GPA Calculator

Calculate your semester GPA on a 4.0 scale from your courses, with optional honours and AP weighting, and see how many more credits at an A you need to reach a target GPA.

Add a row for each course, then enter its credit hours, letter grade and level (regular, honours or AP). The calculator returns your unweighted GPA, weighted GPA, total credits and the credits needed at an A to reach your target.

A Grade Point Average (GPA) summarises your grades on a 4.0 scale, weighted by each course's credit hours. A weighted GPA gives extra weight to honours and AP/IB classes, which many US high schools use for class ranking.

The maths

GPA = Σ (grade point × credits) / Σ credits

Grade points: A=4.0, A−=3.7, B+=3.3, B=3.0, B−=2.7, C+=2.3, C=2.0, C−=1.7, D+=1.3, D=1.0, F=0. Weighted: honours +0.5, AP/IB +1.0 (capped at 5.0).

Examples

  • Two B's (3 cr each) = 3.0 GPA
  • An A in a 4-cr AP class lifts a weighted GPA more than in a regular class
  • To raise a 3.2 to 3.5, you need high grades in your heaviest-credit courses

Frequently asked questions

What's the difference between weighted and unweighted?

Unweighted GPA ignores course difficulty (max 4.0). Weighted GPA adds points for honours/AP/IB courses, so it can exceed 4.0 and rewards taking harder classes.

Do all schools use this scale?

No. Scales vary — some use percentages, some a 5.0 or 12.0 scale, and weighting policies differ. Treat this as a standard US 4.0-scale estimate.
