Is this the same GPA my school will publish?

It mirrors common high-school weighted math, but every district sets its own rounding, weight caps, and excluded courses. Treat the on-screen numbers as planning estimates and confirm with your registrar or handbook.

Where is my data stored?

Semesters and courses stay in your browser’s local storage on this device. Clearing site data or using private browsing removes them—we never upload your grades to a server.

When should I switch to the college GPA calculator?

As soon as you need true credit-hour weighting (typical dual enrollment or university transcripts). The college variant uses the same layout but emphasizes semester credit totals.

How do I calculate GPA from letter grades and credits?

Convert each letter to grade points, multiply by credits, sum those products, then divide by total credits. This workspace does that math live for each semester and for the cumulative line.

Does weighted GPA use a 5.0 scale?

Some schools cap at 5.0 or use different bumps. Our weighted toggle applies typical honors/AP-style increases—match your handbook if your district uses another table.

Can I model a future semester before grades post?

Yes. Add a semester, enter planned courses and expected grades, and watch how the cumulative gauge moves before you lock course requests.

GPA context benchmarks (planning reference)

Use these widely cited planning bands to interpret your calculated GPA. They are not admission guarantees—always confirm with each school.

Profile	Typical GPA band	Notes
Highly selective universities	3.9+ weighted / 3.8+ unweighted	Varies by major; rigor and test scores matter equally.
Top ~10% of class (national planning band)	3.8 – 4.0	Common merit scholarship threshold at many schools.
U.S. high school average (NCES reporting)	~3.0 – 3.2	Unweighted approximations; districts differ.
NCAA academic eligibility planning	2.3+ core GPA (Division I baseline)	See NCAA sliding scale for test-score pairings.

Sources include NCES high school transcript reports, NCAA eligibility guides, and published admission profiles. Figures are rounded for planning—not official cutoffs.

Formula & how the math works

Unweighted semester GPA is quality points ÷ credits. Each course contributes grade points × credits; sum those products, then divide by total credits in the term.

Cumulative GPA uses the same idea across every included semester: total quality points ÷ total credits. Weighted mode adds school-style bumps to grade points before the division.

GPA = Σ(grade points × credits) ÷ Σ(credits)

How to use the GPA calculator

This workspace combines semester blocks, per-course letter grades, credits, and an optional weighted policy so you can see both term and cumulative GPA on one screen.

Each semester lists courses with grade, credits, and weight (for high-school style weighting).
Turn Weighted on when you want honors/AP-style bumps applied to that term.
Add semesters or courses as needed; totals refresh automatically.

When to use this calculator

Align credits and weight rules with your transcript or handbook before sharing numbers with advisors.
Snapshot your term mid-semester to see how one grade change moves the average.
Pair this tool with our GPA scale pages when converting between letters and percentages.

Examples & walkthrough

Start with Semester 1: enter a course name (optional), pick a letter grade, and set credits (often 1.0 per class in high school).
Choose a course weight if your school distinguishes regular, honors, or AP-style rigor.
Use + Add Course for more rows, or add another semester when a new term begins.
Watch the semester GPA line and the cumulative gauge update as you edit inputs.
For college credit-hour math, open the dedicated College GPA calculator.
