rows until every course is listed.
- Read your GPA and total credit hours.
Example
A (4.0) × 3 credits, B (3.0) × 4 credits GPA 3.43
GPA = (4.0×3 + 3.0×4) ÷ (3+4) = 24 ÷ 7 = 3.43, weighted by credit hours.
FAQ
How are plus/minus grades handled?
Common plus/minus values like A- (3.7) and B+ (3.3) are supported, selectable per course.
Can I use it for a weighted GPA?
This uses the standard unweighted 4.0 scale. Weighted scales vary by school, so check your institution's policy.
Why are credit hours weighted?
A 4-credit A should count more than a 1-credit A. Weighting by credits is what makes a GPA fair across different schedules.
How do pass/fail courses affect my GPA?
They do not affect the grade point average. Credit hours from pass/fail courses still count toward your degree, but the pass grade carries no numeric points, so the GPA only reflects graded coursework.
Can I use this for a 5.0 or weighted scale?
The tool uses the standard unweighted 4.0 scale. Weighted scales, which add points for honors or AP classes, vary by school, so convert your grades to 4.0 equivalents first or check your institution's policy.
