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.

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.

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.
