High School GPA Calculator
Calculate weighted or unweighted high school GPA from your classes, grades and credits.
Use CalculatorEnter your current cumulative GPA and credits, then add this semester's classes to see what your new cumulative GPA will be.
Enter your current cumulative GPA and the total credits you've completed — both are on your transcript or student portal.
Add each course you're taking this semester with the grade you expect and its credit hours. The calculator shows your semester GPA and your projected new cumulative GPA as you type.
Try different expected grades to see what you need to reach a goal. Need your semester GPA on its own? Use the High School GPA Calculator, or browse all Grade & GPA Calculators.
New GPA = (current GPA × credits done + semester quality points) ÷ total credits
Classes with more credits pull your cumulative GPA harder. The more credits you've completed, the less one semester can move it.
New courses use the unweighted 4.0 scale shown next to the result.
Illustrative example
You have a 3.2 GPA over 30 credits (96 quality points). This semester you earn an A in all 15 credits: 15 × 4.0 = 60 points.
New cumulative GPA = (96 + 60) ÷ 45 = 3.47.
