GPA Calculator
Calculate GPA and cumulative GPA
About the GPA Calculator
Your GPA condenses a semester of grades into a single number, but calculating it means weighting each course by its credit hours — and weighting honors or AP classes higher still. This calculator handles all of that: enter each course's grade, credits, and type, and it computes your semester GPA, with an option to roll in your previous record for a cumulative figure.
Students use it to project a semester before grades are final, to see how one class will move their average, or to confirm a registrar's number. Support for weighted course types and a 4.0 or 5.0 scale means it works for standard transcripts and weighted honors systems alike.
How to Use the GPA Calculator
- Choose the 4.0 or 5.0 GPA scale.
- Add each course with its grade, credit hours, and type (regular, honors, AP, or IB).
- Optionally enter your previous GPA and total credits for a cumulative result.
- Read your semester GPA, cumulative GPA, total credits, and a grade breakdown.
Why Use ToolForge’s GPA Calculator
- It weights honors, AP, and IB courses above regular ones, reflecting how weighted GPAs are actually calculated rather than treating every course equally.
- It supports both the 4.0 and 5.0 scales and computes a cumulative GPA when you supply prior credits.
- It shows total quality points and a per-grade breakdown, so you can see exactly how the average was built.
- Calculations happen in your browser with no account.
Frequently Asked Questions
How is GPA calculated?
Each course's grade is converted to grade points, multiplied by its credit hours (and a weight for honors or AP), to give quality points. GPA is the total quality points divided by the total credits, so higher-credit courses count more toward the average.
What is the difference between weighted and unweighted GPA?
An unweighted GPA treats every course on the same scale, while a weighted GPA gives extra points to harder courses like honors, AP, or IB. This calculator applies those weights when you mark a course's type, raising its contribution to the average.
How do I calculate my cumulative GPA?
Enter your previous cumulative GPA and the total credits it covers, alongside this semester's courses. The calculator combines the prior quality points with the new ones to produce an updated cumulative GPA across all credits.
What GPA scale should I use?
Use the scale your school reports on — 4.0 is the most common unweighted scale, while 5.0 scales are often used where weighted honors and AP grades can exceed 4.0. The toggle lets you match whichever your institution uses.
