GPA Scale
Use this GPA scale to convert a letter grade or percentage grade into grade points on a 4.0, 4.3, or 4.33 scale. The calculators on CalcMyGrades use this same conversion table for GPA-eligible letter grades. F counts as 0.0 grade points, while P, NP, W, and I are excluded from GPA calculations.

| A+ | 97-100% | 4.0 | 4.3 | 4.33 |
| A | 93-96% | 4.0 | 4.0 | 4.0 |

What Is the GPA Scale?
GPA means Grade Point Average. Schools use it to summarize academic performance across several classes, semesters, or years. GPA can affect college admissions, graduate program eligibility, scholarships, financial aid, and some early-career job opportunities.
A GPA is not a separate grade by itself. It is a calculation based on letter grades. Each letter grade is assigned a grade point value, and those grade points are averaged according to the calculation rules for the school or program.
Percentages, Letter Grades, and Grade Points
Most classes begin with a percentage grade. A teacher or school converts that percentage into a letter grade, such as A, B+, or C-. The GPA scale then converts the letter grade into grade points. For example, a 95% may become an A, and an A is worth 4.0 grade points on the standard 4.0 scale.
Once each class has a grade point value, the final GPA can be calculated. College GPA usually multiplies grade points by course credits before averaging. High school GPA usually treats each class equally, and weighted high school GPA adds extra points for Honors, AP, or IB classes before the average is calculated.
Why There Are Three GPA Scales
The 4.0 scale is the most common GPA scale. Some schools use a 4.3 or 4.33 scale so that an A+ can receive more value than an A. On CalcMyGrades, choose the scale that matches your school policy. The selected scale controls the grade points used in every GPA calculation.
Available scales: Standard 4.0, Standard 4.3, Standard 4.33.
