How to use

  1. 1Enter each course with its letter grade and credit hours.
  2. 2The 5.0 scale awards higher grade points for advanced work — an A in Honors or AP typically earns 4.5 or 5.0.

Formula

GPA = Σ (grade point × credits) / Σ credits, where grade points range from 0.0 to 5.0
VariableNameMeaning & Example
AP / IB ATop Grade APGrade of A in Advanced Placement or IB class (5.0 points)
Honors ATop Grade HonorsGrade of A in Honors course (4.5 points)
Standard ATop Grade RegularGrade of A in standard high school class (4.0 points)

On a 5.0 weighting scheme, standard courses and advanced courses use different grade points, with the scale capped at 5.0 for the highest honors or AP grades. Each course's point value is multiplied by its credits, summed, and divided by total credits.

Examples

AP A (4cr) = 5.0, Honors B+ (4cr) = 3.8, Standard A- (3cr) = 3.7

QP: 20.0 + 15.2 + 11.1 = 46.3 ÷ 11.

Frequently asked questions

Why does my GPA exceed 4.0 on this scale?
Because weights can reach 5.0 for the hardest courses. A perfect advanced course schedule yields a 5.0 GPA.
What weights should I assign?
Follow your high school's calendar: commonly Honors +0.5 and AP/IB +1.0 over the base 4.0 values.
How do you convert a 5.0 GPA scale to a 4.0 scale?
You cannot simply multiply by 4/5 because weighted bumps distort the base. To convert accurately, subtract the +1.0 and +0.5 bonus points for AP and Honors classes, reverting all grades to their base 4.0 values.
What is considered a good GPA on a 5.0 scale?
A GPA of 4.0 to 4.5 on a 5.0 weighted scale indicates strong performance across honors and advanced classes, while 4.5+ represents upper-percentile academic achievement.
