Frequently asked questions
How is GPA calculated?
Each letter grade converts to points (A = 4.0, A− = 3.7, B+ = 3.3 …), each course's points are multiplied by its credit hours, and the total grade points are divided by total credits. That's why high-credit courses move your GPA more.
What's the difference between weighted and unweighted GPA?
Unweighted caps at 4.0 regardless of course difficulty. Weighted scales (common in high schools) add bonus points for honors and AP/IB courses, often making an A worth 4.5 or 5.0. This calculator computes the unweighted 4.0 version; your school's transcript is authoritative for the weighted number.
Does an A+ count more than an A?
Usually not — most schools cap both at 4.0, which is how this calculator treats it. A minority of institutions award 4.3 for an A+; check your school's policy if it matters for your math.
How much can one semester move my cumulative GPA?
It depends on how many credits you already have — the more accumulated credits, the more inertia. A 4.0 semester of 15 credits lifts a 3.0 GPA on 45 existing credits to about 3.25. Early semesters move the number most.
About this tool
The GPA calculator computes your grade point average on the standard 4.0 scale: add each course with its letter grade and credit hours, and the weighted average updates live along with total credits and grade points. It uses the common scale where A = 4.0, with each plus or minus stepping 0.3 points (A− = 3.7, B+ = 3.3, and so on down to F = 0). Credits weight the average, so a 4-credit A lifts your GPA more than a 1-credit A. Use it to project a semester GPA before grades post, model how next term's courses would move your cumulative number, or translate a report card for applications.
