Mathematical Formula & Variables

Equation ModelUnweighted GPA = \frac{\sum (GradePoints \times Credits)}{\sum Credits}, \quad Weighted GPA = \frac{\sum ((GradePoints + WeightBonus) \times Credits)}{\sum Credits}

Unweighted GPA measures academic performance on a standard 4.0 scale regardless of course rigor. Weighted GPA adds an extra weight bonus (+1.0 for AP/IB/Dual Enrollment, +0.5 for Honors) to reflect advanced academic difficulty.

Variable Definitions

SymbolDescription
GradePointsBase numerical point value of letter grade (A=4.0, B=3.0, C=2.0, D=1.0, F=0.0)
WeightBonusAdditional weight bonus for course difficulty (AP/IB/Dual Enrollment = +1.0, Honors = +0.5, Regular = 0.0)
CreditsCourse credit value (typically 0.5 for semester or 1.0 for full-year course)
TotalCreditsSum of all attempted academic course credits

How to Use the High School GPA Calculator

  • Add all your high school classes for the current semester, school year, or full high school career.
  • Select the letter grade received or expected for each course (from A+ down to F).
  • Specify the credit value for each class (e.g., 0.5 credit for semester courses, 1.0 credit for full-year courses).
  • Select the course level (Regular, Honors, AP, IB, or Dual Enrollment/College Level).
  • Optionally enter your prior cumulative GPA and prior earned credits to calculate your updated overall cumulative GPA.
  • Instantly view your unweighted 4.0 GPA, weighted 5.0 GPA, total credits earned, and graduation academic honors status.

High School Semester GPA Calculation Example

Scenario Context: A high school junior takes 4 classes: AP Biology (A, 1.0 credit), Honors Pre-Calculus (B+, 1.0 credit), AP US History (A-, 1.0 credit), and Regular English 11 (A, 1.0 credit). Calculate both unweighted and weighted GPA.

Step 1: 1. Determine Base Grade Points: AP Biology (A = 4.0), Honors Pre-Calc (B+ = 3.3), AP US History (A- = 3.7), Regular English (A = 4.0).
Step 2: 2. Calculate Unweighted Quality Points: (4.0×1.0) + (3.3×1.0) + (3.7×1.0) + (4.0×1.0) = 4.0 + 3.3 + 3.7 + 4.0 = 15.0 points.
Step 3: 3. Compute Unweighted GPA: 15.0 total points / 4.0 total credits = 3.75 unweighted GPA.
Step 4: 4. Add Course Weight Bonuses: AP Bio (4.0 + 1.0 = 5.0), Honors Pre-Calc (3.3 + 0.5 = 3.8), AP US History (3.7 + 1.0 = 4.7), Regular English (4.0 + 0.0 = 4.0).
Step 5: 5. Calculate Weighted Quality Points: (5.0×1.0) + (3.8×1.0) + (4.7×1.0) + (4.0×1.0) = 5.0 + 3.8 + 4.7 + 4.0 = 17.5 points.
Step 6: 6. Compute Weighted GPA: 17.5 total points / 4.0 total credits = 4.375 weighted GPA.
The student earned an Unweighted GPA of 3.75 on a 4.0 scale and a Weighted GPA of 4.38 on a 5.0 scale across 4.0 credits.
