Frequently asked questions

What is GPA and how is it calculated?

GPA stands for Grade Point Average. It is calculated by dividing the total quality points (grade points × credits) by the total credits attempted.

Does this calculator support weighted GPA for Honors or AP classes?

Yes. Select +0.5 for Honors or +1.0 for AP/IB courses to automatically apply the weight.

Can I calculate cumulative GPA across multiple semesters?

Yes. Use the Cumulative mode: enter your previous GPA and credits, then add current semester courses.

How do I find out what GPA I need this semester to reach my target?

Switch to Target Planner mode and enter your current stats plus desired cumulative GPA and future credits.

What grading scale does this tool use?

Standard US 4.0 scale with plus/minus (A+ = 4.3, A = 4.0, down to F = 0.0).

Is this GPA calculator accurate for college and high school?

Yes. It works for both. Always confirm final official GPA with your school registrar.

Can I use this for GPA without credits?

No. This tool requires credit hours as they are essential for accurate weighted calculation. For unweighted simple average, average your grade points directly.

Does it save my data?

No. Calculations are private and happen only in your browser. Refreshing the page resets the form.

What is a good GPA?

Generally, 3.0+ is solid, 3.5+ is strong for competitive colleges, and 3.7+ is excellent.

Why does my school’s GPA differ from this calculator?

Some schools use different scales or weighting policies. Use this as an estimate and verify with your official transcript.
