Grade Calculator

Calculate letter grades, GPA, and academic performance with comprehensive grading scales and honor roll calculations. Perfect for students, teachers, and academic advisors.

Understanding Grade Calculation

Grade calculation is a fundamental aspect of academic assessment that converts numerical scores into letter grades and grade point averages (GPA). This comprehensive calculator supports multiple grading scales, course credit weighting, and honors recognition systems used in educational institutions worldwide.

The grading process involves converting percentage scores to letter grades, then to grade points, which are weighted by course credits to calculate cumulative GPA. Different institutions may use varying scales, but the most common systems in the United States are the 4.0 and 5.0 scales.

GPA Calculation Methods

Unweighted GPA

Unweighted GPA uses the standard 4.0 scale regardless of course difficulty:

• •All courses count equally toward GPA
• •Standard grade point values apply
• •No additional points for honors or AP courses

Weighted GPA

Weighted GPA accounts for course difficulty:

• •**Regular Courses**: Standard grade points
• •**Honors Courses**: +0.5 additional grade points
• •**AP/IB Courses**: +1.0 additional grade points
• •**College Courses**: +1.0 additional grade points

Cumulative GPA Formula

Cumulative GPA = Total Grade Points ÷ Total Credits

Where:

• •Total Grade Points = Σ (Course Grade Points × Course Credits)
• •Total Credits = Σ (Course Credits)

Latin Honors (College)

• •**Summa Cum Laude**: Top 5% of class
• •**Magna Cum Laude**: Top 10% of class
• •**Cum Laude**: Top 25% of class

National Honor Society

• •**Minimum GPA**: 3.5 (unweighted)
• •**Leadership**: Demonstrated leadership experience
• •**Service**: Community service involvement
• •**Character**: Good character and discipline record

Course Credit Systems

Semester Credits

• •**Standard Course**: 1.0 credit (full year) or 0.5 credit (semester)
• •**Half Credit Course**: 0.5 credits (often electives)
• •**Lab Course**: Additional 0.25-0.5 credits

Quarter Credits

• •**Standard Course**: 3-5 credits per quarter
• •**Lab Course**: 1-2 additional credits
• •**Seminar Course**: 1-2 credits

Credit Conversion

• •**Semester to Quarter**: Semester credits × 1.5 = Quarter credits
• •**Quarter to Semester**: Quarter credits ÷ 1.5 = Semester credits
