GPA Calculator

Convert grade points per subject into overall GPA and percentage.

Overview

Calculates single-semester Grade Point Average (GPA) on a 4.0 or 10.0 scale by weighting individual course letter grades by their assigned credit hours.

Formula & Calculation Method

GPA = Sum of (Course Credit Hours × Grade Point) / Total Semester Credit Hours

Standard 4.0 scale mappings: A (4.0), A- (3.7), B+ (3.3), B (3.0), B- (2.7), C+ (2.3), C (2.0), D (1.0), F (0.0).

Worked Example: 4 Courses Completed in a Semester on 4.0 Scale

Inputs: Math (4 cr, Grade A=4.0) | Physics (3 cr, Grade B+=3.3) | English (3 cr, Grade A-=3.7) | Lab (1 cr, Grade A=4.0)

  • Quality points = (4 × 4.0) + (3 × 3.3) + (3 × 3.7) + (1 × 4.0) = 16.0 + 9.9 + 11.1 + 4.0 = 41.0 points
  • Total semester credits = 4 + 3 + 3 + 1 = 11 credits
  • Semester GPA = 41.0 / 11 = 3.73 GPA

Summary: Total Credits = 11 | Quality Points = 41.0 | Semester GPA = 3.73 / 4.0 (Dean's List)

Common Use Cases

  • Semester Academic Tracking: Calculate term GPA to verify eligibility for academic honors and scholarships.
  • Grading Strategy: Determine which course grades require greatest study focus to maximize semester GPA.
  • Exchange Student Conversion: Convert European ECTS or Asian grading scales to standard US 4.0 GPA.

Frequently Asked Questions

What is a good GPA on a 4.0 scale?

A 3.0 (B average) is standard; 3.5+ qualifies for Dean's List honors; 3.8+ is competitive for top-tier graduate schools.

Do Pass/Fail or Withdrawn (W) grades affect GPA?

Pass/Fail and official course withdrawals (W) do not impact GPA; however, failing a Pass/Fail course (Fail) may count as 0.0 points in some colleges.

How do credit hours affect my GPA?

Credit hours represent weighting: getting an A in a 4-credit course provides four times the grade points of getting an A in a 1-credit course.
